The price of raw materials rises and the cost of passive components rises.
Passive components are mainly divided into three families: resistors, capacitors, and inductors, many of which are made of copper and aluminum.
The price of copper clad laminate (CCL) has risen recently, and the source is the rise in copper prices. The situation in the aluminum market is the same as that in the copper market. They both started to rise at the end of the first quarter and have accumulated a lot of gains.
With the recovery of market demand, the prices of copper and aluminum can be adequately supported. For passive component manufacturers, the price increase of copper and aluminum will increase the cost of raw materials, and price increases to ensure profits may occur frequently.

Several major markets have recovered and demand for passive components has increased.
With the development of the 5G industry chain, electric vehicles and other fields, the PC and server market demand caused by the "home economy" caused by the epidemic remains unchanged. In general, several important markets around the world are recovering in the fourth quarter, which will also stimulate the growth of passive component market demand.
In many industry sectors, the 5G industry chain and new energy vehicles have the largest increase in demand for passive components, and they are also key projects that are supported.

In the future, under the background of strong new energy vehicles, the demand for passive components will also increase sharply. In the 5G industry, both mobile phone business and new base stations are inseparable from the demand for passive components, and they are more than ever.

Major factories suspend production, may be the final push for price increases.
At a time when the supply and demand relationship in the passive component market is tight, the original factory has stopped production again, which may directly break the market balance and become the ultimate driver of price increases.

According to the latest report from Taiwanese media, Taiwan's passive component factory Walsin Malaysia factory has an employee infected with the epidemic. Currently, production is temporarily suspended and is planned to be suspended for three weeks. Affected products may include car gauge resistors, 0201 resistors and high-energy resistors.
The current critical period for demand recovery is that the original passive component factory is too late to expand production. This time, instead, a new gap has been created due to the suspension of production by Walsin. Next, it depends on how many transfer orders from Walsin can be absorbed by Yageo and Chilisin, and whether they will take advantage of the situation to raise prices.

According to the latest situation, the price increase of passive components will come earlier than expected, and the possibility that the market will start at the end of the year will greatly increase. All of us should take countermeasures from now on to prevent sudden changes in the market from being caught off guard.

A wide range of applications coupled with low costs and high accuracy make NKT NTC thermistors a frequently used device. The applications performed by these devices allows for thermistors to function as accurately as they do. NKT NTC Thermistors are used in a wide range of different industries that require high accuracy when it comes to temperature. Some of the applications include:

Temperature compensation: considering that temperatures fluctuate as a result of their environment, NTC thermistors are able to compensate for changes to keep temperature where it needs to be. Examples of circuits that might require compensation are, LCD displays, charging batteries, oscillators, HVAC( Heating, Ventilation and Air Conditioning) and refrigeration equipment

Inrush current limiting: not only is a NTC thermistor subject to a change in temperature, but it is also susceptible to changes in power. When there are changes in power, a NTC thermistor experiences a time lag prior reaching lower resistance. The time lag is utilized to help limit the inrush surge currents. It used for medical industry including catheters, dialysis equipment, and patient monitoring.

Temperature measurement: If low cost, longevity, and accuracy are important qualities, a NTC thermistor is the best option. For the operating of dryers, coffee devices. Automotive and aerospace industries use NKT NTC thermistors for test and measurement as well as production applications

Fluid level gauging: A thermistor will be able to sense an absence or presence of a liquid. It is able to do this through measuring the difference between dissipation constants (between a gas and a liquid).

Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set
C. Physical and environmental conditions
D. Stability of setting required
E. Circuit packaging requirements 

C. Physical and Environmental Issues

1. Physical considerations in trimmer selection
• Case style desired
• Top or side adjust
• Pin style required
• Mechanical support required
• Board height requirements

2. Assembly process considerations
BI offers a variety of trimmer models that are sealed to help protect against moisture and board washing processes.
•Open vs. Sealed
• Max time/temperature exposure 

3. Environmental operating considerations
• Operating temperature range
• Resistance temperature coefficient
• Vibration and shock tolerance 

4. Human operating conditions When you complete your design, be careful to consider the tortures that clever human beings with a screwdriver in hand can impose on trimmers. For example, while a trimmer configuration mounted on edge might be a board space saver, a trimmer that mounts flat on the board may be more resistant to abuse by a heavy handed technician making adjustments through a hole in the chassis.

Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set
C. Physical and environmental conditions
D. Stability of setting required
E. Circuit packaging requirements

B. Setability and Time to Set
The enemies of setability are poor resolution, mechanical backlash and high CRV. BI has addressed these problems in the design of trimmer models. BI’s smooth cermet materials, precious metal split brush contacts and teflon rotors work together to provide outstanding setability.

“Time to set” tests show the following:

Setting Attributes	Single Turn	Multiturn
High accuracy		Best
Fastest to high accuracy		Best
Fastest to approximate setting	Best

II. Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set
C. Physical and environmental conditions
D. Stability of setting required
E. Circuit packaging requirements

A. Resolution of Adjustment
1. Multiturns
• Multiturns provide better resolution than single turns. Models with a longer element exhibit better resolution than those with a short element. Typical multiturn shaft revolutions range from 15 to 20 turns for end to end travel.
• The contact design and stability are important considerations in achieving high resolution. The contact area must be small and the contact must move smoothly in order to provide high resolution. A noisy contact will make accurate setting very difficult.
• All trimmers utilize smooth cermet materials, precious metal wire brush contacts and backlash-free wiper designs that ensure high resolution setability.
• Reference multiturn models:
Square multiturns - 44, 64, 66, 67, 68
Rectangular multiturns 78, 89

2. Single Turns
• Single turn resolution for models with a longer cermet element (larger diameter) is quite respectable. This is especially true with wire brush contacts and smooth cermet films.
• Reference single turn models:
Small diameter - 24, 25, 62, 82
Larger diameter - 72, 91, 93

3. Surface Mount Models
• Single turn - 21, 23, 83
• Multiturn - 44, 84

A trimmer can be used as potentiometer or rheostat. A potentiometer is a three terminal device typically used to vary voltage. In potentiometric configurations, the wiper terminal is lightly loaded so that wiper current is generally small.

A rheostat is a two terminal device typically used to control current. Wiper current is generally larger in rheostat circuits.

I. Types of Applications
The majority of applications for trimmers occur in electronic circuits. 
Typical uses are in the following devices:
A. Amplifiers
B. Timing circuits
C. Voltage and current regulators
D. Voltage and frequency converters
