(1)It is recommended that capacitors should be used at a voltage less than the rated voltage.
It is also recommended to properly derate the voltage to improve operating reliability. 

(2)Customers in the product installation to avoid the occurrence of individual products locally over temperature conditions (≥260 ℃), and to avoid direct contact with high temperature soldering paste tantalum capacitor body.

(3) In low impedance circuit applications such as power supply circuits, the failure rate may increase due to inrush current.
Additionally, if a short occurs within the capacitor, burning may possibly occur.
Therefore, sufficient voltage derating is recommended. Use voltage should be within 30% -50% of the rated voltage, thereby improving the reliability of the circuit, in order to avoid the adverse effects of inrush current.

Appreciate your greetings during our Chinese Spring Festival. May the new year brings you good fortune as well.

We keep contributing to your electronic component demands in 2016. Our components are ISO/ SGS/ RoHS/ UL/ Reach certified. Meanwhile, free samples are available once needed. Below pls check our sample stock. Hope you share more business and we return you the better support. ^ o ^

Kingtronics offers full range of Trimming Potentiometers with our own trademark "Kt" since 1990.
We gain high reputation by our trimpots superior quality and competitive price. We are proud that Kingtronics Trimpot are well-known in the overseas market.

In Jan 2016, we prepared all the key raw materials of Trimming Potentiometers and then handed over to SGS laboratory.
After 1 week testing , we got the positive reply of our potentiometers from SGS company.  Now we would like to share this good news with our Kingtronics faithful customer.
Kingtronics Trimming Potentiometer is your first chosie, and Kingtronics is your best partner.

Dear Friends,

Need our price for any components? trimpot, capacitor, diode, crystal... We own two factories producing various components. Pls ask for better support without hesitation. Let's lose no time and seize more business together. 

Pls note we will begin our Chinese Spring Festival holiday soon. We suggest you place orders in advance, and we could arrange pre-production process accordingly. Kindly contact our sales for relevant issues in this period. Sorry for the possible inconvenience!

ROTATIONAL LIFE:
The number of cycles obtainable under specific operating conditions while remaining within specified allowable degradation. A cycle is defined as one complete traversal of the wiper over the resistive element in both directions.

LOAD LIFE:
The number of hours at which a device may dissipate rated power under specified operating conditions while remaining within specified allowable degradations.

ADJUSTABILITY:
Defines the precision with which the output of a device can be set to the desired value.

ADJUSTABILITY (OUTPUT RESISTANCE):
The precision with which the output resistance of a device can be set to the desired value.

ADJUSTABILITY (OUTPUT VOLTAGE RATIO):
The precision with which the output voltage ratio of a device can be set to the desired value.

Dear clients, wish you enjoy a nice weekend with your families. ^_^

We cooperated with Setron from 2014, and it mergered with Arrow Electronics last year. Now we directly work with Arrow. Cheers!

Hope this can make you know more about us and share with us your precious business chance. We sincerely hope to become your strong backup force in your path to success.

Capacitor, Trimming potentiometer, Quartz crystal, Diode rectifier, Bridge rectifier, 
Transistor, Surge arrester

CONTINUITY:
Continuity is the maintenance of continuous electrical contact between the wiper and both end terminals of the resistive element.

SETTING STABILITY:
The amount of change in the output voltage, without readjustment, expressed as a percentage of the total applied voltage.

DIELECTRIC STRENGTH:
The ability to withstand the application of a specified potential of a given characteristic, between the terminals and all other external conducting member such as shaft, housing and mounting hardware without exceeding a specified leakage current value.

INSULATION RESISTANCE:
The resistance to a specified dc voltage impressed between the terminals and all other external conducting members such as shaft, housing and mounting hardware.

POWER RATING:
The maximum power that a trimming potentiometer can dissipate across the total resistive element under specified conditions while meeting specified performance requirements.

We will have a CNY holiday soon, but we have specially prepared below stock for you. Don't worry about the lead time during this period.

Pls feel free to conatct us even in CNY holiday. Our sales office will be only closed from 6th Feb to 10th Feb.

CONTACT RESISTANCE VARIATION: (CRV)
The apparent resistance seen between the wiper and the resistance element when the wiper is energized with a specified current and moved over the adjustment travel in either direction at a constant speed. The output variations are measured over a specified frequency bandwidth, exclusive of the effects due to roll-on or roll-off of the terminations and is expressed in ohms or % of Rt.

EQUIVALENT NOISE RESISTANCE: (ENR)
(Wirewound only) Any spurious variation in the electrical output not present in the input, defined quantitatively in terms of an equivalent parasitic, transient resistance in ohms, appearing between the contact and the resistive element when the shaft is rotated or translated. The Equivalent Noise Resistance is defined independently of the resolution, functional characteristics and the total travel. The magnitude of the Equivalent Noise Resistance is the maximum departure from a specific reference line. The wiper of the potentiometer is required to be excited by a specific current and moved at a specific speed.

Happy New Year. Wish dear all good luck and good health in whole 2016.
