There are many factors that need to be considered when selecting capacitors. The following discusses the capacitor selection elements of MLCC.

MLCC selection: Just meeting the parameters is not enough.
The general decision-making logic for purchasing a product is: whether it can be used, whether it is easy to use, whether it is durable, and the price. In fact, this logic can also be applied to the selection process of MLCC: firstly, the MLCC parameters must meet the circuit requirements, and secondly, whether the parameters and media can make the system work in the optimal state; Besides, is there any defective product in the incoming MLCC and how reliable is it; Finally, is there an advantage in price and is the supplier's cooperation timely. Many design engineers do not attach importance to passive components, thinking that only theoretical calculation of parameters is sufficient. In fact, the selection of MLCC is a complex process, and it is not simply satisfying the parameters.

Selection Elements
-Parameters: capacitance value, tolerance, withstand voltage, operating temperature, size
-Material
-DC bias effect
-Failure
-Price and Supply

The performance of different media determines the different applications of MLCC
-C0G capacitors have high temperature compensation characteristics and are suitable for use as bypass capacitors and coupling capacitors
-The X7R capacitor is a temperature stable ceramic capacitor, suitable for industrial applications with low requirements
-The Z5U capacitor is characterized by its small size and low cost, making it particularly suitable for application in decoupling circuits
-Y5V capacitor has the worst temperature characteristic, but its capacity is large, which can replace the low capacitance Aluminum electrolytic capacitor

MLCC commonly uses different media specifications such as C0G (NP0), X7R, Z5U, Y5V, etc. Different specifications have different characteristics and applications. The main difference between C0G, X7R, Z5U, and Y5V is their different filling media. Under the same volume, the capacity of capacitors composed of different filling media varies, resulting in different dielectric losses and capacity stability. Therefore, when using capacitors, different capacitors should be selected based on their different functions in the circuit.

Since MuRata has stopped offering Ceramic Trimmer Capacitor TZC3 series, lots of supplies are looking for the replacement with competitive quality and price.
Kingtronics KKT series could be your best support of making replacement with excellent performance and efficient lead time.

We have stock offer in HK, welcome check following cross reference and share your inquiry with us, let us help you to save your cost.

SMD 3mm Chip Ceramic Trimmer Capacitor features:
Low capacitance drift
High durability from vibration, dust, moisture and flux
Color coded case permits easy identification
Very good Q and high resonant frequency
Designed for reflow soldering.
Small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm

Since Murata stopped making trimmer capacitors, many customers turned to us to find a replacement.

Kingtronics’ Ceramic Trimmer Capacitors definitely can help you solve this problem. Our KKT series can cross to most of Murata Trimmer Capacitor.

Hot stock available. Welcome to contact our sales to give you best support.

Kingtronics corresponds to Murata products as follows:

Any order plan scheduled in early October ?

Please note early Oct. our production team will have one week holiday for National Day.

Our production line is tight and fully arranged, so that if order in early Oct. lead time might postpone 2-3 weeks later.

It will be wiser if possible confirm order before end Sept. to have more chances reach better lead time.

Meanwhile, we have hot stock for Diode LL4148, M7, SMD 3mm trimmer capacitor now !

Please don’t hesitate to contact us, we’re willing to support !

MuRata will stop offer trimmer capacitors after 2021 March, maybe it is not a good new for some customer who support product by MuRata. Some product of TZY2 series, which is small and thin size with external dimensions of 2.5(W) x3.2 (L) x1.25max(H)mm, have been discontinued (remark:red). Blue-label products will be discontinued as below.

If you change your PCB pattern size, Kingtronics KKT series suit for you, which is small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm. New shape of cover can improve the adhesion between rotor and stator leads to superior stability. It is suitable for high frequency circuit due to high self-resonant frequency. We can be your best support for KKT series with regular stock, competitive price, RoHS qualification, few samples!

It designed for reflow soldering and application for crystal oscillators, crystal filters, radar detectors, stylus pen, compact radios, hand radios, burglarproof devices, headphone stereos, and remote keyless entry systems

 Dear valued customers, 

Please try to focus on our radila MLCC(multilayer ceramic capacitor) business if you have demands of MLCC, currently we stop accepting order of SMD MLCC, the main reason is there're too many orders on production, thus we are unable to supply new demands, kindly try to understand and support us. 

MLCC out of stock is a globally situation, mainly results from some famous manufacturers discontinued the standard mlcc, supply structures get adjustments, market demands get increasing.

We are still supplying radial, axial MLCC, L/T is 3-5weeks or shorter, and price is always competitive. Never hesitate to enjoy our considerate support., contact with our sales now.
