In second half of 2018, we met tough challenge with SOT-23 package diodes and transistors raw material supplies.
The prices increased and lead time was much longer than ever before.

Fortunately, SOT-23 package support is resumed normal in late Jan, 2019.
We even have chance to offer better prices than the original ones for some values with big quantity now.

Welcome to share request to check our latest support !

Ceramic Trimmer capacitors are variable capacitors. They are mounted directly on the PCB board with a provision to vary their value using a small screwdriver.The trimmer capacitors are serving the purpose of initial calibration of equipment during manufacturing or servicing and are not meant to be varied by the end user. It is used to remote keyless entry system, measuring instrument, security system and wireless microphone.

Murata Ceramic Trimmer Capacitors TZB4 and TZC3 series to be discontinued in 2019. As a competitor, Kingtronics KKT series can replace Murata TZC3 series. If you are looking for a TZB4 series ,we recommend that you change the devices size to fit KKT series because of there is no direct replacrment product in competitors.

Kingtronics KKT SMD 3mm Chip Ceramic Trimmer Capacitor Features:
1)Small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm.
2) Color coded case permits easy identification.
3) Heat resistant resin withstands reflow soldering temperatures.
4）Bulk and reel packaging are available.
Kingtronics corresponds to Murata products as follows:

As you know every year approaching the Christmas season will get busy with factories, so does Chinese New Year time.

The coming Chinese New Year also known as Lunar New Year or Spring Festival.
This is a time for family reunion, and is considered the most important part in the Chinese New Year celebration.

In 2019, the festivity will be on 5th-7th Feb., our factory will have holidays from late January till mid-February.
The production lead time might be longer once place order within or after CNY.

Thus please don’t hesitate to advise us the order confirmation soon, and arrange production without delay. : )

Good day !

A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
A、因為電解電容的容量較一般固定電容大得多，所以，測量時，應針對不同容量選用合適的量程。一般情況下，1～47μF間的電容，可用R×1k擋測量，大於47μF的電容可用R×100擋測量。

B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is  the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
B、將萬用表紅表筆接負極，黑表筆接正極，在剛接觸的瞬間，萬用表指針即向右偏轉較大偏度(對於同一電阻擋，容量越大，擺幅越大)，接着逐漸向左迴轉，直到停在某一位置。此時的阻值便是電解電容的正向漏電阻，此值略大於反向漏電阻。電解電容的漏電阻一般應在幾百kΩ以上，否則，將不能正常工作。在測試中，若正向、反向均無充電的現象，即錶針不動，則說明容量消失或內部斷路;如果所測阻值很小或為零，說明電容漏電大或已擊穿損壞，不能再使用。

C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
C、對於正、負極標誌不明的電解電容器，可利用上述測量漏電阻的方法加以判別。即先任意測一下漏電阻，記住其大小，然後交換表筆再測出一個阻值。兩次測量中阻值大的那一次便是正向接法，即黑表筆接的是正極，紅表筆接的是負極。

D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.
D、使用萬用表電阻擋，採用給電解電容進行正、反向充電的方法，根據指針向右擺動幅度的大小，可估測出電解電容的容量。

What leads Thermistors to failure mode (short circuit mode and open-circuit mode)?
The reason why substrate burn-down and blow off occurred while turning on devices, subjected to low temperature of sintering, ceramic isn’t firing mature, as well as mechanical stressed, causing larger current than the ripple current can tolerate, etc …

Solutions:
1) Sintering at the right temperature.
2) Reduce defects
3) Avoid large current
4) Only use high purity, and good raw materials

The demand for Negative Temperature Coefficient Thermistor has been increased these years in automotive industry, for the use of powertrain, safety and controls, as well as in alternative of fuel vehicles, since the awareness of eco-friendly has arouse.

Thermistors are growing steady in the market at the moment.
And also, the research has shown that this trend will keep following up in the upcoming years.
