Chinese Lunar New Year is approaching in next month.
Kingtronics sales offices will have holiday during 12th ~15th February.
But from early February, our production lines will have 2-3 weeks holiday.
The lead time will be extended accordingly.

Meanwhile, material supplies is unstable in the market recently which also leads to longer lead time.
If there is any order plan, please feel free to confirm earlier to fight for better delivery dates.

Historically, Tantalum capacitors have been used for smoothing and decoupling applications for switching power supplies, DC/DC converters, LCD drivers and general digital circuits. As the need grew for efficient power converters that operate at high frequencies, the design engineer needed components that dissipated less heat. For high frequency applications‚ chip capacitor is an excellent substitute for a Tantalum capacitor. Compared to a Tantalum capacitor‚ chip capacitor has a low ESR and low ESL at high frequencies. As a result, selecting a Tanceram‚ capacitor with 1/2 to 1/10th the capacitance of a Tantalum will produce an impedance that is more than an order of magnitude lower than the Tantalum capacitor over the same high frequency range. The following example will compare the performance.

From 100 KHz to 70 MHz the typical 4.7µF, chip capacitor has a measured ESR from .05 to .02 Ohms while a typical 10µF Tantalum capacitor ESR measures from 1.2 to 0.8 Ohms. In this example‚ chip capacitor has a typical ESR that is 4% of the value of a comparable Tantalum capacitor over the frequency range of 100 KHz to 70 MHz. (See Figure 1.)

A typical 4.7uF Tanceram‚ chip capacitor has low impedance from 100 KHz to 70 MHz. From Figure 2 the self-resonant frequency is approximately 3 MHz, for a remarkably low ESL of 600pH! Also, the lower impedance produces less heat in power conversion applications. Figure 3 shows the temperature rise vs. ripple current. From the example capacitor values‚ chip capacitor can handle approximately 3 times the ripple current to produce a comparable temperature rise.

Often, substituting a Tanceram‚ chip capacitor to replace a Tantalum capacitor will reduce the circuit size and cost while providing superior performance. 

The equivalent series resistance (ESR) of a solid tantalum capacitor is frequency dependent. The curves of Figure 6 are typical of the capacitor values noted, with measurements being made by contacting lead wires 1/4 inch from the ends of the capacitor cases. Since ESR decreases with frequency, AC performance at higher frequencies is considerably better than would be predicted from the 120 Hz ratings.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
