Kingtronics Tantalum Capacitors Cross Reference

Kingtronics produces 2 kinds of electrolytic capacitors:  Aluminum electrolytic capacitor and Tantalum capacitor. 

Application:

Aluminum Electrolytic Capacitor: automotive power, industrial LED lighting, telecom infrastructure, power supplies,input and output smoothing, audio amplifiers, motor start, blocking and dc-bypass circuits, photoflash and strobe...

Tantalum Capacitor: portable telephones, pagers, personal computers, and automotive electronics, traffic light, washing machine, electronic security, shortwave radio transmitters and receivers, remote controls, power supply, reader module

Guidance:

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.
