Tantalum – Polymer Capacitors are a type of capacitor developed by Elna America Inc. that uses a combination of tantalum and organic material as the dielectric to store electrostatic charge. This type of capacitor is desirable because of its high capacitance and low electrical leakage rates. It has become increasingly popular in many applications where a long lifetime and maximum capacitance are desired. The TCRD476M016R0070J is one example of a tantalum – polymer capacitor.

This capacitor is designed for long-term, reliable operation in ignition circuits where high power spikes are common. The maximum capacitance of the TCRD476M016R0070J is 4.7µF and the full-load ripple current is 16A. It also has an extremely low ESR of 0.7Ω and a tolerance of ±20%. The body has a cylindrical shape and a diameter of 6.3mm (0.25 inches).

Application Field

The TCRD476M016R0070J capacitor is most commonly used in engine ignition circuits for automobiles and engines with rotor ignition systems. It is also used in voltage spike suppression and pass-through fields, among others. It is used to absorb high power spikes, regulate voltage spikes, and provide a charge during engine starts. This capacitor can also be used in areas where a high capacity, long life, and low ESR are required.

Working Principle

Tantalum – Polymer Capacitors are based on a combination of electrostatic charge storage and the polarization of organic material. When a voltage is applied, electric charges are stored on the capacitor body through electric field lines. The dielectric material, composed of tantalum and organic materials, act as the insulator between the electric charges. This capacitance, also referred to as capacitance, is the measure of how much charge can be stored on the capacitor.

When a voltage is applied to the capacitor, the electric charge is stored on the capacitor until equilibrium is reached. This equilibrium is referred to as the capacitance of the capacitor. The maximum capacitance of the TCRD476M016R0070J is 4.7µF. This is the maximum amount of charge that can be stored on the capacitor at any given time.

The ESR, or equivalent series resistance, is also a key factor in the performance of the capacitor. It determines how much current can flow through the capacitor when a voltage is applied to it. The ESR of the TCRD476M016R0070J is 0.7Ω which indicates that it can handle a high amount of current and can effectively absorb high power spikes.

The TCRD476M016R0070J capacitor is a high-capacitance and low-ESR capacitor that is used in many applications to provide reliable, long-term operation. Its capacitance, low ESR, and wide temperature range make it suitable for applications such as engine ignition systems, voltage spike suppression, and pass-through fields.
