Aluminum electrolytic capacitors are an important form of energy storage technology in the entire electronics industry. THA402M040AC1Cs are a specific kind of aluminum electrolytic capacitors. Generally speaking, THA402M040AC1Cs belong to radial leads aluminum electrolytic capacitors, which generally have two types of polar types and non-polar types.

This kind of aluminum electrolytic capacitors are mainly used in the fields of frequency conversion, power switch, high-power inverters, active PFC for air conditioners and motor starting. In normal working conditions, they have a wide range of temperature (-40℃-105℃). Its advantages include high reliability, low internal equivalent series resistance (ESR) and very high damping performance - even under high temperature, its impedance remains stable.

The working principle of THA402M040AC1Cs lies in the capacitance between two electrodes. The capacitor is formed when two metal strips or metal layers are separated by a dielectric material. In an AC circuit, current alternates between the two electrodes, so the capacitor can store electric potential. In a THA402M040AC1C, the two metal strips are usually two sheets of aluminum foil in an anodic oxidation film, and the dielectric material is a gel electrolyte.

When current passes through the THA402M040AC1C, aluminum ions from the electrolyte enter the cathode side surface, forming a deposit. This deposit makes the gap between the two aluminum foils even smaller and its dielectric becomes thicker. As a result, the capacitance of the two aluminum foils increases. Its working process is slow and requires a few hours.

THA402M040AC1Cs can be used in many applications requiring unique temperature and voltage characteristics. Due to its high reliability, versatility and excellent performance, THA402M040AC1Cs capacitors have become an indispensable part of many modern electronic devices. They are suitable for high frequency circuits, where fast start-up and large capacitance are essential for correct operation.
