Common Mode Chokes, like the TCM0403R-900-2P-T210, can be used to reduce both conducted and radiated noise on circuits that use voltages from 24V to 277V AC. It can be used in a wide range of applications, such as mains filter, line filter, and low-frequency converters. Common Mode Chokes offer a number of benefits, including improved noise immunity, reduced system EMC, and a stable system DC voltage.

This model of Common Mode Choke is designed to reduce common-mode noise, which is signal noise that travels in both directions along a shared line or a twisted pair of wires. It uses a ferrite core to convert alternating currents (AC) to direct current (DC), reducing the frequency of the noise. The choke also has wound conductors wrapped around the core, which reject interference coupled from external sources.

To understand how a Common Mode Choke works, consider its two outputs: common-mode output and differential-mode output. The common-mode output, usually two wires side-by-side, is used to reject external interference, while the differential-mode output eliminates the noise generated by circuits connected to the choke. When the mixture of the two outputs passes through the ferrite core and the wound conductors, the interference is blocked, allowing only signals that meet the desired AC voltage to flow through to the output.

The TCM0403R-900-2P-T210 Common Mode Choke has an operating temperature of 40°C to 70°C and a leakage current range of 0.1mA to 0.5mA. It also has a peak current rating of 6A, a DC resistance of 12.5 ohms, and an inductance of 900mH. The device is designed to operate in both single- and three-phase AC systems with a power factor up to 0.99.

Common Mode Chokes are useful for reducing both conducted and radiated interference in AC power circuit applications. By converting energy from AC to DC, the device provides isolation from the noise generated by AC signals, shield sensitive electronics, and reduce power consumption. The TCM0403R-900-2P-T210 model is ideal for a variety of application scenarios, especially in mains filters, line filters, and low-frequency converters.
