Power line filter modules are electronic components used to reduce the amount of interference on the power line. The main purpose of a power line filter is to protect connected equipment from power line noise. The ESM-03-221-D is a type of power line filter module.

The ESM-03-221-D has a low profile design and is particularly suitable for applications where a smaller form factor is required. The size of the ESM-03-221-D is only one fourth of the typical power line filter module, making it ideal for applications where space is limited. The module consists of four ceramic capacitors, two inductors, and a metal-oxidized varistor.

The ESM-03-221-D has an operating frequency of 1MHz with a ripple current capability of 250mA. The maximum leakage current is 10mA and the maximum capacitance value is 220nF. The module has an impedance range of 6Ω to 150mΩ. Its rated voltage is 250VAC and its maximum operating temperature is 85°C.

The working principle of the ESM-03-221-D is based on the concept of electromagnetic interference (EMI) suppression. The module contains four ceramic capacitors that are connected to the power line. These capacitors act as a low pass filter and reduce the amount of high frequency signals that are present on the power line. The module also contains two inductors that act as a high pass filter. The inductors block any low frequency signals that may be present on the power line. Finally, the metal-oxidized varistor is used to absorb any remaining noise that may be present on the power line.

The ESM-03-221-D is an excellent power line filter module and is suitable for a wide range of applications including consumer electronics, telecommunications equipment, medical equipment, and industrial applications. Its small size makes it ideal for applications where space is at a premium.

In summary, the ESM-03-221-D is a power line filter module. It has a low profile design and is suitable for applications where space is limited. The module consists of four ceramic capacitors, two inductors, and a metal-oxidized varistor. The working principle of the module is based on the concept of EMI suppression. The module is suitable for a wide range of applications including consumer electronics, telecommunications equipment, medical equipment, and industrial applications.
