Fixed inductors are electronic components used in virtually every electrical, automotive, and industrial device. An inductor is a device that stores energy in the form of an electromagnetic field and uses it to limit current and voltage levels, or to provide reactance. The ETQ-A17B100 is a fixed inductor manufactured by TDK Electronics Co., Ltd., and is typically used in power supplies, switching power supplies, and automotive electrical equipment.

ETQ-A17B100 Description

The ETQ-A17B100 is a surface-mount inductor, measuring 6.2 mm x 3.2 mm x 3.6 mm (L x W x H). It offers low DC resistance and is an ideal choice for noise suppression and power supplies. The inductance of the ETQ-A17B100 is 100 uH ±20% at an operating frequency of 400 kHz. It has a rated current of approximately 4.31 A, with a saturation current of 4.85 A. As a critically important safety feature, the inductor has an insulation level of 2000 V rms for one minute duration.

ETQ-A17B100 Application Field and Working Principle

The ETQ-A17B100 fixed inductor is widely used in DC-DC converter circuits, low-noise designs, and switched mode power supply (SMPS) circuits that require high switching power and low output ripple current. It is designed for 3 V and 5 V power supplies, and also offers excellent ambient noise immunity in high-current power supply systems. The inductor is also used in automotive power supply circuits and the general electronics industry.

The ETQ-A17B100 is used to limit the current flow in a circuit, where too much current could potentially cause damage. It works on the principle of inductance, which is the ability of an electric current to create an electromagnetic field. When current passes through the inductor, a magnetic field is created which stores energy in the form of an electromagnetic field. This field induces a voltage, proportional to the rate of change of the current, that opposes the flow of the current, and thus limits the amount of current.

Conclusion

The ETQ-A17B100 fixed inductor from TDK Electronics Co., Ltd. is a versatile component, designed for use in a variety of applications related to power supply and noise suppression. It offers high operational frequency, low DC resistance, and is able to withstand high current with a maximum saturation current of 4.85 A. The device has a range of applications it is designed for, including automotive power supplies, DC-DC converters, and low-noise designs.
