Fixed inductors are used to store electrical energy in the form of a magnetic field. The ER1025-84JM inductor is a type of fixed inductor that can be used for a variety of applications. This article will explain the field of application and working principle of ER1025-84JM fixed inductors.

Applications

The ER1025-84JM inductors are designed for use in power supply and DC-DC converter circuits. They are also ideal for use in current-sensing applications, telecommunication systems, oscillating circuits, arbitrary waveform generators, switching regulators, overcurrent and overvoltage protection, and ripple filters. The inductors offer high-efficiency performance in a small package and require minimal external circuit components.

The ER1025-84JM can be used in circuits that require voltage levels over 100V. The inductors can operate effectively at temperatures ranging from -55℃ to +125℃. They offer excellent shielding against EMI and RFI interference and are RoHS compliant.

Working Principle

The ER1025-84JM inductors are designed to store energy in the form of a magnetic field when a current passes through them. They consist of a core, made of ferromagnetic material such as iron, that is wrapped in a coil of copper wire. When current passes through the coil, it creates a magnetic field around the core. This magnetic field is what stores the energy in the inductor.

The amount of energy stored in an inductor depends on the inductance, which is measured in henries (H). The ER1025-84JM series has an inductance range of 1µH - 22µH. The amount of power the inductor can handle depends on its saturation current rating, which is the maximum current the inductor can handle without reaching its saturation point, beyond which no additional magnetic field can be generated.

The ER1025-84JM series has a temperature rise rating of 40℃ max. This rating is important to consider when designing a circuit, as the temperature of the inductor must not exceed the rated temperature. The temperature rise rating is also important for specifying inductors in applications involving high-temperature environments.

Conclusion

The ER1025-84JM fixed inductors are designed for use in power supply and DC-DC converter circuits, telecommunication systems, oscillating circuits, arbitrary waveform generators, switching regulators, overcurrent and overvoltage protection, and ripple filters. They offer high-efficiency performance in a small package and require minimal external circuit components. The inductance range is 1µH - 22µH and the temperature rise rating is 40℃ max.
