Fixed Inductors are an essential type of electrical component, often used to provide an inductance for uses including filtering out high frequency noise and as part of impedance matching circuits. One of the most popular types of fixed inductor is the ER1641-105JM, a high-performance, low profile power inductor from the popular semiconductor manufacturer EPC, incorporated. This article will explore the ER1641-105JM’s application field and working principle.

The ER1641-105JM power inductor is a small, low profile device, designed with a maximum height of only 0.9mm. The inductor is encapsulated in a UL94V-0 grade flame retardant epoxy material, ensuring it can withstand operating temperatures of up to 130° Celsius. Electrical characteristics include an inductance value range of 10uH-100uH and an inductance tolerance of ±20%, making the ER1641-105JM suitable for a variety of application fields.

The ER1641-105JM is suitable for power applications such as DC-DC switching regulators, telecoms power supplies, automotive systems, and audio amplifiers. The device’s low profile design allows it to be easily integrated within confined spaces such as small printed circuit boards (PCBs).

The ER1641-105JM is constructed of slits in the core and copper coil winding. The alternating current that appears on the inductor in the case of a DC-DC conversion passes through the copper coil winding. This produces an opposing magnetic field which opposes the change in current flow, maintaining inductance.

The ER1641-105JM’s copper coil windings provide an efficient, low profile RF shielding, making it an ideal device for audio power amplifiers and RF applications. The device is also able to sustain performance at frequencies in excess of 1MHz, making it suitable for a wide range of high-frequency applications.

The ER1641-105JM is one of the most popular power inductors due to its low profile design, high performance and reliable operation. Its wide range of application fields makes it an ideal device for a variety of circuit designs.
