Fixed inductors are one of the most common and basic components used in the circuit boards of a wide variety of electronic and electrical equipment. The PM74SH-181M-RC fixed inductor is designed to be used in devices that require high current and high inductance.

This inductor has a maximum DC current of up to 160mA, a maximum inductance of up to 1.8uH, and a low self-resonance frequency of up to 3MHz. It is also compact and lightweight, with dimensions of 3.2mm x 2.1mm, a thickness of 1.6mm, and a weight of just 0.26g.

The PM74SH-181M-RC is used in a variety of electrical and electronic equipment, including cell phones and other mobile devices, power inverters, radio receivers, and medical equipment. It can also be used for power line frequency detection circuits, voltage control circuits, pulse filter circuits, and frequency divider circuits.

The working principle of a PM74SH-181M-RC fixed inductor is relatively simple. When an AC or DC signal is applied to the inductor, a magnetic field is generated around it. This magnetic field then induces a current in the inductor, which is then proportional to the applied current or voltage.

The magnetic field is established by the number and arrangement of wire turns in the inductor, and its inductance is given by the radical of the wire turn ratio, material permeability, and the product of wire area and length. Additionally, the current induced in the inductor is dependent on the applied frequency and the frequency content of the waveform.

The PM74SH-181M-RC inductor has several advantages over other types of fixed inductors. It has a wide operating temperature range, from -40°C to 85°C, and it has a higher frequency range than other similar-sized devices. Additionally, its low self-resonance frequency helps to ensure constant inductance across a wide frequency range.

Overall, the PM74SH-181M-RC fixed inductor is a versatile and cost-effective solution for uses in a wide variety of electrical and electronic equipment. Its high current capability, compact size, and high inductance make it an ideal choice when designing a circuit board for a variety of applications.
