Fixed inductors are passive electronic components that are used to store energy in the form of magnetic fields. The most common type of fixed inductor is the HCm1A1305-220-R. This particular type is typically used to integrate multiple power supply voltages for microprocessor and logic applications.

It is composed of two major components – the core, which is typically made of iron, and the wire-wound coil, which is usually made from copper. This particular device measures 8mm in length and is 2.5mm in diameter. The core material has a permeability of either 79 or 140, and the wire-wound coil has a resistance rating of 220 ohms.

When the HCm1A1305-220-R fixed inductor is connected to a DC voltage source, a current flows into the device. This current creates a magnetic field in the core, which is proportional to the magnitude of the current. The magnetic field induces an electromotive force (EMF) in the coil, which causes a second current to circulate through the coil. This second current opposes the first, causing a voltage drop across the coil, which is proportional to the initial current.

The HCm1A1305-220-R has many applications, including providing isolated power supply voltages in the following devices: microprocessors, motherboards, power supply regulators, digital signal processors, and sensor measurement systems. It can also be used to reduce electromagnetic interference (EMI) in switch mode power supplies.

In addition, the HCm1A1305-220-R can be used to filter high frequency signals, as it creates a high impedance path within the cores and windings of the inductor. This in turn reduces the amount of RF and other high-frequency signals that can be coupled into and out of the circuit. It can also provide a path for common-mode currents, or high frequencies, to be diverted away from the delicate components of the system.

The HCm1A1305-220-R fixed inductor has many advantages, including low resistance, low stray inductance, extremely stable performance, and low core losses. It is a reliable and cost-effective choice for many applications, and is sure to be a reliable part for any type of power system design.
