Fixed Inductors

A fixed inductor is an electrical device used to store energy in a magnetic field. It is also known as a passive component because it does not require any input power to operate. Fixed inductors are used in many applications such as radio frequency (RF) and power filters, chokes and balanced transmission lines. The basic design of a fixed inductor includes a core, a winding, and a housing.

SRE6603-1R0M application field and working principle

The SRE6603-1R0M is an axial-leaded, fixed inductor that can be used for various RF and power applications, such as RF filters, chokes, balanced transmission lines, etc. The SRE6603-1R0M is designed with an axial-leaded constructional core and a winding coil.

The SRE6603-1R0M inductor has a wide operating frequency range, with a typical Resonant Frequency (f0) of 50MHz and a -3dB point (f12dB) of 100MHz. It is designed to work within the frequency range of 1MHz – 10GHz and can be used in a variety of applications including low-noise amplifiers (LNAs), antenna impedance matching and power factor correction (PFC).

In general,when the frequency of the current passing through the fixed inductor is higher than the resonant frequency, the inductance of the fixed inductor increases and decreases with it. When the frequency of the current is lower than the resonant frequency, the inductance of the fixed inductor decreases and increases. This is known as the resonance frequency and is the main working principle of the fixed inductor.

The SRE6603-1R0M inductor is constructed of high-temperature annealed copper wire and is designed to have low losses at high frequencies. It has a self-resonant frequency of 50MHz and a maximum DC current rating of 1A. The operating ambient temperature range is -55°C to 125°C.
