Fixed Inductors

1210R-123H application field and working principle

Fixed inductors are passive electronic components that typically contain a coil of wire wrapped around a core material. Low-frequency fixed inductors are made of non-magnetic materials such as plastic or air. When current passes through an inductor, a magnetic field is generated, and this field stores energy in the form of induction.The 1210R-123H is a high-frequency fixed inductor designed for applications in Audio and RF circuits. It is a general-purpose type of inductor. The 1210R-123H can withstand both high current and high frequency. The standard inductance range is 10 to 75 uH.The core of the 1210R-123H is made of high-frequency magnetic materials such as ferrite or powdered iron. This core material helps to increase the performance of the inductor, providing enhanced inductance at high frequencies. The coil is made of copper wire, which has high conductivity and is less susceptible to displacement.The working principle of the 1210R-123H is based on Lenz’s Law. When a varying current is passed through the fixed inductor, an electromagnetic field is generated inside the device due to the changing current and the core material. This electromagnetic field opposes the change of current, and a counter EMF is produced. This EMF tends to oppose the current that is causing it, and this creates a voltage drop across the inductor.This voltage drop is called inductive reactance, and it can be used to reduce the current flowing though the inductor. This is beneficial in applications such as audio or RF signal conditioning, power supplies and motor control, where current needs to be reduced in order to reduce power consumption or prevent electric shock.The 1210R-123H is a fixed inductor that is versatile and can be used in a variety of applications such as audio or RF filtering, transformer coupling, transformer-less AC power supplies, and more. It is a reliable, versatile component that is designed to last. It is a low-cost, high-performance component that is one of the most popular inductors in use today.
