Fixed Inductors

Fixed inductors, commonly referred to as chokes, are electrical components used to store energy in a circuit. They are frequently used in filtering applications, as the component of an RLC circuit, and even as oscillator circuits. Fixed inductors are manufactured in several different core materials, including ferrite and powdered iron, as well as several coil forms that are designed for various applications.

2474-29K Application Field and Working Principle

The 2474-29K fixed inductor is an axial-lead type design with low-cost and good stability. It\'s designed to be used in analog power electronic devices, power supplies, transformers, amplifiers and other high-frequency circuits. This type of inductor has a rated current of 1.3 A and an inductance of 29µH.

The 2474-29K fixed inductor is designed primarily for functions in power supplies, output filters and output voltage regulation. In addition, it can be used to deliver high power and to provide a constant, low inductive resistance inductor for high current loads. The core material is molded from a combination of ferrite and powdered iron, which provides high electrical insulation for higher current requirements.

The 2474-29K fixed inductor has an axial single-lead construction, a high-temperature insulation coating and double-layer insulation for stable operation. It has a molded plastic coating that protects the threaded portion, which increases its insulation resistance by up to 1x10^7 Ohms, against leakage or sparks due to contact with other components.

The working principle of the 2474-29K fixed inductor is based on Faraday\'s Law of Induction. The current being supplied to the inductor generates a magnetic field which induces a voltage in the inductor in the opposite direction to the current. This voltage is also known as a back-EMF and opposes the input current, thus limiting the current in the circuit. The strength of the back-EMF increases with the amount of current flowing through the inductor, up to a certain point, beyond which the resistance and inductance of the inductor limit the current.

The 2474-29K fixed inductor is a reliable and low-cost component that can be used to filter noise and reduce interference, safeguard against short-circuits, and protect sensitive devices. It is also used in transformer and audio applications, as well as in switching power supplies. The inductor\'s construction, materials and core inductance make it a reliable and cost-effective choice for many RF and power applications.
