Fixed Inductors

Inductors, also known as coils, chokes, or reactors, are components that store energy through the creation of a magnetic field when current is applied. Fixed inductors are fixed inductance components with a more stable inductance compared to variable inductors due to their fixed, closed-core design. Fixed inductance chips are manufactured as windings on a magnetic core for mechanical robustness and repeatable performance.

CK21253R3M-T Application Field and Working Principle

The CK21253R3M-T is a fixed inductor manufactured by Kendin Semiconductor. It is typically used in switching power supplies, buck converters, and other power conversion designs. This inductor has an inductance value of 2.7µH, a 10% tolerance, and a maximum current rating of 1.4A.

The CK21253R3M-T works by transforming the energy from an input to a higher or lower output voltage, depending on the application. In a buck converter, for example, the inductor stores energy during its input cycle and releases it through its output cycle. When current enters the inductor, it produces a magnetic field which stores energy and prevents current from leaving in the reverse direction. As the input current decreases, stored energy is released through the output. The inductor plays an important role in determining the switching speed and efficiency of the buck converter.

The CK21253R3M-T fixed inductor has a temperature range of -40 to +105°C, a maximum DC resistance of 0.35Ω, a self-resonant frequency of ≥100MHz, and an typical SRF of ≥118MHz. This chip has high power saturation performance, excellent temperature stability, and low leakage flux, making it a reliable and low-cost solution for many power-related applications.

The CK21253R3M-T fixed inductor is available in an ultra-small SIP package and is designed to meet the requirements of harsh environments including high temperature, humidity, and vibration. The chip has an additional protective coating to ensure superior electrical insulation and environmental protection. This chip is RoHS compliant and is backed by Kendin Semiconductor\'s industry-leading warranty program.

The CK21253R3M-T is an ideal choice for a variety of high-performance, power-related applications, including but not limited to switching power supplies, buck converters, motor controls, battery chargers, and power amplifiers. Its reliable operation and low cost make it a strong choice for designers looking for an efficient power solution.
