Multicomp Pro Axial RF Choke AL Series, 22 µH, 410 mA

The Multicomp Pro Axial RF Choke AL Series is a high-quality, axial-lead inductor engineered for robust performance in radio frequency (RF) and power supply applications. With a rated inductance of 22 µH and a DC current rating of 410 mA, this choke is designed to filter out unwanted high-frequency noise and interference, ensuring cleaner and more stable electronic signals.

Constructed for reliability, it features a low DC resistance of just 0.84 ohm, which minimises power loss and heat generation under normal operating conditions. The component has a broad self-resonant frequency of 9.9 MHz, making it highly effective within its specified frequency range. The ± 10% inductance tolerance provides consistent performance across production batches, which is essential for predictable circuit behaviour in both prototyping and volume manufacturing.

Its compact, axial-lead design allows for straightforward through-hole PCB mounting, facilitating easy integration into a wide array of electronic assemblies. The durable build ensures long-term stability and performance in demanding environments.

Key Applications

This RF choke is ideal for use in power supply filtering, DC-DC converters, and RF circuit designs where suppressing electromagnetic interference (EMI) is critical. It is commonly employed in telecommunications equipment, audio devices, and various consumer electronics to enhance signal integrity and overall system performance.
