CM453232-3R3KL Description

Short technical summary and product information.

The Bourns CM453232-3R3KL is a fixed inductor featuring a ferrite core with unshielded wirewound construction. It offers an inductance of 3.3 µH with ±10% tolerance, a current rating of 355 mA, and a maximum DC resistance of 800 mOhm. The component exhibits a typical Q factor of 50 at 7.96 MHz and a self-resonant frequency of 45 MHz, making it suitable for RF and filtering applications.

 

The inductor is housed in a 1812 (4532 Metric) surface mount package with dimensions of 4.50 mm x 3.20 mm x 3.40 mm. It operates over a temperature range of -40°C to +125°C. The part is listed as RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited), though these compliance claims are unverified.

 

This component is designed for automatic surface mounting and is available in various packaging options including Tape & Reel, Cut Tape, and Digi-Reel through distributors. It is commonly used in general purpose inductance applications where moderate current and high Q are required.
