Bourns 1812 Unshielded Surface Mount Common Mode Choke with Ferrite Core 51 μH Dual Inductors SRF4532

Bourns SRF4532 is a series of 1812 package surface mount common mode chokes featuring a ferrite core, designed to provide 51 μH inductance with dual inductor construction. These chokes are unshielded and optimized for EMI suppression in data and signal lines, including applications in CANbus systems, telecom devices, and consumer electronics.

The SRF4532 inductors support a maximum DC current of 200 mA and offer an inductance tolerance of -30% to +50%. Their compact dimensions - 4.5 mm length, 2.8 mm height, and 3.2 mm depth - allow easy integration on PCBs with space constraints while maintaining high performance at frequencies up to 100 kHz.

Manufactured with a ferrite core material, these common mode chokes provide reliable operation over a broad temperature range from -40°C to 125°C. The maximum DC resistance is 3.5 Ω, and the devices are RoHS compliant, ensuring environmental sustainability and regulatory compliance.

The SRF4532 series is supplied in reel packaging, facilitating automated insertion and efficient production lines.

This product finds industrial use across electronic manufacturing, telecommunications, automotive electronics, and data communication equipment, providing effective interference noise suppression and signal integrity enhancement.
