Product Description

TDK B82789C0513N002 is an unshielded surface mount common mode choke housed in an 1812 package with a Ferrite Core delivering an inductance of 51 μH and an inductance tolerance of -30 to 50%. It is a wirewound inductor using a bifilar winding design that effectively suppresses asymmetric electromagnetic interference (EMI). The choke supports a maximum direct current of 250 mA and exhibits a maximum DC resistance of 550 mΩ, ensuring efficient filtering in sensitive electronic circuits.

This component operates over a broad temperature range from -55°C to 125°C, making it suitable for harsh environmental conditions often encountered in automotive and industrial applications. The choke is in a flame retardant moulded case compliant with UL 94 V-0, featuring lead-free tinned solder terminals to meet environmental regulations such as RoHS.

Its compact dimensions - 5.2 mm in length, 3 mm in height, and 3.2 mm in depth - allow for high-density PCB layouts, enhancing the miniaturization of electronic devices. The tape-packaged surface mount device (SMD) format facilitates automated assembly processes, improving production efficiency.

Common applications for the B82789 series include automotive communication buses (e.g., CAN bus), industrial automation control systems, and telecommunications equipment, where EMI suppression and signal integrity are critical.

The product is a bifilar wound choke designed for asymmetric interference suppression. Meets automotive standard AEC-Q200 for quality and reliability. Flame retardant case and lead-free terminals reinforce safety and compliance.

Broad operating temperature range ensures functionality in demanding conditions. Compact 1812 package size optimizes PCB space. Tape packaging supports efficient surface mount assembly. Suitable for automotive, industrial, and telecommunications electronics applications.

This TDK common mode choke is a reliable choice for engineers seeking efficient noise suppression in compact surface mount form factors. Explore related products and solutions in the Surface Mount Inductors category at EnvMart for comprehensive design needs and high-quality components.
