TDK 1812 Unshielded Surface Mount Common Mode Choke with Ferrite Core 51 μH -30 to 50 % Inductance, 200 mA B82787C0513H002

TDK B82787C0513H002 is an 1812 unshielded surface mount common mode choke featuring a ferrite core and wirewound inductor construction. It provides an inductance of 51 μH with a tolerance of -30 to 50 % and a maximum DC current rating of 200 mA. This choke is engineered for automotive CAN bus system applications and other signal line environments requiring common mode noise suppression.

The component operates reliably within a temperature range from -40°C to 150°C. Its compact surface mount 1812 package measures 4.5 mm in length, 2.8 mm in height, and 3.2 mm in depth, enabling dense PCB layouts. With no shielding, it relies on the ferrite core to provide effective common mode noise attenuation while maintaining a maximum DC resistance of 1 Ω. The maximum self-resonant frequency is rated at 10 MHz.

Manufactured to comply with RoHS directives and qualified to the stringent automotive standard AEC-Q200, this component supports lead-free reflow soldering processes. It comes supplied on reel packaging facilitating efficient automated pick-and-place assembly.

Applications include automotive signal bus lines and data signal conditioning, where compact size and noise reduction are critical. Its wirewound ferrite core design ensures stable inductance over temperature and current load conditions.
