B82720S2102N040 Description

Short technical summary and product information.

The TDK B82720S2102N040 is a current-compensated SMD ring core double choke from the B82720S series. It offers a nominal inductance of 3mH at 10 kHz, a rated current of 1A at +40°C, and a rated voltage of 250V AC. The choke features a ferrite core with epoxy coating and a plastic case, both UL 94 V-0 rated, and sector winding construction.

 

Designed for surface mount assembly, this component is supplied in a horizontal 8-gull-wing package measuring 14.50mm x 13.30mm with a maximum height of 10.70mm and weighs 2.5g. It includes approximately 0.7% stray inductance for differential-mode interference suppression and is suitable for reflow soldering.

 

Typical applications include suppression of common-mode interferences in compact electronic ballasts for lamps and compact switch-mode power supplies. The operating temperature range is -40°C to +125°C with a rated temperature of +40°C.
