B82422A3821K100 Description

Short technical summary and product information.

The B82422A3821K100 is a wirewound RF inductor from TDK's B82422A series. It offers an inductance of 820nH with a tolerance of ±10%. The component is rated for a maximum DC current of 140mA and has a maximum DC resistance of 2.5 Ohms. It features a minimum Q factor of 22 at 30MHz and a self-resonant frequency of 240MHz, making it suitable for RF applications up to VHF ranges.

 

Constructed with a ceramic core and unshielded wirewound design, the inductor provides stable performance. It is qualified to AEC-Q200 automotive standard, ensuring reliability under harsh conditions. The part operates over a temperature range of -55°C to +125°C (manufacturer page indicates up to +145°C).

 

The inductor is packaged in a 1210 (3225 Metric) case size, with J-Lead terminations for surface mounting. It is available in reel and cut tape packaging. The dimensions are 3.20mm length, 2.50mm width, and 2.10mm height. This component is suitable for DC-DC converters, RF filtering, and automotive electronics where space and performance are critical.
