BLM21PG300SN1D Description

Short technical summary and product information.

The Murata BLM21PG300SN1D is a chip ferrite bead designed for power line filtering in consumer, industrial, and medical equipment. It offers a nominal impedance of 30 Ω at 100 MHz with ±10% tolerance. The component is rated for a maximum DC current of 4 A at 85°C ambient and 2.3 A at 125°C, with a maximum DC resistance of 14 mΩ. Housed in a standard 0805 (2012 metric) surface-mount package, it measures 2.00 mm x 1.25 mm with a maximum height of 1.05 mm. The operating temperature range spans -55°C to 125°C. This ferrite bead is supplied on tape and reel with a standard reel quantity of 3000 pieces.
