BLM31SN500SN1L Description

Short technical summary and product information.

The Murata BLM31SN500SN1L is a chip ferrite bead designed for power line applications in consumer, industrial, and medical equipment. It provides 50 Ohm impedance at 100 MHz to suppress high-frequency noise on power supply lines.

 

This ferrite bead is rated for a maximum DC current of 12A at 85°C ambient, with derating to 10A at 125°C. The maximum DC resistance is 1.6 mOhm, minimizing power loss in high-current circuits. It operates over a temperature range of -55°C to +125°C.

 

The component is housed in a standard 1206 (3216 Metric) surface mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. It is a single-line device suitable for automated assembly.
