BLM31SN500SZ1L Description

Short technical summary and product information.

The Murata BLM31SN500SZ1L is a chip ferrite bead designed for power line filtering in automotive electronics. It provides a nominal impedance of 50 Ω at 100 MHz with a tolerance of ±25%, and is rated for a maximum DC resistance of 1.6 mΩ initially, increasing to 2.1 mΩ after AEC-Q200 stress testing.

 

This ferrite bead supports a rated current of 12 A at 85°C ambient and 10 A at 125°C ambient, with derating applied based on operating temperature. It operates over a temperature range of -55°C to +125°C and is qualified to AEC-Q200, making it suitable for demanding automotive environments.

 

The component is housed in a 1206 (3216 Metric) surface-mount package with dimensions of 3.20 mm x 1.60 mm and a maximum height of 1.30 mm. It has an ESD rank of 2 (2 kV) and a typical mass of 0.025 g. The part has no marking and is supplied in tape and reel packaging.
