BLM31PG391SN1L Description

Short technical summary and product information.

The BLM31PG391SN1L is a surface-mount chip ferrite bead from Murata's BLM31_SN series. It provides 390 Ω typical impedance at 100 MHz and is designed for power line filtering in a single-line configuration. The component is rated for 2 A DC current at 85°C ambient, derated to 1.25 A at 125°C, with a maximum DC resistance of 50 mΩ.

 

The ferrite bead is housed in a 1206 (3216 Metric) package measuring 3.20 mm x 1.60 mm with a maximum height of 1.30 mm. It operates over a temperature range of -55°C to +125°C and is suitable for surface-mount assembly, available with tape-and-reel packaging.

 

Per the Murata BLM31_SN reference specification, this series is intended for consumer equipment, industrial equipment, certain medical equipment (GHTF Class A/B/C), and power equipment applications such as renewable energy, energy storage, and EV charging systems. The component is not intended for applications that directly protect human life or property.
