BLM15EG121SN1D Description

Short technical summary and product information.

The BLM15EG121SN1D is a chip ferrite bead from Murata's BLM15E_SN series, designed for general-purpose noise suppression. It provides a typical impedance of 120 Ω at 100 MHz with a tolerance of ±25%, and a minimum impedance of 100 Ω at 1 GHz. The DC resistance is 95 mΩ maximum, ensuring low power loss.

 

Rated current is 1.5 A at 85°C, derated to 0.9 A at 125°C. The component operates over a temperature range of -55°C to 125°C. It is housed in a compact 0402 (1005 metric) surface mount package, measuring 1.0 mm × 0.55 mm × 0.55 mm, with a mass of 0.001 g.

 

This ferrite bead is suitable for EMI filtering in high-density PCB designs, particularly in power supply lines and high-speed signal lines. The single-line configuration and small footprint make it ideal for space-constrained applications.
