BLM18EG471SN1D Description

Short technical summary and product information.

The BLM18EG471SN1D is a GHz noise suppression chip ferrite bead from Murata, designed for use in consumer, industrial, and medical equipment. It provides a typical impedance of 470Ω at 100MHz, with a minimum of 340Ω at 1GHz, making it effective for high-frequency EMI filtering. The component is rated for a maximum DC current of 500mA and features a low DC resistance of 0.21Ω (initial) and 0.30Ω (maximum after testing).

 

The ferrite bead is housed in a standard 0603 (1608 metric) surface-mount package with dimensions 1.60mm x 0.80mm and a maximum height of 0.95mm. It operates across a temperature range of -55°C to +125°C, suitable for demanding environments. The single-line design simplifies PCB layout for power line and signal line noise suppression.

 

Compliance information indicates RoHS3 compliance, MSL level 1 (unlimited), and REACH unaffected status, though these are unverified. The part is typically supplied in tape and reel packaging (inferred). Applications include power supply lines, high-speed digital interfaces, and general filtering in electronics where size and frequency performance are critical.
