The Murata BLM31PG121SN1L is a chip ferrite bead designed for power line filtering applications. It offers a typical impedance of 120 Ω at 100 MHz, with a maximum DC resistance of 20 mΩ and a rated current of 3.5 A at 85°C ambient temperature. At 125°C, the current rating derates to 2.0 A. The component operates over a temperature range of -55°C to +125°C and is suitable for consumer, industrial, and medical equipment as per the reference specification.
This ferrite bead is housed in a standard 1206 (3216 metric) surface mount package with dimensions 3.20 mm x 1.60 mm and a maximum height of 1.30 mm. It is a single-line filter, ideal for suppressing high-frequency noise on DC power supply lines. The part is RoHS3 compliant and has an MSL rating of Level 1 (unlimited).
Designed for use in power equipment, industrial robotics, base stations, and medical devices (GHTF Class A/B/C), the BLM31PG121SN1L provides reliable EMI suppression without compromising current handling capability. Its low DCR minimizes power loss, making it efficient for high-current circuits.
