BLM31K Series High Rated Current SMD Ferrite Beads

Murata's BLM31K series of wide frequency, high rated current noise suppression

Image of Murata's BLM31K Series High Rated Current SMD Ferrite BeadsMurata's BLM31K series are the ideal ferrite beads for power supply circuits that require high rated current. The BLM31K series has achieved the highest impedance at 6 A with a small case size (EIA/1206, 3.2 mm X 1.2 mm X 1.2 mm). The rated current of the BLM31K series (1206 size) is better than large case size ferrite beads that were previously only available in 1210 and larger case sizes thus the BLM31KN contributes to space savings in power supply circuits.

The BLM31K series are most suitable for suppressing high frequency noise over a wide frequency range in power supply circuits and additionally are certified AEC-Q200 making them ideal for automotive applications such as infotainment and power train safety applications.

There are also non-automotive grade product versions within the BLM31KN series line up ideal for general purpose power supply circuit usage such as industrial, test equipment, factory automation, and networking.

Features
  • High impedance and high rated current at 1 GHz to 3 GHz
  • AEC-Q200 compliant and safety application is also acceptable
  • -55°C to +125°C operating temperature
Applications
  • Automotive: infotainment, ECU, TPMS, powertrain
  • Networking
  • Industrial
  • Factory automation
  • Test equipment
