- To meet the growing demands of efficient power supply for automobile electronics, Murata introduces small chip ferrite beads for noise suppression
- These also provide manufacturers with more flexibility when designing automotive power supply circuits and supports autonomous driving
Therefore, Murata has introduced the BLM18SP_SH1 series of small chip ferrite beads (for noise suppression) for use in automotive power supply applications.
With a structural design that utilizes internal electrode fabrication technology, the new series brings improved impedance acquisition efficiency along with lower resistance, which leads to a large current.
In addition, commercialized in 0603(1608) inch (mm) size (1.6mm × 0.8mm) package, this series has a 50 per cent smaller base area compared to conventional products which are typically packaged in 0805(2012) inch (mm) size (2.0mm × 1.25mm). This provides manufacturers with more flexibility when designing automotive power supply circuits and helps to support more sophisticated autonomous driving with smaller in-vehicle components.
Along with this series for automotive power supply applications, Murata has two other series in 0603 inch size—the BLM18SP_SZ1 series for in-vehicle infotainment and the BLM18SP_SN1 series for consumer devices.
- Achieves approx. 50 per cent smaller base area compared to the conventional BLM21PG series
- Complies with AEC-Q200
- Supports up to 6A rated current or 1kΩ impedance (in the BLM18SP_SH1 series)
The company has started shipping samples, and volume production is scheduled to begin in June 2020.
