Murata Develops 1005 Ultra-Small Noise Suppression Components

Noise countermeasure components that help provide stable power supply are essential for more automotive components to function properly and achieve a high degree of safety. Among them, the number of chip ferrite beads used in each car reaches hundreds, so it is necessary to reduce the size while improving the noise reduction performance.

Murata Develops 1005 Ultra-Small Size (1.0 x 0.5 mm) Noise Countermeasure Components for Automotive Power Lines - Chip Ferrite Beads "BLM15PX_SH1/BH1 Series"

Murata's chip ferrite bead "BLM15PX_SH1/BH1 series" has a new structure design using its unique internal electrode forming technology, which can generate high current and low internal resistance while achieving higher impedance characteristics. Compared with Murata's conventional product 1608 size (BLM18PG series), the mounting area is reduced by about 60% under the same performance conditions, realizing miniaturization. This increases the degree of freedom in the design of power lines for in-vehicle equipment, and supports the high-end autonomous driving system through further miniaturization of in-vehicle equipment.

Features

• Ultra-small chip ferrite beads for automotive power lines, 1005 size, 120Ω impedance, 2A rated current (at 85°C)

• In addition to our company's unique high-aspect-ratio electrode forming technology and high-impedance acquisition technology, we have also established a new microfabrication technology to meet AEC-Q200(2) while maintaining high performance, and at 150°C (BH series ) can be used in the following environments

• Suitable for powertrain and safety applications

• The operating temperature is divided into two product lineups: -55 to 125°C products (SH series) and -55 to 150°C products (BH series)

• Lineup: Impedance 33Ω (at 100MHz) / rated current 3A (at 85°C) to 600Ω / 900mA (same conditions)

• Low DC resistance (Rdc), ranging from 0.022Ω (BLM15PX330) to 0.23Ω (BLM15PX601), reduces power loss and heat generation
