Murata Manufacturing has launched the world’s smallest chip ferrite beads: the BLM18SP_SH1 series. They are designed for engineers with the objective of aiding automotive power supply applications.
The BLM18SP_SH1 series of chip ferrite beads is made to provide automotive powertrain safety with the capability of withstanding temperatures of up to 150ÂºC. The product is especially designed for engineers who are working on noise suppression components that are present in power line circuits. Murata has also now started the shipment of BLM18SP_SH1 samples.
Why This Product Is Developed for Engineers
The electronic functions of automotive systems are being enhanced day by day. With this comes the need for improved noise suppression components for engineers.
Due to various recent developments in the automotive industry, cars are now fabricated with electric components like radar, cameras, electronic control units, and so on. To ensure a stable power supply to all components and to take countermeasures against the noise of power supplies, Murataâs world-smallest ferrite chips (pictured below) are developed with the main purpose of improving noise suppression.

The Construction and Design of Murataâs Ferrite Beads
Again, Murataâs BLM18SP_SH1 series chip ferrite beads are the very smallest of their kind: they are contained within packaging of 3.2 mm by 1.6 mm. At 125ÂºC, the ferrite chips handle large currents (120ohm/4A) that are considered suitable for power lines. This is helpful for engineers who are working with design specifications for internal and external electrodes at temperatures of up to 150ÂºC. The BLM18SP_SH1 seriesâ design specification helps in creating noise suppression for power lines.
The Specifications and Features of Murataâs Ferrite Beads
As compared to the conventional designs in the BLM21PG series, Murataâs BLM18SP_SH1 series comes with a base area that is 50% smaller than its predecessors. This is very beneficial for engineers working with nano designs.
The product is in compliance with AEC â Q200*5 and is designed to support up to 6A-rated current and an impedance of 1 kiloohm (kÎ©). It consists of five different components whose range comprises impedance values from 30Î© to 1kÎ©. It is operational at temperatures from â55Â°C to 125Â°C.
Further Advantages for Engineers
- The BLM18SP_SH1 seriesâ said miniaturised base area provides more flexibility to engineers who are designing automotive power supply circuits, particularly when compared to previous products.
- The series helps engineers by offering improved acquisition efficiency and impedance, followed by lower resistance.
- The series is used to aid engineers who need to meet the demands of designing modern advanced driving assistance systems, or ADAS.
- They help in radiating electromagnetic emissions based on reduced conduction.
Ultimately, the BLM18SP_SH1 seriesâ reduced base area grants plenty of flexibility to engineers when designing their required systems (particularly ADAS). Murataâs products are the worldâs smallest ferrite chips, and they are helping engineersâagain, especially in automotive applicationsâthanks to their improved efficiency and impedance.
