Introducing 150°C, 0402 size chip ferrite bead for automotive use

Murata Manufacturing Co., Ltd. has introduced the BLM15HG_BH series of 0402 size (1.0×0.5mm) chip ferrite bead with guaranteed temperature use at 150°C for automotive powertrain safety applications. This product is scheduled to start mass production in October 2017.

There has formerly been a guaranteed 125°C usage temperature product on the automotive market for noise suppression in the vicinity of mounted sensors, but the current product attains the 150°C guaranteed temperature usage needed by customers for high temperature applications. The use of a guaranteed 150°C product eliminates the need to avoid high temperature areas when installing, thereby granting greater freedom of design.

The BLM15EG_BH series has large impedance up to high frequency (vicinity of 1GHz), making it suitable for noise suppression over a wide frequency range.

Murata has already introduced a 150°C guaranteed temperature usage chip ferrite bead, which can be solder mounted, in the 0603 size (1.6×0.8mm) and 0805 size (2.0×1.25mm). Adding the 0402 size to the product lineup for the same series of 150°C guaranteed temperature usage chips contributes to space saving.
