The BLM21SN300SH1D is a chip ferrite bead from Murata's BLM21 series, designed for power line filtering in automotive and other high-reliability applications. It offers a typical impedance of 30 Ω at 100 MHz, with a maximum DC resistance of 4 mOhm and a high current rating of 8.5 A at 85°C ambient temperature.
This single-line ferrite bead is surface-mounted in an 0805 (2012 Metric) package, with dimensions 2.00mm x 1.25mm and a maximum height of 1.05mm. It operates over a wide temperature range of -55°C to +125°C, making it suitable for harsh environments.
The component is AEC-Q200 qualified, ensuring reliability for automotive powertrain, safety, infotainment, and comfort systems. It is also suitable for medical equipment (GHTF Class C and below) as per the datasheet specifications. The termination style is SMD/SMT, and it is supplied in tape and reel packaging (paper tape).
For design engineers, the low DCR and high current capability minimize power loss and heat generation in power supply lines. The impedance at 100 MHz provides effective suppression of high-frequency noise. The ferrite bead is RoHS3 and REACH compliant (unverified), and has an MSL level of 1 (unlimited floor life).
