The BLM21HE collection of chip ferrite beads from Murata present powerline noise suppression, together with high-frequency points inside high-current automotive methods. Even at 1 GHz, BLM21HE802XXX units usually attain impedance values of 850 Ω.
This makes the elements helpful for addressing the sign integrity of next-generation automobile designs the place high-current powerlines will probably be in shut proximity to high-frequency communication-related features. The chip ferrite beads can be utilized in wi-fi battery administration system (wBMS) infrastructure and vehicle-to-vehicle communication methods.
With a large band of 100 MHz to 1 GHz and excessive impedance, the BLM21HE collection suppresses high-frequency noise, in addition to standard noise frequencies. Additional, the low DC resistance values of those chip ferrite beads leads to minimal energy loss, bettering effectivity and decreasing the quantity of thermal administration wanted to dissipate any generated warmth.
BLM21HE chip ferrite beads are available in variations that function over temperature ranges of -55°C to +125°C and -55°C to +150°C. They’re housed in surface-mount 0805 instances (2.0×1.25×1.25 mm) and will be bought by Murata’s distributor community.
