The 300 mA continuous current rating sets the DC bias ceiling; above that the ferrite core saturates and the impedance collapses. ## Temperature grade and automotive qualification The AEC-Q200 qualification (passive-component stress test) covers thermal shock, solder heat resistance, vibration, and humidity bias — the bead is screened for the reliability profile an engine-bay or cabin ECU demands. No derating is needed across the band; the impedance curve shifts slightly with temperature but the 220 Ohm peak stays within spec.","metaTitle":"Murata BLM15AG221SH1D Ferrite Bead, 220 Ohm @ 100 MHz, 0402","metaDescription":"Murata BLM15AG221SH1D EMIFIL ferrite bead, 220 Ohm @ 100 MHz, 300 mA, 350 mOhm DCR, AEC-Q200, 0402 package.
