BLM21PG331SN1D

BLM21PG331SN1D is a ferrite bead from Murata in an 0805 (2012 metric) case with an impedance of 330 Ω ±25% at 100 MHz, and Murata's PIM record lists this part as In Production. Ratings with their temperature points: 1.5 A at +85 °C and 1.0 A at +125 °C; DC resistance 0.07 Ω maximum; dimensions 2.0 x 1.25 x 0.85 mm; operating range −55 °C to +125 °C. The final D is the 180 mm paper-tape reel at 4,000 pieces. The selection point is the PG material at 330 Ω — mid-range bead impedance with amp-class current for point-of-load rails and interface power pins. Selection advice: the same case on this site carries the 120 Ω BLM21PG121SN1D from the same series and material — same D-format reel, different impedance and DCR; the value field in the code is the part, so match it exactly.
