BLM21PG121SN1D

BLM21PG121SN1D is a ferrite bead from Murata in an 0805 (2012 metric) case with an impedance of 120 Ω ±25% at 100 MHz, and Murata's PIM record lists this part as In Production. Ratings with their temperature points: 3 A at +85 °C and 1.55 A at +125 °C; DC resistance 0.03 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 current-to-impedance trade in the PG series: this is the 3 A member, where the sibling BLM21PG331SN1D in the same case trades current (1.5 A) for impedance (330 Ω) — the two share case, material and reel format and are not substitutes. Selection advice: pick by which side of the trade your rail sits on, and write the full code in the RFQ; a one-field difference here is a different bead.
