It provides 1 kOhms impedance at 100 MHz, sized for suppressing conducted noise on signal lines in space-constrained designs. Rated for 300 mA continuous current with a maximum DC resistance of 650 mOhm — the DCR sets the voltage drop and self-heating under load, so the 300 mA ceiling is the practical limit before the temperature rise exceeds the bead's derating curve. ## Impedance vs current — the real-world derating The 1 kOhms impedance is specified at 100 MHz — the bead's peak suppression band. At lower frequencies the impedance drops; at DC it is just the DCR of 650 mOhm, so the bead does not attenuate power-line ripple below the MHz range. Under bias current, the ferrite core saturates and the effective impedance decreases. At 300 mA the bead may deliver only 50–60% of its rated impedance at 100 MHz — design the noise margin with this derating in mind, especially on supply lines where the DC bias is continuous. ## Procurement and lifecycle status The base product number BLM15AG covers the family; the full suffix (102SZ1D) encodes the impedance value, material grade, and packaging. Tape-and-reel (TR) or cut-tape (CT) options are listed — the reel quantity is standard for 0402 chip beads.","metaTitle":"BLM15AG102SZ1D Murata Ferrite Bead, 1 kOhm @ 100 MHz, 300 mA","metaDescription":"Murata BLM15AG102SZ1D EMI filter ferrite bead, 1 kOhm impedance at 100 MHz, 300 mA rating, 0402 package.
