BLM15PX221SN1D 220 Ohm 0402 Power Line Ferrite Bead

BLM15PX221SN1D is a 0402 surface-mount ferrite bead for suppressing high-frequency noise on DC power lines. It provides 220 ohms impedance at 100 MHz with a ±25% tolerance and a maximum DC resistance of 0.10 ohm. Rated current is 1.4 A at 85°C and 0.8 A at 125°C, with current derating applied across the higher temperature range. The specified operating range extends from -55°C to 125°C. Its combination of compact size, controlled impedance, and low series resistance fits power filtering in dense electronic assemblies. Placement remains straightforward on crowded boards. Engineers can place it in DC supply paths where unwanted high-frequency energy needs attenuation without adding a large discrete filter network. Request a quote for BLM15PX221SN1D.
