Taiyo Yuden BKP1005EM121-T 120 Ohm 1.55A 0402 SMD Ferrite Beads 250 Pieces
$12.95
Lot of 250 genuine Taiyo Yuden BKP1005EM121-T multilayer SMD ferrite bead inductors supplied in an original Digi-Key distributor-labeled packet. These compact 0402 ferrite beads provide 120-ohm impedance at 100 MHz with ±25% tolerance and are designed for high-frequency noise suppression on DC power and signal lines.
Technical specifications include a 1.55-amp maximum rated current from -55°C to +85°C, 0.9-amp maximum rated current through +125°C, 85-milliohm maximum DC resistance, and a -55°C to +125°C operating range. The component measures approximately 1.0 × 0.5 × 0.5 mm and is suitable for reflow soldering. RoHS compliant, REACH compliant, halogen-free, and lead-free.
Typical applications include power-line noise filtering, USB and IEEE 1394 interface suppression, mobile electronics, communications equipment, computer hardware, battery-powered circuits, test equipment, industrial control boards, and component-level PCB repair.
Historical Note: Taiyo Yuden’s BKP series was developed as a low-DC-resistance multilayer ferrite bead family for high-current power-line noise suppression. The BKP1005EM121-T is now a phased-out legacy component, making original distributor-stock quantities useful for repair, restoration, and support of existing equipment designed around this exact part.
