SRF1006-251Y is an EMI suppression line filter from the SRF1006 Series designed to attenuate electromagnetic interference in electronic circuits. It features a nominal inductance of 250 µH (±40% tolerance) with a maximum leakage inductance of 3.2 µH and a DC resistance of 0.035 O per winding. The device is rated for 1.19 A continuous current at 50 Vdc and operates effectively across the 5–100 MHz frequency range, with a minimum impedance value of 400 O. Constructed with a ferrite core, phenolic base, enameled copper wire, and tin-coated terminals, this RoHS-compliant component is ideal for power supply filtering, signal line protection, and general EMI suppression applications in consumer electronics, industrial equipment, and telecommunications systems.
