SRF1306-350Y is an EMI suppression line filter from Bourns designed for high-frequency noise filtering applications. It features an inductance of 35 ± 35 % µH, a maximum DC resistance of 0.035 O per winding, and a rated current of 2.7 A at 50 Vdc. The device operates across a frequency range of 5–250 MHz with a maximum leakage inductance of 4 µH, providing effective impedance control for EMI mitigation. The filter is RoHS compliant and constructed with ferrite core material, enameled copper wire, and tin-coated terminals, ensuring reliability and environmental compliance. Common applications include power supply filtering, signal line protection, and EMI suppression in high-speed digital and RF systems where broadband noise rejection is required.
