SRF0602-331Y is a surface-mount line filter inductor from Bourns' SRF0602 series, engineered for electromagnetic interference (EMI) suppression in high-frequency applications. The device features an inductance of 330 µH (±50%), a maximum DC resistance of 0.30 O per winding, and a rated current of 300 mA, with a maximum leakage inductance of 10 µH. Operating across a frequency range of 3–120 MHz with a minimum impedance of 900 O, it delivers effective noise filtering in compact form. The component is rated for 50 Vdc and operates reliably from -40°C to +105°C, making it suitable for power supply filtering, signal line protection, and EMI mitigation in consumer electronics, telecommunications, and industrial equipment where space constraints and high-frequency performance are critical.
