The BOURNS SRF0905-501Y is a dual common mode choke designed for use in electronic circuits prone to electromagnetic interference (EMI). With a high inductance of 500uH, it effectively suppresses unwanted high-frequency noise signals by providing a common path for them to cancel each other out. Featuring a 1kOhm impedance at 100kHz and a rated current of 1A, this SMD-compatible choke is ideal for applications requiring a high level of EMI filtering. It also offers a low DC resistance of 0.15Ohm, minimizing power losses and ensuring efficient performance. Suitable for surface-mount device (SMD) placement, the BOURNS SRF0905-501Y is supplied in tape and reel packaging for ease of handling during production.
