SRN6045TA-4R7M is a semi-shielded power inductor from Bourns designed for use in switching power supplies, DC-DC converters, and other power management circuits. The inductor features a nominal inductance of 4.7 µH with ±20% tolerance, a quality factor (Q) of 15 at 1 MHz, and a self-resonant frequency (SRF) of 40 MHz. It is rated for a continuous RMS current (Irms) of 4.5 A with a saturation current (Isat) of 6.8 A, and exhibits a DC resistance (DCR) of 26 mO. The device is constructed with a ferrite core, enameled copper wire, and magnetic epoxy resin coating, and is AEC-Q200 compliant, RoHS compliant, and halogen-free. It operates with a temperature rise of 40°C at rated current and is suitable for automotive and industrial applications requiring reliable power inductance in compact form factors.
