SRN8040-470M

The Bourns SRN8040-470M is a fixed inductor from the SRN8040 series, featuring a semi-shielded drum core wirewound construction with a ferrite core and magnetic epoxy resin coating. It offers an inductance of 47 µH with ±20% tolerance, measured at 100 KHz / 1 V. The component is rated for a saturation current of 1.4 A (30% inductance drop) and an RMS current of 1.5 A (40°C temperature rise). Maximum DC resistance is 190 mOhm. The inductor operates over a temperature range of -40°C to +125°C and is designed for surface mount assembly in a nonstandard package measuring 8.00 mm x 8.00 mm x 4.00 mm. The terminal finish is Sn/Ag/Cu, and the part is halogen free. Typical applications include power supply filtering and DC-DC converter circuits where moderate inductance and current handling are required.
