# SRP4020TA\-R47M (Component)

## Description

Bourns SRP4020TA\-R47M automotive\-grade shielded power inductor\. Nominal inductance is 0\.47 µH ±20%, measured at 100 kHz and 1 V\. Electrical ratings at 25 °C: Q ≥ 10, 120 MHz typical self\-resonant frequency, 11\.2 mΩ typical / 14 mΩ maximum DCR, 8\.0 A Irms, and 12 A Isat \(20% inductance drop\)\. The part uses a carbonyl\-powder core, enameled\-copper winding, lead\-frame terminals with Sn finish, and has a 2\.0 mm maximum height\. Operating temperature is −55 °C to \+150 °C including self\-heating; rated Irms corresponds to a 40 °C temperature rise\. AEC\-Q200 compliant, RoHS compliant, halogen free, MSL 1, supplied 3000 pieces per 13\-inch reel\. \#commonpartslibrary \#inductor
