SRP3020C-4R7M is a shielded power inductor from Bourns' SRP3020C series designed for high-current power conversion applications. It features a 4.7 µH inductance with ±20% tolerance, a metal alloy powder core, and shielded construction to minimize electromagnetic interference and buzz noise. The inductor exhibits a typical DC resistance of 167 mO (maximum 200 mO), a saturation current of 2 A typical, and an RMS current rating of 1.8 A, with a self-resonant frequency of 29 MHz. Operating over a temperature range of -40°C to +125°C with a 40°C temperature rise at rated current, this component is RoHS compliant and halogen-free. It is commonly used in DC-DC converters, switching power supplies, and other power management circuits where compact size, low noise, and reliable inductance stability are required.
