SRR0745A-271M is a shielded power inductor from Bourns' SRR0745A series designed for compact switching power supply and DC-DC converter applications. The device features a 270 µH inductance at 1 kHz with ±20% tolerance, a maximum DC resistance of 1.2 O, and is rated for 0.38 A RMS and 0.46 A saturation current. It incorporates a ferrite core with enameled copper windings and operates reliably across a temperature range of -40°C to +125°C with a typical temperature rise of 40°C at rated current. The compact 7.3 × 7.3 × 4.5 mm shielded construction, combined with AEC-Q200 qualification and RoHS compliance, makes it ideal for automotive and industrial power management circuits requiring high reliability and minimal electromagnetic interference.
