SRN4018TA-330M is a semi-shielded power inductor from Bourns designed for compact power conversion and filtering applications. It features an inductance of 33 µH at 100 kHz with ±20% tolerance, a DC resistance of 0.405 O, and a self-resonant frequency of 12 MHz. The inductor is rated for 0.75 A RMS continuous current with a saturation current of 0.75 A, and operates reliably across a temperature range of -55°C to +125°C with a 40°C temperature rise at rated current. The device is constructed with a ferrite core, enameled copper wire, and magnetic epoxy resin coating, making it RoHS compliant and halogen-free. This inductor is ideal for DC-DC converters, power supplies, and RF filtering circuits where space constraints and thermal management are important considerations.
