The Bourns SRU1028-330Y is a shielded SMD power inductor from the SRU1028 series, featuring a 33µH inductance with ±30% tolerance. It offers a high current rating of 1.25A RMS and a saturation current of 1.2A typical, with a low DC resistance of 139mΩ for efficient power handling. The inductor is constructed with a ferrite drum core and enameled copper wire, with silver/nickel/tin terminals for reliable solder connections. Its shielded design minimizes magnetic interference, making it suitable for power supply applications. The component operates over a temperature range of -40°C to +125°C including temperature rise, and withstands soldering heat up to +260°C for 10 seconds. The package measures 10.0mm x 10.0mm with a height of 2.8mm, and is supplied in tape and reel packaging with 1000 units per reel.
This inductor is designed for input/output filtering in DC/DC converters and power supplies for portable communication equipment, camcorders, and LCD TVs. The self-resonant frequency is a minimum of 12MHz, and the Q factor is 24 at 2.52MHz, indicating good performance in high-frequency applications. The part is RoHS compliant and has an MSL rating of 1 (unlimited).
