Product Description
MMPC0302 Series High Current Molded Power Inductors
The MMPC0302 Series High Current Molded Power Inductors are designed for demanding power applications. Featuring a compact design with carbonyl powder cores, these inductors offer high current handling, low DCR, and high efficiency, enabling operation at frequencies up to 5MHz. They are particularly well-suited for PC power systems, including IMVP-6 DC/DC converters, and provide very low acoustic noise and leakage flux noise. These inductors are RoHS compliant.
