Product Description
Product Overview
These are high-performance shielded power inductors designed for demanding applications. They feature a closed magnetic circuit for strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Their compact size belies a high current capability, reaching up to 60A, with excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these inductors offer high precision and low resistance. They operate across a wide frequency range, up to 5MHz and above, and are RoHS compliant (halogen-free).
