Coilcraft has expanded its portfolio with the low-profile MVR series of shielded power inductors, designed to meet the high-performance needs of voltage regulator modules (VRM) and voltage regulator-down (VRD) controllers. These inductors are optimized for high-current DC-DC converters and offer several standout features:
- Thermal Stability: Built using high-temperature, low-loss materials that resist thermal aging.
- Exceptional Current Handling: With very low DC resistance (DCR), the MVR inductors are capable of managing high currents while minimizing power loss.
- Compact Design: The series features a low-profile construction that offers an excellent performance-to-height ratio, making them ideal for high-density applications.
- Magnetic Shielding: The inductors feature shielding that minimizes electromagnetic interference (EMI) and allows for closer component placement, enhancing the efficiency of power supply designs.
