KV Electronics Output Filter Inductors are high-reliability single-winding inductors designed specifically to smooth DC output current, minimize ripple voltage, and filter out high-frequency switching noise in power supply circuits. Available in versatile core configurations including toroid, drum core, and rod core geometries.

These inductors are optimized for low DCR to minimize conduction losses while maintaining sufficient inductance to achieve target ripple specifications. Custom inductance values, saturation current ratings, and form factors are available for OEM power supply designs.

Key Features

• Inductance: 1μH – 10mH
• Saturation current: 0.5A – 50A
• Core types: toroid, drum core, rod core, E-core
• Low DCR for minimal conduction loss
• Soft saturation characteristic (toroid cores)
• Through-hole and chassis-mount options
• RoHS3 compliant; custom bobbin available

Applications

• Buck converter output filter
• Linear power supply choke
• DC-DC converter output stage
• Battery charger output filter
• POL (Point-of-Load) converters
