CDRH124/125/127/129 Series Wirewound Inductor

Benefits

Compact & Versatile Form Factor: Available in multiple height profiles (CDRH124: 4.5mm, CDRH125: 6.0mm, CDRH127: 8.0mm) while maintaining a consistent 12mm x 12mm footprint. This allows designers flexibility in meeting PCB height and performance requirements.

Full Magnetic Shielding (Closed Core): The shielded construction prevents magnetic flux leakage, significantly reducing noise and preventing interference with adjacent sensitive components. This makes them ideal for noise-sensitive applications.

High Saturation Current & Low DCR: Engineered for high power density, these wirewound inductors offer excellent saturation current ratings (e.g., up to 10.4A for CDRH127-1.0uH) alongside low DC resistance (DCR), ensuring high efficiency and minimal power loss in your power path.

Robust Construction: Featuring a durable wirewound design on a ferrite core, wirewound inductors are built to withstand the rigors of automated SMT assembly and provide long-term reliability.
