■ Product Overview
The CDRH62/64/73/74 Series are fully shielded, surface-mount power inductors engineered to deliver exceptional power handling in the tightest spaces. This family offers a strategic choice between two distinct footprints—6.5mm x 6.5mm (CDRH62/64) and 7.5mm x 7.5mm (CDRH73/74)—allowing you to optimize your PCB layout for either maximum miniaturization or higher current capacity.
■ Features Various high power inductors are superior to be high Saturation for surface mounting. ■ Applications Power supply for VTR, OA equipment, digital camera, LCD TV set, notebook PC, partable communication equipments, DC/DC converters, etc |  |
■ Benefit
Fully Shielded (Closed Magnetic Circuit)
Eliminates EMI Interference. The ferrite core is completely enclosed in a magnetic shield, preventing magnetic flux leakage. This protects sensitive nearby ICs and eliminates the need for complex EMC shielding in your layout.
Dual Footprint Strategy
CDRH62/64/73/74 Series Smt Power Inductor perfect Fit for Any Board. Choose the 6.5mm series for ultra-compact designs (e.g., mobile devices, wearables) or the 7.5mm series for higher inductance and current in standard power modules.
High Saturation Current (Isat)
Handles High Transient Loads. The robust wirewound construction and optimized core material prevent core saturation under high peak currents, ensuring stable performance in DC-DC converters during load steps.
Low DC Resistance (DCR)
Maximizes System Efficiency. Minimizes I²R power losses, reducing heat generation and improving battery life in portable applications.
RoHS Compliant & Tape/Reel Packaging
Ready for High-Speed Assembly. Choke coil inductor compatible with automated pick-and-place equipment for high-volume manufacturing.
