■ Applications
The CDRH83/84/85/86 Series smd power inductors offers a scalable solution within a consistent 8.3mm x 8.3mm footprint. By varying the height from 3.0mm to 6.0mm, this series allows engineers to precisely select the right balance of current capacity, inductance range, and Z-height for applications ranging from compact consumer electronics to robust power systems.
■ Features Various high smd 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 | ![]() |
■ Benefits
Scalable Power in a Fixed Footprint:
Simplify your PCB library and design process. Maintain the same land pattern while scaling power by choosing a taller series.
High Saturation Current:
SMD power inductors are designed to handle high transient and DC loads without core saturation, ensuring stable voltage regulation.
Low DC Resistance (DCR):
Minimizes conduction losses (I²R), improving overall system efficiency and thermal performance.
Fully Shielded Construction:
The closed magnetic structure prevents EMI and minimizes coupling with nearby components, critical for dense, high-speed designs.
Robust & Reliable:
SMD power inductors are built with a durable wirewound design on a ferrite core, suitable for automated SMT assembly and capable of operating in demanding environments.
