The CDH64 Series is a wire-wound, SMD Shielded Power Inductor that offers an excellent balance of high inductance and a compact footprint. It shares the same 6.2 mm × 6.6 mm footprint as the ultra-slim CDH62 but features an increased height of 5.0mm.
This increased profile allows for a wide inductance range (up to 330µH), including the common 100uh inductor value (CDH64-101M). The CDH64's closed magnetic circuit design effectively reduces leakage flux and EMI, making it ideal for a power inductor circuit. It also offers a higher current rating than conventional non-shielded inductors of the same size. If you are asking what are inductors used for, the CDH64 is a perfect example of a versatile component for power conversion.
Key Features
Magnetically Shielded: Closed magnetic circuit design for low EMI.
Compact Footprint: 6.2 mm × 6.6 mm.
Standard Profile: 5.0mm maximum height for an enhanced inductance range.
Wide Inductance Range: 10µH to 330µH.
Higher Current Rating: Outperforms conventional unshielded inductors.
RoHS Compliant.
