Halogen-free and RoHS Compliant Sumida CD30D22 Series Power Inductors are designed for use in portable devices and DC-DC converters with high-density power circuitry. The magnetically unshielded design is based on a ferrite drum construction with an exclusive core geometry. This design allows higher inductance values than many other coils of similar volume. The CD30D22 measures just 3.6 x 3.0 x 2.2 mm, with about two-thirds of its footprint devoted to circuit contact area.
Inductance values range from 1.0 μH – 270 μH over 21 parts. DCR is as low as 28.7mW (typ.@ 20°C). Current handling capabilities are also above average, with a full-rated temperature range of -40° to +125°C.
Applications include DC-DC converters, switching power supplies and regulators, boost converters, buck-boost regulators and more. Highly shock resistant, they are well suited for use in such products as cell phones, two-way radios, portable test instruments and networking devices. Standard packaging is carrier tape and reel packaging, 7.0”diameter reel, 500pcs per reel. Solder reflow temperature to 260°C peak. JEDEC/IPC Moisture Level Sensitivity is Level 1 (highest rating).
Like other Sumida products, the CD20D22 is assembled from components designed and manufactured within the company. This allows the highest possible level of quality control.
