Wide Temp SMD Power Inductor SDR Series for PDA and Flash Memory Programmers

The SDR series unshielded high-current SMD power inductor features an unshielded open structure with cost advantage as its core competitiveness. Inductance range covers 1.0μH to 1200μH. Rated current is up to 4.5A.

The flat top design is suitable for automated pick-and-place assembly. It is compatible with vapour phase soldering and infrared reflow soldering processes, with soldering heat resistance of 260°C/10 seconds.

Operating temperature: -40°C to +85°C. Storage temperature: -40°C to +105°C.

It is widely used in PDAs, laptop DC-DC converters, PDA flash programmers, buck-boost converters, and set-top boxes.
