Power inductor PLEA85DCA series

magnetichigh-densitylow-loss

Product overview

• This series of power inductors has a maximum profile of 0.55 mm
• Proprietary low-loss magnetic materials enable highly efficient power-supply designs
• Designed for miniaturized, battery-powered wearables and similar devices

Summary
TDK introduced the PLEA85 series of high-efficiency power inductors for battery-powered wearables and other miniaturized devices. Mass production began in October 2023. The series achieves an industry-low profile through TDK’s newly developed low-loss magnetic material and thin-film processing techniques. The package and terminal design support high-density surface mounting, reduce misplacement during mounting and improve terminal strength for robust end-products.

Physical dimensions & package
Measures 1.0 mm (L) x 0.8 mm (W) x 0.55 mm (H). Bottom electrode with partially L-shaped side form improves mounting reliability and terminal strength.

Features & Applications

• Main applications: temperature sensing of LD for optical communication transceivers and LiDAR
• Main features: supports Au wire bonding that can be mounted inside the LD package
• Narrow tolerance (±1%) of both resistance and B value
