This document introduces the surface mount power inductor products of Dinghao Electronics Inc. These products are optimized for National's LM259X series and can operate in high frequency switching converters, such as Buck, Boost, or as output averaging filter inductors. They are also suitable for high-quality filter applications. The document lists the specifications of different models of inductors, including inductance, DC resistance, operating temperature, etc.
The EPI B20 Series surface‑mount power inductors are optimized for National’s LM259X series and feature low‑loss material for high‑frequency switching converters such as buck, boost, or output averaging filter applications. They operate at switching frequencies from 150 kHz to 500 kHz and are suitable for high‑quality filter uses.
The document lists primary specifications for each part number, including DCR, inductance, current rating, core loss, and temperature rise. It also shows a typical application circuit, package information (B20), coplanarity tolerance, and contact details for PCA Electronics.
