This document is an introduction to the surface mount power inductors produced by PCA Electronics, Inc. These inductors are optimized for National's LM259X Series and are suitable for high frequency switching converters, such as Buck or Boost converters, as well as output averaging filter inductors. They are also suitable for high quality filter applications. The product has a switching frequency of 150kHz and 500kHz and is a low-cost inductor.
The EPI B20 Series is a line of surface‑mount power inductors featuring low‑loss material for high‑frequency switching converters such as buck, boost, and output‑averaging filter applications. The series is specifically optimized for National’s LM259X Series and is also suitable for high‑quality filter applications.
The document lists primary specifications for each part number, including switching frequency range, DCR, inductance, and current ratings. Mechanical details cover the B20 package dimensions, coplanarity tolerance of .005 inch, and layout recommendations. Contact information for PCA Electronics is provided at the end of the sheet.
