This document provides detailed parameter information of the EPIXXXXXXAC5 series, including advantages, application range, specifications, and packaging, which can be used for selection
The EPIXXXXXXAC5 series are thru‑hole power inductors optimized for National’s LM257X series and other high‑frequency switching converters such as buck and boost regulators. They feature low loss material, a lead‑free option (‑LF) and are suitable for high‑quality filter applications.
The datasheet lists primary specifications for each part number, including inductance, DCR, core loss, temperature rise, lead finish, solder rating, weight and packaging details. Mechanical dimensions, pad layouts and mounting options (vertical or horizontal) are also provided.
| Inductance (µH) | 220 |
|---|---|
| DCR (mΩ) | 260 |
| Core Loss (mW) | 3000 |
| Temperature Rise (°C) | 23 |
| Lead Finish | SnPb Hot Tin Dip (Sn) |
| Peak Solder Rating (°C) | 225 / 260 |
| Weight | 51 grams |
The "-LF" suffix indicates a lead‑free version of the part.
The peak solder rating is 225 °C for standard and 260 °C for wave solder processes.
Each inductor weighs 51 grams.
Package options include AC5V, AC5, and AC5H, with vertical (V) or horizontal (H) mount variants.
