This document is about the data sheet of B65525-J0000-R097 ER core ER11/5
This data sheet provides the magnetic characteristics of the ER11/5 ferrite core, including permeability (l/A = 1.137 mm⁻¹), effective length (le = 14.1 mm), cross‑sectional area (Ae = 12.4 mm²), and volume (Ve = 174 mm³). It also lists the approximate weight (0.85 g per set), standard packaging, and measurement parameters such as AL value at 10 kHz/0.25 mT and 100 kHz/200 mT.
The document includes cautions about the brittle nature of ferrite ceramics, mechanical stress limits, and processing notes for winding and soldering. Legal disclaimer text clarifies EPCOS' liability and references additional material data sheets.
| Permeability (l/A) | 1.137 mm⁻¹ |
|---|---|
| Effective length (le) | 14.1 mm |
| Cross‑sectional area (Ae) | 12.4 mm² |
| Minimum area (Amin) | 10.3 mm² |
| Volume (Ve) | 174 mm³ |
| Approximate weight | 0.85 g per set |
| AL value measurement (10 kHz) | f = 10 kHz, B = 0.25 mT, 100 Turns, T = 25 °C |
| AL value measurement (100 kHz) | f = 100 kHz, B = 200 mT, T = 100 °C |
The core weighs about 0.85 g per set.
Ferrite cores are brittle ceramic materials; avoid mechanical shock, high static or cyclic loads, and excessive ultrasonic cleaning to prevent cracks.
The winding process should be soft; excessive winding force can destroy the flanges or squeeze the tube.
AL is measured at 10 kHz with 0.25 mT bias, 100 turns, 25 °C, and at 100 kHz with 200 mT bias, 100 °C.
