B65887E0***A087 is a magnetic component of the RM cores RM14 series/type produced by EPCOS.
The RM14 series are ferrite cores offered by EPCOS. The datasheet lists magnetic parameters such as effective air‑gap length, inductance, and core dimensions, as well as the approximate weight per set. These specifications help designers select the appropriate core for their magnetic circuits.
The document also contains important cautions and processing notes. Ferrite cores are brittle ceramic materials; they must be protected from mechanical shock, fast cooling, and excessive soldering temperatures. Proper handling, winding, and PCB drilling guidelines are provided to ensure reliable performance.
| LWA | 0.35 mm |
|---|---|
| Ae | 200 mm? |
| Amin | 170 mm? |
| Ve | 14000 mm? |
| Approx. weight | 74 g/set |
The magnetic parameters are measured at 10 kHz, 0.25 mT, 100 turns, and room temperature.
Ferrite cores should be protected from mechanical shock, fast cooling, and excessive soldering temperatures above 300 °C, and winding forces should be kept soft.
The cores are supplied in standard styrofoam trays measuring 300 × 200 × 60 mm.
