This document describes the features and characteristics of CW, CWP coated insulated, precision wirewound leaded resistors, including flameproof silicone coating, suitable for automatic machine insertion, color-coded marking, compliance with RoHS requirements, etc.
KOA Speer Electronics offers the CW and CWP series of coat‑insulated, precision miniature wirewound resistors. These components feature a flame‑proof silicone coating (UL94V0), blue‑gray bodies with color‑coded bands, and lead‑free terminations that meet EU and China RoHS requirements.
The data sheet lists power ratings from 0.25 W to 5 W, resistance ranges from 0.1 Ω to 390 Ω, and temperature coefficients as low as 20 ppm/°C. Detailed environmental performance includes moisture resistance, solder‑heat endurance, and high‑temperature capability up to 470 °C. Ordering information, part numbers, and packaging details are also provided.
| RoHS compliance | Lead‑free terminations meet EU and China RoHS |
