Overview
This document provides technical specifications and performance details for RSS Wire Wound Resistors, designed by Shenzhen KWX Electronics Co., Ltd. These resistors are characterized by their flameproof and insulating coating, heat durability, low noise, and long service life. They comply with EU RoHS standards.

Construction and Features
The resistors are constructed with a lead wire, cap, ceramic base, wire wound, marking or color code, and insulation coat. They are designed to be flameproof with a non-flammable silicon base equivalent to UL94V-0.

Specifications
- Power ratings range from 1W to 9W.
- Resistance ranges from 0.05Ω to 10KΩ.
- Maximum working voltage varies from 50V to 500V.
- Temperature Coefficient of Resistance (T.C.R) varies based on resistance value, from ±50PPM/℃ to ±600PPM/℃.

Dimensions
The dimensions are specified in millimeters with variations in length (L), diameter (D), and height (H) depending on the power rating.

Performance and Testing
The resistors undergo various performance tests including resistance, T.C.R, short time overload, load life, moisture resistance, temperature cycle, solderability, and resistance to soldering heat. They meet specified tolerances and performance requirements as per JIS C 5201-1 standards.

Ordering Information
Ordering codes are structured by series name, power rating, resistance tolerance, resistance value, and lead wire type. Custom designs are available for specific resistance values and current circuits.

Graphs and Curves
The document includes derating curves, surface temperature rise graphs, and pulse test curves to illustrate performance under various conditions.
