The WCF Series Carbon Film Resistors from Watts Electronics are manufactured using advanced high vacuum carbonizing plants to ensure a stable resistive film. These resistors are insulated with light brown lacquer and offer a broad spectrum of power ratings, including 0.125W, 0.25W, 0.4W, 0.5W, 1W, 2W, and 3W, all with a standard tolerance of ±5% and a TCR of ±1000 ppm/°C.
The series supports resistance values from 0.1 Ohm to 10 Meg Ohm (E 24 series). They are designed to operate within a temperature range of -40°C to +150°C and feature maximum working voltages up to 500V and maximum overload voltages up to 1000V, depending on the specific model. The resistors have undergone rigorous testing for terminal strength, resistance to soldering heat (350°C), solderability, temperature cycling, life testing (1000 hours at rated power), and resistance to solvents, ensuring reliability in various applications.
Dimensions vary across the series, with body lengths ranging from 3.3mm to 15mm and body diameters from 1.7mm to 5.0mm. Lead diameters range from 0.45mm to 0.75mm. The WCF series is suitable for general-purpose electronic applications where stable resistance and reliable performance are required.
