Product Overview
The ATE CS Series is a line of silicone-coated axial lead wirewound resistors designed to offer a superior alternative to glass-glazed ceramic resistors without compromising cost or performance. These resistors are engineered for high precision, extremely low temperature coefficient, and exceptional reliability, especially in harsh environments. The robust construction, featuring a chemically inert ceramic core, uniform texture, and integrated welding of the resistance wire and leads, ensures long-term stability. With a wide operating temperature range of -55C to +350C, the CS series is ideal for demanding applications where high performance and durability are critical.

Power Derating
CS series resistors can operate from -55C to +350C. For applications operating above +25C, linear power derating is required to maintain resistor lifespan. The graph below illustrates typical derating curves.
