CPS Current Sensing Resistor

CPS Current Sensing Resistor

CPS Current Sensing Resistor

Product catalog summary
Specifications:
The document outlines the specifications for CPS series current sensing resistors. The rated power ranges from 2W to 15W, with dimensions specified for each type. The resistance tolerance options include ±0.1%, ±0.25%, ±1%, ±5%, and ±10%. The temperature coefficient of resistance (TCR) is available in ±10PPM/℃, ±15PPM/℃, and ±25PPM/℃. The operating temperature range is from -55℃ to +275℃.
Features:
The CPS series resistors feature extremely low resistance values, low temperature coefficients, complete welded construction, superior anti-surge capability, and special inorganic sealing construction for high thermal conductivity and moisture resistance.
Ordering Information:
The ordering information includes the series name (CPS), power rating (2W to 10W), resistance tolerance (B, G, F, J, K), resistance value (e.g., R01 for 0.01Ω), and TCR (e.g., C6 for ±10PPM/℃).
Performance and Testing:
Performance tests include resistance tolerance, temperature coefficient, load life, withstand voltage, short time overload, and thermal shock. Specifications for these tests include a maximum working voltage of 1000V and various ΔR values indicating resistance change under different conditions.
Applications and Ratings:
The document provides a derating curve for ambient temperature versus rated power, indicating performance across a temperature range from -55℃ to 275℃.
