Susumu's Thin-Film Precision Resistor Series
Thin-film chip resistors offer high stability and reliability in precision measurement applications
Susumu’s RG-VP, RG-LL, and URG series of thin-film chip resistors offers outstanding performance characteristics, high stability, and excellent reliability.
The RG series and the ultra-high reliability URG series resistors are ideal for applications that require extreme precision and reliability, such as industrial instrumentation, test and measurement equipment, automotive electronics, and laboratory-grade scales. The URG and RG-LL series resistors boast the industry’s best absolute tolerance of resistance of ±0.01%, and the lowest Temperature Coefficient of Resistance (TCR), at ±2ppm/°C.
The resistors’ thin-film construction offers various advantages such as low noise, ranging from -25dB to -35dB, and support for high-frequency operation up to 1GHz. In the URG series in particular, the resistors also offer a highly linear TCR specification.
The RG series resistors offer excellent reliability, and the URG devices’ reliability is even better. For example, the maximum drift over 2,000 hours’ operation at 70°C is ±0.02% for the URG resistors, and ±0.05% for the RG parts. Humidity bias drift is ±0.05% after 2,000 hours for the URG and ±0.1% for the RG resistors. The URG series is also highly stable under any environmental conditions including exposure to atmospheric sulfur.
