UPR/UPSC Series Ultra Precision Metal Film Network Blocking
Product Details
Technical features
1. It is assembled from EE1/10 (RE55) finished high- precision metal film resistors, which meets the requirements of EE/RE series resistance quality consistency inspection items.
2. High stability/high reliability
3. Due to the optional compensation effect, it has the characteristics of low temperature coefficient and high precision , and is suitable for analog electronic circuits with precision electronic instruments.
4. Two specifications are available: UPR and UPSC series have roughly the same performance. UPSC has a smaller volume, but its minimum resistance has a larger limit
. 5. Operating temperature range: -10°C ~ +70°C
6. Resistor rated power : 0.2W (70℃) Resistor Maximum working voltage: 250V

Note: 1) The test temperature range of the temperature coefficient in the table is 25℃～85℃, and the supply beyond this test temperature range can be negotiated.
2) If the nominal resistance, nominal resistance deviation and temperature coefficient exceed the above indicators, the supply can be negotiated.
