UPRNS/UPRND series ultra precision metal film resistor, technical characteristics of network voltage divider 1. It is assembled by selecting EE1/10 (RE55) finished high-precision metal film resistor, meeting the requirements of EE/RE series resistance quality consistency inspection items. 2. High stability/high reliability 3. Excellent consistency: the nominal resistance value deviation and temperature coefficient of the component resistance have relative consistency, especially applicable to electronic circuits with technical requirements such as precise voltage division and shunt. 4. Various specifications: users can select the quantity, specification, absolute and relative resistance value deviation, absolute and relative temperature coefficient and structure form of the component resistance within the range specified in this specification, and design the required resistance network by themselves. 5. UPRNS is single in-line type and UPRND is dual in-line type. 6. Working temperature range: - 10 ℃~+70 ℃ 7. Rated power of single component resistor: 0.1W (70 ℃), maximum working voltage of single component resistor: 200V. If the customer's requirements are beyond the scope of this specification, it is also allowed to negotiate the ordering outline structure dimension (mm) Basic structure diagram UPRNS/UPRND series technical parameters Nominal resistance deviation absolute A2 (± 0.02%) A5 (± 0.05%) B (± 0.1%) C (± 0.25%) D (± 0.5%) F (± 1.0%) Relative T (0.01%) A2 (0.02%) A5 (0.05%) B (0.1%) Temperature coefficient absolute C7 (± 5ppm/℃) C6 (± 10ppm/℃) C5 (± 15ppm/℃) C3 (± 25ppm/℃) C2 (± 50ppm/℃) relative to C10 (2ppm/℃), C9 (3ppm/℃), C7 (5ppm/℃), C6 (10ppm/℃), C5 (15ppm/℃) Note: 1. Absolute value refers to independent parameters (resistance value deviation or temperature coefficient) of all component resistors in the network; 2. The relative value refers to the maximum difference of this parameter between the component resistors in the same network; 3. The temperature range of temperature coefficient test is 25 ℃~85 ℃, and those beyond the test temperature range can be supplied through negotiation. Applicable standards
