Shops resistance R40102 intended for use as a multi-valued measures electrical resistance in DC circuits. Operating conditions according to Table stores. 1. Climatic performance UHL4.1 according to GOST 15150-69.
Main parameters and codes OKP R40102 stores are listed in Table. 2. Maximum Power dissipation at nominal level are given in Table. 2. Limit of acceptable deviation of the actual value of the resistance of the nominal R40102 stores, the percentage does not exceed the class of accuracy under normal conditions of use:
ambient temperature (20 ± 0,5) ° C, relative humidity of 25 to 80%, atmospheric pressure 84-106.7 kPa (630-800 mm Hg), the constant current, voltage or power is not over rated (Table 2).
The limit of additional error shops R40102 induced changes in ambient temperature between the upper (lower) limit the range of normal conditions of use and by some point in the related field of application of the operating temperature corresponding to the maximum change in R max, is 0.02%.
The limit of additional error store R40102 voltage changes at the store from its nominal value to any value that does not exceed the maximum, under normal conditions of use and steady-state thermal equilibrium is 0.02%.
Shops are a group of 2, type 1 according to GOST 27.003-83, restored, repaired, Single function.
Norma MTBF with the maintenance of the regulated operational documentation 12500 hrs
MTBF is set for the working conditions and the voltage (power) of 0.5 nominal. The criterion of failure is the mismatch of shops R40102 requirements by value limit of acceptable deviation (above). The mean time to repair the state store 4 hours full average life of shops 10 years.
Installed failure operating time for the working conditions and the maximum voltage (power) applied to 1000 parts store
The criterion of failure is the mismatch of shops R40102 requirements by value limit of acceptable deviation (above). Specified service life of shops 3 years. The silver content in the stores, the R40102 -9.24
* When at least 6 steps - for decades "x 10 6 ohms" and 4 steps - for decades "x 10 7 ohm"
