Specification Item Resistor Jumper Test methods Resistance to soldering heat ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be dipped in the melted solder bath at 270 °C ± 5 °C for 10s ± 1s. Vibration ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be subjected to a single vibration having as double amplitude of 1.5 mm for 2 hours in each three mutually perpendicular directions for total 6 hours. The vibration frequency shall be varied uniformly 10 Hz to 55 Hz and return to 10 Hz traversing for 1 minute. Without distinct deformation in appearance Solvent resistance ±(0.5 %+0.05 Ω) Less than 50 m Ω Solvent solution: Isopropyl alcohol (1) Dipping 10 hours ± 1 hour, dry in room condition for 30 min ± 10 min. (2) Ultrasonic wave washing: 5 min ± 1 min (0.3 W/cm,28 kHz) Dry in room condition for 30 min ± 10 min. 8. Environmental Test Specification Item Resistor Jumper Test methods Low temperature exposure ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be exposed at -55 °C ± 3 °C for 1000 hours hours Low temperature operating ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be placed at -65 °C ± 5 °C for 1.5hours. After applying RCWV for 45 minutes, resistors shall be exposed in room condition for 8 hours ± 1 hour. Endurance at upper category temperature ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be exposed at +125 °C±3 °C for 1000 hours hours. Temperature cycling ±(1 %+0.05 Ω) Less than 50 m Ω -55 °C ± 3 °C, 30 minutes ↑↓ Nominal temp., 30minutes 25cycles ↑↓ +125 °C ± 3 °C, 30minutes Humidity (Steady state) ±(1 %+0.05 Ω) Less than 50 m Ω Resistors shall be exposed at 60 °C ± 2 °C and 90 % to 95 % relative humidity in a humidity test chamber for 1000 hours hours. Salt spray ±(1 %+0.05 Ω) Less than 50 m Ω Spray 5 wt% ± 1 wt% salt water for 96 hours ± 4 hours at 35 °C ± 2 °C Endurance at 70 °C ±(3 %+0.1 Ω) Less than 50 m Ω Resistors shall be exposed at 70 °C ± 2 °C for 1000 hours hours. During this time, the rated voltage shall be applied intermittently for 1.5 hours ON, 0.5 hour OFF.
