4 / 12 page SPECIFICATION No. JVR03Z-7148B 4/12 UNCONTROLLED COPY REFERENCE ONLY AC Amplifier Oscilloscope Proofread Resistance Constant Current Source (Test current shown in below) Rx #1 #2 #3 RX:Trimmer Potentiometer 5. Test Method 5.1 Contact resistance variation (CRV) Contact resistance variation should be measured with the measuring circuit shown below, or its equivalent. The operating wiper should be rotated in both directions through 90% of the actual effective electrical travel for a total of 6 cycles. The rate of rotation of the operating wiper should be such that the wiper completes 1 count in determining whether or not a contact resistance variation is observed at least twice in the same location. [Measurement circuit] [Measurement wave] [Test current for CRV] IS : Test current for CRV RX: Nominal total resistance of trimmer potentiometer VN: Noise voltage (peak to peak) 5.2 Temperature coefficient of resistance The trimmer potentiometer should be subjected to each of the following temperatures (see Table 1) for 30 to 45 minutes. The resistance value should be measured in the chamber. R2 - R1 TC = X 10 6 (ppm/°C) R1 (T2 - T1) 5.3 Permitted force of Driver plate A static load of 4.9N (Ref; 500gf) should be applied on the driver plate of the trimmer potentiometer for 5+1/-0 second. The load should be applied on driver plate uniformly by the 3mm-size plate of push-pull gage. 5.4 Soldering strength The trimmer potentiometer should be soldered under the soldering condition described in paragraph 7.2(1) on standard land pattern described in 9. Outline dimensions. A static load of 9.8N (Ref; 1kgf) should be applied from rear side through the hole opened in the center of PCB by the 1.0±0.1mm dia. stick for 5 second. VN Except ineffective variable portion Nominal total resistance Test current 220 ohm<=R< 10k ohm 10k ohm<=R<100k ohm 100k ohm<=R 10mA max. 1mA max. 100 µA max. Table 1 Sequence *1 2 *3 4 Temp.

VN CRV = 100(%) IS • RX T1 : Reference temperature in degrees Celsius T2 : Test temperature in degrees Celsius R1 : Resistance at reference temperature in ohm R2 : Resistance at test temperature in ohm The tests and measurements should be conducted under the condition of 15 to 35°C of temperature, 25 to 75% of relative humidity and 86 to 106 kpa of atmospheric pressure unless otherwise specified. If questionable results occur that have been measured in accordance with the above mentioned conditions, the tests and measurements should be conducted under the condition of 25±2°C of temperature and, 45 to 55% of relative humidity and 86 to 106 kpa of atmospheric pressure. When the trimmer potentiometer is tested after soldering on PCB, it should be tested after being kept in a room (15 to 35°C, 25 to 75%RH) over 24 hours except ” 5.12 Resistance to soldering heat“. |
