automatic handling machines
• ^{Compatible with flow and re-flow soldering methods}
SPECIFICATIONS
Resistance Range: 10 Ohms to 1.0 M Ohms in E 24 Series. (Please
also see Power Ratings Table. )
Rated Power: 1/16 to 1/4W. (Please also see Power Ratings Table. )
Rated Voltage: Rated Power x Nominal Resistance.
Overload Voltage: Please refer to Rated Voltage Table.
Temperature Coefficient: ± 250 ppm per °C.
Temperature Range: -55°C to +125°C with derating above 70°C
Tolerance: ± 5% ( ±1% On request.).
Load Life:
The component will be subjected to 1000 hours of testing at rated
voltage and 70° C, with duty cycles of 1.5 hours ''on'' and 0.5 hours ''off''.
After the test the Resistance change will remain within ±3% of the initial
value + 0.1 Ohm for values above 1 M Ohm and 5% for values less than
1 M Ohm.
Resistance to Soldering Heat:
The component can be subjected to a soldering temperature of 270 °C
for 10 seconds. After the test the Resistance change will remain within
±3% + 0.1 Ohms.
Tolerance on Dimensions:
''L'' and ''W'': ± 0.25mm(0.01'')
