Additional Technical Details
Operating Temperature Range: -65175
Construction:
- Base: Alkali-free heat-resistant ceramic rod.
- Terminals: Tin-plated soft copper wire for electrical use.
- Coating: Insulating or non-combustible coating (heat resistant to 800), firm and not easily peeled off.
- Marking: 5 distinct color bands on the resistor body. The first 4 bands indicate resistance value, and the 5th band indicates tolerance.
Mechanical Performance:
- Tensile Strength: 1kg applied axially to one terminal for 10 seconds without detachment or looseness.
- Terminal Torsional Strength: Tested by bending and rotating terminals without breakage or looseness.
Electrical Performance:
- Temperature Coefficient: Specified codes (T-1, T-2, T-9) correspond to 100ppm/, 50ppm/, 25ppm/ respectively.
- Temperature Cycling: Resistance change rate within 0.25% after 5 cycles between -65 and 175.
- Short-Time Overload: Withstands 2.5 times rated voltage for 5 seconds, resistance change rate within 0.5% after cooling.
- Dielectric Strength: Withstands specified AC voltages for 1 minute without abnormality or burnout.
- Insulation Resistance: 10000M at DC 500V.
- Damp Heat Life: Resistance change rate within 1.5% after 1000 hours at 402, 90-95% RH with cyclic loading.
- Load Life: Resistance change rate within 2% after 1000 hours at 70 with cyclic loading.
- Solderability: Solder coverage 95% of terminal area after immersion in 2355 tin bath for 2 seconds.
- Solder Heat Resistance: Resistance change rate within 0.5% after immersion in specified tin baths and cooling.
Packaging and Processing:
- Taped Packaging (T-26, T-52, T-63): Various dimensions and quantities per reel based on wattage.
- Boxed Packaging (T-26, T-52, T-63): Quantities per box vary by wattage.
- M Type Processing (M1, M2, M3): Specific dimensions for processed forms, applicable to certain wattages.
Usage Precautions: For resistance values exceeding 100K, use below 50V when ambient temperature and humidity are above 85/85% to prevent galvanic corrosion.
