- Operating Temperature Range: -55°C ~ 155°C
- Power Derating: For ambient temperatures exceeding 70°C, the load must be derated in accordance with the power derating curve to ensure optimal performance and longevity.
The specialized material and structural design of the HR1206 series enable it to withstand high working voltages and overload voltages, making it suitable for high-voltage electronic circuits where reliability under extreme conditions is paramount.
With tight T.C.R. control (±100 ppm/°C for
most resistance ranges), the resistor maintains stable resistance values across a wide temperature range, minimizing performance fluctuations caused by temperature changes in various operating environments.
Rigorous reliability tests confirm the HR1206 series' durability:
- Short Time Overload: Withstands 2.5 times the rated continuous working voltage (RCWV) or maximum overload voltage (whichever is lower) for 5 seconds, with resistance change ≤±2.0% (TYPE-2)
- Resistance to Soldering Heat: Exposed to 260±5°C for 10 seconds, resistance change ≤±1.0%
- Rapid Temperature Change: Endures 5 cycles of -55°C to +155°C, resistance change ≤±1.0%
- Damp Heat with Load: Operates at 40±2°C, 90~95% relative humidity for 1000 hours (1.5 hours ON/0.5 hours OFF) with resistance change ≤±3.0%
- Load Life (Endurance): Works at 70±2°C for 1000 hours (1.5 hours ON/0.5 hours OFF) with resistance change ≤±3.0%
Compliant with standard SMD packaging, the HR1206 series features precise dimensions and compatible land pattern design, facilitating seamless integration into automated assembly processes, improving production efficiency, and reducing assembly errors.
