Heat Dissipation: Although the use of proprietary heat sinks with lower thermal resistance is This high power density resistor is acceptable, up rating is not recommended. The use of proprietary heat sink made from quality materials for compound to improve thermal conductivity is essential. optimum reliability and stability with very low partial discharge. Characteristics - Tyco can test resistors to conform to relevant international, MIL or Environmental customer specifications, and will Endurance (Rated Power): Full Load, 1000h, 25°C ∆R 0.4% Typ advise on the use of resistors for pulse applications (special pulse Humidity Load Life: 56 Days, 40°C, 95% RH ∆R 0.25% Typ duty options available) and high Temperature Cycling: -55°C to +125°C, 5cycles ∆R 0.2% Typ voltage usage (high voltage designs Storage Temp: -55°C to +155°C available).
