The recommended mounting method for the ON1525E is to use a screw or clip mount to ensure good thermal contact and mechanical stability. Ohmite recommends using a torque of 10-15 in-lbs (1.1-1.7 Nm) for screw mounting.
Yes, the ON1525E is designed to withstand high-vibration environments. Ohmite tests their resistors to ensure they can withstand vibrations up to 10G (10 times the acceleration due to gravity) in accordance with IEC 60068-2-6.
The ON1525E has a maximum operating temperature of 250°C (482°F). While it can handle high temperatures, it's essential to derate the power according to the temperature derating curve provided in the datasheet to ensure reliable operation.
The ON1525E has a moisture sensitivity level (MSL) of 1, which means it can withstand normal humidity levels. However, it's not designed for immersion in water or exposure to high humidity environments. If used in humid environments, ensure proper sealing and conformal coating to prevent moisture ingress.
The expected lifespan of the ON1525E depends on various factors, including operating temperature, power rating, and environmental conditions. Ohmite estimates a minimum lifespan of 10,000 hours at 70°C (158°F) and 50% power rating. However, this can vary depending on the specific application and usage.
