The thermal resistance of the TCH35P2R20JE is not explicitly stated in the datasheet, but it can be estimated to be around 10-15°C/W, which is typical for a 35W resistor of this size.
While the datasheet doesn't explicitly mention vibration resistance, Ohmite resistors are generally designed to withstand moderate vibration. However, it's recommended to consult with Ohmite's application engineers to determine the suitability of the TCH35P2R20JE for your specific vibration-prone application.
The TCH35P2R20JE is a commercial-grade resistor, but it's not specifically designed for high-reliability applications. If you need a resistor for a high-reliability application, you may want to consider Ohmite's military-grade or high-reliability resistors, which are designed to meet more stringent requirements.
The TCH35P2R20JE has a moisture sensitivity level (MSL) of 1, which means it can withstand normal humidity levels. However, if you plan to use it in an extremely humid environment, you may need to take additional precautions, such as conformal coating or potting, to ensure the resistor's reliability.
The recommended PCB footprint for the TCH35P2R20JE is not explicitly stated in the datasheet. However, a general guideline is to use a footprint with a minimum pad size of 0.25 inches (6.4 mm) in diameter, with a 0.05-inch (1.3 mm) spacing between pads.
