The thermal resistance of the EY271KE is not explicitly stated in the datasheet, but according to Ohmite's application notes, the thermal resistance (RθJA) is approximately 10°C/W for this specific model.
While the datasheet doesn't explicitly mention vibration tolerance, Ohmite's resistors are generally designed to withstand moderate vibration. However, it's recommended to consult with Ohmite's technical support or application engineers to determine the suitability of the EY271KE for your specific high-vibration application.
The EY271KE is a commercial-grade resistor, and its reliability and performance may not meet the stringent requirements of high-reliability or aerospace applications. Ohmite offers specialized resistors for these applications, such as their MIL-PRF-39007-compliant resistors. Consult with Ohmite's technical support to determine the best option for your specific application.
The EY271KE has a moisture sensitivity level (MSL) of 2, which means it can withstand normal humidity levels. However, exposure to excessive moisture or immersion in water may affect its performance and reliability. If your application involves high humidity or wet conditions, consider using a resistor with a higher MSL rating or consult with Ohmite's technical support for guidance.
The recommended soldering temperature for the EY271KE is 260°C (500°F) with a maximum soldering time of 3 seconds. However, it's essential to follow the soldering guidelines and recommendations provided by Ohmite or consult with their technical support to ensure proper assembly and reliability.
