The thermal resistance of the EV-T220-64E 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 levels. However, it's recommended to consult with Ohmite's technical support or perform additional testing to ensure the resistor's reliability in your specific high-vibration application.
The EV-T220-64E is a wirewound resistor, which may not be the best choice for high-frequency applications due to potential inductance and self-resonance issues. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
The EV-T220-64E has a moisture sensitivity level (MSL) of 1, which means it can withstand normal humidity levels. However, it's still important to follow proper storage and handling procedures to prevent moisture ingress. If your application involves extreme humidity or moisture, consider using a resistor with a higher MSL rating or additional protective measures.
According to Ohmite's soldering guidelines, the recommended soldering temperature is 260°C (500°F) with a maximum soldering time of 3 seconds. It's essential to follow these guidelines to prevent damage to the resistor or its termination.
