EVRT252EP2R2JE - Ohmite

EVRT252EP2R2JE Frequently Asked Questions (FAQs)

• What is the recommended soldering temperature and time for the EVRT252EP2R2JE?
  Ohmite recommends a soldering temperature of 260°C (500°F) for 3-5 seconds. However, it's essential to consult the specific soldering process guidelines for your application and ensure compatibility with the resistor's materials.
• Can I use the EVRT252EP2R2JE in high-vibration or high-shock environments?
  While the EVRT252EP2R2JE is a ruggedized resistor, it's still important to consult Ohmite's vibration and shock testing data to ensure the component meets your specific application requirements. Additional testing or customization may be necessary for extreme environmental conditions.
• How does the EVRT252EP2R2JE perform in high-temperature applications, such as in automotive or industrial environments?
  The EVRT252EP2R2JE is rated for operation up to 155°C (311°F). However, Ohmite provides derating guidelines for high-temperature applications. It's crucial to consult these guidelines and consider the resistor's power rating, thermal management, and potential degradation over time.
• What is the expected lifespan of the EVRT252EP2R2JE under normal operating conditions?
  Ohmite estimates the EVRT252EP2R2JE's lifespan to be in excess of 10,000 hours under normal operating conditions (70°C, 50% rated power). However, this can vary depending on factors like environmental conditions, power cycling, and application-specific stresses.
• Can I use the EVRT252EP2R2JE in high-humidity or moisture-rich environments?
  The EVRT252EP2R2JE is designed to meet the requirements of IPC/JEDEC J-STD-020D.1 for moisture sensitivity. However, it's still important to follow proper handling, storage, and assembly procedures to prevent moisture-related issues. Consult Ohmite's guidelines for humid or moisture-rich environments.
