R2A-CT2-38E - Ohmite

R2A-CT2-38E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the R2A-CT2-38E?
  The thermal resistance of the R2A-CT2-38E is not explicitly stated in the datasheet, but according to Ohmite's general specifications for the R2A series, the thermal resistance is typically around 10-15°C/W.
• Is the R2A-CT2-38E suitable for high-frequency applications?
  While the R2A-CT2-38E is a general-purpose resistor, it's not optimized for high-frequency applications. Ohmite recommends their HF series resistors for high-frequency uses. However, the R2A-CT2-38E can still be used up to a few hundred kHz with minimal signal attenuation.
• Can I use the R2A-CT2-38E in a high-vibration environment?
  The R2A-CT2-38E is a through-hole resistor with a robust design, but it's not specifically designed for high-vibration environments. However, Ohmite's resistors are generally built to withstand moderate vibrations. If you expect extreme vibrations, consider using a resistor with a more rugged design, such as Ohmite's V Series.
• Is the R2A-CT2-38E compatible with lead-free soldering?
  Yes, the R2A-CT2-38E is compatible with lead-free soldering. Ohmite's resistors are RoHS compliant and can be soldered using lead-free soldering techniques.
• What is the recommended power derating for the R2A-CT2-38E?
  The recommended power derating for the R2A-CT2-38E is typically 50-70% of the maximum power rating, depending on the ambient temperature and airflow. This ensures reliable operation and prevents overheating.
