TUM5J10KE - Ohmite

TUM5J10KE Frequently Asked Questions (FAQs)

• What is the thermal resistance of the TUM5J10KE?
  The thermal resistance of the TUM5J10KE is not explicitly stated in the datasheet, but it can be estimated to be around 10-15°C/W, considering the device's power rating and package type.
• Can I use the TUM5J10KE in a high-frequency application?
  While the TUM5J10KE is a wirewound resistor, it's not designed for high-frequency applications. The inductive reactance of the wirewound design can cause significant impedance at high frequencies, making it unsuitable for such applications.
• Is the TUM5J10KE suitable for high-pulse applications?
  The TUM5J10KE is designed to handle high-pulse applications, but the datasheet doesn't provide explicit pulse-handling capabilities. However, Ohmite's general guidelines for pulse handling suggest that this device can handle pulses up to 10 times the rated power for short durations (typically < 1 second).
• What is the recommended PCB layout for the TUM5J10KE?
  The datasheet doesn't provide specific PCB layout recommendations, but general guidelines for wirewound resistors suggest keeping the component away from other heat sources, using a thermal pad or heat sink if possible, and ensuring good airflow around the device.
• Can I use the TUM5J10KE in a high-vibration environment?
  The TUM5J10KE is a wirewound resistor, which can be prone to vibration-induced failures. While Ohmite doesn't provide explicit vibration ratings, it's recommended to consider alternative resistor types (e.g., thick-film or thin-film) that are more resistant to vibration.
