TWW10J4R7E - Ohmite

TWW10J4R7E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the TWW10J4R7E?
  The thermal resistance of the TWW10J4R7E is typically around 10°C/W, but this can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's technical support or refer to the manufacturer's application notes for more information.
• Is the TWW10J4R7E resistor suitable for high-frequency applications?
  The TWW10J4R7E is a wirewound resistor, which can exhibit inductive behavior at high frequencies. While it can be used in high-frequency applications, it's not the most ideal choice. Ohmite recommends using their non-inductive resistors, such as the TNPW series, for high-frequency applications above 100 kHz.
• Can the TWW10J4R7E be used in high-vibration or high-shock environments?
  The TWW10J4R7E is designed to meet the requirements of MIL-PRF-39007, which includes vibration and shock testing. However, it's essential to consult with Ohmite's technical support to ensure the resistor can meet the specific vibration and shock requirements of your application.
• What is the recommended soldering temperature and time for the TWW10J4R7E?
  Ohmite recommends soldering the TWW10J4R7E at a temperature of 260°C (500°F) for 3-5 seconds. It's essential to follow the manufacturer's recommended soldering profile to prevent damage to the resistor.
• Is the TWW10J4R7E resistor RoHS and REACH compliant?
  Yes, the TWW10J4R7E resistor is RoHS and REACH compliant, meeting the requirements of the European Union's directives on the restriction of hazardous substances in electrical and electronic equipment.
