TWW5J3R0E Frequently Asked Questions (FAQs)

  • The thermal resistance of the TWW5J3R0E is not explicitly stated in the datasheet, but according to Ohmite's general specifications for the TWW series, the thermal resistance is typically around 10-15°C/W.
  • While the TWW5J3R0E is a wirewound resistor, it's not specifically designed for high-frequency applications. Ohmite recommends their thin-film resistors for high-frequency use. However, the TWW5J3R0E can still be used in lower-frequency applications up to a few hundred kHz.
  • The TWW5J3R0E is a wirewound resistor with a rugged construction, making it suitable for use in high-vibration environments. However, it's essential to ensure proper mounting and secure the resistor to prevent mechanical stress.
  • Yes, the TWW5J3R0E is RoHS compliant, meaning it meets the European Union's Restriction of Hazardous Substances directive. Ohmite ensures that their products comply with RoHS regulations.
  • Ohmite recommends a soldering temperature of 260°C (500°F) for the TWW5J3R0E. It's essential to follow proper soldering techniques and temperature control to prevent damage to the resistor.
