OK1055E - Ohmite

OK1055E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the OK1055E?
  The thermal resistance of the OK1055E is not explicitly stated in the datasheet. However, according to Ohmite's application notes, the thermal resistance of similar resistors in the OK series is around 10-15°C/W. It's recommended to consult with Ohmite's technical support for a more accurate value.
• Can the OK1055E be used in high-frequency applications?
  While the OK1055E is a wirewound resistor, it's not designed for high-frequency applications. The inductive nature of wirewound resistors can cause issues with high-frequency signals. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
• Is the OK1055E suitable for high-pulse applications?
  The OK1055E is designed to handle high-pulse applications, but it's essential to ensure that the pulse duration and frequency do not exceed the resistor's maximum ratings. Consult Ohmite's technical support to determine the resistor's suitability for your specific application.
• What is the recommended mounting method for the OK1055E?
  The OK1055E is typically mounted using a screw or clip. It's essential to ensure that the mounting method does not compromise the resistor's electrical connections or thermal performance. Consult Ohmite's application notes or technical support for recommended mounting methods.
• Can the OK1055E be used in high-temperature environments?
  The OK1055E has a maximum operating temperature of 250°C. While it can be used in high-temperature environments, it's essential to ensure that the resistor is properly derated to prevent overheating and premature failure. Consult Ohmite's technical support for guidance on derating and thermal management.
