KDV12FR270ET - Ohmite

KDV12FR270ET Frequently Asked Questions (FAQs)

• What is the thermal resistance of the KDV12FR270ET?
  The thermal resistance of the KDV12FR270ET is typically around 10°C/W, but this value can vary depending on the specific application and mounting method.
• Is the KDV12FR270ET resistor suitable for high-frequency applications?
  The KDV12FR270ET is a wirewound resistor, which can exhibit significant inductance at high frequencies. It's not recommended for high-frequency applications above 100 kHz. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
• Can I use the KDV12FR270ET in a high-vibration environment?
  The KDV12FR270ET is designed to withstand moderate vibration, but it's not recommended for extreme vibration environments. If you need a resistor for a high-vibration application, consider using a resistor with a more robust construction, such as a ceramic or metal-cased resistor.
• Is the KDV12FR270ET resistor RoHS compliant?
  Yes, the KDV12FR270ET resistor is RoHS (Restriction of Hazardous Substances) compliant, meaning it meets the European Union's directive on the restriction of certain hazardous substances in electrical and electronic equipment.
• What is the recommended derating curve for the KDV12FR270ET?
  The recommended derating curve for the KDV12FR270ET can be found in the Ohmite Mfg Co datasheet or application notes. As a general rule, it's recommended to derate the resistor's power rating by 1-2% per degree Celsius above the rated temperature of 70°C.
