TKH45P100RFE-TR Frequently Asked Questions (FAQs)

  • The thermal resistance of the TKH45P100RFE-TR is not explicitly stated in the datasheet, but it can be estimated to be around 10-15°C/W, which is typical for a thick-film resistor of this size and material.
  • While the TKH45P100RFE-TR is a general-purpose resistor, it may not be the best choice for high-frequency applications due to its thick-film construction, which can introduce parasitic inductance and capacitance. For high-frequency applications, a thin-film or metal-film resistor may be a better option.
  • The TKH45P100RFE-TR has a maximum operating temperature of 155°C, but it's recommended to derate the power rating at higher temperatures to ensure reliability. Consult the datasheet for derating curves and consult with Ohmite Mfg Co for specific guidance.
  • Yes, the TKH45P100RFE-TR is compatible with lead-free soldering processes, as it is RoHS-compliant and meets the requirements of the EU's Restriction of Hazardous Substances (RoHS) directive.
  • The recommended land pattern for the TKH45P100RFE-TR can be found in the datasheet or on Ohmite Mfg Co's website. It's essential to follow the recommended land pattern to ensure reliable soldering and to prevent thermal and mechanical stress on the component.
