RN55D7502FB14 datasheet by Vishay Dale

RN55D7502FB14 Frequently Asked Questions (FAQs)

• What is the thermal resistance of the RN55D7502FB14?
  The thermal resistance (Rth) of the RN55D7502FB14 is approximately 250°C/W, which means it can dissipate 1W of power without exceeding the maximum operating temperature.
• Is the RN55D7502FB14 suitable for high-frequency applications?
  While the RN55D7502FB14 is a general-purpose resistor, it's not optimized for high-frequency applications. For frequencies above 100 kHz, it's recommended to use specialized high-frequency resistors with lower inductance and capacitance.
• Can I use the RN55D7502FB14 in a high-temperature environment?
  The RN55D7502FB14 has a maximum operating temperature of 155°C. While it can tolerate high temperatures, it's essential to derate the power according to the temperature derating curve in the datasheet to ensure reliable operation.
• How do I handle the RN55D7502FB14 for soldering and assembly?
  The RN55D7502FB14 is a lead-free, RoHS-compliant component. Follow standard soldering practices, and ensure the component is handled in a static-safe environment to prevent damage from electrostatic discharge (ESD).
• What is the recommended land pattern for the RN55D7502FB14?
  The recommended land pattern for the RN55D7502FB14 can be found in the Vishay Intertechnologies' datasheet or in the IPC-7351 standard. A properly designed land pattern ensures reliable solder joints and prevents thermal and mechanical stress.
