CRCW25128K20JNEG - Vishay

CRCW25128K20JNEG Frequently Asked Questions (FAQs)

• What is the thermal resistance of the CRCW25128K20JNEG?
  The thermal resistance of the CRCW25128K20JNEG is not explicitly stated in the datasheet, but it can be estimated to be around 250-300°C/W, which is a typical value for a 2512-sized thick-film resistor.
• Is the CRCW25128K20JNEG suitable for high-frequency applications?
  The CRCW25128K20JNEG is a thick-film resistor, which may not be the best choice for high-frequency applications due to its higher parasitic inductance and capacitance compared to thin-film resistors. However, it can still be used up to a few hundred MHz with proper PCB design and layout considerations.
• Can I use the CRCW25128K20JNEG in a high-temperature environment?
  The CRCW25128K20JNEG has a maximum operating temperature of 155°C, but it can be derated for higher temperatures. However, it's recommended to consult with Vishay's application engineers or perform thorough testing to ensure the resistor's reliability and stability in extreme temperature conditions.
• Is the CRCW25128K20JNEG compatible with lead-free soldering processes?
  Yes, the CRCW25128K20JNEG is compatible with lead-free soldering processes, as it is a RoHS-compliant component. However, it's essential to follow the recommended soldering profile and temperature guidelines to ensure reliable assembly and minimize the risk of damage or failure.
• What is the recommended land pattern for the CRCW25128K20JNEG?
  The recommended land pattern for the CRCW25128K20JNEG can be found in the Vishay Intertechnologies' application note 'Land Pattern Recommendations for Vishay Resistors' (document number: 31011). It's essential to follow these guidelines to ensure proper assembly and minimize the risk of thermal or mechanical stress on the component.
