CRL0603-FW-R270ELF - Bourns

CRL0603-FW-R270ELF Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this chip resistor?
  The recommended land pattern for the CRL0603-FW-R270ELF is a rectangular pad with a size of 0.6 mm x 0.3 mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Bourns application note 'Surface Mount Resistor Land Patterns'.
• Can I use this resistor in a high-temperature environment?
  The CRL0603-FW-R270ELF has a maximum operating temperature of 150°C. While it can tolerate high temperatures, it's essential to derate the power rating according to the temperature derating curve provided in the datasheet to ensure reliable operation.
• Is this resistor suitable for high-frequency applications?
  The CRL0603-FW-R270ELF is a general-purpose thick-film chip resistor, and its frequency response is not optimized for high-frequency applications. For high-frequency applications, consider using thin-film or metal-film resistors, which have better high-frequency characteristics.
• Can I use this resistor in a humid or moist environment?
  The CRL0603-FW-R270ELF has a moisture sensitivity level (MSL) of 1, which means it can withstand normal humidity levels. However, it's essential to follow proper handling and storage procedures to prevent moisture absorption, which can affect the resistor's reliability.
• What is the typical tolerance of this resistor?
  The CRL0603-FW-R270ELF has a tolerance of ±1% (F suffix). This means that the actual resistance value can vary by up to 1% from the nominal value of 270 ohms.
