The recommended land pattern for CPF3470R00FKE14 can be found in the Vishay Intertechnologies' application note 'Land Pattern Recommendations for Vishay Resistive Products' (document number: 31011).
To prevent damage during soldering, it is recommended to follow the soldering guidelines outlined in the Vishay Intertechnologies' application note 'Soldering Guidelines for Vishay Resistive Products' (document number: 31012). This includes using a soldering iron with a temperature of 260°C to 280°C, and avoiding excessive soldering time.
The shelf life of the CPF3470R00FKE14 is typically 2 years from the date of manufacture, as long as it is stored in its original packaging and under recommended storage conditions (temperature: 20°C to 40°C, humidity: 60% to 90%).
While the CPF3470R00FKE14 is a general-purpose resistor, it is not recommended for high-frequency applications (>100 kHz) due to its construction and materials. For high-frequency applications, consider using specialized resistors designed for high-frequency use, such as those with a metal film or wirewound construction.
To determine the power rating of the CPF3470R00FKE14 at elevated temperatures, refer to the derating curve provided in the datasheet. The derating curve shows the maximum power rating at various temperatures, allowing you to determine the safe operating power at your specific application temperature.
