Bourns recommends a soldering temperature profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds, with a ramp-up rate of 3°C/s (5.4°F/s) and a ramp-down rate of 6°C/s (10.8°F/s).
While the CR0805-FX-8450ELF is a general-purpose chip resistor, it may not be the best choice for high-frequency applications (>100 MHz) due to its relatively high inductance and parasitic capacitance. For high-frequency applications, consider using a resistor with a more suitable construction, such as a thin-film or metal foil resistor.
The CR0805-FX-8450ELF has a maximum operating temperature of 150°C (302°F). While it can tolerate short-term excursions up to 200°C (392°F), prolonged exposure to high temperatures may affect its performance and reliability. If your application requires operation above 150°C, consider using a resistor with a higher temperature rating.
To ensure optimal reliability, handle the CR0805-FX-8450ELF resistor by the body, avoiding touching the termination pads or the resistor element. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. Store the resistors in their original packaging or in a dry, cool place, away from direct sunlight and moisture.
The CR0805-FX-8450ELF has a moisture sensitivity level (MSL) of 2, which means it can withstand normal humidity levels. However, exposure to high humidity or moisture may affect its performance and reliability. If your application involves high humidity or moisture, consider using a resistor with a higher MSL rating or applying conformal coating or other environmental protection measures.
