The recommended soldering temperature is 260°C (500°F) with a maximum dwell time of 10 seconds. It's essential to follow the soldering profile recommended by Cornell Dubilier to ensure the capacitor's reliability and performance.
Yes, the 103MMR400K is designed to withstand high-vibration environments. It meets the vibration test requirements of IEC 60068-2-6, which involves sinusoidal vibration at 10-2000 Hz with an amplitude of 1.5 mm. However, it's crucial to ensure proper mounting and secure the capacitor to prevent mechanical stress.
The 103MMR400K is designed to operate in humid environments. It meets the humidity test requirements of IEC 60068-2-78, which involves exposure to 85°C (185°F) and 85% relative humidity for 1000 hours. However, it's essential to ensure proper sealing and conformal coating to prevent moisture ingress.
No, the 103MMR400K is rated for operation up to 125°C (257°F). Exceeding this temperature can lead to reduced performance, reliability, and lifespan. If you need a capacitor for high-temperature applications, consider Cornell Dubilier's high-temperature capacitor series, such as the 103MMH or 103MMI.
Cornell Dubilier recommends derating the 103MMR400K capacitor by 20% for operating temperatures above 85°C (185°F) and 10% for operating voltages above 80% of the rated voltage. This ensures reliable operation and prevents premature failure.
