SRR0735A-220M Details

Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the component away from high-frequency noise sources. A minimum of 2 oz copper thickness is recommended for the PCB.
While the datasheet specifies an operating temperature range of -40°C to +125°C, Bourns recommends derating the component's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
Bourns recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a ramp rate of 3°C/second to prevent thermal shock and ensure reliable solder joints.
Yes, the SRR0735A-220M is designed to withstand vibrations up to 10 G peak acceleration, but Bourns recommends additional mechanical support or potting to ensure reliability in extreme vibration environments.
Bourns estimates a typical lifespan of 10-15 years under normal operating conditions, but this can vary depending on factors such as operating temperature, current, and environmental conditions.
