The recommended PCB land pattern for the 4221-2 is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder mask defined (NSMD) pad shape.
To minimize the risk of moisture-related failures, store the 4221-2 in a dry, cool place, and follow the recommended baking and drying procedures before soldering.
The maximum allowable voltage for the 4221-2 is 100 V, although the recommended operating voltage is 50 V to ensure optimal performance and reliability.
The 4221-2 is rated for operation up to 125°C, but derating is recommended for temperatures above 85°C to ensure reliability and prevent thermal runaway.
To ensure the 4221-2 meets your application's EMI requirements, consider using shielding, filtering, and proper PCB layout techniques to minimize electromagnetic interference.
