Coilcraft recommends a land pattern with a pad size of 2.2 mm x 1.1 mm, with a non-solder mask defined (NSMD) pad and a 0.2 mm gap between pads. This ensures proper soldering and minimizes the risk of solder bridging.
The SER2211-822MED is rated for operation up to 125°C, but derating is required above 85°C. Consult the datasheet for derating curves and ensure that your design meets the recommended operating conditions.
To minimize electromagnetic interference (EMI), keep the inductor at least 2 mm away from sensitive components and consider using a shield or a metal layer to contain the magnetic field. You can also use simulation tools to model the magnetic field and optimize your design.
The SRF of the SER2211-822MED is approximately 250 MHz. This means that the inductor will start to behave like a capacitor above this frequency, which can affect its performance in your design.
The SER2211-822MED is rated for a maximum current of 2.2 A. Exceeding this rating can cause the inductor to overheat, leading to reduced performance and lifespan. Ensure that your design stays within the recommended current limits.
