Coilcraft recommends a land pattern with a minimum pad size of 1.4 mm x 1.4 mm and a non-solder mask defined (NSMD) pad shape to ensure reliable assembly and minimize thermal resistance.
The MSD1514-123MED is rated for operation up to 125°C, but derating is required above 85°C. Consult the datasheet for specific derating curves and ensure your design meets the recommended operating conditions.
To minimize magnetic field interference, keep the inductor at least 2-3 mm away from sensitive components, such as oscillators or magnetically sensitive devices. You can also use shielding or mu-metal to contain the magnetic field.
The SRF of the MSD1514-123MED is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance.
The MSD1514-123MED is rated for a maximum current of 1.23 A. Exceeding this rating can cause overheating, reduced lifespan, or even failure. Ensure your design stays within the recommended current limits.
