A symmetrical layout with a ground plane underneath the inductor is recommended to minimize radiation and electromagnetic interference (EMI). Keep the PCB traces short and wide to reduce resistance and inductance.
Consider the converter's operating frequency, output current, and voltage ripple requirements. Choose an inductor with a suitable inductance value, saturation current, and DC resistance (DCR) to ensure efficient energy storage and transfer.
The LPS1100H47R0JB has a maximum operating temperature range of -40°C to +125°C. However, derating may be necessary for high-temperature applications to ensure reliability and prevent thermal runaway.
The SRF is typically above the operating frequency of most DC-DC converters. However, if the SRF is close to the operating frequency, consider adding a damping resistor or capacitor to prevent oscillations and ensure stable operation.
Store the inductors in a dry, cool place, away from direct sunlight and moisture. Handle them with care to prevent mechanical stress, which can cause damage or affect performance.
