Vishay provides a recommended PCB pad layout in their application note AN2002, which can be found on their website. The recommended pad layout is also available in the IHLP4040DZER datasheet.
To minimize the effects of the high self-resonant frequency, it is recommended to use a series resistor or a damping resistor to reduce the Q factor. Additionally, the inductor can be used in a configuration that minimizes the effects of resonance, such as in a pi-filter or a common-mode choke.
The IHLP4040DZER is rated for operation up to 155°C, but derating is required for temperatures above 125°C. Consult the datasheet for derating information and ensure that the inductor is used within its specified operating temperature range.
Vishay provides EMI shielding options for the IHLP4040DZER, such as the IHLP4040DZER-01, which has a built-in shield. Additionally, the inductor can be used in conjunction with other EMI mitigation techniques, such as shielding cans or EMI-absorbing materials.
Vishay recommends storing the IHLP4040DZER in a dry, cool place, away from direct sunlight and moisture. The inductor should be handled with care to avoid mechanical stress, and electrostatic discharge (ESD) precautions should be taken to prevent damage.
