The recommended PCB land pattern can be found in the Sumida Corporation's application note or by contacting their technical support. A general guideline is to use a land pattern with a minimum of 1.5 mm x 1.5 mm pad size and a 0.5 mm x 0.5 mm thermal pad.
The thermal derating of the CDRH6D28NP-820NC is typically handled by reducing the maximum current rating as the ambient temperature increases. A general guideline is to reduce the current rating by 1.5% per degree Celsius above 40°C. Consult the datasheet or contact Sumida Corporation's technical support for more information.
The self-resonant frequency (SRF) of the CDRH6D28NP-820NC is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance value and the parasitic capacitance. As a rough estimate, the SRF can be around 100-200 MHz. For more accurate information, contact Sumida Corporation's technical support.
While the CDRH6D28NP-820NC is designed for high-frequency applications, its performance may degrade above 100 MHz. It's essential to evaluate the inductor's impedance and loss characteristics at the desired frequency to ensure it meets the application's requirements. Consult the datasheet and contact Sumida Corporation's technical support for more information.
To ensure the reliability and longevity of the CDRH6D28NP-820NC, follow proper storage and handling procedures, avoid exceeding the maximum ratings, and ensure the PCB design and assembly meet the recommended guidelines. Additionally, consider implementing a robust design with adequate margins, and perform thorough testing and validation.
