CDRH4D28-100NC Details

A recommended PCB layout for the CDRH4D28-100NC would be to use a 4-layer board with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke or a ferrite bead to filter out high-frequency noise.
To ensure reliability in high-temperature applications, it's recommended to derate the output current of the CDRH4D28-100NC according to the temperature derating curve provided in the datasheet. Additionally, ensure good airflow around the component and consider using a heat sink if necessary.
The maximum allowable voltage drop across the CDRH4D28-100NC is 100mV. Exceeding this voltage drop may affect the performance and reliability of the component.
Yes, the CDRH4D28-100NC can be used in a parallel configuration to increase the output current. However, it's recommended to ensure that the components are matched in terms of output voltage and current to prevent uneven current sharing.
The recommended input capacitor value for the CDRH4D28-100NC is 10uF to 22uF, with a voltage rating of at least 25V. A larger capacitor value may be required for high-ripple current applications.
