Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure proper mounting and to minimize parasitic inductance.
Bourns offers different variants of the CDNBS08-T08C with varying inductance values and current ratings. To select the correct variant, consider factors such as the operating frequency, current requirements, and available board space. Consult with Bourns' application engineers or distributors for guidance if needed.
The SRF of the CDNBS08-T08C is not explicitly stated in the datasheet, but it can be estimated using the inductance and capacitance values. The SRF typically occurs at a frequency where the inductive reactance equals the capacitive reactance. Above the SRF, the inductor's impedance decreases, and it may not provide the desired filtering or impedance matching. Ensure your design operates below the SRF to maintain the desired performance.
The CDNBS08-T08C is rated for operation up to 125°C. However, the inductor's performance and reliability may degrade at higher temperatures. Consult the datasheet for derating factors, and consider using a thermally enhanced package or a different component if your application requires extended high-temperature operation.
The CDNBS08-T08C is designed to meet common EMI and EMC standards, but it's essential to consider the entire system design, including the PCB layout, component selection, and shielding. Ensure that your design meets the relevant EMI and EMC standards, and consult with Bourns' application engineers or EMC experts if needed.
