The recommended land pattern for the RL875S-472K-RC can be found in the Bourns Application Note S-3081, which provides detailed information on land pattern design and layout considerations.
The RL875S-472K-RC has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management techniques such as heat sinking, air flow, and thermal interface materials to keep the inductor within its specified temperature range.
The self-resonant frequency (SRF) of the RL875S-472K-RC is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the SRF is around 100-200 MHz for this type of inductor.
While the RL875S-472K-RC is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's parasitic capacitance and resistance. It's essential to evaluate the inductor's behavior in your specific application and consider alternative components if necessary.
To ensure the RL875S-472K-RC meets your application's requirements, perform thorough simulations and testing, considering factors such as operating frequency, current, and temperature. Additionally, consult with Bourns' application engineers or seek guidance from experienced designers in your industry.
