Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure optimal performance, low EMI, and high reliability.
To minimize the impact of SRF, ensure the operating frequency is below the SRF, and use proper PCB layout techniques to reduce parasitic capacitance. You can also consider using a different inductor with a higher SRF or adding a decoupling capacitor to mitigate the effect.
The maximum allowable current is dependent on the inductor's temperature rating. For the SRU8043-100Y, the maximum current rating is 10.4A at 40°C. Exceeding this current may lead to overheating, reducing the inductor's lifespan. Always check the temperature derating curve in the datasheet to ensure safe operation.
The SRU8043-100Y is rated for operation up to 125°C. However, the inductor's performance and lifespan may degrade at higher temperatures. Always check the temperature derating curve and consider the application's specific requirements before using the inductor in high-temperature environments.
The DCR of the SRU8043-100Y is 0.025Ω. To minimize power losses, consider the DCR when designing your circuit, especially in high-current applications. You can also use the DCR to estimate the inductor's power dissipation and temperature rise.
