Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, reduce electromagnetic interference, and optimize the inductor's performance.
The SRU2009-100Y is designed to minimize electromagnetic interference (EMI) and radio-frequency interference (RFI). Its shielded construction and internal Faraday shield help to reduce electromagnetic radiation and susceptibility.
Bourns recommends derating the voltage by 10-15% to ensure reliable operation and prevent overheating. This means that for a 100V rated inductor, the maximum allowable voltage would be around 85-90V.
The SRU2009-100Y is rated for operation up to 125°C. However, it's essential to consider the temperature coefficient of inductance and the potential for thermal runaway when operating in high-temperature environments.
Bourns recommends storing the SRU2009-100Y in a dry, cool place, away from direct sunlight and moisture. Handling should be done with electrostatic discharge (ESD) precautions, and the component should be kept away from mechanical stress and vibration.
