The recommended PCB land pattern for the RLB0812-470KL can be found in the Bourns Application Note S-3083, which provides a detailed layout and footprint recommendation for optimal performance and reliability.
The RLB0812-470KL has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to provide adequate thermal relief, such as a thermal pad or via, and to follow proper PCB design and layout guidelines to minimize thermal resistance.
The self-resonant frequency (SRF) of the RLB0812-470KL is not explicitly stated in the datasheet. However, according to Bourns' application notes, the SRF of this inductor is typically above 100 MHz. For more accurate information, it's recommended to consult with Bourns' technical support or perform your own measurements.
The RLB0812-470KL is designed to meet the vibration requirements of IEC 60068-2-6, which specifies a vibration amplitude of 7.35 mm (0.29 in) at a frequency of 10-2000 Hz. However, it's essential to evaluate the specific vibration requirements of your application and consult with Bourns' technical support if you have any concerns.
To ensure the RLB0812-470KL meets your application's EMI requirements, follow proper PCB design and layout guidelines, such as keeping the inductor away from noise-sensitive components, using shielding, and implementing proper grounding techniques. Additionally, consider using EMI filters or common-mode chokes in conjunction with the RLB0812-470KL to further reduce EMI emissions.
