The recommended PCB land pattern for the SDS680R-332M is a rectangular pad with a size of 3.8mm x 2.5mm, with a 1.3mm x 1.3mm thermal pad in the center. The pad should be solder-mask defined (SMD) with a non-solder-mask-defined (NSMD) thermal pad.
To ensure proper thermal management, it is recommended to provide a thermal path from the inductor to a heat sink or a large copper area on the PCB. A thermal interface material (TIM) can be used to improve heat transfer. The maximum operating temperature of the inductor is 125°C.
The self-resonant frequency (SRF) of the SDS680R-332M is not explicitly stated in the datasheet. However, based on the inductor's characteristics, the SRF is typically in the range of 100-200 MHz. It's recommended to consult with the manufacturer or perform simulations to determine the SRF for a specific application.
The SDS680R-332M is designed to meet the vibration requirements of IEC 60068-2-6, which specifies a vibration amplitude of 7.35 mm and a frequency range of 10-2000 Hz. However, it's recommended to consult with the manufacturer or perform additional testing to ensure the inductor's reliability in a specific high-vibration environment.
The equivalent series resistance (ESR) of the SDS680R-332M is not explicitly stated in the datasheet. However, it can be estimated using the inductor's DC resistance (Rdc) and the quality factor (Q) at a specific frequency. The ESR can be calculated using the formula: ESR = Rdc / Q.
