The recommended land pattern for the 2773008112 inductor is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder-mask-defined (NSMD) pad shape to ensure proper soldering and thermal relief.
To handle thermal considerations, ensure a minimum of 10 mm clearance around the inductor to allow for airflow and heat dissipation. Also, consider using a thermal interface material (TIM) to improve heat transfer between the inductor and the PCB.
Although the datasheet doesn't specify a maximum voltage, as a general rule, it's recommended to derate the voltage by 20-30% to ensure reliable operation. For the 2773008112, a maximum voltage of 250-270 Vrms is a safe operating range.
To minimize EMI, use a shielded inductor or add a shield can around the inductor. Additionally, ensure the inductor is placed away from sensitive components and use a ground plane to reduce radiation. Proper PCB layout and routing can also help reduce EMI.
The SRF of the 2773008112 inductor is not explicitly stated in the datasheet. However, based on similar inductors, the SRF is likely to be in the range of 50-100 MHz. To determine the exact SRF, perform impedance vs. frequency measurements or consult with Fair-Rite Products Corp directly.
