Triad Magnetics recommends a symmetrical PCB layout with the transformer centered on the board, and keeping the primary and secondary windings as close as possible to minimize leakage inductance and improve coupling.
Follow the recommended creepage distance of at least 3.2 mm between the primary and secondary windings, and ensure that the transformer is properly insulated with a suitable insulating material, such as a conformal coating or potting compound.
The FD4-20 has a maximum operating temperature range of -40°C to +125°C, with a derating of 1.5% per degree Celsius above 100°C.
Yes, the FD4-20 is designed to withstand high-vibration environments, but it's recommended to follow Triad Magnetics' guidelines for vibration testing and to ensure that the transformer is properly secured to the PCB or chassis.
The correct turns ratio depends on the specific application requirements, such as the input and output voltage, current, and power. Consult Triad Magnetics' application notes or contact their technical support for guidance on selecting the optimal turns ratio.
