FC Series
The FC Series are ultra-low noise, high performance DC/DC converters that are packaged in low profile (0.4 inch high) cases. Essential quality performance features are designed and built-in. A high performance Pi input filter minimizes input reflected ripple, while 5-sided electrostatic shielding and tape-wound toroids, rather than pot cores, minimizeradiated EMI. Advanced circuit design techniques reduce conducted output noise in the form of current spikes, to an extremely low level.
