During peak loading, outputs may go outside of total regulation limits. Peak total power must not exceed 60 W. 4 50 MHz bandwidth, peak-to-peak, measured differentially. 5 Total regulation is defined as the static output regulation at 25 °C, including initial tolerance, load currents within stated limits, and output voltages adjusted to their factory settings. Also, IA / IB to maintain stated regulation. 6 A minimum load of A is required on the +5 V output to obtain full current from the negative output. 7 Single output models have floating outputs which may be referenced as either positive or negative. 8 Derating curve is application specific for ambient temperatures > 50 °C, for optimum reliability no part of the heatsink should exceed 120 °C and no semiconductor case temperature should exceed 130 °C. 9 Caution Allow a minimum of 1 second after disconnecting the power when making thermal measurements. 10 Although the minimum output current of the NFS40-79XXJ is 0 A, a 4 W minimum load is required to achieve design MTBF. 11 Three orthogonal axes, sweep at 1 octave/min, 5 minute dwell at four major resonances. 12 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 13 The ‘J’ suffix indicates that these parts are Pb-free RoHS 6/6 compliant. 14 NOTICE Some models do not support all options.
