+5.1 Notes
Natural convection cooling, maximum. Forced air, atmosphere, maximum. Peak output current lasting less than seconds with duty cycle less than 10%. During peak loading, outputs outside total regulation limits. Peak total power must exceed bandwidth, peak-to-peak, measured differentially. Total regulation defined static output regulation including initial tolerance, load currents within stated limits, output voltages adjusted their factory settings. Also, 0.25 maintain stated regulation. minimum load required output obtain full current from negative output. Single output models have floating outputs which referenced either positive negative. Derating curve application specific ambient temperatures optimum reliability part heatsink should exceed semiconductor case temperature should exceed Caution: Allow minimum second after disconnecting power when making thermal measurements. Although minimum output current NFS40-79XXJ minimum load required achieve design MTBF. Three orthogonal axes, sweep octave/min, minute dwell four major resonances. This product only inclusion professional installers within other equipment must operated stand alone product. suffix indicates that these parts Pb-free (RoHS 6/6) compliant.

Mechanical Notes
order meet safety requirements, non-metallic stand-off mandatory hole specified mechanical drawing above. ground mounting hole near allows system grounding through metal stand-off. improve conducted noise, ground mounting hole near output connector should connected with ground mounting hole near metal stand-offs attached common metal chassis. This connection also significantly attenuates common mode noise. standard L-bracket enclosure available mounting which contains screws, connectors necessary mounting hardware. Order part number NFS40CJ.
