(ex: cmj r5s5-2000-r). 3. bellcore tr-nwt-000332. case 1: 50% stress, temper ature at 40oc. (gr ound fixed and controlled environment). 4. ?i? version is more efficient; therefore, it can be oper ated over a more extensive temp erature range than the standard ve rsion. please add the suffix ?-i? for industrial grade temperature range models. 5. heat sink is optional, plea se consult factory for ordering details. 6. maximum value at nominal input voltage and full load of standard type. 7. typical value at nominal input voltage and no load. 8. tested at minimum vin and constant resistive load. 9. chassis mount options: no suffix for open frame, ?u? suffix for u channel, and ?e? suffix for enclosed type. derating curves
