Baseplate Operating Temperature Range None Derating …………………………… -25°C to +85°C Cooling ………………………….….…… Free Air Convection Storage Temperature Range …..…………. -40°C to +105°C Dimensions ……………………………..… 2.4- 4.6- 0.5 inches (61.0- 116.84- 12.7 mm) NOTE 1. di/dt= 0.1A/1u S, Vin=48V,Tc=25°C; load change =0.5 Io max. to 0.75 Io max. and 0.75 Io max. to 0.5 Io max. 2. Measured with 10u F tantalum capacitor and 0.1u F & 1u F ceramic capacitor across output. 3. Measured from high line to low line. 4. Measured from full load to 1/4 load. 5. Maximum capacitive load across the output ports should not over following indicated values. 6. This converter required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, However they may not meet all listed specification. 7. Standard product is active low, active high remote on/off option is available, to order suffix a “H” to the model number e.g. UM3211H STANDAR...
