For dual inline package replace ‘S’ in model number with ‘D’.
For optional 3 kV isolation add suffix ‘-H’ to the model number.
For dual output delete suffix ‘A’ & split output current equally between rails.
For optional Remote On/Off on SIP models, add suffix ‘-R’ to model number.
Applying 5 V via 1 k current limiting resistor and diode turns output off.
Output capacitor of 100
μF
required to meet quoted ripple & noise.
Minimum load of 25% required to meet quoted specifications.
Operation at no load will not damage the converter but it may not meet all specifications.
Pin pitch tolerance: ±0.014 (±0.35), Case tolerance: ±0.02 (±0.5)
