Notes:
1) P/N SMD604-05 provides two turns ratios.
For 1:1, use secondary pins 2-3.
For 1:1.26, use secondary pins 1-3.
2) P/N SMD625-05 has split secondary windings.
For 1:1, use secondary pins 1-2 and pins 5-6.
For 1:0.8, use secondary pins 3-4 and pins 7-8.
3) Part numbers may be modified as follows:
SMD6xxET-05 indicates -40C to +85C operation
