The E2741's small size, encapsulated package makes it the ideal power source for applications where small size, high efficiency and reliability are critical. E200 Package Package Configuration .15[3,8] Min 1.26[32,0] Max .60[15,24] Max This inverter is designed to satisfy the most common cold-cathode lighting requirements for the Panasonic EDTCB03Q2F display. Custom units, providing different inputs, outputs or package refinements are available. .025[0,64] Square (5X) .700[17,78] .28[7,1] Connection Diagram .300[7,62] 2 1.100 [27,94] E2741 + 1 Vin - Endicott Research Group, Inc. * 4 5 2 page 4. 3 5 4 CCF Tubes 3 * Input bypass capacitor may be required (10uf - 100uf) 2601 Wayne St., Endicott NY 13760 607-754-9187 1 .400[10,16] .22[5,6] 1. 2. 3. 4. 5. .800[20,32] Vin(+) Vin(-) Common Vout(AC) Vout(AC) page 1.
