TRIPLE OUTPUT EXTERNAL CAPACITOR

B4-53

HR40 SERIES

4 WATT

Notes

1. External capacitors required to prevent damage to internal circuitry

(see Table 2 for specifications).

2. Minimum load required on main output for full power auxiliary oper-

ation.

2. Capacitors should be high quality, low ESR components —

solid tantalum is recommended.
