DC-DC Converter Transformers

SURFACE MOUNT
PICO surface mount units utilize materials and methods to withstand extreme temperatures of vapor phase, I.R., and other reflow procedures without degradation of electrical or mechanical characteristics.

These units can be used as self saturated or square wave driven
Input voltages of: 5V, 12V, 24V and 48V
Output voltages up tp 300 Volts
Power levels up to 40 Watts
Moisture Sensitivity Level: MSL3
Terminals: Meets solderability per MIL-STD-202, Method 208.

All units can be supplied with higher or lower output voltages.
Delivery-Sample orders typically ship within two weeks.
