AFC5-F SERIES

Dual output

[ 2 YEAR WARRANTY ]

• Linear regulated outputs

• Very low output noise

• 2 x 1 x 0.375 inch package

• Six sided shielding

• Short circuit protection

• UL94V-0 case

The AFC5-F Series of fixed frequency DC/DC converters provide 5 Watts of

power, low output noise and tight output regulation, all housed within a 2 x 1

inch case. Six sided shielding to negate radiated noise and a non conductive

base to prevent shorting to the PCB are standard features. Short circuit

protection, isolation voltage of 500VDC, and a voltage accuracy of ±1% are

included to offer the best possible solution to a system designer’s low power

needs. Ideal applications for the AFC5-F are data acquisition, digital to analog

and analog to digital conversion. AFC5-F Series DC/DC converters are suitable

for a wide range of general industrial applications, especially where low noise

levels are required.
