AFC5 SERIES
Single and 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 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 are data acquisition, digital to analog and
analog to digital conversion. AFC5 Series DC/DC converters are suitable for a
wide range of general industrial applications, especially where low noise levels
are required.
SPECIFICATION
All specifications are typical at nominal input, full load at 25C unless otherwise stated
