AFC5-F SERIES Dual output • 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.
