PRODUCT DESCRIPTION
0.1
The NTF 1W series of surface mount DC/DC
converters offer a tightly regulated output voltage
in a true surface mount device, available with
three 2:1 input voltage ranges of 4-6V, 9-15V
and 18-36V. The NTF series’ employs leadframe
technology and transfer moulding techniques to
bring all of the benefits of IC style packaging to
hybrid circuitry. Co-planarity of the lead positions
is based upon IEC 191-6:1990. The devices are
suitable for all applications where high volume
production is envisaged.
