Description
MF Electronics thru-hole oscillators
embody 25 years of design and manu-
facturing know-how. They are available
in full-size and half size packages, all
hermetically sealed with welded stainless
steel cover. These 5V thru-hole oscilla-
tors are designed for everyday stresses
of 0°C to 70°C operation and extended
frequency selection of 1 KHz to 175
MHz. Higher (5V) operation ensures
superior output loading and faster
rise/fall times characteristics.
