THIN FILM CHIP RESISTORS
68 Series 0.020”x0.020”
Satcon Electronics 68 series .020” x .020” Thin-film Chip Resistors are available in both top-contact
and back-contact versions in a wide range of resistances and tolerances. Values are available from
1 ohm to 500 Kohms. Both passivated nichrome and tantalum-nitride resistor versions are available.
Nichrome provides excellent stability and temperature coefficient in hermetic applications while
tantalum-nitride provides superior moisture-resistance for non-hermetic applications.
