Commercial Thin Film Chip Resistors
SURFACE MOUNT
CHIPS
These chip resistors are available in both “top side” and
“wraparound” termination styles in a variety of sizes. They
incorporate self passivated, enhanced Tantalum Nitride
films, to give superior performance on moisture resistance,
voltage coefficient, power handling and resistance stability.
The terminations consist of an adhesion layer, a leach
resistant nickel barrier, and solder coating. This product will
out-perform all requirements of characteristic E of
MIL-PRF-55342.
