S30R / A30R, S30V / A30V
Vishay Thin Film
Center Tap Chip Resistor
FEATURES
• 30 Mil Square Size.
• Resistance Range:
(Silicon Substrate)
Equal value - 4.7 ohms to 1M total
Unequal value - 4.7 ohms to 500K per resistor
(Alumina Substrate)
Equal value - 4.7 ohms to 52K total
Unequal value - 4.7 ohms to 26K per resistor
• Gold terminations with Tamelox
®
or Tantalum nitride resistor film.
• 4 digit custom marking available
• Low value indicator for unequal values
Actual Size
Center tap chip resistors allow for greater flexibility of hybrid
layout design by utilizing the smallest area for two resistors.
Since both resistors are from the same film system, excellent
tracking is inherent in the chip. Connecting to the center tap
yields half the value: connecting the two resistors in parallel
results in one quarter value on equal value resistor styles.

Alumina has the benefit of the higher thermal conductivity
and superior high frequency characteristics, however the
resistance range is limited by the poorer line resolution
versus silicon, because of the surface finish.
