| 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(R) 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.
