S30R / A30R, S30V / A30V Vishay Thin Film Center Tap Chip Resistor FEATURES 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. • 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 TYPICAL PERFORMANCE ABS TCR 50 TOL 1 CHIP DIAGRAM Equal Value (S30R, A30R series) Unequal value (S30V, A30V series) HYBRID STANDARD ELECTRICAL SPECIFICATIONS TEST SPECIFICATIONS MATERIAL Resistance Range TCR: CONDITIONS TAMELOX® TANTALUM NITRIDE 4.7 - 1M ohm Silicon 4.7 - 52K ohms alumina Tracking ± 2ppm/°C ±5ppm/°C - 55°C to +125°C Absolute ± 50ppm/°C ±100ppm/°C - 55°C to +125°C Absolute Tolerance: Resistance Ratio Accuracy Power Rating: Stability (∆R Ratio) Voltage Coefficient Working Voltage ± 20% to ± 0.1% ± 2% Standard 250mW Less than 0.1% Max. ∆R/R > 5ppm/Volt - 55°C to + 125°C Storage Temperature Range - 55°C to + 125°C Thermal EMF Shelf Life Stability 2,000 hrs. @ +70°C 100V Max. all styles Operating Temperature Range Noise @ + 70°C (0.05% typical) - 35dB 0.08µV/°C 100ppm 1 Year @ +25°C VISHAY THIN FILM • FRANCE +33.4.93.37.28.24 FAX: +33.4.93.37.27.31 • GERMANY +49.9287.710 FAX: +49 9287.70435 • ISRAEL +972.3.557.0945 FAX: +972.3.558.9121 • ITALY + 39.2.300.11919 FAX: +39.2.300.11999 • JAPAN +81.3.5464.6411 FAX: +81.3.5464.6433 • SINGAPORE +65.788.6668 FAX: +65.788.0988 • SWEDEN +46.8.594.70590 FAX: +46.8.594.70581 • UK +44 191 514 8237 FAX: +44 1953 457 722 • USA: (610) 407-4800 FAX: (610) 640-9081 Document Number: 60073 Revision 01-May-03 www.vishay.com 165 S30R / A30R, S30V / A30V Vishay Thin Film Center Tap Chip Resistor DIMENSIONS ALUMINA1 SILICON Thickness (Mils) 10 ± 2 14 ± 2 Isolation Layer None SiO2 (10,000 Å Min.)
