Sample kits from TT Electronics BI Technologies provide design engineers with isolated and bused network circuit options. The two eight-pad packaged sample kits, the SFN08AKIT and SFN08BKIT, include four or seven ultra-stable thin film resistors configured in isolated and bused circuits, respectively. Each sample kit contains 10 resistor networks, specified for voltage divider and gain setting circuits in military, aerospace, industrial and medical applications. The networks measure just 4mm2, which is 40% smaller than a standard eight-lead SOIC narrow package, says the company. Specific applications for the networks in isolated and bused schematics include electronic measurement equipment, semiconductor processing equipment, ultrasound equipment, and flight control systems. The SFN08AKIT sample kit contains networks with four isolated resistors. The kit includes SFN08A1001CBQLF with resistance value of 1000Ω; SFN08A1002CBQLF, 10,000Ω; SFN08A1003CBQLF, 100,000Ω; SFN08A4701CBQLF, 4700Ω; and SFN08A4702CBQLF, 47,000Ω. The SFN08BKIT sample kit contains networks with seven bused resistors. Included are SFN08B1001CBQLF with resistance value of 1000Ω; SFN08B1002CBQLF, 10,000Ω; SFN08B1003CBQLF, 100,000Ω; SFN08B4701CBQLF, 4700Ω; and SFN08B4702CBQLF, 47,000Ω. All resistor networks have absolute tolerance to ±0.25%, ratio tolerance to ±0.1%, TCRs to ±25ppm/°C and TCR tracking to ±5ppm/°C. Custom circuits are available on request.
