ELECTRONICS: Providing design engineers with isolated and bussed network circuit options, TT electronics BI Technologies has developed two SON (aka QFN or DFN) 8-pad packaged sample kits. Designated SFN08AKIT and SFN08BKIT, the sample kits include four or seven ultra-stable thin film resistors configured in isolated and bussed circuits, respectively. Each sample kit contains 10 resistor networks, and the highly reliable networks are specified for voltage divider and gain setting circuits in the military, aerospace, industrial and medical arenas.
The SFN08AKIT sample kit contains networks with four isolated resistors. The following networks and resistance values are included in the kit: SFN08A1001CBQLF with resistance value of 1000Ω; SFN08A1002CBQLF with resistance value of 10,000Ω; SFN08A1003CBQLF with resistance value of 100,000Ω; SFN08A4701CBQLF with resistance value of 4700Ω; and SFN08A4702CBQLF with resistance of 47,000Ω.
The SFN08BKIT sample kit contains networks with seven bussed resistors. The following networks and resistance values are included in the kit: SFN08B1001CBQLF with resistance value of 1000Ω; SFN08B1002CBQLF with resistance value of 10,000Ω; SFN08B1003CBQLF with resistance value of 100,000Ω; SFN08B4701CBQLF with resistance value of 4700Ω; and SFN08B4702CBQLF with resistance value of 47,000Ω.
All SFN Series resistor networks feature absolute tolerance to ±0.25 percent, ratio tolerance to ±0.1 percent, TCRs to ±25 ppm/C and TCR tracking to ±5 ppm/C. Custom circuits are also available upon request.
The sample kits are free and available immediately. Typical pricing for the SFN Series networks is $1 each, with lead times of 12 weeks.
