March 9, 2017 - TT Electronics, a provider of engineered electronics for performance critical applications, has launched the QSOP-C and SOIC-C resistor networks.
With target markets in the aerospace, medical and industrial areas, the parts are aimed at designers of analogue circuits such as amplifiers and ADCs requiring accurate gain and threshold levels defined by resistance ratios, where the operating temperature range is wide, humidity levels may be high, reliability level is paramount and periodic recalibration is not possible.
TT Electronics’ QSOP-C and SOIC-C series resistor networks are designed for use in aerospace and high reliability signal processing applications, as the parts are optionally available with thermal shock screening. Specific applications include flight computers, medical monitors and critical process monitors.
Factors driving the demand for these types of components are the use of COTs passive devices in the aerospace sector, and rising operating frequencies making low crosstalk a more important feature.
The QSOP-C series feature a resistor density with .025” lead spacing, and are available in standard JEDEC 16, 20, and 24 pin packages. The 24-pin version measures 8.66 x 6.02 mm including leads. Resistor ranges of 100R to 150K are available. The SOIC series are available in narrow and wide body versions in standard JEDEC 8, 14, 16, and 20 pin packages. 100R to 200K resistance ranges are available.
Both series share an operating temperature range of -55 to +125 ÔÇ∞C and come with precision figures of +/- 15ppm per degree C TCR (temperature coefficient of resistance) tracking, and +/- 0.05 % ratio tolerance.
