High-Density Resistor Networks from TT Electronics are Ultra-Reliable for Critical Applications

Press release date: Mar 08, 2017

TT Electronics has launched the QSOP-C and SOIC-C high-density resistor networks that combine high precision with stability and reliability. By using a ceramic substrate and a relatively large feature size, they offer better cross-talk performance than types based on silicon substrates.

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 particularly beneficial 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 use of Tantalum Nitride film technology makes the QSOP-C and SOIC-C series resistor networks ultra-reliable as an inherently moisture-proof film system, and their ceramic based element offers lower crosstalk than silicon based alternatives. Reducing the PCB area required, up to 23 resistors are available in a single component.

The QSOP-C series feature a high 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°C and with precision figures of +/- 15ppm per degree C TCR (temperature coefficient of resistance) tracking, and +/- 0.05 % ratio tolerance, the resistors consume a smaller amount of the designer's error budget.

"We pioneered the use of Tantalum Nitride film technology to solve the moisture related reliability issues of industry standard Nichrome film technology. TT Electronics offers a class-leading, growing portfolio of ultra-high reliability discrete resistors and resistor networks," commented Stephen Oxley, Senior Engineer, Applications & Marketing, Resistors Business Unit, TT Electronics.

The QSOP-C and SOIC-C high-density resistor networks enable lifelong precision and ultimate reliability level in a compact, standard package. For circuit designers who need highly reliable, stable resistor networks, they provide higher stability and lower cross-talk performance than competing technologies.
