November 16, 2015 – Built on Z1 Foil Technology, FRSG Series is designed for high-temperature applications to +225°C. Surface-mount devices offer low TCR of ±2.5 ppm/°C max from -55 to +200°C, +25°C ref; tight tolerances to ±0.01%; and load-life stability to ±0.1% after 2,000 hours of working power at 200°C. Available in 6 case sizes from 0603–2512, RoHS-compliant resistors feature resistance range from 10 Ω to 125 kΩ with working power to 750 mW at +70°C and 300 mW at +200°C.

MALVERN, Pa. – To meet the growing demand for precise, stable, and reliable resistors that can operate in harsh environments, VPG Foil Resistors announced today that its Vishay Foil Resistors (VFR) brand has introduced a new series of ultra-high-precision Z1 Foil Technology wraparound surface-mount chip resistors designed for high-temperature applications to +225 °C. Featuring gold-plated terminals for design flexibility, FRSG Series devices offer low TCR of ±2.5 ppm/°C maximum from -55 °C to +200 °C, +25 °C ref.; tight tolerances to ±0.01%; and load-life stability to ±0.1% after 2,000 hours of working power at 200 °C.

“Built on Z1 Foil Technology, FRSG Series devices are able to extend the advanced performance features of Bulk Metal® resistors — including tight tolerances and excellent load-life stability — to high-temperature environments, without sacrificing their low TCR,” said Jacky Acoca, VFR director of sales and marketing. “In addition, the devices’ gold-plated terminals support a wide range of mounting methods used throughout the industry, providing designers with the flexibility to meet the needs of their specific applications.”

Optimized for down-hole drilling, oil and gas exploration, and avionics, military, and space (AMS) applications, the resistors released today offer a resistance range from 10 Ω to 125 kΩ, with any conceivable ohmic value within this range — to six digits — available with no additional cost or lead time effect. Available in six case sizes from 0603 to 2512, the devices provide working power to 750 mW at +70 °C and 300 mW at +200 °C.

The resistors feature a rise time of 1 ns with effectively no ringing, a thermal stabilization time of <1 s (within 10 ppm of steady state value), current noise of ≤0.010 µVrms/V of applied voltage (<-40 dB), and a voltage coefficient of <0.1 ppm/V. Offering the utmost in ESD immunity, the RoHS-compliant devices withstand electrostatic discharges of at least 25 kV for increased reliability and offer a non-inductive (<0.08 µH), non-capacitive design.

Rapid prototype samples are available on request. Production quantities are available in as few as 10 weeks.
