MLCCs combine 150°C operation with flexible terminations

Syfer X8R MLCC chips are available in case sizes from 0805 to 2225, voltages of 25V to 200V and capacitance values from 1nF to 1.8µF with FlexiCap™ polymer terminations as standard across the whole range. Syfer was the first manufacturer to introduce flexible polymer terminations to provide superior mechanical performance and minimise the chance of cracking the capacitor structure during assembly or in harsh operating environments.

Glueable hi-rel chip resistors rated up to 200°C

GCR  chip resistor

Compatible with most approved conductive adhesives, GCR series glueable chip resistors, from TT electronics Welwyn, are rated for operation from -55 to +200°C. They are available in resistance values from 1Ω to 10MΩ with power ratings from 0.125W in the 0805 size, up to 1W in the 2512 package. Planar and wraparound terminations are available in polymer-silver or gold with a nickel barrier. Their temperature coefficient of 100ppm/°C, or 200ppm/°C for values below 10Ω, ensures outstanding stability across the full rated temperature range. Evaluation samples, in selected resistance values, are available now, with other values available on request in 4-6 weeks.
