Vishay Intertechnology announced a new AEC-Q200-qualified version of its PTS series of platinum SMD flat chip temperature sensors. Designed to provide accurate and stable temperature sensing for automotive, space, and industrial electronics, Vishay Beyschlag PTS AT series devices combine enhanced thermal cycling performance with higher operating temperatures to +175 °C.
Thanks to a highly controlled platinum thin film manufacturing process, the sensors released today offer an outstanding stability of temperature characteristic of ≤ 0.1 % after 1000 hours, ensuring precise and reliable operation even under harsh conditions. Typical applications for the devices include A/T controllers, oil quality / level sensor modules, and ARS controllers.
The PTS AT series sensors offer resistance values of 100 Ω, 500 Ω in the 0805 size and 100 Ω, 500 Ω, and 1 kΩ in the 1206 size; F0.03 and F0.6 tolerance classes; and a near linear temperature charateristic of +3850 ppm/K.The devices feature short reaction times down to ≤ 3 s (in air) and a wide operating temperature range from -55 °C to +175 °C.
The sensors support lead (Pb)-free soldering and are suitable for processing on automatic SMD assembly systems using wave, reflow, or vapor phase processes in accordance with IEC61760-1. A special coating provides electrical, mechanical, and climatic protection.
Terminations for the lead (Pb)-free devices are pure tin on nickel plating, and the immunity of the plating against tin whisker growth has been proven under extensive testing. The RoHS-compliant sensors comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances and are tested in accordance with IEC 60751, IEC 60068, and AEC-Q200 standards.
Samples and production quantities of the PTS AT series sensors are available now, with lead times of 10 weeks for larger orders.
