Thick-film resistors meet AEC-Q200 standard

A series of high-reliability thick-film chip resistors from KOA that are designed for high-precision use cases such as automation in industrial application or battery designs in the automotive sector are in stock at RS Components. The RS73 series of ultra-high-precision metal-glaze thick-film resistors offer tolerances of ±0.1% and a TCR of 25 ppm/°C.

 

The series has also shown excellent long-term stability characteristics in reliability tests with resistance changing only by ±0.2%, typically, or up to ±0.4% with long-term exposure to higher temperatures in harsh environments.

A key feature of the range is that the devices are AEC-Q200 qualified for use in automotive. In addition, the series employs the manufacturer’s advanced technological know-how to protect against ‘sulfuration’.

In this process, inner electrodes of chip resistors can react with sulphur gas, leading to the creation of silver sulphide and possible circuit disconnection.

Offering a resistance range from 100- up to 1M-Ohm, other key characteristics include an operating voltage of up to 100V, and up to 150V overload voltage; and an operating temperature range of –55 up to +155°C.

Designed for surface mounting, the chip resistor series comes with lead-free terminations to meet EU RoHS requirements, and is suitable for both flow and reflow soldering processes.
