“Typically, the manufacturing process for thick-film chip resistors allows for variations in calibration adjustments that result in variations in pulse-handling performance,” according to the company, whose “RPCA series addresses these needs by providing reliable and repetitive impulse processing behavior.”
The key is that they are uncalibrated – available in 'standard power' versions with tolerances of 5%, 10% and 20% (graph on the left).
Sizes range from 0603 to 2512, and there are also 0402 types without a heart rate rating.< /p>
