Introduction of highly durable and highly reliable thin film chip resistors (ERA*V/K/P series)

This video explains the features of the highly durable and highly reliable thin film chip resistors (ERA*V/K/P series) that Panasonic has recently added to its high precision series. In recent years, there has been a demand for higher precision and increased reliability of devices, particularly in the automotive and industrial sectors. In response to these demands, we have commercialized a highly durable and highly reliable thin film chip resistor with improved robustness compared to conventional products, featuring a resistance value tolerance of 0.05 to 0.1% and a temperature characteristic of 10 to 25ppm/℃.
