Additional Details

The TFKS186P series features a robust epoxy package that provides protection against environmental factors. The internal IR filter effectively blocks visible light and other unwanted radiation, ensuring accurate signal detection. The devices operate with a supply voltage typically between 2.7V and 5.5V. The output signal is typically active low, providing a logic low signal when an IR signal is detected. Different carrier frequencies are available to suit different application requirements. The datasheet provides detailed specifications on sensitivity, noise immunity, and timing characteristics. The receivers are designed to operate in a wide temperature range. The pinout configuration depends on the specific package type within the TFKS186P series.
