The TFPTL Series from Vishay/Dale features radial-leaded, positive temperature coefficient (PTC) thermistors with nickel thin film elements and two tinned copper clad steel wire leads. The TFPTL Series offers positive temperature coefficients of + 4110 ppm/K, fast response time of less than 2 s, and high stability over a wide temperature range from -55ºC to + 150ºC.

TAOS TSL2581 Light-to-Digital Converter is a very high sensitivity light-to-digital converter that transforms light intensity to a digital signal output capable of direct I2C interface. TAOS TSL2581 Light-to-Digital Converter combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit capable of providing a near-photopic response over an effective 16-bit dynamic range (16-bit resolution). Two integrating ADCs convert the photodiode currents to a digital output that represents the irradiance measured on each channel.
