RL4504-3.28-59-D1 is an NTC thermistor designed for precise temperature measurement and control applications. It features a nominal resistance of 5 O at 25°C with a ±20% tolerance and a temperature coefficient of resistance of -3.42%/°C at 25°C. The device operates over a wide temperature range of -50°C to +150°C with a dissipation constant of 10.0 mW/°C and a thermal time constant of 60 seconds. The thermistor has physical dimensions of 0.480 in (12.19 mm) maximum length, 0.040 in (1.02 mm) diameter, and 0.140 in (3.56 mm) maximum width, with 22 AWG leads extending 0.328 in (8.33 mm). This component is ideal for temperature sensing, compensation, and control circuits in industrial and commercial applications.
