This Vishay Dale PTCCL21H172DBE is a PTC (Positive Temperature Coefficient) thermistor designed for overload protection applications. It operates within a temperature range of -20°C to 85°C and can handle a maximum rated voltage of 1000V RMS.
The thermistor has a nominal resistance of 172Ω at 25°C with a tolerance of ±30%. Its nominal holding current is 10mA, and it has a maximum overload current of 0.5A. The switching temperature is 170°C.
Designed for through-hole mounting, this component comes in a radial lead disc package with dimensions of 20.5mm diameter and 4.0mm width. Its automatic resetting capability makes it suitable for applications requiring rapid protection against over-voltage or over-temperature conditions.
This PTC thermistor is suitable for protecting sensitive electronic instruments from excessive voltages. Under normal conditions, its resistance is low, allowing normal operation. During an overload, it switches to a high-resistance state, absorbing excess current and protecting the connected device. Once the overload is removed, it returns to its low-resistance state.
