Description

The HW-68 PTC linear thermistor utilizes a positive temperature coefficient (PTC) material, where its electrical resistance increases linearly with rising temperature. This predictable 3000 PPM coefficient enables straightforward integration into temperature sensing circuits without complex linear compensation, providing a stable analog voltage signal proportional to temperature changes.

Constructed with a durable SMD package that meets standard resistor footprints, it is designed for reliable performance in harsh environments. Its operational range from -40°C to 180°C makes it suitable for applications requiring monitoring beyond typical electronic device limits, offering a high-value alternative to platinum RTDs like PT100/PT1000 in many scenarios below 180°C.

Frequently Asked Questions

What is the nominal resistance and temperature coefficient of the HW-68 thermistor?

The HaiWang HW-68 has a nominal resistance of 10 kΩ at 25°C and a positive temperature coefficient (PTC) of 3000 PPM/°C. This means its resistance increases linearly by approximately 30 Ω per degree Celsius rise in temperature, providing a predictable analog signal for temperature measurement.

What is the operating temperature range and power rating?

This thermistor is rated for continuous operation from -40°C to +180°C, making it suitable for harsh environments. Its power rating is 1/6 Watt (approx. 167 mW), which is standard for SMD thermistors and ensures stable performance without self-heating effects in typical sensing circuits.

How do I interface the HW-68 PTC thermistor with a microcontroller like Arduino?

Interface the HW-68 by connecting it as part of a voltage divider circuit. Connect one end to a reference voltage (e.g., 3.3V or 5V) and the other end to a pull-down resistor, with the junction fed into an analog input pin on your microcontroller. The ADC reading will correspond to the thermistor's resistance, which can be converted to temperature using its PTC coefficient or a lookup table.

Can this PTC thermistor replace a PT100 or PT1000 sensor?

Yes, the HW-68 can serve as a cost-effective alternative to platinum RTDs like PT100 or PT1000 in applications where the temperature does not exceed 180°C and extreme precision is not required. Its linear PTC characteristic simplifies circuit design compared to NTC thermistors, though calibration may be needed for specific accuracy requirements.
