A PTC thermistor is a temperature sensing device that is made of a combination of polymers and ceramics. It works by changing its resistance in relation to the temperature around it. The B59346A1502P20 is a type of PTC thermistor that is specifically designed for industrial and consumer applications.

The B59346A1502P20 is suitable for temperature measurements over a wide range (−40 °C to 150 °C). It is typically used for temperature compensation or overheat protection in various electronic systems and devices including air conditioners, refrigerators, electric motor drives, solar power systems, consumer appliances, and many others. It is also used for providing feedback in temperature control circuits or operating as a switch in an over temperature protection circuit.

The working principle of the B59346A1502P20 is based on the temperature-dependent resistive characteristics of a semiconducting material, which contains polymers and ceramic. Its resistance-temperature characteristics can be categorized into two regions: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). At temperatures below 25 °C, the B59346A1502P20 has an NTC behavior, meaning its resistance decreases as the temperature increases. However, when temperatures rise above 25 °C, the device has a PTC behavior, meaning its resistance increases as the temperature increases.

The device is composed of a ceramic pellet surrounded by polymer containment materials that retain its shape and protect it from mechanical stress. It is encapsulated in an epoxy body and a wire lead frame which allows connection to an electronic circuit. The device is easily connected to the circuit due to its compact size, measuring only 6 mm in height and 2.2 mm in diameter.

The B59346A1502P20 is a highly accurate device that offers good thermal stability and long-term performance due to its robust construction. It also features high thermal insulation, low current consumption, a low operation voltage of 5 V, a wide operating temperature range from -40°C to 150°C, and an operating resistance range from 5-100Ω. The device is extremely reliable, with an excellent life expectancy of over 270 million cycles.

The B59346A1502P20 is an ideal solution for thermal sensing applications where accurate temperature measurement is required. It is suitable for a wide range of both industrial and consumer applications, such as air conditioners, refrigerators, electric motor drives, and solar power systems. It is an excellent choice for applications that require an accurate, reliable, and durable temperature sensing device.
