PTCCL21H801HBE

PTC thermistors are temperature sensors which can measure the ambient temperature and provide an electrical signal as an output. The most common type of PTC thermistor is PTCCL21H801HBE, which is widely used in a variety of applications. This article will explain the application field and working principle of PTCCL21H801HBE.

PTCCL21H801HBE is mainly used in automotive, medical, consumer applications and industrial production lines, such as hot water supplies, vehicle cabin environments, refrigerator and freezers, cookers and ovens, air conditioning and HVAC systems, medical diagnostic equipment, and so on. It has a wide range of temperature measurement capability and can measure temperatures from -40°C to 125°C (-40°F to 257°F).

PTCCL21H801HBE works on the principle of Positive Temperature Coefficient of Resistance (PTC). It is made up of a ceramic disc which contains metallic particles. As the temperature rises, the particles inside the ceramic disc expand and the resistance of the PTCCL21H801HBE increases. This increase in resistance causes an increase in the electrical current passing through it, therefore the increase in temperature can be measured.

PTCCL21H801HBE also has an internal self-heating feature, which allows it to maintain an accurate and stable temperature sensing performance. The internal self-heating technology adjusts the electrical power applied to the sensor automatically and continually, so the measured temperature will be more precise and consistent than traditional thermistors. In addition, it also has a fast response time and does not require long warm-up periods.

PTCCL21H801HBE is an excellent temperature sensor for a variety of applications. Its wide temperature range, fast response time, and internal self-heating technology make it a good choice for many applications. It is reliable, accurate, and easy to use, making it a popular choice for automotive, medical, consumer, and industrial applications.
