Temperature Sensors - NTC ThermistorsNTC thermistors, also known as negative temperature coefficient thermistors, are temperature sensors that switch the electrical resistance in a specific manner depending on temperature. The resistance decreases with increasing temperature, making them often used as inrush current limiters, current-sensitive devices, temperature sensing or switching type components.One of the products in this category is the B57867S0302H140 NTC thermistor. This device is a chip component measuring 2.7mm x 2.2mm in size. It fits easily into tight spaces, making it ideal for a range of applications. It operates from a temperature range of -55°C to +150°C, with a linear negative temperature coefficient. This makes it an effective temperature sensor, with an accuracy of +/-3°C at 25°C.The B57867S0302H140 is built with a solid construction and a high resistance value of 26.2kΩ to 30kΩ at 25°C. It also has a low thermal time constant, helping to maintain a low temperature-sensing error. The high resistance and low thermal time constant reduce the need for external components when operating at low temperatures, making it an efficient and cost-effective sensor choice.In terms of applications, the B57867S0302H140 NTC thermistor is particularly suitable for use in dryer sensors, temperature switches, air conditioning systems, space temperature control devices, and mobile phone and computer components. Due to its small size, this device is ideal for tight spaces and systems with a short reaction time requirement.Working principle wise, the B57867S0302H140 works by changing its electrical resistance depending on the temperature. This is done via a special material, called a semiconductor, that changes its resistance depending on the temperature. This material is surrounded by a protective glass cover and is responsible for detecting changes in temperature with accuracy. Depending on the application, the resistance is either used as a temperature sensor or as a current-limiter, by providing higher resistance at lower temperatures. Additionally, the B57867S0302H140 also has an ESD protection feature, with a maximum voltage of 4V, giving it extra protection against Electrostatic Discharge. In addition, it also has a low contact resistance of 0.1mΩ, is resistant to vibration and has a large rated current of up to 5A.All in all, the B57867S0302H140 NTC thermistor is a versatile, easy to install and cost-effective temperature sensor solution. It is ideal for manufacturing in high volumes, as it has a small size and high resistance. In combination with its low thermal time constant and ESD protection, this thermistor makes it perfect for a range of applications.
