The LPTC-4050H and LPTC-4000H thermistors are high-precision PTC linear thermistors with a maximum temperature measurement of 125°C. Their resistance increases linearly with increasing temperature, demonstrating excellent linearity. Compared to PTC polymer ceramic thermistors, these thermistors offer superior linearity, eliminating the need for linear compensation measures and simplifying circuit design.

PTC thermistors are electronic components whose resistance increases significantly with increasing temperature. They exhibit self-healing properties, rapidly switching to a high-resistance state in the event of overcurrent or overheating, automatically disconnecting the circuit. They also automatically reset themselves after the fault is resolved. They are widely used in circuit protection, motor starting, and temperature sensing.

Composite thermistor is a combination of thermal coupling, The VDR varistor and PTC thermistor close to and packaged into one. Its main application in power meters and other power supply in the switching power supply and transformer primary At the same time to achieve the current, voltage integrated protection. Which solves the difficulty of using a single PTC thermistor in matching with the transformer. Over-voltage over-current state of the PTC thermistor protection instrument can not work properly, And cryogenic instrumentation exception PTC may not be protected And so on.

In inverter welding machines, the core function of a PTC thermistor is to act as an inrush current suppressor. Connected in series in the welding machine's power input circuit (before the rectifier bridge), it protects key components such as the rectifier bridge, filter electrolytic capacitors, and switching transistors (MOSFET/IGBT) from being damaged by the huge inrush current generated by capacitor charging during startup.

The KTY81, KTY82, KTY83, and KTY84 are a series of silicon-based positive temperature coefficient (PTC) temperature sensors. These are not traditional ceramic PTC thermistors, but rather semiconductor sensors that utilize the resistance-temperature characteristics of single-crystal silicon. Known for their exceptional accuracy, excellent linearity, high long-term stability, and reliability, these sensors are ideal for precise temperature measurement, compensation, and control over a wide temperature range of -55°C to +150°C (some models can reach +300°C).
