Product Overview and Key Specifications of Linear Resistor PTC Thermistor
Linear Resistor increases resistance linearly with temperature, simplifying circuit design by eliminating the need for compensation. This makes the PTC Thermistor superior to traditional PTC polymer ceramic thermistors.

Simplified Circuit Design with KTY81/KTY82/KTY83/KTY84 -130
Unlike typical PTC Thermistor, which requires compensation due to non-linear resistance-temperature behavior, the KTY81/KTY82/KTY83/KTY84-130 maintains a linear relationship from -40°C to 300°C. This reduces complexity in temperature detection and compensation circuits, setting it apart from general PTC Thermistor, which are commonly used for overcurrent protection with narrow linear regions.

Flexible Integration and Circuit Design
Linear Thermistor with the same temperature coefficient, such as KTY84-130, can be connected in series or parallel without affecting its temperature-resistance characteristics. Esimerkiksi, a 1K 2000PPM Linear Resistor can be configured in series to form 2K 2000PPM or in parallel to create 500Ω 2000PPM. This flexibility supports optimized circuit experiments, data acquisition, and mass production.

Advantages of Linear Resistor KTY81/KTY82/KTY83/KTY84 Series
KTY series Linear Resistor offers several advantages that make it ideal for precise temperature sensing applications.

Precision and Accuracy
The Linear Resistor in the KTY series provides high-accuracy temperature measurement, with deviations typically within 1% kohtaan 5%. This level of precision is essential for applications requiring reliable temperature monitoring.

Excellent Stability
One of the main advantages of the KTY series PTC Thermistor is its long-term stability. It experiences minimal temperature drift over time, making it ideal for use in environments where consistent performance is critical.

Linear Resistance Response
Unlike standard thermistors, the KTY Linear Thermistor shows a linear increase in resistance as temperature rises. This characteristic simplifies the circuit design, ensuring a predictable response across various temperature ranges.

Durable and Robust Design
The KTY81/KTY82/KTY83/KTY84 and other KTY series KTY Linear Resistor are designed to withstand harsh environmental conditions. Their robust construction ensures they remain reliable even under stress, making them suitable for a wide range of applications.

Compact and Easy to Integrate
The KTY series comes in small, standardized packages. This compact design allows for easy integration into a variety of systems without sacrificing performance.
