Film-Packaged NTC

X-Meritan develops compact temperature sensing components for electronics requiring fast response, stable thermal detection, and environmental resistance. The multilayer structure uses transition metal oxides such as manganese and nickel, with the sensitive layer manufactured by magnetron sputtering.

The Film-Packaged NTC provides a typical thermal response within 3 seconds, operates from -40°C to +125°C, and features a B value of 3950 K. Its chemically inert outer film provides resistance to acids, alkalis, and organic solvents, making it suitable for industrial, medical, consumer electronics, and automotive applications.

Key Specifications

Performance

Fast Thermal Response

The low heat capacity of approximately 1 J/K reduces thermal lag and enables typical temperature stabilization within 3 seconds. This is useful for battery monitoring, medical instruments, and power electronics where rapid temperature changes need to be detected.

Wide Temperature Range

The operating range of -40°C to +125°C supports applications exposed to cold-start conditions, elevated ambient temperatures, and repeated thermal changes.

Chemical Resistance

The inert outer film protects the sensing structure against acids, alkalis, and organic solvents. For continuous exposure to highly concentrated corrosive vapors, application-specific validation is recommended.

Accuracy and Resistance

Temperature Accuracy

The available product information does not define a universal accuracy specification such as ±1°C or ±0.5°C. Actual system accuracy depends on resistance tolerance, B-value tolerance, circuit design, ADC resolution, installation, and calibration.

For projects requiring ±1°C or ±0.5°C, the target accuracy should be specified during RFQ so X-Meritan can evaluate the appropriate configuration.

Resistance Options

Resistance value should be selected according to the measurement circuit and target temperature range. Common NTC configurations include 10kΩ, 47kΩ, and 100kΩ, while the exact available values and tolerances should be confirmed for the selected X-Meritan model.

The values above are selection examples rather than universal specifications. Final parameters should be confirmed with the applicable datasheet.

Sensor Comparison

Technology Comparison

For compact electronic systems within the specified temperature range, the thin-film structure offers a practical combination of fast response, small size, and easy circuit integration.

Application Areas

Industrial Equipment

Film-Packaged NTC can monitor temperature in motors, transformers, and power supply equipment. Its wide operating range and rapid response support real-time thermal monitoring.

Medical Devices

Digital thermometers and diagnostic equipment can benefit from the low heat capacity and fast thermal response. For medical applications with strict accuracy requirements, the complete measurement system should be validated.

Consumer Electronics

The slim structure is suitable for smartphones, wearable devices, battery management systems, and other high-density assemblies where installation space is limited.

Automotive Electronics

The sensor can be used for engine compartment and battery pack monitoring. The Mn/Ni/Co oxide structure is designed for applications involving temperature variation and thermal stress.

Integration Notes

Self-Heating

Operating current should remain within the specified limits. Excessive current can cause self-heating and introduce temperature measurement errors.

Mechanical Handling

Avoid sharp bending, excessive pressure, or tensile stress on the film body during installation. The thin functional layer requires controlled handling.

Soldering

Use an appropriate industry-standard soldering profile to reduce thermal shock to the multilayer structure. Production soldering conditions should be validated before mass manufacturing.

RFQ Requirements

For OEM and bulk procurement, buyers should provide the required resistance value, resistance tolerance, B value, operating temperature, target accuracy, response time, dimensions, connection method, application environment, and estimated quantity.

For example, an RFQ can specify: 10kΩ or 100kΩ nominal resistance, ±1% tolerance, -40°C to +125°C operation, and ±0.5°C system accuracy. X-Meritan can then evaluate the appropriate configuration according to the actual application.

X-Meritan supports temperature sensing requirements for electronic manufacturers and OEM projects, including application-specific resistance, tolerance, dimensions, and performance requirements.
