Thermistor 10K 3950 | Thin Film Temperature Sensor | MF55 Series

The MF55 is a thin film NTC thermistor. It senses temperature in very small spaces. Its thin, flexible body fits where stiff sensors cannot. This thermistor responds quickly. This makes it good for real-time temperature checks and safety circuits. Features and Benefits - Thin and flexible film - Its paper-thin shape lets it fit between battery cells. It can also bend to curved surfaces for direct contact. - Quick temperature response - Its low thermal mass helps it sense temperature changes almost at once. This is important for safety systems. - Wide temperature range - It works steadily from -40°C to 125°C. This covers most consumer and industrial electronics needs. - Standard resistance values - It comes in common values like 10K (3435 B-value) and 50K (3950 B-value). This makes it easy to add to existing designs. Applications - Putting it into a lithium battery pack. It checks individual cell temperatures and stops overheating. - Adding it to wearable tech or medical devices. It measures skin or room temperature accurately. - Attaching it to a CPU heat sink or 3D printer hotend. This gives exact temperature feedback and control. What It Is This product is an MF55 Series Thin Film Ultra-Thin NTC Thermistor, specifically a Thermistor 10K 3950. A thermistor is a type of resistor whose resistance is highly dependent on temperature. NTC stands for "Negative Temperature Coefficient," meaning its resistance decreases as its temperature increases. This particular thermistor has a B-Constant value of 3950K, indicating its thermal sensitivity. Its ultra-thin, thin film form factor makes it suitable for applications requiring minimal space. Key Uses & Applications Thermistors like the MF55 Thin Film Ultra-Thin NTC Thermistor are primarily used for temperature sensing and control. Because their electrical resistance changes predictably with temperature, they can be integrated into circuits to monitor thermal conditions. Common applications include temperature compensation, temperature measurement in tight spaces, and over-temperature protection in electronic devices. The 10KΩ resistance value and 3950K B-Constant make it suitable for a range of precise temperature detection tasks. How to Choose When selecting a thermistor, consider the required resistance value and B-Constant. This product offers resistance values of 5KΩ, 10KΩ, 50KΩ, and 100KΩ, with B-Constant options of 3435K and 3950K. The 10KΩ resistance and 3950K B-Constant are specified for this model. The "thin film, ultra-thin" form factor is crucial for applications where space is limited. Ensure the chosen specifications match the temperature range and accuracy demands of your project. Grit / Spec Guide This thermistor is part of the MF55 series. Key specifications include its NTC Sensor Type and its form factor as "Thin Film, Ultra-Thin". The B-Constant values available are 3435K and 3950K. Resistance values offered are 5KΩ, 10KΩ, 50KΩ, and 100KΩ. For this specific product, the resistance is 10KΩ and the B-Constant is 3950K. These values dictate the thermistor's response to temperature changes and its overall sensitivity. Care & Safety Thermistors are sensitive electronic components. Handle the Thin Film Temperature Sensor with care to avoid damage to the thin film element or leads. Avoid excessive mechanical stress or bending. When soldering, use appropriate techniques to prevent overheating, which can alter the thermistor's calibration or cause permanent damage. Ensure proper electrical insulation to prevent short circuits, especially given its ultra-thin profile. Store in a dry, room-temperature environment away from static electricity.
