Product Overview
Thinking Industrial Corporation TTF-103 -- a Kapton polyimide-encapsulated thin film NTC thermistor with a base resistance of 10k Ohm at 25C. Approximately 0.02 inches thick with approximately 6-inch lead wires. The flat, flexible construction makes it suited for surface contact temperature sensing in tight or confined spaces where standard bead or resin-coated thermistors are too bulky.
Key Features
- Resistance: 10k Ohm at 25C (EIA code 103)
- Type: NTC (Negative Temperature Coefficient) thin film thermistor
- Encapsulation: Kapton polyimide insulation film -- flexible and low-profile
- Sensor thickness: approximately 0.02 inches
- Lead wire length: approximately 6 inches
- Operating temperature range: -40C to +100C
- Beta value: Not confirmed — verify against datasheet before use in calibrated circuits.
- Tolerance: Not confirmed -- verify with manufacturer datasheet
Applications
- Battery pack thermal monitoring -- flat form factor fits between Li-ion cells
- 3D printer heated bed temperature sensing
- Laptop and notebook internal thermal management
- Home appliance control boards -- refrigerators, air conditioners
- Arduino and Raspberry Pi temperature sensing projects
Frequently Asked Questions
What resistance does this thermistor read at room temperature?
10k Ohm at 25C. This is the standard R25 base resistance confirmed by the part number designation -- 103 is the EIA code for 10 x 10^3 Ohm.
What is the Beta value, and does it matter for my project?
Beta value is not confirmed for this unit. If your firmware or temperature control circuit requires a specific Beta constant -- such as 3435K or 3975K -- verify against the Thinking Industrial TTF-103 datasheet before use. A Beta mismatch will produce inaccurate temperature readings.
Does this require any supporting circuitry to function?
Yes. This thermistor must be used in a voltage divider circuit with a pull-up or pull-down resistor to produce a readable signal for a microcontroller ADC or dedicated temperature controller. It is a passive resistive element -- not a self-contained temperature transmitter.
Is this a surface-mount or through-hole component?
Neither in the traditional PCB sense. The TTF-103 is a flat film sensor with lead wires intended for surface contact mounting -- pressed against or bonded to a flat surface. It is not designed for insertion into cylindrical thermistor wells.
Lead length is approximately 6 inches based on sourcing documentation. Confirm mechanical fit before installation if lead length is critical to your application.
