With the development of electronic technology, NTC chip It is increasingly being adopted in a wide range of applications that require temperature monitoring, control, and compensation.
Today, we’ll briefly introduce a method suitable for… High-precision NTC chip for medical temperature probes Modern technology centers on NTC chips, and NTC thermistors and temperature sensors—available in various package types—are widely used in a range of medical temperature probes. In circuits, they serve as the core component that converts temperature variations into the desired electrical signals.
Taking a 10 kΩ NTC thermistor as an example, its B‑value can be precisely controlled within B25/50 = 3935 ± 0.3% through a specific formulation, while its resistance at 25°C can be adjusted to achieve high accuracy of R25 = 10 kΩ ± 0.3%. During this adjustment process, the initial resistance of the NTC chip is slightly lower; as it undergoes fine grinding, its resistance gradually increases. With precise control of the grinding process, the resistance can be stabilized to within one part per thousand. In mass production, a resistance tolerance of ±3% yields a 90% yield rate, thereby effectively enabling precise resistance tuning of NTC thermistors.
