Product Advantages
The TCTR series utilizes a third-generation NTC thick-film chip technology with a special electrode structure. This results in temperature detection accuracy up to 1.2 across the full temperature range. The mature thick-film manufacturing process allows for a thermal response time as low as 2 seconds, twice as fast as comparable products. The thick-film structure minimizes thermal shock during soldering, making it suitable for applications requiring high stability and reliability. The special end electrode structure effectively releases mechanical stress from thermal shock and PCB bending.
