1. KTY84 temperature sensor chip, the structure is based on the principle of diffusion resistance, with a true approximate linear temperature coefficient, ensuring high accuracy of temperature measurement. (The temperature changes from -40°C to +180°C, and the resistance value changes approximately linearly from about 300Ω to 1600Ω.)
2. KTY84 temperature sensor chip, based on "silicon batch processing technology", has good product consistency and strong interchangeability."
3. KTY84 temperature sensor chip, the main component is silicon, silicon is inherently stable, so it has extremely high reliability and extremely long service life (it has very little drift in up to 50 years, repeating its characteristics for millions of times The curve remains unchanged.)
4. KTY84 temperature sensor chip, the electrode is a Ni-Sn composite electrode, which has high reliability and good solderability.
5. KTY84 standard components are DO-35 glass packaging structure with axial leads. The structure is firm, the electrode contact is stable, and it can be used in harsh environments such as high temperature, high humidity and extreme cold. The appearance is standardized, and it has a small size and fast response. advantage.
6. The KTY84 temperature sensor is packaged and connected with PTFE leads and heat shrinkable tubes, and can withstand temperatures above 200°C. The resistance and leads are connected by copper tape riveting.
VII Silicon Sensors Application Precaution Of The Silicon PTC Thermistor Temperature Sensor
Minimum lead wire length tailored to shall be ≥8mm.
In lead wire bending, bending point shall be more than 2mm away from glass body part.
Mounting and Handling Recommendations
Excessive forces applied to a sensor may cause serious damage. To avoid this, the following recommendations should be adhered to:
No perpendicular forces must be applied to the body
During bending, the leads must be supported
Bending close to the body must be done very carefully
Axial forces to the body can influence the accuracy of the sensor and should be avoided
These sensors can be mounted on a minimum pitch of >5 mm
Soldering and Welding
Avoid any force on the body or leads during, or just after, soldering.
Do not correct the position of an already soldered sensor by pushing, pulling or twisting the body.
Prevent fast cooling after soldering.
For hand soldering, where mounting is not on a printed-circuit board, the soldering temperature should be <300C the soldering time <3 s and the distance between body and soldering point >1.5 mm.
For hand soldering, dip, wave or other bath soldering, mounted on a printed-circuit board, the
soldering temperature should be <300C, the soldering time <5 s and the distance between body and soldering point >1.5 mm.
The distance between the body and the welding point should be >0.5 mm. Care should be taken to ensure that welding current never passes through the sensor.
