Accurate temperature sensing is critical in applications such as:
Battery Management Systems
Power Supplies & UPS Systems
Industrial Control Equipment
Automotive Electronics
Medical Devices
NTC thermistors are widely used because of their high sensitivity, fast response, and cost-effectiveness. However, in harsh environments, some systems experience unexpected temperature measurement errors after months or years of operation.
What causes NTC drift? The most common failure mechanisms include:
1. Moisture Ingress & Ion Migration
In high-temperature, high-humidity environments, moisture can penetrate the sensor package and cause insulation degradation, leading to resistance drift and inaccurate temperature readings.
2. Mechanical Stress & Microcracks
PCB assembly, thermal cycling, vibration, or mechanical bending can create microscopic cracks inside the thermistor, affecting long-term stability and reliability.
3. Material Aging at High Temperature
Continuous exposure to elevated temperatures can gradually alter the ceramic structure of the NTC element, causing irreversible changes in resistance and B-value characteristics.
How JEC Improves Long-Term Reliability
At JYH HSU (Dongguan Zhixu Electronics), our NTC thermistors are designed for demanding applications through:
High-density ceramic materials for excellent stability
±1% resistance value and ±1% B value accuracy
Hermetic glass-sealed construction (MF51 Series) for superior moisture resistance
Enhanced vibration and thermal-shock resistance
For critical applications such as battery management systems, UPS systems, industrial controls, and automotive electronics, long-term stability is just as important as initial accuracy.
