Epoxy Resin Encapsulated NTC Thermistors vs Glass Encapsulated NTC Thermistors

NTC thermistors are widely used in temperature measurement and control. NTC thermistors with different packaging methods have different performance characteristics. Choosing the appropriate packaging type is crucial for specific applications. This article will compare epoxy resin packaged and glass packaged NTC thermistors to help you select the most suitable product based on your actual needs.

Epoxy Resin Packaged NTC Thermistors

Epoxy resin packaged NTC thermistors generally have a smaller volume and flexible installation methods. The MF5A model uses epoxy resin packaging and has the following features:

Compact size:

Suitable for installation in small holes and can be advantageous in space-limited situations.

Fast response:

Epoxy resin packaged NTC thermistors are more sensitive to temperature changes and are suitable for applications requiring rapid response.

Application scenarios:

Space-limited electronic devices, such as small household appliances and precision instruments.

Temperature monitoring applications with high response speed requirements.

Glass Packaged NTC Thermistors

Glass packaged NTC thermistors have higher high-temperature resistance. Models include MF57, MF58, and MF59, with MF58 being the most common. Their main advantages are:

Higher heat resistance:

Glass packaging can withstand higher temperatures, especially suitable for applications in high-temperature environments, particularly when the temperature exceeds 200°C, the performance of glass packaging is particularly outstanding.

Mechanical strength:

The glass shell is more robust than the epoxy resin coating, with stronger resistance to mechanical shock and vibration.

Application scenarios:

High-temperature applications, such as industrial equipment, automotive electronics, aerospace, hair curlers, ovens, etc.

Temperature measurement requirements above 200°C.

Conclusion: Choose Based on Needs

If you need to measure high temperatures (above 200°C), especially in situations with high requirements for high-temperature stability, glass packaged NTC thermistors (such as MF58) are a better choice.

If your equipment has limited space, or requires a more sensitive response, and the operating temperature does not exceed 150°C, epoxy resin packaged NTC thermistors (such as MF5A) are more suitable.

The choice of packaging method ultimately depends on your specific application needs. Weighing factors such as temperature range, volume, response speed, and durability will help you make the best decision.
