describe

The SMD glass-sealed NTC thermistor is a surface-mount (SMT) temperature sensing component manufactured using an innovative process. It successfully combines the ultimate reliability of traditional glass sealing with the production efficiency of modern surface mount technology (SMT) . Its structural core is an NTC ceramic chip sealed in a miniature, rugged glass housing with metallized electrodes on the bottom, enabling it to be directly mounted on a PCB via reflow soldering.

Specification

MF58 Glass Encapsulated Ntc Thermistor
Model: MF58
B value: 3470 ~ 4400
Resistance: 2K-1000KΩ
Working temperature: -55 ~ + 250 ℃
Product features: small size and high precision

Highlight features

1. Extreme environmental tolerance and long-term stability:
Inheriting the DNA of glass sealing, it provides a completely airtight package that can effectively isolate it from water vapor, humidity, salt spray , and various corrosive gases . This ensures that its resistance value will not drift due to moisture penetration in extremely harsh environments, and has unparalleled long-term measurement stability and reliability.

2. Excellent high temperature working ability:
The glass material itself is heat-resistant, enabling it to withstand higher reflow temperatures and operate within a wide temperature range of -55°C to +250°C , far exceeding the performance of ordinary epoxy resin or plastic-encapsulated chip NTCs.

3. Compatible with automated surface mount (SMT):
It adopts standard SMD package (such as 0805, 0603, etc.), which is very suitable for high-speed SMD machines and reflow soldering processes, greatly improving the efficiency of large-scale production, with high consistency and yield rate, while saving PCB space, in line with the development trend of miniaturization of electronic equipment.

4. High mechanical strength and thermal shock resistance:
The micro glass body has a strong structure and can withstand the bending stress of the PCB board and severe temperature cycles (thermal shock). It has excellent anti-vibration, anti-impact and thermal shock resistance and a long service life.

Main Applications

• Automotive electronics : High-reliability temperature monitoring in high-temperature and high-vibration environments for under-the-hood components such as engine control units (ECUs), transmission controls, battery management systems (BMSs), and on-board chargers (OBCs).

• Industry and Communications : Precise temperature management and overheating protection for industrial inverters, servo drives, base station power amplifiers, and outdoor communication equipment to cope with harsh outdoor environments.

• High-end consumer electronics : Internal temperature monitoring with extremely high reliability requirements, such as data center servers and storage devices.

• Smart home appliances : temperature sensing in humid and high-temperature environments such as high-end dishwashers and dryers.

Summarize

The SMD glass-sealed NTC thermistor is a high-end temperature sensor designed to withstand harsh environments and be compatible with modern automated production. It perfectly balances high environmental reliability with automated production efficiency , making it the preferred component for automotive electronics, industrial control, and high-end communications equipment seeking ultimate performance and reliability.
