Description

MF52 is a bead-type NTC (negative temperature coefficient) thermistor encapsulated with epoxy resin. It is one of the most widely used and cost-effective temperature sensing and compensation components in electronic circuits. Its core is a ceramic thermal chip sintered from metal oxides such as manganese, cobalt, nickel, etc. The outside is encapsulated from a solid epoxy resin material, providing good insulation and environmental protection.

In short, the MF52 epoxy resin NTC thermistor is a basic temperature sensing element characterized by high cost performance, high reliability and wide applicability. It is a classic and reliable choice for temperature management in various consumer electronics and industrial products.

Highlights

1. High sensitivity and high accuracy: As an NTC thermistor, it is highly sensitive to temperature changes, and the resistance value decreases significantly with the increase of temperature, and can detect slight temperature changes. Although the accuracy and consistency are usually slightly lower than that of the MF55 in the film process, it can still provide a variety of accuracy levels (such as ±1%, ±3%, ±5%) through sorting to meet the needs of most general-purpose scenarios.

2. Excellent cost-effectiveness: mature manufacturing process, large output, and extremely competitive price. It is the first choice for cost-effective temperature sensor solution.

3. Good stability and reliability: Epoxy resin packaging not only protects the internal brittle ceramic chip from damage from mechanical stress, vibration and impact, but also effectively resists moisture, dust and most chemical gases, ensuring long-term working stability in complex environments.

4. Fast thermal reaction speed: Due to the small package size and small thermal mass, it responds to changes in ambient temperature and has a small time constant.

5. Wide selection of resistance and B value: The MF52 series provides a variety of room temperature resistance values ​​(such as 10kΩ, 50kΩ, 100kΩ, etc. at 25℃) and B value (such as 3435K, 3950K, 4100K, etc.), which facilitates engineers to flexibly select according to different temperature measurement ranges and control requirements.

6. Easy to install and use: Its axial lead structure is very suitable for fixing on the circuit board through through-hole insertion (THT), which is easy to install and firmly soldered.

Main applications

• Temperature measurement and control: Household appliances (such as air conditioners, rice cookers, water heaters, refrigerators), battery pack temperature monitoring, automotive electronics, office equipment, etc.

• Temperature compensation: used to compensate other temperature-sensitive components in the circuit, such as crystal oscillators, amplifier circuits, etc., to ensure their working point is stable.

Surge suppression: In the power supply circuit, its cold state high resistance and hot state low resistance characteristics can effectively suppress the surge current when powered on.
