FAQs
What is MF-RX185?
The MF-RX185 is a series of resettable surface mount radial leaded PTC (positive temperature coefficient) thermistors designed for overcurrent and overtemperature protection in electronic circuits. These devices are ideal for applications requiring automatic resettable protection, such as power supplies, battery packs, and automotive electronics.
How Does MF-RX185 Work?
The MF-RX185 operates by dynamically adjusting its resistance in response to changes in temperature and current. When an overcurrent or overtemperature condition occurs, the resistance of the PTC thermistor increases rapidly, limiting the current flow and protecting the circuit. Upon cooling, the thermistor automatically resets to its low resistance state, allowing normal operation to resume.
How Many Pins does MF-RX185 have and What are the Functions of the Pinout Configuration?
The MF-RX185 is a radial leaded PTC thermistor with two leads. The pinout configuration includes:
- Lead 1: Connection point for the first lead.
- Lead 2: Connection point for the second lead.
What are the Pros and Cons of MF-RX185?
Pros:
- Resettable Protection: Provides automatic resettable overcurrent and overtemperature protection, eliminating the need for replacement after a fault condition.
- Compact Size: The radial leaded package offers space-efficient mounting and integration into various electronic designs.
- Reliable Performance: Offers reliable overcurrent and overtemperature protection for enhanced system durability.
- Wide Application Range: Suitable for a wide range of electronic circuits and systems requiring automatic protection.
Cons:
- Limited Maximum Current: May have a limited maximum current handling capability compared to non-resettable fuses or other overcurrent protection devices.
- Temperature Sensitivity: The trip point of the PTC thermistor may vary with temperature, requiring careful consideration in high-temperature environments.
Are There Any Equivalents/Alternatives to MF-RX185 for Recommendation?
Equivalents to the MF-RX185 series include the PRG series from Littelfuse and the Bourns MF-RX series. Alternatives to consider are the SMDJ series from Bourns and the PPTC series from Bel Fuse.
