PTC resettable fuses, often known as polymeric positive temperature coefficient (PPTC) devices, are electronic devices used in a wide variety of applications. They are also sometimes referred to as "self-resetting fuses" or "polyfuse". The MICROSMD035F-2 is a PPTC resettable fuse designed to protect a wide range of electronic circuits. By detecting and limiting excessive current conditions, the device prevents damage to the system in the event of an overload or short-circuit. This article will discuss the application field and working principle of the MICROSMD035F-2.
Applications of the MICROSMD035F-2
PTC resettable fuses are widely used in electronic products, including power supplies, consumer products, and industrial control systems. The MICROSMD035F-2 is used in many different types of applications, due in large part to its low cost, small size, and excellent current limiting performance. It is used in industrial, medical, mobile, and communications products, as well as in lighting, power tools, and other portable and stationary equipment. It is also used in automotive and marine applications, as it can protect vital electronic components from overload currents.
Working Principle of the MICROSMD035F-2
The MICROSMD035F-2 is a resettable thermal fuse that works on the principle of changing thermal resistance. At normal temperature, the fuse is enabled and the electrical current will pass through. When the temperature of the device increases due to excessive current, the resistance of the device will increase. This will cause the circuit to be broken, preventing further current from passing through and protecting the system from damage. The thermal resistance will reset after the temperature of the device has dropped back to normal.
The PTC resettable fuses are designed with trip point and current limit settings. The trip point determines the temperature at which the fuse will activate and disconnect, while the current limit setting defines the amount of current that the fuse will allow to pass before it breaks the circuit. The MICROSMD035F-2 has a trip point of approximately 97°C (207°F) and a current limit of 3.5A.
Conclusion
The MICROSMD035F-2 is a PTC resettable fuse designed to protect a wide range of electronics from excessive current conditions. It is small and inexpensive, making it popular in a variety of applications. In addition, it is rated with a trip point of approximately 97°C (207°F) and a current limit of 3.5A, making it an effective and reliable overload and short circuit protection device.
