PTC Resettable Fuses

PTC (Positive Temperature Coefficient) resettable fuses are special type of over-current protection devices used to guard against unexpected and potentially damaging over-current conditions. Unlike traditional fuses, these are re-settable and can be used to protect both low and high current applications. YQD080N0025 is one of the PTC resettable fuses designed to safeguard electrical circuits from unfavorable conditions.

Application Field of YQD080N0025

YQD080N0025 PTC resettable fuses excel in DC applications. The device is particularly suited for use in critical automotive, off-highway, audio and industrial control applications. This resettable fuse offers protections from thermal and current overloads which are highly common in today’s electronic products with its overload trip current at 7.5 amperes.

Working Principle of YQD080N0025

The YQD080N0025 PTC resettable fuses are made up of two parts – a positively temperature coefficient (PTC) sensing element and an integrated single pole switch. The sensing element consists of a low-resistance ceramic element that can detect an increased current flow through the PTC element at the point of the circuit and switch off the integrated DC switch.The integrated DC switch is normally off at appropriate operating conditions, and when a current flow starts passing through the PTC element the resistivity of the ceramic element is increased. When the current exceeds the pre-determined current rating, the PTC element will become over-heated and the integrated DC switch will be turned off to halt the current flow. Once the PTC element cools down, the DC switch will turn back on and normal current flow is restored.This resetting feature makes the YQD080N0025 PTC resettable fuses a great choice for protecting your electronic circuits against thermal and current overloads. It provides superior protection compared to traditional fuses, and is more reliable and accurate than conventional thermal circuit breakers. This makes it ideal for use in industrial control and other applications where reliability is of utmost importance.

Advantages of YQD080N0025

The YQD080N0025 PTC resettable fuse has several advantages over traditional fuses, and other thermal circuit breakers. Firstly, this device is able to provide superior current protection, due to its PTC element. This assures that any sharp spikes or unexpected current changes does not go unnoticed. Secondly, its resetting mechanism makes sure that the fuse will always be in the reset state after a current overload has been detected. This eliminates the need to replace the fuse every time the current overload condition is detected, making it much more economical and efficient.Additionally, the YQD080N0025 PTC resettable fuse is also highly resilient against environmental stressors such as vibrations, shock and temperature. This makes it well suited for use in automotive, off highway, and industrial control applications.Lastly, the device is also highly suitable for use in low and high current application, and does not require any additional external components for operation. This makes it very easy to design and install, and allows for a much faster time to market.

Conclusion

The YQD080N0025 PTC resettable fuse offers superior current protection compared to traditional fuses and other thermal circuit breakers, and is highly suitable for use in automotive, off-highway, audio and industrial control applications. Additionally, the device can be easily installed and requires no extra components for operation. This makes it much more efficient and economic compared to other products, and it is one of the most commonly used PTC resettable fuses today.
