Introduction of PTC Resettable Fuses

PTC Resettable Fuses, also known as polyfuses, are a type of resettable protection devices used to protect electrical circuits from abnormal over-voltage, over-current or over-temperature conditions. Polyfuses are initially composed of two elements: an electrically conductive element, usually made of a polymer compound, and a positive temperature-coefficient (PTC) material that becomes resistive once it reaches a certain temperature. Once the current passing through the device exceeds its specified threshold, the PTC material heats up and causes a circuit interruption. This interruption can be transient or permanent depending on the device and application.Polyfuses are widely used to protect low-power electronic circuits and provide a reliable, low-cost, and easy-to-use replacement for traditional fuses, enabling many new designs, such as broader and more diverse circuit protection applications.

Specification of 0ZRB0185FF1E

The 0ZRB0185FF1E PTC Resettable Fuse is a rated current of 18A, rated voltage of 250VAC, and hold voltage of 135VAC. It has an operating temperature range of -40°C to 150°C and a thermal response time of 5 minutes. It has a total resistance of 0.4 ohms and has an interrupting capacity of 5000 amps. The device also comes with a UL Recognized and CSA Certified component rating.

Application Field of 0ZRB0185FF1E

The 0ZRB0185FF1E PTC Resettable Fuse is suitable for a wide range of applications such as power supplies, lighting, load starters, and other general purpose circuits. They can be used in AC and DC circuits with a range of operating voltage including 220/230VAC, 12/24V DC, and even higher voltages. Due to its fast response time and low total resistance, it is also suitable for use in applications with high current loads.

Working Principle of 0ZRB0185FF1E

The 0ZRB0185FF1E PTC Resettable Fuse is based on the principle of temperature-dependent resistivity, where a special PTC material starts to increase its resistance once its temperature exceeds the device’s threshold. When an abnormal over-current, over-voltage, or over-temperature condition occurs, the PTC material heats up and causes a circuit interruption. This interruption can be either transient or permanent, depending on the application.The resettable current begins flowing once the current, voltage, or temperature returns to a safe level. During this process, the PTC material cools and the current flows uninterrupted again. This type of circuit protection is much more reliable than a standard fuse, since it can be reset and used multiple times instead of needing to be replaced.

Advantages of 0ZRB0185FF1E

The 0ZRB0185FF1E PTC Resettable Fuse has many advantages over traditional fuses, such as:• It is a fast-acting device with a thermal response time of 5 minutes, reducing the risk of permanent damage to the circuit.• It is compact in size and does not require additional hardware for mounting.• It is easy to reset by simply removing the power from the device.• Its resistance remains low, reducing power loss in the circuit.• Its performance remains constant throughout its lifespan, providing higher quality and better protection.• It is easy to source from most electronics suppliers.• They are relatively inexpensive compared to traditional fuse devices.In summary, the 0ZRB0185FF1E PTC Resettable Fuse is a rugged, low-cost, and reliable solution for a wide range of circuit protection applications. Its ease of use and fast response time make it an excellent choice for any circuit protection solutions.
