Introduction to PTC Resettable Fuses

PTC Resettable Fuses are a type of over-current protection which rely on the phenomena known as “positive temperature coefficient” or “PTC”. The PTC resettable fuse has a built-in reset feature that allows it to automatically reset itself after a current over-load or a short-circuit has been removed or detected. This makes them particularly attractive for protecting sensitive applications and in automotive systems where hard-reset fuses may not be feasible.

0ZCH0110FF2E PTC Resettable Fuse

The 0ZCH0110FF2E is a polymeric Positive Temperature Coefficient Resettable Fuse (PTC) from TE Connectivity. This PTC has a trip current of 11 Amps (10A) and a maximum voltage rating of 48 volts DC. This fuse has a low operating temperature (down to -40°C) and high current capability. This PTC is RoHS compliant and provides superior protection for automotive and industrial applications.

0ZCH0110FF2E Application Fields

The 0ZCH0110FF2E is a versatile device which can be used in numerous applications. The most common applications for this type of fuse include automotive, industrial, and consumer electronics.In automotive applications, this device can be used to protect sensitive electronic components from current overloads or short-circuits. It can also be used to protect audio systems from overloaded speakers or amplifiers. In industrial applications, the 0ZCH0110FF2E can be used to protect equipment from high-amperage loading or short-circuits which could cause damage. In consumer electronics, this device can be used to protect sensitive components from overloaded batteries or power surges. It can also be used to protect computer components from current overloads.

0ZCH0110FF2E Working Principle

The 0ZCH0110FF2E PTC resettable fuse uses the Positive Temperature Coefficient (PTC) effect to protect circuits from current overloads and short-circuits. The 0ZCH0110FF2E contains a ceramic element which expands when the temperature rises due to an over-current flow in the circuit. This expansion causes a “domino effect”, effectively disrupting the current flow and disconnecting the circuit from the power supply. When the over-current or short-circuit has been removed, the ceramic element in the fuse will gradually cool down, causing it to shrink back to its original size. This restores the current flow and reconnects the circuit to the power supply. This resetting feature of the 0ZCH0110FF2E makes it an attractive over-current protection device for automotive and other sensitive applications.

Conclusion

The 0ZCH0110FF2E PTC Resettable Fuse is a versatile over-current protection device designed for automotive, industrial, and consumer electronic applications. This device takes advantage of the Positive Temperature Coefficient (PTC) effect to protect circuits from current overloads or short-circuits. When the temperature rises due to current flow, the element in the fuse expands and causes a “domino effect”, effectively disconnecting the circuit from the power supply. When the over-current or short-circuit has been removed, the element cools down and returns to its original size, restoring current flow and reconnecting the circuit to the power supply. This resetting feature of the 0ZCH0110FF2E makes it an attractive choice for protecting sensitive circuits.
