0ZCK0035FF2G Circuit Protection

PTC Resettable Fuses

PTC resettable fuses can be used in a wide range of applications. They have proven to be reliable solutions for protecting a variety of electronic components and devices from potentials for destructive over-currents as well as providing a means of resetting the device once across threshold has been exceeded. By providing a resetting feature, these fuses help to minimize any potential downtime due to critical faults.

The specific 0ZCK0035FF2G device belongs to the PTC resettable fuse family and is designed to provide over-current and temperature protection for circuits up to 12A. This device is ideal for use in small electronic systems where space is limited. It comes in a compact package and its short surge capability makes it suitable for use in over-heated conditions.

Working Principle

PTC resettable fuses function in anext premised way which conceptually is based on a thermistor. The fuse embeds a PTC (positive temperature coefficient) thermistor. This thermistor has a low resistance (or high electrical conductivity) when the ambient temperature is low, and a high resistance (or low electrical conductivity) when the ambient temperature is high. In the case of the 0ZCK0035FF2G, this works by detecting temperature levels as set- in this case, 12A. If the load current exceeds this max rating, it will trigger a temperature rise in the PTC thermistor.

Once triggered, the thermistor enters into its high resistance state and blocks the current from flowing. This will effectively cut the power reaching the device, and, provided the cause of the overload was eliminated, the fuse will reset itself, and the power supply will be restored.

Applications

The 0ZCK0035FF2G PTC resettable fuse can be used in a range of applications where limited space is a priority. It is especially suited to power supplies, battery charging applications, portable electronic and mobile device instances. It can also be used in low voltage automotive circuit boards, as well as those found in industrial and medical equipment.

It can be used in conjunction with other electronic components such as voltage regulators and is rated for ECO-friendly, lead-free soldering applications which comes in handy when providing essential protection for applications involving lead-free assemblies.

Conclusion

The 0ZCK0035FF2G PTC resettable fuse provides reliable and easy to use over-current and temperature protection for circuits up to 12A. It is a fuse suitable for use in electronics, power supplies, battery charging, and other applications which award a high priority to space constraints. Its resetting feature make it ideal for use in any equipment as it reduces any potential downtime due to critical faults.
