Pptc fuse

A resettable fuse or polymeric positive temperature coefficient device PPTC is a passive electronic component used to protect against overcurrent faults in electronic circuits. Pptc fuse device is also known as a multifuse or polyfuse or polyswitch.

These components remove the need for any temperature-based nuisance tripping across all such applications, while offering increased, high resistance protection in space-saving surface mount packages. A wider selection of applications include: automobile circuitry protection, overcurrent surge protection of high reliability electronic equipment, robust resettable fault protection for industrial transportation, communication, security, and consumer electronic equipment.

Capacitors boosts the current and increases the power factor to an electrical motor. Search for the part s number you wish to receive samples. Or, visit the sample center page. PPTCs increase resistance as temperature increases due to increased flow. Designed to limit unsafe currents while allowing constant safe current levels, resistance will "reset" automatically when the fault is removed and temperature returns to a safe levels. Surface mount resettable PPTC devices provide overcurrent protection for applications where space is at a premium and resettable protection is desired. Package size varies from to , while hold current ranges from 50mA to 7. Radial leaded resettable PPTCs are designed to provide overcurrent protection for applications where space is not a concern and resettable protection is preferred. Battery strap resettable PPTCs provide reliable, non-cycling protection against overcharging and short circuits events for rechargeable battery cells where resettable protection is desired. The Telecom resettable PPTC Series is designed to protect against short-duration high-voltage fault currents power cross or power induction surge typically found in telecommunications and networking applications. Traditional Fuses vs. Understanding the differences between the two technologies should make the choice in selection easier, depending on the application. The most obvious difference is that PPTCs are automatically resettable whereas traditional Fuses need to be replaced after they they are tripped. Whereas a fuse will completely stop the flow of current which may be desired in critical applications after most similar overcurrent event, PPTCs continue to enable the equipment to function, except in extreme cases.

While cold, the polymer is in a crystalline state, pptc fuse, with the carbon forced into the regions between crystals, forming many conductive chains. Fuses do in fact interrupt the current flow in response to the overload and the range of interrupting ratings, vary from tens of amperes A up to 10, A amperes at rated voltage.

A polymeric positive temperature coefficient device PPTC is a passive electronic component used to protect against overcurrent faults in electronic circuits. Simply put, a PPTC device, also known as a multifuse or polyfuse or polyswitch, is actually a resettable fuse! Positive temperature coefficient PTC resettable fuse is a circuit protection device which provides overcurrent and overtemperature protection in a variety of applications. A PTC resettable fuse can open electric circuits during fault events like a traditional one-time fuse, but is automatically resettable. A PTC fuse consists of a positive temperature coefficient material whose internal resistance increases exponentially with an increase in operating temperature. In the ON state tripped state , the device offers very high resistance in response to faults such as short-circuit or overheat, thus limits the current flow through the device until the material cools, then reverts to low resistance mode. In the OFF state idle state , the device maintains a low resistance as the current is within a safe range www.

While a fuse could also offer similar protection, if the fuse is blown, the tweeter cannot operate until the fuse is replaced. Provide a complete, one-piece solution for easy procurement and code compliance. Mounting Style. Leakage Current When a PPTC is in a "tripped state" it protects the circuitry by limiting the current flow to a low leakage level. Product Series. Work Phone. EC Circuit Protection of USB 2 0 This application brief demonstrates how to ensure reliable and safe circuit operation of USB products, protection against voltage and current transients must be carefully considered. PPTCs hold and trip rating must be rerated when applied at conditions other than room ambient. Search By Parameter.
