PTC Resettable Fuses: 0805L175SLYR application field and working principle

PTC Resettable Fuses, or Polymeric Positive Temperature Coefficient Resettable Fuses, are small devices which protect electrical circuits from over currents, short circuits, and other related circuit faults. PTC Resettable Fuses have been used in a wide range of applications including electric and electronic appliances, power supplies, automotive electronics, telecommunications, medical equipment, aeronautic electronics, computer and data equipment, and consumer electronics. The 0805L175SLYR from Shenzhen ShineHe is a practical and cost-effective PTC Resettable Fuse that can withstand a wide range of temperatures, currents, and voltages.

Overview of the 0805L175SLYR

The 0805L175SLYR PTC Resettable Fuse is a surface mount device, with a single-in-line package. The device is a low-profile and cost-effective, resettable fuse solution for over-current protection. It has an operating voltage of up to 175VAC/DC ±20%, and is available in current ratings ranging from 5A to 25A rated current. The holds time at rated current is 0.025 seconds, while the trip time at 100% overload is less than 5 seconds. The device has a maximum working temperature of 125ºC and temperature coefficient of -50ºC to +105ºC. The device also has a high temperature burnout property, protecting against short circuit faults.

Overview of Working Principle

PTC Resettable Fuses work on the principle of Polymeric Positive Temperature Coefficient (PPTC) technology. The 0805L175SLYR has an integrated PPTC element in a laminate housing. The PPTC element is a film type device designed to cut off current when the temperature of the element rises above a predetermined level. This increase in temperature occurs when the current exceeds a maximum level, set by the manufacturer. The PPTC element then develops a very high electrical resistance, effectively cutting off the flow of current. This protects the circuit from the effects of short circuits, in-rush currents, and surges. The resettable nature of the 0805L175SLYR ensures that when the current is restored to a safe level, the PPTC element will reset itself and return to its low resistance state, allowing the circuit to be restored.

Applications

The most common applications for the 0805L175SLYR are over-current protection in electronic appliances, power supplies, and industrial equipment. The device can be used as a part of an over-voltage protection circuit and can be used to prevent destructive current overshoots from occurring in wind turbines, solar panel systems, and other applications requiring high voltage protection. The device is also suitable for use in automotive, IT, and consumer electronics applications, providing reliable over-current and surge protection.

Conclusion

The 0805L175SLYR PTC Resettable Fuse from Shenzhen ShineHe is a low-cost, high-performance device with an operating voltage of up to 175VAC/DC ±20%, and available in current ratings ranging from 5A to 25A. The device is quick to restore when current is reduced to a safe level, and is suitable for use in automotive, IT, and consumer electronics applications. The 0805L175SLYR provides reliable over-current and surge protection, protecting circuits from short circuit faults, in-rush current, and overvoltage.
