PTC Resettable Fuses

PTC Resettable Fuses are designed to provide reliable, non-destructive protection of electrical circuits. They provide reset circuit protection over-current or short circuit situations. PTC resettable fuses are an ideal solution for applications where traditional fuses are more likely to be damaged due to their large size and short circuit interrupting capability. One example of these applications is 1210L110THYR.

1210L110THYR Application Field and Working Principle

The 1210L110THYR PTC Resettable Fuse is a high precision, low power, durable and efficient protection device, which utilizes an NTC thermistor for over-current or short circuit protection. It is a two-pin PTC resettable fuse with a current rating of 110mA. Application in over-current protection requires a short-circuit current to reach a certain value or time, the resistance of the fuse rapidly increases and the current shuts down. Once the fault or overload is eliminated, the fuse resets itself and resumes normal operation.

This type of PTC resin fuse has broad application fields, such as DC/AC motors, DC/AC LED lights, transformer, and small electrical appliances. Due to its reliable performance, PTC resettable fuses can also be used in presence of high humidity environment, such as in power tools, battery powered equipment, lighting, charging circuits, switch control units, and communication equipment.

The 1210L110THYR PTC Resettable Fuse utilizes an NTC thermistor as its working element that is integrated into the fuse to detect current. Its operational temperature range is -40°C to 85°C. It has a rated current of 110mA and a rated voltage of 32VDC. The fuse has a fast response time and is designed to detect current up to 30V. Due to its small size, it is suitable for use in compact electronics.

In applications requiring resistance to high levels of voltage, current, or both, 1210L110THYR PTC Resettable Fuse is a superior choice. It is designed to be highly reliable and can withstand rapid current surges and withstand high levels of electric shock. It is also capable of protecting against momentary and/or destructive conditions. Its response time is immeasurably fast, and it is designed to work within a wide temperature range.

The 1210L110THYR PTC Resettable Fuse is a reliable, non-destructive circuit-protection device designed to provide reliable and long-lasting protection of electrical circuits. Its low power, robust construction and fast response time make it a desirable solution for protection applications involving high levels of voltage, current, or both. Its small size and wide operational temperature range make it ideal for use in a wide range of electronic applications.
