PTC Resettable Fuses, also known as polymeric positive temperature coefficient (PPTC) resettable fuses, are designed to protect and control electrical circuits against an excessive current. They have a fast acting current-limiting function which avoids circuit damage and prevents fire risks. This type of fuse is a popular choice for commercial and household electronics, automobiles, and other mission-critical applications.

The PTC Resettable Fuses are made of special dielectric polymers, such as polyethylene (PE) and ethylene propylene diene monomer (EPDM). These polymers can withstand higher temperatures compared to traditional ceramic-based fuses and have superior resistance to age-related defects, such as creeping, moisture, and chemical damage. Furthermore, the PTC Resettable Fuses offer high dielectric strength, low-resistance contact areas, and a reliable electrical performance.

The PTGL7SAS3R3K3B51A0 PTC Resettable Fuses are designed with high-quality and long-life adhesives, which makes them suitable for a variety of applications including those involving high-temperatures. These fuses also come with a grooved end plug, so they can be easily connected to the circuit board. The PTGL7SAS3R3K3B51A0 PTC Resettable Fuses have a high melting temperature of 510 degrees Celsius (950 degrees Fahrenheit) and are UL-rated and CSA-approved to ensure safety and reliability.

The PTGL7SAS3R3K3B51A0 PTC Resettable Fuses are available in a variety of current ratings from 0.1A to 15A making them well-suited for a wide range of applications. They have a tight hold-back and ultra-fast trip response time, with a release time of less than 1 second. Furthermore, the adjustable trip current characteristics allow the user to set the trip current as needed. The PTC Resettable Fuses also feature a unique internal thermal resistance compensated baseplate construction which ensures reliable trip performance at both high and low temperatures.

The working principle of the PTGL7SAS3R3K3B51A0 PTC Resettable Fuses is relatively simple. When the current through the fuse exceeds the preset trip current value, the heat generated by the resistance in the fuse will cause its polymeric material to melt and create a conductive path. This will reduce the current to a safe level, and the fuse will reset automatically when the temperature drops below the melting point.

This type of fuse is ideal for use in devices where continuous current monitoring is required, or when other fuses fail due to repeated currents exceeding their maximum rating. The PTGL7SAS3R3K3B51A0 PTC Resettable Fuses are also often used to protect circuits from current surges due to lightning and other transient factors. They can be used in applications like power supplies, audio amplifiers, computer peripherals, and more.

The PTGL7SAS3R3K3B51A0 PTC Resettable Fuses are perfect for ensuring the safety and reliability of electrical circuits and equipment, with their fast-acting current-limiting function. They are highly reliable and can be used in a wide variety of applications.
