PTC Resettable Fuses are key components used in printed circuit boards for protecting electronic products from overcurrent. Due to their simplicity, reliability and cost-effectiveness, they have become increasingly popular for a variety of electronic components and applications. 20LR600SU is one such PTC Resettable Fuse designed to provide reliable overcurrent protection while also reducing downtime and costs associated with damaged components.

The 20LR600SU is a single-ended PTC resettable fuse, designed using a positive temperature coefficient (PTC) thermistor. It contains a PTC element, a trigger current level, internal insulation and a metal housing. A PTC element works by abruptly increasing resistance when the current passing through it exceeds its rated operating current. This increase in resistance protects circuits from damaging overcurrent events. The internal insulation prevents high voltage differentials from leaking through and damaging the sensitive components in the circuit.

The 20LR600SU\'s PTC element is able to detect when the current passing through it surpasses its rated capacity, and triggers a characteristic resistance (constant current) with an up-ramping, limited time-of-day pattern. This improves protection while minimizing nuisance trips, increasing system uptime and reducing maintenance costs. The 20LR600SU utilizes a low-profile metal housing making it ideal for use in space-constrained applications.

The 20LR600SU is suitable for use in a variety of applications, including industrial, automotive, power supplies, solar systems, consumer electronics, and more. It is capable of providing overcurrent protection for a wide range of equipment and components, from batteries and DC motors to relays, electronic control units, and sensitive components. It can also be used in applications requiring frequent reset operations, such as automotive start-stop systems, energy management systems, and HVAC systems.

The 20LR600SU is a reliable and cost-effective solution for protecting equipment and components from overcurrent and short-circuit caused by faults or misuse in the circuit. With its low profile and reliable overcurrent protection, it is a popular choice for protecting circuits with sensitive components. In addition, its ability to reset itself rapidly and safely makes it an ideal choice for applications that require frequent reset operations, such as automotive start-stop systems, energy management systems, and HVAC systems.
