PTC Resettable Fuses, also known as Polymer Positive Temperature Coefficient (PPTC), are self-resetting, self-regulating, and designed to protect electronic components from over-current and short-circuit damage. The TRF600-150-B-0.5 is a surface-mounted PPTC designed to provide reliable over-current protection in a wide variety of applications. It is ideal for current-limiting use in industrial and consumer electronic products.

Application Field

The TRF600-150-B-0.5 is a versatile PPTC ideal for providing over-current protection in modern consumer and industrial electronics. Its robust construction and the ability to self-regulate to the appropriate current limit make it ideal for use in a wide variety of applications such as appliances, HVAC, lighting, communications, transportation, and other industrial applications that rely on electronic components.

In addition to protecting against over-current and over-voltage, the TRF600-150-B-0.5 is a self-resetting device, which means that it automatically kicks back into protection mode following an over-current event. This feature eliminates the need for manual resetting and downtime associated with traditional fuses.

The TRF600-150-B-0.5 is suitable for use in a wide variety of operating environments and temperature ranges from -40°C (~-40°F) to +85°C (~185°F). It is UL Recognized, RoHS Compliant, and meets industry standards for over-voltage and over-current protection.

Working Principle

The TRF600-150-B-0.5 utilizes a special thermoplastic elastomer material (polymer) that acts like a resistor. It has two "wires" that are connected in series and the polymer material is placed between them. As the requirement of electric current increases, the polymer in the resistor gets heated and changes its resistance to a higher setting, causing an impedance increase in the circuit. This impedance limits the current flow and therefore prevents damage due to over-current and short-circuits.

When there is a decrease in current flow, the polymer material returns to its original state, creating a low resistance path and allowing current to flow. This repeatable cycle of current interruption and return allows the TRF600-150-B-0.5 to provide reliable protection in a wide variety of applications.

The TRF600-150-B-0.5 is a reliable and cost-effective solution for over-current protection. Its self-regulating and self-resetting properties make it ideal for use in a wide variety of applications. Thanks to its robust construction and wide temperature range, the TRF600-150-B-0.5 can provide reliable protection for years to come.
