PTC Resettable Fuses

PTC resettable fuses are electronic components that can protect high-alpha circuits from overcurrent and overvoltage. They consist of a PTC (positive temperature coefficient) element, which is a polymer semiconductor material that increases in overall resistance as temperature rises, and an electronic control circuit, which is typically a voltage limiter or fuse controller. When the current or voltage passing through the PTC element exceeds the pre-set values, the resistance of the PTC element increases and the current or voltage is cut off.The PTR016V0800-BK is a resettable fuse designed for use with electronic equipment that requires over-current and over-voltage protection. It is a type of polymeric positive temperature coefficient (PPTC) resettable fuse, which is a field-effect transistor (FET)-based PTC element. When over-current or over-voltage protection is required, the PTR016V0800-BK will reset itself after a predetermined overcurrent or overvoltage event.The PTR016V0800-BK is a self-resetting, surface mount, radial leaded fuse, and is RoHS compliant. It has a current rating of 0.8A, a voltage rating of 16V, and a hold current of 0.4A. It has a total diameter of 4.7mm, and a resistance of 30 ohms at room temperature. The PTC element is specifically designed for low circuit dropout voltage, low loss, and a high operating temperature range.The PTR016V0800-BK is typically used to protect circuits from over-current and over-voltage events. It is especially suitable for use in automotive, medical, consumer electronics, and industrial applications. It is often used to protect a wide variety of components from over-current, over-voltage, short-circuits, and other critical conditions, such as motors, power supplies, and LEDs. The PTR016V0800-BK can also be used to protect control systems and other sensitive equipment from accidental damage caused by over-current or over-voltage events.The working principle of the PTR016V0800-BK is based on the FET-based PTC element. When the voltage or current passing through the PTC element exceeds a predetermined amount, the temperature of the PTC element increases and the resistance increases accordingly. This causes the voltage or current passing through the PTC element to be cut off, thus protecting the circuit from further damage. When the temperature of the PTC element drops below a predetermined threshold, its resistance returns to its initial state and the circuit is reset, thus allowing the system to run again safely.In summary, the PTR016V0800-BK is a PTC resettable polymeric fuse with a current rating of 0.8A, a voltage rating of 16V, a hold current of 0.4A, and a total diameter of 4.7mm. It is mainly used to protect circuits from over-current and over-voltage events, and is suitable for use in automotive, medical, consumer electronics, and industrial applications. Its working principle is based on the FET-based PTC element, which spontaneously opens the circuit when the voltage or current passing through the PTC element exceeds a predetermined amount.
