Introduction to PTC Resettable Fuses

PTC (Positive Temperature Coefficient) Resettable Fuses are a type of electrical protection devices that are designed to open when an over-current or short-circuit condition is present in the application. These devices automatically reset, allowing the circuit to continue functioning without waiting for replacement.

The working principle of PTC Resettable Fuses begins with the current-sensing element configured to the coil. When a short-circuit or over-current condition occurs, the current exceeds the value set by the device sensitivity, resulting in a voltage generated in the coil. This voltage causes the PTC fuse to open, breaking the circuit and protecting from over-current.

The PTC fuse will remain open until the over-current or short-circuit condition is cleared. Once this is accomplished, the PTC fuse will automatically reset itself, allowing the circuit to remain energized and functioning.

The B59850C0080A070 application field and working principle

The B59850C0080A070 is an ultra-low-resistance PTC Resettable Fuse ideal for consumer and mobile application over-current protection requirements. This device is designed to open and protect the circuit from over-current conditions.

The working principle of the B59850C0080A070 device is similar to other PTC resettable fuses. When an over-current or short circuit condition is present in the application, the current level exceeds the device sensitivity and voltage is generated in the coil. This voltage then causes the fuse to open, protecting the circuit from the over-current or short circuit.

The B59850C0080A070 device is designed with a resetting current value of 0.6 A, making it an ideal solution for mobile and consumer applications requiring ultra-low resistance. Additionally, the device has a high voltage rating of 16 V, a power rating of 450 mW, and a rated current of 1.8 A.

The device features an operating temperature range of -20°C to +85°C, making it suitable for a wide range of environmental conditions. Additionally, the device is RoHS compliant and lead-free in accordance with JEDEC standards, making it an environmentally friendly solution that can be used in a variety of applications.

In conclusion, the B59850C0080A070 PTC Resettable Fuse is an ideal solution for applications requiring ultra-low resistance, over-current protection, and environmental compliance. When an over-current or short-circuit condition occurs, the device is designed to open, protecting the circuit while also automatically resetting itself when the fault condition is eliminated.
