PTC Resettable Fuses and B59980C0080A051

PTC resettable fuses have been widely used to provide short circuit protection, over current protection and over temperature protection for a variety of applications such as consumer electronics, lighting, solar, automotive, and other industries. The B59980C0080A051 is a new generation of PTC resettable fuses specifically designed for high-speed current limiting applications. This application field presents unique technical challenges that the B59980C0080A051 is able to address.

Application Field

The B59980C0080A051 is particularly suitable for protecting high-speed cables, connectors, and components. It can be used in fast charging applications such as mobile phone chargers, USB chargers, and other consumer electronics. It\'s also suitable for automotive applications requiring high reliability such as chillers, compressors, vehicle DC/DC converters, headlight/interior lights, and more. The B59980C0080A051 is also suitable for simultaneous protection of multiple channels, such as LCD monitor connectors and cable crossovers.

Working Principle

The B59980C0080A051 uses a polymeric positive temperature coefficient (PPTC) material, which becomes increasingly resistant when subjected to current overload or higher temperatures. This makes it an ideal choice for modern high-speed applications where fast current limiting action is necessary. It also has two common operating modes: self-initiated Reset and Latch Reset.

In self-initiated reset, the device will immediately activate and reduce the current flow once it is overloaded. This reduces the risk of damage due to an unexpected and sudden current spike. It also reduces the risk of component failure from excessive current. In Latch Reset, the device latches into an open state when the current is overloaded and then resumes its normal functioning condition when the current returns to its normal level.

Conclusion

The B59980C0080A051 is a reliable and efficient PTC resettable fuse designed for high-speed current limiting applications. It can be used in a wide range of applications, from fast chargers and DC/DC converters to LCD monitors and multiple channel protection. It also has two popular operating modes, self-initiated reset and latch reset, which can effectively protect components in the event of an unexpected current spike or overload.
