PTC Resettable Fuses serve their purpose of protecting electrical circuits from damage and are becoming popular as a safety element in many applications including automotive and medical technology. The RTE190-2 series of Resettable Fuses typically features a low voltage drop, a low voltage rating, and a push to reset mechanism, making it suitable for many applications.

The RTE190-2 is a self-resetting thermal detector with a polymeric Positive Temperature Coefficient (PPTC) element. This element has an inherent resistive-capacitance circuit that detects an over-temperature condition and causes an instantaneous current response. The self-resetting element acts as a switch and disconnects the circuit when an over-temperature condition is detected. The RTE190-2 is rated for an operating temperature of between 32-105°C, with a 32-55°C operating temperature range for reset operation.

The circuit design eliminates the need for a separate circuit breaker. With a simple single push reset operation, the RTE190-2 can quickly be restored to its normal operating state. The solid state design of the RTE190-2 also offers greater noise immunity and enhanced protection for sensitive components. The design provides a fail-safe operation in the event of an over-temperature condition. By preventing the circuit from being overloaded, devices are able to remain in their optimal operating state.One of the primary advantages of the RTE190-2 series is its high reliability with the ability to reset up to 10,000 times without fail. The RTE190-2 series is also capable of providing superior arc suppression with its low voltage drop over a wide operating temperature range. It is capable of providing a 6V drop at 100mA and ensuring current stability by providing an arc-free operation. This feature increases component life while staying within the specified temperature ratings.

The RTE190-2 series is frequently used in applications that have a need for superior performance due to the high temperatures present. This includes applications in the medical field such as in MRI machines, as well as power applications and automotive applications. With its small size, the RTE190-2 series can be easily integrated into various types of equipment. This level of versatility makes it suitable for a wide range of applications. The RTE190-2 series provides a number of benefits when it comes to energy efficiency and cost savings. By regulating the amount of power that is used in the circuit, it can help reduce electrical costs and reduce energy consumption. Additionally, it prevents damage to sensitive components which can increase overall system reliability. This helps ensure that products and systems last longer and provide a better return on investment. Overall, the RTE190-2 series of Resettable Fuses provides a reliable and cost-effective solution for many applications. With its low voltage rating and low voltage drop, the RTE190-2 series provides superior performance as well as superior protection for devices and components. It also offers an increased level of reliability, a 50,000 cycle count life time, and a 6V drop at 100mA, making it one of the most versatile and reliable devices on the market.
