Introduction to 16R900GMR:
The 16R900GMR is a resettable PTC fuse which is an overcurrent protection device and part of the RDT product family of Resettable Device Technology from Microsemi Corporation. It is designed to limit the current the device will draw during overcurrent or overvoltage conditions.

Characteristics of 16R900GMR:
The 16R900GMR offers several features, such as a low resistance, up to 1.1 Ω; high surge current capability; improved thermal dissipation; and a wide operating temperature range to ensure steady performance even in extreme temperatures. This device is designed to withstand overvoltages up to 32 V and has a high interrupting rating of 10A. The 16R900GMR also has a fast response time and is capable of performing multiple resets under extreme conditions.

Applications of 16R900GMR:
The 16R900GMR is mainly used in power supply systems, motor and valve control systems, LED lighting, automotive electronics, and communication systems. It can also be used for switch mode supplies, residential and commercial lighting systems, industrial controls and systems, Internet of Things (IoT), medical devices, home automation, and entertainment systems.

Working Principle of 16R900GMR:
The 16R900GMR works in a manner similar to a resettable thermal fuse. It uses a positive temperature coefficient (PTC) element of polymeric material to sense current flow through it. The PTC element increases the resistance when current rises above the trip level, causing the device to overheat and open the circuit. The 16R900GMR reset automatically when currents decreases to the specified level and temperature is below a certain threshold. The PTC element maintains a high resistance state until it is reset manually.

Conclusion:
The 16R900GMR is an ideal product for protecting circuits against overcurrent and overvoltage conditions. Their fast response time and resettable feature make them suitable for applications in power supply systems, automotive electronics, industrial controls and systems, and LED lighting. The 16R900GMR works in a manner similar to a resettable thermal fuse using a polymeric based PTC element to sense current flow through it.
