The 2920L400/15MR is a type of timing belt known for its specific dimensions and features. It is part of the 2920 series, where "L" indicates the belt's tooth profile, specifically a trapezoidal tooth shape, suitable for light to medium load applications. The "400" signifies the belt's length in inches, which is crucial for compatibility with specific machinery. The "/15MR" can imply additional specifications or a part of the manufacturer's coding to denote particular design features or construction materials, such as enhanced resistance to wear, oil, or temperature, although specific details would require referencing the manufacturer's datasheet.
Typically, timing belts like this are used in synchronous drive systems, ensuring accurate timing between the driver and the driven components. These belts are essential in reducing slippage and maintaining precise mechanical synchronization, often used in automotive engines, printers, and conveyor systems. The material construction, such as rubber or polyurethane with embedded tensile fibers, contributes to its strength and durability. Always consult the manufacturer's specifications for detailed features and compatibility.

The 2920L400/15MR is a PolySwitch resettable PTC (Positive Temperature Coefficient) device manufactured by Littelfuse. It is designed to protect electronic circuits from overcurrent conditions. The "2920" in its name refers to the device's dimensions (in mils), not its pin count, as it is a surface-mount component.
The 2920L400/15MR does not have traditional pins, as it is a surface-mount device (SMD). Instead, it features two terminals or pads for soldering onto a circuit board. Its primary function is to limit current flow in electronic devices by increasing its resistance sharply when the current exceeds the threshold, thereby protecting the circuit from damage.
Key specifications include:
- Hold Current (I_hold): 4.0A
- Trip Current (I_trip): 8.0A
- Voltage Rating (V_max): 15V
- Maximum Fault Current: 100A
This device is commonly used in applications requiring overcurrent protection, such as in USB ports, telecommunications, and consumer electronics.
