1210L005WR

The "1210L005WR" is a specific model of a fuse manufactured by Littelfuse Inc., a well-known company specializing in circuit protection and electronic components. This particular fuse is designed for use in various electronic applications where overcurrent protection is essential.

Detailed Description:

1. Type: The 1210L005WR is a surface mount fuse, which means it is designed to be mounted directly onto the surface of a printed circuit board (PCB). This type of fuse is ideal for modern electronic devices where space is at a premium.

2. Size and Form Factor: The fuse typically comes in a compact 1210 package size, which measures approximately 3.2 mm x 2.5 mm. This small form factor allows for efficient use of space on PCBs, making it suitable for applications in smartphones, tablets, and other compact electronic devices.

3. Current Rating: The "005" in the model number indicates that this fuse has a current rating of 5 Amperes. This means it is designed to carry a maximum continuous current of 5A before it will blow (open the circuit) to protect the downstream components from excessive current.

4. Voltage Rating: The fuse is typically rated for a voltage of 32V, making it suitable for low-voltage applications. This rating ensures that the fuse can safely interrupt the circuit without arcing or causing damage.

5. Material and Construction: The 1210L005WR is constructed from high-quality materials that provide reliable performance and durability. The fuse element is usually made from a metal alloy that melts when the current exceeds the rated value, effectively interrupting the circuit.

6. Operating Temperature: The fuse is designed to operate within a specified temperature range, typically from -55°C to +125°C. This wide operating temperature range ensures that the fuse can function effectively in various environmental conditions.

7. Features:

   • Fast-acting: This fuse is designed to respond quickly to overcurrent conditions, providing immediate protection to sensitive components.
   • RoHS Compliant: The 1210L005WR is compliant with the Restriction of Hazardous Substances (RoHS) directive, ensuring that it is free from certain hazardous materials, making it safer for the environment.

8. Applications: This fuse is commonly used in consumer electronics, automotive applications, telecommunications equipment, and industrial machinery. It is particularly useful in circuits where space is limited and reliable overcurrent protection is necessary.

9. Mounting: As a surface mount device (SMD), the 1210L005WR is soldered directly onto the PCB, which helps to reduce the overall height of the assembly and improve the reliability of the connection.

In summary, the Littelfuse 1210L005WR is a compact, reliable surface mount fuse designed for overcurrent protection in a variety of electronic applications. Its small size, fast-acting characteristics, and compliance with environmental standards make it a popular choice among engineers and designers in the electronics industry.
