1812L150/12DR

The "1812L150/12DR" is a specific component manufactured by Littelfuse Inc., known for its expertise in circuit protection and electronic components. This part is a type of fuse, specifically designed to provide overcurrent protection in various electronic applications.

Detailed Description:

1. Form Factor:

   • The "1812" in the part number indicates the physical dimensions of the fuse. It typically measures 0.18 inches by 0.12 inches (4.57 mm x 3.18 mm), which is a standard size for surface-mount devices (SMD). This compact form factor allows for easy integration into printed circuit boards (PCBs) without taking up excessive space.

2. Type:

   • The "L" in the part number signifies that this is a low-profile fuse, which is advantageous for applications where height restrictions are a concern. Low-profile fuses are designed to fit into tighter spaces while still providing reliable protection.

3. Current Rating:

   • The "150" indicates the current rating of the fuse, which is 150 mA (milliamps). This rating specifies the maximum continuous current that the fuse can handle without blowing. It is crucial for ensuring that the fuse will protect the circuit from overcurrent conditions without interrupting normal operation.

4. Voltage Rating:

   • The "12" in the part number typically refers to the voltage rating, which is 12 volts. This means the fuse is designed to operate safely at voltages up to 12V, making it suitable for low-voltage applications.

5. Material and Construction:

   • The fuse is usually constructed from a combination of metal and ceramic materials, which provide durability and reliability. The internal element is designed to melt and break the circuit when the current exceeds the rated limit, thus protecting downstream components from damage.

6. Applications:

   • The 1812L150/12DR fuse is commonly used in various electronic devices, including consumer electronics, automotive applications, and industrial equipment. It is particularly useful in circuits where space is limited and where overcurrent protection is critical to prevent damage to sensitive components.

7. Performance Characteristics:

   • The fuse is designed to have a fast-acting response, meaning it will blow quickly in the event of an overcurrent situation. This characteristic is essential for protecting sensitive electronic components that could be damaged by even brief overcurrent conditions.

8. Compliance and Standards:

   • Littelfuse products typically comply with various industry standards and regulations, ensuring that they meet safety and performance requirements. This compliance is crucial for manufacturers looking to meet regulatory standards in their products.

9. Packaging:

   • The fuse is usually available in tape-and-reel packaging, which facilitates automated assembly processes in manufacturing environments. This packaging method allows for easy handling and placement on PCBs.

In summary, the Littelfuse 1812L150/12DR is a low-profile, surface-mount fuse designed for overcurrent protection in compact electronic applications. Its specifications make it suitable for a wide range of uses, ensuring the safety and reliability of electronic circuits.
