EHF-125-01-L-D-SM-LC

The EHF-125-01-L-D-SM-LC is a specific connector product from Samtec, Inc., a well-known manufacturer of electronic interconnect solutions. This connector is part of the EHF series, which is designed for high-density applications requiring reliable performance in compact spaces.

Detailed Description:

1. Type and Configuration:

   • The EHF-125-01-L-D-SM-LC is a high-speed, low-profile connector designed for board-to-board applications. It features a dual-row configuration, which allows for a high number of contacts in a limited footprint.

2. Contact Arrangement:

   • This connector typically has 125 positions, arranged in two rows. The arrangement is designed to facilitate efficient signal transmission while minimizing the space required on the PCB.

3. Pitch:

   • The contact pitch (the distance between the centers of adjacent contacts) is usually around 0.80 mm, which is standard for high-density connectors. This tight pitch allows for more connections in a smaller area, making it ideal for modern electronic devices.

4. Mounting Style:

   • The "D" in the part number indicates that it is a surface mount connector. This means it is designed to be mounted directly onto the surface of a printed circuit board (PCB), which is a common practice in modern electronics for ease of assembly and space-saving.

5. Contact Material and Plating:

   • The contacts are typically made from high-conductivity materials, such as copper alloy, and are often plated with a layer of gold or nickel to enhance conductivity and prevent corrosion. This ensures reliable electrical performance over time.

6. Insulation Material:

   • The housing of the connector is usually made from a durable thermoplastic material that provides good insulation properties and mechanical strength. This material is often rated for high-temperature applications, ensuring that the connector can withstand the rigors of soldering and operation.

7. Operating Temperature:

   • The EHF-125-01-L-D-SM-LC is designed to operate within a wide temperature range, typically from -40°C to +105°C, making it suitable for various environments, including industrial and consumer electronics.

8. Applications:

   • This connector is commonly used in applications such as telecommunications, data communications, consumer electronics, and automotive systems, where high-speed data transfer and reliability are critical.

9. Additional Features:

   • The connector may also include features such as polarization to ensure correct mating, and it may be designed to support high-speed data rates, making it suitable for applications requiring fast signal transmission.

10. Compliance and Standards:

    • Samtec connectors often comply with various industry standards for quality and performance, ensuring that they meet the requirements for safety and reliability in electronic applications.

In summary, the EHF-125-01-L-D-SM-LC from Samtec, Inc. is a high-density, low-profile surface mount connector designed for reliable performance in compact electronic applications, featuring a dual-row configuration, high-speed capabilities, and robust construction materials.
