91901-31215LF

Rectangular connectors – arrays, edge type, mezzanine (board to board) – are essential components of many electronic systems. The 91901-31215LF is a two-row variant of these components, featuring two rows of signal contacts and 10 pins along with a mounting flange located at the rear for secure installation. It is suited to applications such as modern computing platforms, data centers, military/aerospace, and communications systems.

The 91901-31215LF uses 256 mil spacing for signal connections, making it a viable choice for dense signal application environments. With an operating temperature range of -55C to +125C, the 91901-31215LF is designed for a wide range of applications in challenging environments. It also offers good electrical performance, with a 0.1 ppb rating for crosstalk, and high current ratings that accommodate heavy-duty applications.

The two rows of signal contacts in a 91901-31215LF feature both male and female in-line connectors. The connectors use a friction-lock connection mechanism to ensure a snug fit, with a breakaway tab for easy removal. The connectors are compliant with several major standards, including MIL-STD-1760, IEC 60204-3, and IPC/JEDEC-J-STD-20. The connector\'s mounting flange is designed to conform to accepted EMC shielding requirements.

The 91901-31215LF is constructed with a copper alloy shell and contacts for maximum durability and reliability. The contacts are gold-plated to help prevent corrosion and ensure a low-resistance connection. To ensure a robust connection, the contacts in the array are designed to spread the stresses of the connection over a larger area. This helps to reduce the risk of vibration-related cable failure.

Since the 91901-31215LF uses a metal shell and contacts, it\'s important to consider any EMI emissions that may occur due to the connection. The shield on the 91901-31215LF helps to reduce or eliminate EMI, making it suitable for use in environments with stringent EMI requirements. The connector is also designed to be resistant to damage from shock and vibration.

The 91901-31215LF is well suited to applications that require a reliable connection between two printed circuit boards. The two rows of signal contacts in the array are designed to spread the stresses of the connection over a larger area, making it less vulnerable to damage from vibration. Additionally, the high current ratings and EMI shielding make it suitable for a range of high-performance applications. With its robust construction and versatile design, the 91901-31215LF is an excellent choice for both commercial and military/aerospace applications.
