SMA R/A PCB Jack

Category: Amphenol Corporation, Connectors, Electronics

Overview

The datasheet details the specifications and features of the SMA Right Angle (R/A) Printed Circuit Board (PCB) Jack, identified by item number, drawing number, and part number 901-143-3. The datasheet includes a customer outline drawing with its other sheets intended only for internal company use unless specified otherwise.

Materials and Finishes

The components of the SMA R/A PCB Jack comprise materials including stainless steel and beryllium copper (BeCu) with gold plating for the body and contacts, respectively, and PTFE (Polytetrafluoroethylene), natural, for the insulators.

Electrical and Mechanical Specifications

The electrical impedance of the jack is specified as 50 Ohms. For mechanical durability, it is rated for a minimum of 500 cycles. Additionally, it has a temperature range from -65°C to +165°C, with certain dimensions such as 0.64 mm (0.025 inches) reference and a thread size of 14-36UNS-24. The packaging requirement specifies a single pack marked with “Amphenol RF”, the part number 901-143-3, and the date code.

Interface Standard

The jack interface conforms to the MIL-STD-348 series for SMA jacks, ensuring compatibility with military-standard SMA connectors.

Recommended Mounting

The datasheet provides recommended mounting hole dimensions, emphasizing the 1.27 mm (0.050 inches) reference as an important specification for proper installation.

Dimensions and Tolerances

The datasheet specifies that dimensions are metric with various tolerances ranging from ±0.05 mm to ±3 mm for different measurement ranges. Tolerances for angles are also provided to ensure precision during manufacturing and assembly processes.

Revision History and Approval

The document includes a revision history noting changes such as drawing redraft in a different software (Pro-E), sheet addition, and product release dates, with the latest approval on June 9, 2015, by S. Hsieh. The component was drawn by Arun Pradu and the title specified as “SMA R/A PCB Jack”.

Regulatory and Legal Information

The datasheet concludes with a notice that the drawings and specifications are proprietary to Amphenol RF, with a strict prohibition on disclosure unless authorized by Amphenol Corporation. It indicates legal guidance by referencing EAR 1-961820 and other Alcatel configuration levels.
