Product Overview

The S1N31Y5100NA4 is a mechanical enclosure that securely houses a standard SFP transceiver module on a printed circuit board (PCB). Its key design feature is the press-fit grounding pin, which provides a robust and reliable electrical path to the system chassis, improving EMI/RFI shielding and overall signal integrity in networking equipment.

Product Specifications / Attributes

  •  Form Factor: SFP
  •  Port Configuration: 1x1 (Single Port)
  •  Mounting Type: Through Hole
  •  Grounding Pin Type: Press-Fit
  •  Compliance: RoHS Compliant
  •  Material: Copper Alloy (Thickness: 0.25mm, Ni-Plated)
  •  Operating Temperature Range: -55°C to +85°C
  •  Packaging: Tray Packaging. Standard shipment includes 352 pieces per outer box, with 8 pieces per tray.

Features&Benefits

  •  Enhanced Grounding: The press-fit grounding pin ensures a stable and low-resistance connection to the chassis, crucial for EMI control.
  •  Secure Retention: Provides firm mechanical hold for the SFP module.
  •  Standard Compatibility: Designed to fit industry-standard SFP transceivers.
  •  Robust Construction: Made from nickel-plated copper alloy for durability and effective shielding.
  •  Manufacturing Friendly: SMT design is suitable for automated assembly processes. 

Applications

This component is used in networking hardware requiring SFP interfaces with robust EMI performance, such as:

  •  Enterprise and Data Center Switches
  •  Routers
  •  Network Interface Cards (NICs)
  •  Media Converters

Frequently Asked Questions (FAQ) 

Q1: What is the main difference between this model (S1N31Y5100NA4) and a similar SFP cage without a press-fit pin?

A1: The primary difference is the inclusion of a press-fit grounding pin. This pin is designed to be pressed into a plated through-hole on the PCB, creating a superior mechanical and electrical ground connection compared to solder tails alone, which enhances electromagnetic compatibility (EMC). 

Q2: What is the recommended PCB layout consideration for the press-fit grounding pin?

A2: The PCB must have a correctly sized plated through-hole to accept the press-fit pin. The technical drawing for this product specifies the required hole size and tolerance. It is also recommended to follow the provided guidelines for bezel opening and keep-out areas around the cage footprint for optimal performance.

Q3: What is the packaging quantity for a standard order?

A3: The product is shipped in trays. A standard order box contains 352 pieces, packaged with 8 pieces per tray.
