10123921-A70LF

Overview

The Amphenol ICC (FCI) part number 10123921-A70LF is a PCI Express Mini card edge connector designed for surface-mount or through-hole integration. It features a dual-sided female contact configuration with 52 positions, accommodating a card thickness of 0.031 inches (0.80mm). The contacts are gold-plated to ensure reliable signal transmission and corrosion resistance in demanding electronic environments.

Feature Summary

• Dual-sided female contact design for secure PCI Express Mini card retention
• Gold-plated contacts to maintain signal integrity and prevent oxidation
• Optimized for 0.031-inch thick cards ensuring precise mechanical alignment

Applications

• PCI Express Mini card slot interfaces
• Wireless communication module connections
• Solid-state drive expansion slots
• Industrial control system I/O modules

Procurement Notes

Verify the specific suffix A70 against the manufacturer's latest datasheet to confirm pinout orientation and mounting style compatibility. Ensure the receiving PCB footprint matches the 52-position dual-edge specification. Cross-reference the card thickness requirement of 0.031 inches with the target application hardware to guarantee proper mechanical fit and electrical contact pressure.

Selection Notes

Select this component when designing for PCI Express Mini form factors requiring robust dual-edge connectivity. The gold finish is suitable for applications needing long-term reliability without frequent mating cycles. Consider the 52-position count to ensure sufficient I/O lines for the specific peripheral interface requirements.

Part Context

This connector belongs to the high-density interconnect portfolio of Amphenol ICC (FCI), formerly FCI. The company specializes in board-to-board and card edge solutions for data processing and telecommunications.
