## Description
The 10039851-101LF is a right-angle header from Amphenol's AirMax VS® series of shieldless backplane interconnects, designed for high-density, high-speed differential signaling in telecom, networking, server, and storage applications. This 4-wall header configuration mates with vertical receptacle 10043546-101LF to form an 18-differential-pair connection (3 pairs per column × 6 columns) with 2mm column pitch. The connector employs edge-coupled differential pairs with air dielectric between adjacent conductors, achieving 100Ω ±8Ω differential impedance at 50ps rise time and supporting data rates up to 12.5Gb/s with insertion loss below 1.5dB and multi-active near-end crosstalk better than -28dB.
Constructed with copper alloy contacts featuring performance-based plating over nickel at separable interfaces and tin over nickel on press-fit tails, the module utilizes high-performance thermoplastic housings rated UL94V-0. The open pin field design eliminates pre-assigned ground pins, enabling flexible mixing of differential pairs, single-ended signals, power, and control lines within the same connector module. With a 3mm column pitch option available in the broader product family, designers can route two differential pairs between columns to reduce PCB layer count and system cost. The compliant press-fit termination supports vertical header, right-angle header, and right-angle receptacle configurations with maximum insertion forces of 40N for headers and 25N for vertical receptacles.
Rated for 0.5A per contact with all contacts powered (≤30°C temperature rise in still air) and contact resistance ≤35mΩ initial (≤10mΩ increase post-environmental testing), this connector meets Telcordia GR-1217-CORE Central Office requirements. The 200-cycle durability rating and backward-mating-compatible interface ensure long-term reliability and design flexibility across backplane, midplane, coplanar, orthogonal, cabled backplane, and mezzanine architectures. Packaged in tubes for automated assembly, the AirMax VS® series delivers cost-effective high-performance interconnect without the weight, complexity, and expense of shielded alternatives.

**BACKPLANE CONNECTORS**
## **AirMax VS[®] BACKPLANE/MIDPLANE CONNECTORS**
## **OVERVIEW**
The AirMax VS[®] connectors use innovative edge-coupling and air dielectric between adjacent conductors to deliver insertion loss and crosstalk. This technology, invented by FCI, enabled low cost, high performance connectors that are a leading backplane interconnect solution for telecom, networking, server, and storage applications.
The shieldless Open Pin Field Design with no pre-assigned ground pins provides the ultimate flexibility in board layout. The AirMax VS[®] connectors addresse a broad range of system architectures, including backplane, midplane, coplanar, midplane orthogonal, cabled backplane, and mezzanine applications.
This is a broad, high volume product family that system continues to earn business when competing with the many more expensive and complex shielded connector systems. This is due in part because of its high density, simple modular construction and low cost.
Further enhancements of the AirMax[®] product family are seeing speeds increase up to 25Gb/s, enabling customers to design electronic systems that are highly functional and cost effective. This enables backward compatibility with legacy systems and forward compatibility with the most advanced designs.
## **FEATURES**
- Innovative shieldless design and air dielectric between adjacent conductors
- Open Pin Field Design
- Connector available in modules with 3, 4, or 5 pairs per column and 6, 8, or 10 columns per module. 85 ohm versions also available
- Backward mating-compatible interface
- AirMax signal, power, and guidance modules in stock at most distributors
- Available with headers or receptacles on the backplane
- Adopted by multiple industry standard architectures, including Storage Bridge Bay and Serial CPCI
- Innovative shieldless edge couple technology and air dielectric between adjacent conductors
## **BENEFITS**
- Reduces cost, improves flexibility and delivers low insertion loss and crosstalk
- Allows mixing of differential pair signals, single ended signals, power and control lines within a standard connector module
- Enables system configuration using common, off-theshelf modules
- Simplifies design, supply chain management, inventory, and scheduling
- Allows designers to choose the right combination for any specific system using common components, reducing cost and lead times
- Assurance of supply, short lead times, and competitive pricing all reduce risk to the OEM and contract manufacturers
- Reduces connector cost, weight, and PCB routing complexity
- Standard configuration and part numbers accelerate your design and reduce risk
- 3mm pitch between columns enables two different pairs to route between columns, reducing board layer count, complexity, and system cost
