M80-MV312M3-08

Overview

The M80-MV312M3-08 is a Datamate J-Tek coaxial connector header manufactured by Harwin Inc. It features eight male positions with a 4.00mm pitch, designed for vertical through-hole mounting. The component supports frequencies up to 6 GHz and maintains a 50 Ohm impedance characteristic. Contacts are gold-plated phosphor bronze housed in black glass-filled polyphenylene sulfide (PPS).

Feature Summary

• Integrated coaxial design supporting high-frequency signal transmission up to 6 GHz.
• Vertical surface mount orientation with through-hole termination for secure PCB attachment.
• Gold-plated contacts ensure reliable conductivity within the Datamate J-Tek ecosystem.

Applications

• High-speed data interface connections requiring controlled impedance.
• RF module interconnections in compact electronic assemblies.
• Board-to-board or cable-to-board links in telecommunications equipment.

Procurement Notes

Verify that the specific application environment accommodates the 6 GHz frequency limit and 50 Ohm impedance requirements. Confirm mechanical compatibility with mating female receptacles from the same Datamate J-Tek series. Ensure soldering processes align with the thermal specifications of the PPS insulation material to prevent damage during assembly.

Selection Notes

Select this part when high-frequency performance is critical alongside standard power or signal routing needs. The coaxial structure minimizes electromagnetic interference compared to standard pin headers. Consider the vertical profile constraints as it occupies board space above the mounting plane. Validate that the 8-position count matches the system's channel requirements precisely.

Part Context

This component belongs to the Datamate J-Tek family, known for its robust locking mechanism and mixed-signal capabilities. It serves as a male header counterpart to female sockets within the same series. The model specifically addresses applications needing coaxial connectivity in a small form factor, bridging RF signals with standard board interfaces.

Replacement Considerations

Direct substitutes must match the 8-position coaxial configuration, 4.00mm pitch, and vertical through-hole style. Verify that any alternative maintains the 50 Ohm impedance and 6 GHz frequency rating. Cross-referencing with other Harwin M80 variants requires checking contact geometry and housing dimensions for mechanical fit.
