About TE Connectivity

TE Connectivity (TE) is a global leader in connectors and sensors, serving industries from automotive to aerospace for over 75 years. Their reputation for engineering excellence and rigorous testing standards ensures components meet critical performance and safety requirements in the most challenging applications.

TE’s MTA-100 series is renowned for cost-effective reliability in wire-to-board interconnects. With a commitment to innovation and sustainable manufacturing, TE components like this header are trusted worldwide for consistent quality and longevity, reducing system failure risks.

About Rectangular Headers

Rectangular headers are fundamental interconnects providing secure electrical pathways between printed circuit boards (PCBs) and cables or wires. Their standardized pitch and configurations enable modular, serviceable designs across electronics. Choosing high-quality headers is vital for signal integrity, mechanical stability, and long-term system reliability.

Headers like the MTA-100 series excel in space-constrained applications due to their compact footprint. Features like shrouding (as seen in this model) prevent pin damage and misalignment during mating. Proper selection based on pitch, current rating, and environmental needs ensures optimal performance in power delivery, data transfer, and control signal applications.

Packaging

This product is supplied in Bulk Packaging for efficient handling and integration into production lines.

Frequently Asked Questions

Q: What wire gauge is compatible with this header?
A: The current rating varies by wire gauge. Consult the TE Connectivity datasheet (hosted on PCXCo.com) for detailed ampacity charts based on wire size and temperature.

Q: Is this header RoHS compliant?
A: Yes, this TE Connectivity MTA-100 header complies with RoHS (Restriction of Hazardous Substances) directives.

Q: Can I mate this with existing MTA-100 housings?
A: Absolutely. This header is designed for seamless friction-lock mating with standard TE Connectivity MTA-100 receptacle housings.

Q: What’s the benefit of a right-angle vs. vertical header?
A: Right-angle headers (like this model) route cables parallel to the PCB, saving vertical space—ideal for low-profile enclosures. Vertical headers connect perpendicularly.

Q: How does the shrouding improve reliability?
A: The 1-wall shroud protects pins from bending, guides mating connectors for proper alignment, and provides polarization to prevent incorrect insertion.

Q: Why choose TE Connectivity connectors?
A: TE Connectivity is synonymous with reliability, offering rigorously tested components with global certifications. Their extensive R&D ensures products meet evolving industry demands for performance and durability.
