Frequently Asked Questions

1. What configurations are available for the 2.54mm male header?

This series is available in Single Row (1×2 to 1×40 pins), Dual Row (2×2 to 2×40 pins), and Triple Row configurations, with both Straight (180°, vertical) and Right Angle (90°, horizontal) mounting options. This provides broad flexibility for PCB stacking, motherboard-to-daughterboard connections, and space-constrained layouts.

2. What is the electrical rating?

Rated for 3.0A AC/DC at 250V AC/DC, with a maximum contact resistance of 20mΩ and insulation resistance of 1000MΩ minimum. These specifications ensure stable signal transmission and reliable power delivery in both industrial control and consumer electronic applications.

3. What insulator materials are available?

Four options: PBT (cost-effective for standard applications), PA6T (higher heat deflection for SMT processes), PA9T (improved moisture resistance and mechanical strength), and LCP (highest temperature rating for lead-free reflow soldering). All are UL 94V-0 rated for flame retardancy.

4. What is the operating temperature range?

The connector operates from -40°C to +150°C depending on the selected insulator material. LCP offers the highest thermal performance for demanding industrial or automotive environments, while PBT provides a cost-effective solution for standard indoor applications.

5. What contact materials and plating options are offered?

Contacts are made of high-conductivity Brass or Copper Alloy. Plating options include Gold Flash, Tin Plated, and Selective Gold, allowing you to balance cost and performance based on your application’s mating cycle requirements and environmental conditions.

6. What mounting technologies are supported?

Both Through-Hole (THT) for wave soldering and Surface Mount (SMT) for reflow soldering are supported. The high-temperature insulator options (PA6T, PA9T, LCP) withstand the peak temperatures required for lead-free reflow profiles.

7. What pin lengths and packaging options are available?

Standard pin lengths are e.g. 6.0mm tail / 3.0mm mating, with full customization available for specific stack heights. Packaging options include Tube, Box, and Tape & Reel for automated pick-and-place assembly.

8. What are the primary application areas?

Key applications include industrial control and automation (PLCs, sensors), mainboard prototyping (Arduino, Raspberry Pi ecosystems), telecommunications equipment (switches, routers), smart home and IoT modules, and Battery Management Systems (BMS) in power supplies.
