When designing electronic circuits, selecting the right connectors is crucial for both performance and reliability. Among various interconnect solutions, the female header stands out for its versatility and robust design. Female headers are commonly used alongside DIP header components in through-hole applications, providing secure mating for integrated circuits and other modules. They are also frequently paired with PCB header connectors to establish stable board-to-board or board-to-wire connections. Available in configurations such as the Single row header, these connectors help save space while maintaining electrical integrity. As essential Electronic components, female headers are widely applied in consumer electronics, industrial controls, and telecommunications equipment, ensuring consistent signal transmission and mechanical durability.
The Female header is engineered with precision to meet stringent industry standards. Key specifications include pitch sizes of 2.54mm, 2.00mm, and 1.27mm, catering to different density requirements. The housing is typically made of high-temperature PA6T or PA9T plastic, which offers excellent resistance to heat and chemicals. Contacts are usually phosphor bronze or brass, often plated with gold or tin to enhance conductivity and prevent oxidation. Current rating generally ranges from 1A to 3A per pin, with a voltage rating up to 250V AC/DC. Operating temperature spans from -40°C to +105°C, making it suitable for various environments. Insulation resistance is typically greater than 1000MΩ, and the dielectric strength can withstand 500V AC for one minute. The connector’s lifespan often exceeds 5,000 mating cycles, ensuring long-term reliability. Below is a detailed table of common Female header models and their parameters:
| Model | Pitch (mm) | Number of Positions | Current Rating (A) | Voltage Rating (V) | Contact Material | Plating | Operating Temperature (°C) |
|---|---|---|---|---|---|---|---|
| FH-254-02 | 2.54 | 2-40 | 3 | 250 | Phosphor Bronze | Gold Flash | -40 to +105 |
| FH-200-01 | 2.00 | 2-30 | 2 | 250 | Brass | Tin | -40 to +105 |
| FH-127-05 | 1.27 | 2-50 | 1 | 250 | Phosphor Bronze | Selective Gold | -40 to +105 |
In addition to the standard specifications, the Female header offers several customization options. Available in vertical and right-angle orientations, it supports both through-hole and surface-mount technology (SMT) for flexible PCB layout. The following list highlights key features and optional enhancements:
