SMD pin headers are designed for use in SMD applications where the components are directly mounted onto the surface of the circuit board. 

SMD pin headers have many sizes and configurations and come in straight and right-angle versions. 

They are used in consumer electronics, computer peripherals, and other compact electronic devices.  

  • Box Pin Headers

Box headers, or shrouded pin headers, are used for a secure connection where vibration or movement is a concern. They feature a plastic shroud to cover the pins, protecting against damage or short circuits.  

Where compactness and reliability are paramount, box headers find frequent uses, particularly in high-density applications.  

  • IDC Pin Headers

Insulation Displacement Connector (IDC) pin headers connect to ribbon or flat cables. They use a particular tool to insert the wires into the connector, which cuts through the insulation and securely links with the conductor. 

IDC headers see widespread use in electronic devices such as printers, disk drives, and other related applications. 

  • Through-Hole Pin Headers

Through-hole pin headers are traditional for electronics manufacturing. They have pins that go through the circuit board and are soldered on the other side to make a secure connection. 

Through-hole pin headers are robust and reliable. It makes them ideal for industrial and automotive applications.

  • Dual Row Pin Headers

Dual-row pin headers are like straight-pin headers but have two rows of pins instead of one. 

They are frequently used in applications requiring multiple connections between circuit boards.

  • Pogo Pin Headers

Pogo pin headers use spring-loaded pins to establish a reliable connection. They find frequent applications in test and measurement contexts involving periodic connection and disconnection. 

  • Coaxial Pin Headers

They use a coaxial cable to make a secure connection, providing reliable transmission of signals. 

Coaxial pin headers are designed for high-frequency applications such as antennas, RFID readers, and other wireless communication devices. 

  • FFC/FPC Pin Headers

FFC/FPC headers use a special connector that clamps onto the cable to make a secure connection. 

Their applications include LCDs, touch screens, other consumer electronics, etc.
