USB USB-A: for terminating of cables,USB-B: development boards,micro-USB: consumer devices Allows for data communication and charging,mini-USB is slowly getting phased out USB-A- TE’s 1734366 seriesUSB-B- FCI’s 61729 seriesMicro-USB- FCI’s 101035 series

Headers To connect boards and shields Available in male and female versions,0.1” pitch is most popular Male headers- TE’s 4-1037 series Female headers- TE’s 5-53423 series

Screw terminals To hold wires temporarily Holds wires via adjustment of screw,but wires can be undone easily On Shore Technology’s OSTTH series

IC Sockets DIP- ICs, resistor networks, LEDs PLCC- ICs such as flash memory Can be soldered directly onto aPCB for easy replacement of ICs DIP Socket- TE Connectivity’s 1-2199 series

BNC For video, lab and radio equipment Handles up to 4 GHz, with bayonet connection whileTNC/N uses threaded connection TE Connectivity’s 5-16345 series

SMA Coaxial connection in compact spaces Handles up to 18 GHz, but needs torque wrench to connect TE Connectivity’s 10525 series

Backplane Computer systems Provides a “backbone” to connect manydifferent circuit boards in parallel Molex’s 850 series

D-Sub RS-232 communication, video DB-25 with 25 sockets andDE-9 with 9 sockets most popular TE Connectivity’s 17343 series

FFC / FPC Alternative to rigid connectorsand PCBs Provides flexibility, but costlier than rigid PCBs FCI’s SFW series

Modular / Ethernet Initially for telephone, now for Ethernet 8P8C is most common type Molex’s 48025 series
