The locking barb on the terminal body snaps into the 0.055\" (1.40mm) hole, providing mechanical retention before soldering — no secondary fastener needed. This is the terminal that turns a plain wire into a board-locked interconnect, common in appliance, HVAC, and power-supply harnesses where vibration or service access could pull a crimp loose. ## Tin Plating for Cost-Effective Solder Joints The contact finish is tin over phosphor bronze base metal. The trade-off is mating cycle life: tin-on-tin interfaces are rated for fewer cycles than gold, so this terminal suits a one-time solder-and-forget installation rather than a field-replaceable connector. For a wire-to-board terminal that gets soldered once, tin is the correct call. ## Wire Range and Insulation Diameter Check The terminal accepts 22-26 AWG stranded or solid wire, with an insulation diameter range of 0.060\" to 0.100\" (1.52mm to 2.54mm). That insulation window is the real fit constraint — a 22 AWG wire with thin-wall insulation (0.060\") seats fine, but a 22 AWG wire with heavy-wall insulation (0.110\"+) will not enter the barrel. Verify the insulation OD on your specified wire before committing the BOM line. ## PCB Hole and Board Lock Detail The specified PCB hole diameter is 0.055\" (1.40mm). The locking barb on the terminal body engages this hole diameter to hold the terminal in place during handling and wave solder. For PCB layout, the hole size and the annular ring around it must match the terminal's barb geometry — the datasheet drawing shows the recommended footprint. The overall terminal length is 0.250\" (6.35mm), which sets the board clearance under the solder tail. No NRND or last-time-buy notice is in effect.","metaTitle":"TE Connectivity 3-640108-1 Mini Amp-In Terminal, 22-26 AWG","metaDescription":"TE Connectivity 3-640108-1 Mini Amp-In through-board locking terminal, 22-26 AWG, tin-plated phosphor bronze.
