Surface Mount Terminal Blocks

120-M-221-THR 5.00 mm (0.197 in) Spacing   -   2-24 poles Print this page

Description
  • Standoffs underneath the molding prevent bottom of molding from touching the solder paste and allow for a visual inspection of the solder joints and better air flow during the reflow soldering process. Material will handle reflow temperatures well without deforming or melting.

    Type 120-M-221-THR terminal block has been specially designed to allow effective potting of PC boards. The molding design prevents seepage of the potting material into the wire clamping area up to 7.5 mm (0.295 in.) from the board.Removable thermo resistant pick caps are supplied when packed in tape and reel. This allows automated pick & place applications.
  • Through Hole Reflow

Application

WECO's THR designs are adapted for easy integration into your processes. Standoffs provide for;od convective heat circulation for reliable soldering through the elimination of cold spots and also allow for a visual inspection of the solder joints. The main advantage of through-hole terminal blocks is their reliable mechanical strength. This robustness is particularly important for applications exposed to harsh environments or strong vibrations such as mobile equipment, engine or motor compartments.
