mm.
Also available with length of (4.5 1) mm.
B43521, solder pins
Pole markings: Plus: +; Minus:
All pin holes must be drilled into the PC-board, since the unconnected pins serve as mountings.
These pins must be soldered to isolated pads or pads with the same potential as the negative
pole (solder pin and 4-pin snap-in terminals).
