W-type horizontal, vertical L-type, small size is suitable for PCB soldered directly to the installation. L2 vertical type, suitable for both board for solder mounting, can be applied to the circuit board mounting the connector. In the selection of the solid state relay of small size PCB current use, because of the lead terminals made of highly thermally conductive material, when welded at a temperature less than 250 deg.] C, under conditions of time less than 10S performed, consider the reason as the ambient temperature, if necessary, consider derating use, generally control the use of the load current is within the rated 1/2.

K-type and F-type, suitable for radiators and floor installation of the instrument. High-power SSR (K and F package) installed, it should pay attention to the heat sink contact surfaces should be smooth, and the need to coated thermal grease (Mabel T-50). Mounting torque larger, the smaller the thermal contact resistance. Large current lead, to be equipped with cold pressure welding sheet to reduce the lead contact resistance.
