Single-phase rectifier bridge: four pins, including two power inputs (L, N), two DC outputs (+,-)

How to connect a flat bridge rectifier bridge and how to measure the quality of the rectifier bridge? From the pin display in the figure below, we can clearly see that one of the four pins of the flat bridge KBU810 has a longer one. In the flat bridge rectification bridge line, we need to use this "special" pin as a reference, find out the positive and negative poles of the rectifier bridge and then connect them correctly.

Like the KBU810, other flat bridge rectifier models also have the characteristic of unequal length of four pins, which is the most critical part to distinguish the positive and negative poles of the flat bridge stack. The longest pin represents the positive pole of the product, and there will also be a positive symbol on the product.

Round feet and flat feet are just different package specifications. Others are not different. Due to the different design of the PCB board, the structure of the leads that need to be used will be different.
