Historically, all Ceramic safety capacitors were in a leaded disc form factor. It is common for leaded disc safety capacitors to come in multiple lead style configurations. The most common are: Straight, outside kink, inside kink, and vertical kink (also known as inline kink). Each of the styles is a modification of the lead form and not the actual disc itself. The various lead styles available provide different mounting options. The straight lead style will seat all the way down to the lower portion of the disc. This means that the capacitor will either touch the PCB or the assembler must hold the capacitor above the board while soldering which leads to inconsistent mounting heights. When choosing a kinked lead style, the capacitors can sit on the circuit board at a consistent height without the bottom of the disc touching the PCB. Each kinked lead style, whether outside, inside or vertical provides this benefit.
