The Benefits of SMD Safety Capacitors for the PCB Designer
Table 1: Classification of Class- X Safety Capacitors. Class-Y Capacitor: Class-Y safety capacitors are connected from the line conductors to ground, and they help filter out high-frequency noise, spikes, and transients that can be conducted back onto the power lines. Y capacitors in EMI filters help to suppress common mode EMI, which …
A Quick Guide to Safety Capacitors | doEEEt
Ceramic or Film capacitors, what fit better as X and Y safety capacitors. Some characteristics to consider would be the temperature profile over the application''s life, size constraints, and maybe even cost or ease of assembly. Ceramics can achieve higher capacitance values in a smaller volume, while the film has a self-healing feature ...

safety
$begingroup$ As a general rule of thumb, before sticking your hands in a circuit with potentially charged capacitors, especially power electronics like audio amplifiers and televisions. It is a good idea to short capacitors across a (largish) bleedoff resistor to discharge them. Sometimes there is a bleedoff path already designed for the larger …
