It is therefore necessary to use chip resistors with applied anti-sulfurated measures in environments with a high sulfur content. Anti-sulfurated measures include the adoption of a structure that does not easily allow the penetration of sulfur into the internal electrode section and the use of a sulfuration-resistant metal for electrodes.
Biaxially-orientated polypropylene (BOPP) films are commonly used as dielectric materials in film capacitors because of their outstanding breakdown resistance, excellent charge–discharge efficiency, and largescale processability [1].But when temperature above 105 ℃, a significant increase in leakage current will occur in the amorphous region, reducing …
