    A Study of Electrolytic Capacitor Thermal Conductivity

    Since the capacitor is a heat source, generating a certain amount of heat, the capacitor’s power loss is also a boundary condition. Meanwhile, the PCB can be treated as a heatsink in the system, as it has much bigger thermal mass than the capacitor. The impact caused to the final result by this treatment can be ignored.

    Another important performance factor, thermal management, also mitigates hazards of overheated or unevenly heated capacitors. Workplace exposure to material hazards of electrochemical capacitors could also occur. The Occupational Safety and Health Administration (OSHA) regulates permissible exposure limits for some of the possible materials.

    For most aluminum capacitors, component manufacturers can provide terminations, such as J-leads or three-terminal snap-ins, to help prevent incorrect mounting. In soldering, washing, and board-separation, the most problematic issues are temperature and board flexure. For ceramic capacitors, high temperatures and thermal shock can cause cracking.
