6 FAQs about [Requirements for on-site acceptance of capacitors]
How to connect battery-mounted capacitors?
Battery-mounted capacitors should be connected by means of flexible cables or by braids. Thin-film and some small passive components can exhibit sensitivity to Electrostatic Discharge (ESD). ESD charge/discharge voltage can exceed tenth of kilo-Volts and the ESD typical charge current can be around 1 to 10A in many cases.
What temperature should a shunt capacitor be classified?
The shunt capacitors shall be classified by standard temperature categories in accordance with SS-EN 60871-1 and TR01-01 as -40/A and -50/A which correspond to to minimum ambient temperatures of -40°C and -50°C, respectively and maximum ambient temperature of +40°C. Capacitors for indoor installations shall normally be classified –25/A.
What causes field application capacitor failure?
According to a survey by the European Passive Components Institute, mounting related induced failures are the number one reason (over 55%) for field application capacitor failure causes. The mounting guide survey was prepared under European Space Agency ESA contract.
Are MLCC capacitors mechanically sensitive?
MLCC capacitors can be mechanically sensitive. This approach results in improved mechanical strength and better electrical parameters and thermal dissipation for assembling mechanically sensitive MLCC capacitors.
What is a capacitor & resistor mounting survey?
The capacitor & resistor mounting survey aims to collect the manufacturer’s recommendations and good tips for capacitor and resistor mounting beyond the industry standards. It does not provide a complete mounting procedure guidelines as part of specific industrial requirement and standards.
What happens if a board mounted with capacitors is dropped?
When handling a board mounted with capacitors, firmly hold the edges of the board with both hands to prevent it from bending or dropping. If a board is dropped, cracks may occur in the capacitors. Do not use dropped boards, as there is a possibility that the quality of the capacitors may be impaired.
