According to the capacitive components on the electrical function of the selected data, if there are several suitable data available for candidates, it is necessary to calculate from the aspect of cheap quality, to take the most program, and according to the relevant requirements for planning and accounting.
The requirements for the applicable environmental conditions are:
(1) Operating temperature range. In order to plan the heat generation of capacitors or power dissipation of resistors, it is necessary to confirm the upper operating temperature of capacitive components in order to confirm their materials and structure; for liquid impregnated media or electrolytic capacitors with liquid electrolyte, resistors or capacitors with organic resin or lacquer maintenance, attention should also be paid to their properties at the limit of operating temperature, taking into account the entire temperature range of the impregnated liquid, electrolyte, and The influence of the maintenance layer material on the function of the components.
(2) the relative humidity of the operating environment, according to the selected external structure of the component form and external maintenance material.
(3) The air pressure of the operating environment. Mainly on the breakdown of components, discharge function has an impact, such as high-voltage capacitors due to low air pressure to increase the amount of edge, resistors due to low air pressure to increase the width of the groove, etc..
(4) The requirement of bearing mechanical stress, according to which to choose the appropriate strength of the material, the outer layer of maintenance and lead-out methods. If there is no special requirement for environmental conditions, then it will be handled according to the general technical conditions. Capacitor, ceramic capacitor, film capacitor
The planning of resistive capacitor components includes two parts: the main body (capacitor core, resistor body) and the external structure. The former mainly considers the electrical function requirements of the components, while the latter mainly combines the main planning and the environmental conditions required by the components to confirm the external structure. Therefore, the planning starts with the material, scale and structure of the main part, and then the external structure is selected according to the operating conditions.

The planning of the resistive components is based on the required electrical functions. In order to ensure that the components operate reliably for a long time, thermal accounting must be carried out to confirm whether the temperature of various materials (medium and auxiliary materials) exceeds the promised limit temperature and whether the resistor heat generation is lower than the promised dissipation power under the operating conditions of the capacitor. In order to be suitable for industrial planning and mass production, cost and economic efficiency calculations must also be made.
