Chip capacitors or surface mount capacitors do not have leads. They are used in aerospace, automotive, general-purpose, high voltage, high frequency, microwave, and telecommunication applications. Most chip capacitors are packed in tape reel assemblies, carbon-powder trays or rails, and shipping tubes or stick magazines. Bulk pack parts are distributed as individual products. Some chip capacitors or surface mount capacitors are polarized or self-healing. Others meet military standards or do not exhibit capacitance variation with voltage or pressure. Capacitance measures the ability to store energy, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. Chip capacitors that comply with Restriction of Hazardous Substances (RoHS) are also available.
