The DCB Series of metalized polypropylene film capacitors from Illinois Capacitor offers capacitance.That property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors.Its value is expressed as the ratio of a quantity of electricity to a potential difference.A capacitance value is always positive.values from 7.5 to 55µFUnit of capacitance.The basic unit of a measure of a capacitor.A capacitor charged to 1 volt with a charge of 1 coulombA coulomb is the unit of electric charge.It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second.It can also be defined in terms of capacitance and voltage,where one coulomb is defined as one farad of capacitance times one volt of electric potential difference.would have a capacitance of 1 farad.1 microF=.000001 Farads.at voltages up to 1100VDC 1375VDC surgeA transient variation in the current and/or potential at a point in the circuit..Four leads are provided for excellent on-board stability and performance.The DCB Series includes 19 values,with voltage ratings of 700 to 1100WVDC.Operating temperature ranges from-40°C to+85°C for extended life in high-performance applications.Highly reliable,the expected failure rate is only 300 per-billion component hours.Other features include very low self inductance and a rectangular,flame-retardant plastic case.DCB capacitors are an excellent choice for power inverters,DC Link,AC/DC motor controls and welding equipment.With small size and a space efficient package design,they will help to reduce board size and case requirements.All values in the DCB Series are radial leaded,withcase sizes ranging from 42.5×33.5×22 to 57.5x50x30.The parts are also fully RoHS compliant.Like other IC capacitors,each DCB Series capacitor is 100%burn-in tested.
