Cornell Dubilier has announced, effective August 31, 2014 they are discontinuing the following series, 556, 066, 066X, 066R, TC, TCG, 057, M39018/03, & TCX.  R & J Components stocks some of the series and is ready to ship today.  Not only do we have some in stock, our team, of engineers can cross reference the Cornell Series for you. 

MKC/PS Capacitors

Film capacitors are an important component in many of the circuits designed today. Engineers realize that the qualities and cost in using this style of capacitor are essential in producing the best product at the right price. However what happens when the material they would like to use has been discontinued by the manufacturer?  They can scramble around and try to find an alternative or they can contact Standard Radio. We have one of the industries largest selections of film capacitors in stock. Our product knowledge and tremendous inventory has made us a leader in supplying capacitors for over 60 years.

When they were still being made, polycarbonate and polystyrene capacitors were very popular in designs that needed stability and where a capacitor that was small in size was required. Both of these materials are no longer being made by the manufacturers and as a result capacitor manufacturers cannot make product using polycarbonate and polystyrene as the dielectric. Polypropylene and other materials have been offered as replacements but these are not exact replacements. Standard Radio has film capacitors in stock that use polycarbonate and polystyrene as the dielectric in brands such as ASC, Bishop Electronics Corp, CDE, Electronic Concepts, Electrocube, Philips, Sprague and many more of the industries preferred manufacturers.

Some of the qualities that are offered in a capacitor using polycarbonate and polystyrene as their dielectric are:

Excellent capacitance stability

Tight tolerances

High insulation resistance

Low dissipation 

Typical Applications:

Critical Timing Circuits           Feedback Circuits

Fixed Tuning Circuits             Power Supply Filtering

Gyro Circuits                          Integrating Circuits

Coupling & Decoupling          Pulse Forming Networks

Standard Radio has Polycarbonate and polystyrene capacitors in stock in DC voltages that range from 35VDC up to 630VDC. We have stock in both commercial grade and military grade polycarbonate capacitors. We have axial lead styles and radial leads styles both box type and molded in stock. We have included a suggested manufacturer cross reference list for these types of capacitors in an effort to help find alternates to these discontinued styles of capacitors.

Standard Radio has been a leader in supplying capacitors of every style for over 60 years. We offer our customers excellent customer service and provide them with product knowledge that is priceless. Contact us with any of your capacitor requirements and let us show why we are called the “King of Capacitors”.
