Cornell Dubilier is a leading manufacturer of capacitors and related passive components. CDE Cornell Dubilier has been a leader in capacitor technology since 1909, when founder William Dubilier first used a glassy mineral called mica to help form a “condenser” (now called a “capacitor”). Today, CDE has earned a global reputation for manufacturing quality, high-end capacitors. Almost all of the company’s capacitors are used in demanding industrial applications, separating themselves from the competition.

ISO 9001-certified manufacturer, Cornell Dubilier Electronics produces capacitors for a variety of applications, including lighting, motor drives, power supplies, medical equipment, and military and aerospace electronics. Cornell Dubilier Electronics is committed to providing superior quality products including design assistance, custom manufacturing and testing. Before the CDE name goes on a capacitor it is fully tested for compliance to all key electrical characteristics. Depending on the type of capacitor, further thermal, electrical and mechanical testing (pulse, shock and vibration, humidity) may be conducted.

Whether you’re looking for the ultimate in reliability or custom capacitor solutions, you’ll find a Cornell Dubilier capacitor or component the best solution for your project.

Cornell Dubilier (CDE) Product Range

Aluminium Electrolytic Capacitors

CDE offers a wide selection of standard and custom screw terminal, snap-in and board mount capacitors, used extensively in the most critical applications, ranging from defibrillators and medical imaging to radar systems and UPS power backup for large data systems.

Aluminium Electrolytic Capacitor range:

• Axial
• Radial
• Surface Mount
• Prismatic
• Snap-In
• Screw Terminal
• Motor Start
• Photoflash & Strobe

Aluminium Polymer Capacitors

Possessing much lower ESR than other capacitor technologies, CDE’s aluminium polymer capacitors are ideal for board-level power conversion where high ripple current capability is needed. APC offer CDE Aluminium Polymer Capacitors in molded chip, vertical chip (V-Chip) and radial form factors.

Aluminium Polymer Capacitor range:

• Radial
• Vertical Chip
• Molded Chip
• Flat

Film, Paper-Film Capacitors

AC and DC rated film capacitors for industrial, military and medical applications ranging from standard AC motor run types, to custom DC pulse applications. Only the industry’s highest grades of film dielectric are used to ensure the best possible performance. Cornell Dubilier are just a few remaining manufacturers of paper and film combination dielectrics for high-performance power conversion and power supply applications.

Film, Paper-Film Capacitor range:

• Power Film, DC Applications
• Axial
• Radial
• SMT
• X2 and Arc Suppression

Mica Capacitors

As the inventor of the mica capacitor, CDE are the world’s foremost authority and largest manufacturer of mica dielectric capacitors. Cornell’s RF mica capacitors feature superior high Q performance without the undesirable properties associated with ceramic and porcelain capacitors. Cornell Dubilier mica capacitors are extensively used in military, aerospace and medical applications, offering both COTS and Military Grade capacitors with established reliability.

Mica Capacitor range:

• Dipped
• Surface Mount
• Transmitting
• Partial Discharge Coupling

Rechargeable Batteries

CDE’s rechargeable lithium-ion batteries are different in design from other similar-looking batteries. A new encapsulation technology significantly increases storage capacity by completely utilising the space within the cell case. Not only has the energy density per lithium ion been improved, but the failure rate is also superior to older designs.

Rechargeable Battery range:

• Coin Cell

Supercapacitors

Also known as ultracapacitors, double-layer capacitors, or electro-chemical double-layer (EDLCs). CDE has a comprehensive range of capacitance values and voltages. Cornell’s technology is used in a wide variety of applications from battery backup in smart meters to regenerative braking.

Supercapacitor range:

• Supercapacitors Cells
• Hybrid LIC Supercapacitor
• Supercapacitor Modules
• Supercapacitor Coin Cells
