Sizzling Hot Applications to 200°C and Gigahertz Frequencies

For SMT RF Mica and Teflon® Capacitors

Liberty, SC (December 2005) — Cornell Dubilier introduces high-power RF capacitors for military/aerospace and commercial radios and transmitters, CATV, automotive and medical RF generators and other applications requiring high-frequency operation into the low gigahertz and high-temperature operation up to 200°C. These robust capacitors are metal clad in silver plated metal cases to enable ultra-low inductance terminations and heat spreading for high power operation. The mica and Teflon® dielectric systems assure very-low ESR to greater than 1 GHz and exceptionally high ripple current capabilities and stability in subminiature sizes. All styles are non-magnetic and are right for use in critical NMR MRI applications.

These Type MCM and MIN capacitors were previously manufactured by SEMCO, Inc. CDE acquired SEMCO and is now manufacturing the 16 variations of both SMD and through-hole, subminiature, metal clad configuration mica and Teflon® capacitors. CDE is a leader in film and mica capacitors, and the MCM and MIN capacitors are now being fully characterized for s-parameters and high frequency Q so that customers can more easily design them into RF applications.

Many ratings are in stock. Voltage ratings are from 300 to 1000 Vdc; capacitance is from 1 to 1500 pF in tight tolerances from ±0.5 pF. Delivery time ranges from stock to 8 to 12 weeks. Volume pricing for a 10 pF, ±0.5 pF unit is 39¢.

Since its founding in 1909, Cornell Dubilier has been dedicated to advancing capacitor technology for new applications. The company combines innovative products with engineering expertise to provide reliable solutions for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, telecom and UPS systems.
