RF Chip Capacitors offer rated performance up to 4,000 Vdc.

Press Release Summary:

Utilizing high Q alumina silicate (mica) resin/epoxy construction to avoid cracking and delaminating, Type MCH capacitors feature cataloged capacitance values from 10-220 pF at 4,000 Vdc and up to 1,000 pF at 2,500 Vdc. Chips are available in .380 x .380 in. case, and rugged flexibility and high temperature threshold of chips is compatible with FR4 boards and permits wave soldering. MCHN non-magnetic version is also available.

Original Press Release:

High Voltage SMD Mica Capacitors Offer Better Performance than Porcelain in RF Applications

New Bedford, MA, June 22, 2007 - Cornell Dubilier Electronics (CDE) has expanded its series of multilayer RF chip capacitors. The new 2500 Vdc and 4000 Vdc rated Type MCH uses high Q alumina silicate (mica) /resin/epoxy construction to avoid cracking and delaminating associated with porcelain and NPO ceramics in large SMD sizes. The natural rugged flexibility and high temperature threshold of these chips is compatible with FR4 boards and permits wave soldering. A non-magnetic version, MCHN, is available for applications such as MRI where strong magnetic fields are present. Type MCH and MCHN are designed for use in high RF power designs where stability and low losses are critical. Applications include MRI coils, plasma chambers, baluns, lasers, RF power amplifiers, antennas and transmitters.

Type MCH is available in a 3838 (.380" x .380") (9.9 mm x 9.9mm) case size, surface mountable package. The cataloged capacitance values range from 10 pF to 220 pF at 4000 Vdc and up to 1000 pF at 2500 Vdc. The MCH boasts lower ESR, higher Q and higher current carrying capability than other similar dielectrics including porcelain and NPO ceramics. Pricing begins at under $5 each in OEM quantities. Lead-time is stock to 8 wks from authorized CDE distributors. See the product datasheet, kits and technical data at www.cde.com. For technical inquiries contact
