ATC, the industry leader, offers new improved ESR/ESL performance
for the 900 C Series RF Capacitors. This Series exhibits superior vol-
umetric efficiency, providing high levels of capacitance for HF/ RF
power applications. Ceramic construction provides a rugged, hermet-
ic package.
ATC offers an encapsulation option for applications requiring extend-
ed protection against arc-over and corona.
Typical functional applications: Bypass, Coupling and DC Blocking.
Typical circuit applications: HF/RF Power Amplifiers, Switching Power
Supplies, High Frequency SMPS Filters and Medical Equipment.
*For leaded styles only.

ATC accepts orders for our parts using designations
with
or
without
the
“ATC” prefix. Both methods of defining the part number are equivalent, i.e.,
part numbers referenced with the “ATC” prefix are interchangeable to parts
referenced without the “ATC” prefix. Customers are free to use either in
specifying or procuring parts from American Technical Ceramics.
For additional information and catalogs contact your ATC
representative or call direct at (631) 622-4700.
Consult factory for additional performance data.
