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, High Frequency
Switch Mode Power Supplies, and Medical Electronics.
*For leaded styles only.

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.
