• Mid-K
• Rugged Construction • High Reliability
• Available with Encapsulation Option*
ATC, the industry leader, offers new improved ESR/ESL perform-
ance for the 900 C Series RF Capacitors. This Series exhibits su-
perior volumetric efficiency, providing high levels of capacitance
for HF/ RF power applications. Ceramic construction provides a
rugged, hermetic package.
ATC offers an encapsulation option for applications requiring ex-
tended protection against arc-over and corona.
Typical functional applications: Bypass, Coupling and DC Blocking.
Typical circuit applications: HF/RF Power Amplifiers, High Fre-
quency Switch Mode Power Supplies, and Medical Electronics.
*For leaded styles only.

Termination Code
The above part number refers to a 900 C Series (case size C) 1.0 MFd capacitor,
M tolerance (±20%), 100 WVDC, with W termination (Tin /Lead, Solder Plated over Nickel Barrier), laser marking and Waffle-packaging.
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 (+1-631) 622-4700.
Consult factory for additional performance data.
