ATC # 001-815 Rev. K 2/09
ATC 900 C Series X7R
Ceramic RF Power
Multilayer Capacitors
• Case C Size • Capacitance Range
(.250" x .250") 0.01 µF to 1 µF
• Low ESR/ESL • 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.
