ATC 100 A Series
Porcelain Superchip®
Multilayer Capacitors
• Case A Size • Capacitance Range
(.055" x .055") 0.1 pF to 100 pF
• High Q • Ultra-Stable Performance
• Low ESR/ESL • High Self-Resonance
• Low Noise • Established Reliability (Q PL)
ATC, the industry leader, offers new improved ESR/ESL performance
for the 100 A Series RF/Microwave Capacitors. This is ATC's most
versatile high Q, high self resonant multilayer capacitor. High density
porcelain construction provides a rugged, her metic package.
Typical functional applications: Bypass, Coupling, Tuning, Feedback,
Impedance Matching and DC Blocking.
Typical circuit applications: Microwave/RF/IF Amplifiers, Mixers,
Oscillators, Lo w Noise Amplifiers, Filter Networks, Timing Circuits and
Delay Lines.
