Overview of the ATC 700 A Series NPO Multilayer Capacitors

The ATC 700 A Series offers a range of NPO porcelain and ceramic multilayer capacitors designed especially for RF/Microwave applications with features like low Equivalent Series Resistance (ESR), Equivalent Series Inductance (ESL), Zero Temperature Coefficient of Capacitance (TCC), and high self-resonance. These capacitors also exhibit low noise and high-quality factors, with values greater than 10,000 for capacitances ranging from 0.1 pF to 100 pF and greater than 2000 for capacitances from 110 pF to 1000 pF at their respective MHz frequencies.

Key Specifications and Performance Data

Electrical Characteristics: The 700 A Series capacitors come in a capacitance range of 0.1 pF to 1000 pF and support an extended Working Voltage Direct Current (WVDC) of up to 250 VDC. They have an impressive Temperature Coefficient of Capacitance (TCC) ranging from 0 to +30 PPM/°C over a temperature range of -55°C to +125°C, highlighting their stability under temperature fluctuations. The Insulation Resistance (IR) is noted to be at a minimum of 10^6 Megohms at +25°C and rated WVDC across most of the range, ensuring reliability.

Durability and Reliability: These capacitors are designed for rugged use with hermetic packages that demonstrate High Insulation Resistance, Mechanical robustness, and Moisture Resistance. Additionally, they show no aging effects, piezoelectric effects, or capacitance drift, which are important factors for applications that require consistent performance over time and various conditions. The product has an operating temperature range spanning from -55°C to +125°C without derating of working voltage, and experience Thermal Shock tests in compliance with MIL-STD-202 Method 107, Condition A.

Environmental and Life Testing: The 700 A Series withstands various environmental tests such as Low Voltage Humidity and Life Test, sustaining a minimum of 240 hours at an environment of 85° with 85% relative humidity, and passes a Life Test of 2000 hours at 125°C according to MIL-STD-202 Method 108.

Applications: Due to their construction and electrical characteristics, these capacitors are recommended for Bypass, Coupling, Tuning, DC Blocking, Filters, Oscillators, and Timing circuit applications. They are compatible with various surface mount termination styles which are detailed on page 3 of the full datasheet.

Additional Key Data
