ATC 700 A Series NPO Porcelain and Ceramic Multilayer Capacitors

Category: American Technical Ceramics Corp, Capacitors, Electronics

The ATC 700 A Series NPO Porcelain and Ceramic Multilayer Capacitors offer high performance for RF/Microwave applications with a focus on low Equivalent Series Resistance (ESR)/Equivalent Series Inductance (ESL), zero Temperature Coefficient of Capacitance (TCC), and high self-resonance. They are renowned for their low noise and rugged construction, providing high reliability (QPL certified) and an extended operating voltage up to 250 VDC.

Electrical Specifications:

The quality factor (Q) exceeds 10,000 for the capacitance range of 0.1 pF to 100 pF and remains above 2000 for 110 pF to 1000 pF. A notable feature of these capacitors is the zero TCC of 0 to +30 PPM/°C in the temperature range from -55°C to +125°C. Insulation resistance is high, with a minimum of 10^6 Megohms at +25°C and 10^5 Megohms at +125°C for the 0.1 pF to 470 pF range, while it is 10^5 and 10^4 Megohms, respectively, for the 510 pF to 1000 pF range.

Mechanical Specifications:

The capacitors are hermetically sealed in high-density porcelain and ceramic packages. The dielectric withstanding voltage (DWV) is rated at 250% of the working voltage DC (WVDC) for 5 seconds. Capacitors show no aging effects, piezoelectric effects, or capacitance drift beyond ±(0.02% or 0.02 pF), which is impressive for such components. They are also designed to exhibit less than ±(0.02% or 0.02 pF) retrace.

Environmental and Durability Tests:

The ATC 700 A Series Capacitors have been tested to meet and exceed the requirements of EIA-198, MIL-PRF-55681, and MIL-PRF-123. The series has successfully passed rigorous environmental tests such as thermal shock (MIL-STD-202, Method 107, Condition A), moisture resistance (MIL-STD-202, Method 106), low voltage humidity (MIL-STD-202, Method 103, Condition A with 1.5 Volts DC), and life test at 125°C for 2000 hours (MIL-STD-202 Method 108).

Applications and Operating Range:

These capacitors are ideal for applications such as bypass, coupling, tuning, DC blocking, filters, oscillators, and timing circuits. They can operate over a temperature range from -55°C to +125°C without any derating of the working voltage.

Termination Styles:

Various surface mount termination styles are available, and mechanical configurations details can be found on page 3 of the datasheet. The terminations are robust, withstanding a pull of 5 lbs. minimum, and 10 lbs. typical for 5 seconds in the direction perpendicular to the termination surface of the capacitor.

Overall, the ATC 700 A Series is presented as a series of high-quality capacitors ideal for a wide range of demanding electrical applications.
