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 are offered by American Technical Ceramics, an industry leader recognized for its products with reliable performance in RF/Microwave applications. These capacitors, available in Case A Size and offering a capacitance range of 0.1 pF to 1000 pF, feature Low ESR/ESL, Zero TCC (Temperature Coefficient of Capacitance), and High Self-Resonance, making them ideal for demanding electrical and mechanical specifications.

Quality Factor and Temperature Coefficient

The Quality Factor (Q) of these capacitors is greater than 10,000 for capacitances ranging from 0.1 pF up to 100 pF and remains high at greater than 2000 for capacitance values from 110 pF to 1000 pF, both measured in MHz. The TCC is remarkably stable at 0 to +30 PPM/C throughout a wide temperature range of -55°C to +125°C, ensuring minimal drift across various conditions.

Insulation Resistance and Working Voltage

Insulation Resistance (IR) numbers are impressive, with a minimum of 10^6 Megohms at +25°C and 10^5 Megohms at +125°C for capacitances from 0.1 pF to 470 pF. For values between 510 pF and 1000 pF, the IR minimum is 10^5 Megohms at +25°C and 10^4 Megohms at +125°C. The Working Voltage (WVDC) of these capacitors varies, and specifics can be found in the Capacitance Values Table on page 2 of the datasheet.

Electrical Characteristics and Environmental Tests

The series can withstand 250% of rated WVDC for 5 seconds (DWV) and shows negligible retrace and aging effects. Environmental robustness is further guaranteed, with the capacitors meeting the requirements of EIA-198, MIL-PRF-55681, and MIL-PRF-123 standards. Additional environmental test compliance includes MIL-STD-202 methodologies for resistance against thermal shock, moisture, low voltage humidity, and life (operating for 2000 hours at 125°C).

Physical Properties and Applications

These capacitors are manufactured to be rugged and hermetic. They resist piezoelectric effects and feature thermal stability over a broad range of operating temperatures, from -55°C up to +125°C without derating the working voltage. Various surface mount termination styles are available, with the chips and pellets terminations being able to withstand a 200% WVDC applied pull of 5lbs minimum, 10lbs typical; this is tested by a pull lasting 5 seconds in a direction perpendicular to the termination surface.

Typical Uses

ATC 700 A Series Capacitors are utilized in a wide array of circuit applications such as Bypass, Coupling, Tuning, DC Blocking, Filters, Oscillators, and Timing circuits. Their robustness and precise electrical characteristics ensure consistent performance in these critical functions.
