Category: American Technical Ceramics Corp, Capacitors, Electronics

Overview of ATC 800 A Series Ceramic Capacitors

The ATC 800 A Series NPO Ceramic High RF Power Ultra-Low ESR Multilayer Capacitors are designed for high-frequency radio applications, from UHF to microwave frequencies. These capacitors feature the lowest Equivalent Series Resistance (ESR) in their class due to a combination of conductive metal electrode systems, optimized case geometries, and proprietary dielectrics.

Key Specifications

With a capacitance range from 0.1 pF to 100 pF, these capacitors also offer a Quality Factor (Q) of 2000 at 1 MHz and a Temperature Coefficient of Capacitance (TCC) of 0 ±30 PPM/°C across a wide operating temperature range of -55°C to +125°C. The series guarantees an Insulation Resistance (IR) of 10^5 Megohms minimum at +25°C and 10^4 Megohms minimum at +125°C.

Performance and Reliability

The capacitors maintain reliable performance under high power, withstanding typical environmental tests and exhibiting no aging or piezoelectric effects. They encounter no capacitance drift beyond ±(0.02% or 0.02 pF) after life tests. Dielectric Withstanding Voltage (DWV) for Case A is 250% of rated WVDC for 5 seconds. They also display robustness in mechanical configurations, handling termination pull strength of 5 lbs. minimum.

Applications

Suitable for high RF power applications, such as wireless communications, the ATC 800 A Series capacitors are versatile in UHF and microwave communication systems, public safety radio, telecom, WiMAX, and satellite systems. They can be employed in high RF power filter networks, combiners, couplers, matching networks, antenna coupling, and for DC blocking and bypassing.

Standards and Packaging

The product series complies with stringent quality standards like EIA-198, MIL-PRF-55681, and MIL-PRF-123. The capacitors are also RoHS Compliant / Lead-Free and available in multiple packaging options, including tape and reel. Special values, tolerances, and matching are available upon request.

Part Numbering and Ordering

ATC’s part numbering system is detailed for easy reference and ordering. For instance, part number ATC800 10 250 X refers to a 10 pF capacitor, with a ±5% tolerance, at 150 WVDC, and with RoHS-compliant tin plating. The capacitors can be ordered with or without the “ATC” prefix in the part number.
