ATC 800 A Series NPO Ceramic, High RF Power Ultra-Low ESR Multilayer Capacitors

Category: American Technical Ceramics Corp, Capacitors, Electronics

The ATC 800 A Series NPO Ceramic Capacitors are designed for high RF power applications, combining highly conductive metal electrode systems, optimized case geometries, and proprietary dielectrics to achieve ultra-low Equivalent Series Resistance (ESR). These capacitors offer the lowest ESR values while providing the highest self-resonant frequency and Case A size optimized for high RF power. They are RoHS Compliant and Lead-Free, signifying adherence to current environmental and safety standards.

Key Electrical and Mechanical Specifications

Quality Factor (Q): Capacitors display a quality factor of 2000 @ 1 MHz, indicating low energy losses in reactive components.

Temperature Coefficient of Capacitance (TCC): Showcasing a TCC of 0 to +30 PPM/°C, these capacitors ensure performance consistency from -55°C to +125°C.

Insulation Resistance (IR): They maintain a minimum IR of 10⁵ Megohms at +25°C and 10⁴ Megohms at +125°C at rated working voltage direct current (WVDC).

Working Voltage (WVDC): The working voltage aligns with Capacitance Values Table (located on page 2).

Dielectric Withstanding Voltage (DWV): Each capacitor can withstand 250% of rated WVDC for 5 seconds, translating to 625 VDC for Case A.

Retrace: Less than ±(0.02% or 0.02 pF), whichever is greater, showing minimal deviation and reliable performance.

Environmental and Reliability Standards

Aging Effects: Exhibits no aging effects, ensuring long-term stability.

Piezoelectric Effects: Unaffected by voltage or pressure variation, thus nullifying concerns about capacitance fluctuation due to these factors.

Capacitance Drift: Has minimal capacitance drift, not exceeding ±(0.02% or 0.02 pF).

Thermal Shock and Moisture Resistance: Meets the MIL-STD-202 standards for both thermal shock and moisture resistance, evidencing robustness in diverse environmental conditions.

Operating Temperature Range: These capacitors operate effectively with no working voltage derating from -55°C to +125°C.

Mechanical Endurance and Applications

Terminal Strength: The terminations can withstand a 5-pound minimum and 10-pound typical pull force, asserting durability.

Life Test: Passed life test of 2000 hours at 125°C with 200% WVDC applied, verifying longevity.

Applications: Ideal for use in UHF and microwave communications systems, wireless and public safety radios, telecommunications, WiMAX, satellite systems, and various circuit applications, including RF power filter networks and matching networks.
