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

Category: American Technical Ceramics Corp, Capacitors, Electronics

The datasheet outlines the specifications for the ATC 800 A Series NPO Ceramic High RF Power Ultra-Low ESR Multilayer Capacitors designed for high RF power applications. The capacitors come in a rugged Case A Size with a capacitance range of 0.1 pF to 100 pF. These components are known for their low Equivalent Series Resistance (ESR), reliability, and NPO dielectric, which can handle the highest self-resonant frequencies. Moreover, they are RoHS Compliant and Lead-Free.

Electrical and Mechanical Specifications

The quality factor (Q) of these capacitors is 2000 at 1 MHz. They feature a Temperature Coefficient of Capacitance (TCC) between -55°C to +125°C, maintained within a range of 0 +30 PPM/°C. Insulation resistance is greater than or equal to 10⁵ Megohms at +25°C, and 10⁴ Megohms at +125°C, measured at rated Working Voltage Direct Current (WVDC). The capacitors can handle 250% of rated WVDC for 5 seconds (a test voltage of 625 VDC).

The ATC 800 A Series Capacitors are designed to have no aging effects or piezoelectric effects, which implies no variation in capacitance with voltage or pressure. Capacitance drift is defined as the lesser of ±(0.02% or 0.02 pF).

Environmental Tests and Reliability

These capacitors have been designed and manufactured to not just meet, but exceed the standards of EIA-198, MIL-PRF-55681, and MIL-PRF-123. They perform reliably within the operating temperature range of -55°C to +125°C without any derating of working voltage required. The capacitors also withstand a slew of environmental tests including thermal shock as per MIL-STD-202, Method 107, Condition A and moisture resistance according to MIL-STD-202, Method 106.

In terms of durability, the termination style is RoHS Compliant with a solder plate, and terminates designed for the chips can endure a pull of 5 lbs. minimum and 10 lbs. typically for 5 seconds. Finally, the life test adheres to MIL-STD-202, Method 108, for 2000 hours at 125°C with 200% WVDC applied.

Applications

The ATC 800 A Series Capacitors cater to high RF Power applications in fields ranging from UHF and microwave communications systems to wireless communications, public safety radio, telecommunications, WiMAX, and satellite systems. Their typical circuit applications are in high RF power filters, combiners, couplers, matching networks, output and antenna coupling, as well as DC blocking and bypassing.
