Category: American Technical Ceramics Corp, Capacitors, Electronics

Overview of ATC 800 B Series Ceramic Capacitors

The ATC 800 B Series NPO Ceramic, High RF Power Ultra-Low ESR Multilayer Capacitors are designed to perform in high-demand RF power applications requiring consistent reliability. The capacitors range in capacitance from 0.1 pF to 1000 pF and are recognized for their low equivalent series resistance (ESR) and robust thermal performance, thanks to their highly conductive metal electrode systems and specialized case geometries.

Key Specifications

The Quality Factor (Q) of these capacitors is high, achieving 2000 at 1 MHz. They also feature a stable Temperature Coefficient of Capacitance (TCC) at 0.30 PPM/°C across a wide temperature range (-55°C to +125°C), ensuring performance consistency under diverse environmental conditions. The Insulation Resistance (IR) is excellent, maintaining a minimum of 10^5 Megohms at +25°C and 10^4 Megohms at +125°C.

Applications and Compliance

Typical applications for the 800 B Series include communication systems like VHF, UHF, HDTV broadcasting, and more, reflecting their adaptability in various RF power contexts. Circuit applications include high RF power filters, matching networks, and DC blocking and bypassing, among others.

These capacitors are RoHS Compliant, lead-free, and undergo rigorous environmental tests to exceed the standards of EIA-198, MIL-PRF-55681, and MIL-PRF-123. Their durability is further evidenced by Thermal Shock and Moisture Resistance testing, along with a Life Test that subjects them to 200% rated working voltage for 2000 hours at 125°C.

Product Options and Availability

The datasheet lists various rated capacitances and tolerated voltages, along with specific codes for each product variant. Available packaging options include Tape & Reel, with other special packaging available upon request.

In terms of performance, the capacitors showcase minimal capacitance drift and absence of piezoelectric effects, which prevents capacitance variation with voltage or pressure. The operating temperature range does not require derating, allowing the capacitors to function at full capability between -55°C and +125°C.
