Overview
The ATC 800 B Series NPO Ceramic Capacitors are designed for superior performance in high RF power applications. These ultra-low ESR multilayer capacitors are characterized by their rugged reliability, NPO dielectric, and RoHS compliance. Their capacitance range spans from 0.1 pF to 1000 pF, optimized to handle the highest RF power at the highest self-resonant frequencies without piezoelectric effects.
Key Specifications
Quality Factor (Q): Rated at 2000 @ MHz.
Temperature Coefficient of Capacitance (TCC): 0.30 PPM/°C over a temperature range of -55°C to +125°C.
Insulation Resistance (IR): Maintains a minimum of 10⁵ Megohms at +25°C and 10⁴ Megohms at +125°C.
Working Voltage (WVDC): Varied by capacitance values detailed on page 2.
Dielectric Withstanding Voltage (DWV): 250% of rated WVDC for 5 seconds.
Applications and Performance
These capacitors are optimal for VHF, UHF, HDTV broadcast transmitters, wireless communications, public safety radio, avionics, telecom, WiMAX, microwave communication systems, and satellite systems. They excel in circuit applications like high RF power filter networks, combiners, couplers, matching networks, antenna coupling, and DC blocking and bypassing.
Environmental and Durability Standards
The capacitors meet or exceed EIA-198, MIL-PRF-55681, and MIL-PRF-123 requirements, ensuring robustness through various environmental tests. This includes Thermal Shock as per MIL-STD-202, Method 107, and Moisture Resistance via MIL-STD-202, Method 106. Additionally, they are tested for Life Test, enduring 2000 hours at 125°C with 200% WVDC applied.
Product Variants and Ordering
The datasheet includes a detailed table of capacitance values with corresponding rated working voltage (WVDC). Special values, tolerances, and matching options are available upon consultation with the manufacturer. The ATC Part Number Code explains how to interpret the part numbers, ensuring accurate orders, whether designated with or without the “ATC” prefix.
Termination styles offered are RoHS compliant and include solder plate options. Also, the standard packaging is Tape & Reel, with special packaging options available.
