Overview
The ATC 700 A Series is a line of NPO Porcelain and Ceramic Multilayer Capacitors specifically designed for RF/Microwave applications. They are constructed to provide low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), along with a Zero Temperature Coefficient of Capacitance (TCC), ensuring stable performance across varying operating conditions.
Key Features
The capacitors offer a wide capacitance range from 0.1 pF to 1000 pF and an extended working voltage (WVDC) up to 250 VDC. The series demonstrates a superior Quality Factor (Q) with values greater than 10,000 for the 0.1 pF to 100 pF range and greater than 2000 for the 110 pF to 1000 pF range measured at MegaHertz (MHz) frequencies.
Electrical Specifications
These capacitors have a rugged, hermetic construction, ensuring durability and reliable performance, backed by compliance with QPL, EIA-198, MIL-PRF-55681, and MIL-PRF-123 standards. Their insulation resistance spans from 10^5 to 10^6 Megohms at 25°C, and they have reliable retrace characteristics with less than 0.02% or 0.02 pF variance. The capacitors also exhibit no aging effects and piezoelectric effects and have a nominal capacitance drift of 0.02% or 0.02 pF.
Mechanical Specifications
With various surface mount termination styles available, these capacitors are adaptable to different circuit applications, such as filters, oscillators, and timing circuits. The terminal strength meets industry standards, able to withstand a pull of 5 lbs minimum to 10 lbs typically for 5 seconds perpendicular to the termination surface of the capacitor.
Environmental and Mechanical Resilience
The series withstands significant environmental stress, including thermal shock per MIL-STD-202 Method 107, moisture resistance per MIL-STD-202 Method 106, and low voltage humidity exposure. The operating temperature range spans from -55°C to +125°C without requiring a derating of the working voltage.
Usability for Engineers
The 700 A Series is positioned as the engineer’s choice, implying its popularity and acceptance among technical professionals. Tailored for crucial applications like bypassing, coupling, tuning, and DC blocking, this product series is versatile and dependable for engineering needs.
Quality and Reliability
The capacitors boast high reliability, meeting stringent life test conditions of 2000 hours at 125°C as per MIL-STD-202 Method 108. They also endure dielectric withstanding voltage tests at 250% of the rated WVDC for 5 seconds.
