ATC 700 B Series Multilayer Capacitors Datasheet

Category: American Technical Ceramics Corp, Capacitors, Electronics

Overview: The ATC 700 B Series NPO (Negative-Positive-Zero) Ceramic and Porcelain Multilayer Capacitors are engineered for optimal performance in RF and microwave applications. These rugged, high-quality capacitors offer a wide capacitance range from 0.1 pF to 5100 pF and are available with an extended working voltage (WVDC) up to 1500 VDC.

Key Features:

The 700 B Series is renowned for its low equivalent series resistance (ESR), zero temperature coefficient of capacitance (TCC), low noise, and high self-resonance. Quality factors exceed 10,000 for capacitances from 0.1 pF to 200 pF at MHz frequencies, and over 2000 from 220 pF to 5100 pF at KHz frequencies. Operating temperature ranges from -55°C to +175°C for certain models, ensuring reliability across various environments.

Performance Specifications:

These capacitors demonstrate excellent insulation resistance, with a minimum of \$10^5$ Megohms at +25°C and +125°C across the capacitance range. The dielectric withstanding voltage (DWV) is set at percentages ranging from 250% to 120% of WVDC, depending on the rating.

Compliance with rigorous environmental and mechanical standards like EIA-198, MIL-PRF-55881, and MIL-PRF-123 is ensured. They are designed to withstand thermal shock as per MIL-STD-202, Method 107, Condition A. Piezoelectric and aging effects are nonexistent, and retrace is kept minimal.

Applications:

Functional uses for the 700 B Series include bypassing, coupling, tuning, and DC blocking. Circuits employing these capacitors typically involve filters, oscillators, timing mechanisms, and RF power amplifiers.

Physical Characteristics:

Terminations are constructed to handle a tensile force from 5 lbs. minimum to 15 lbs. typical. An optional encapsulation is available for additional protection against arcing and corona, particularly in high-voltage scenarios. Surface mount and leaded styles are offered to suit diverse mounting requirements.

Capacitance and Voltage Ratings:

The datasheet lists capacitance values with corresponding standard and extended WVDC ratings. For instance, a 0.1 pF capacitor (code OR1) has a standard WVDC of 500 volts, while a 3.3 pF unit (code 333) can be accommodated in a case size B configuration with extended WVDC.

Part Number Coding:

ATC provides comprehensive coding for ease of identification, which includes case size, capacitance code, tolerance, WVDC, and termination code, also offering laser marking for traceability.

The 700 B Series capacitors are identified either by including or excluding the “ATC” prefix in the part number. Capacitance values highlighted in bold indicate a porcelain dielectric, and other values indicate a ceramic dielectric.

Conclusion:

The ATC 700 B Series capacitors are robust, reliable, and suitable for a wide range of electronic applications, meeting the most stringent industry standards and providing customization options through a variety of ratings and packaging choices.
