Category: American Technical Ceramics Corp, Capacitors, Electronics

Overview of ATC 700 B Series Capacitors

The ATC 700 B Series encompasses a range of high-performance NPO (Negative-Positive-Zero) porcelain and ceramic multilayer capacitors. These are especially designed for RF and microwave applications, boasting low Equivalent Series Resistance (ESR), low Equivalent Series Inductance (ESL), and Temperature Coefficient of Capacitance (TCC) standing at zero. Their self-resonance properties are notably high, and they offer extended working voltage up to 1500 VDC.

Key Specifications and Qualities

The capacitors demonstrate an exceptional Quality Factor (Q), which exceeds 10,000 for capacitances from 0.1 pF to 200 pF at MHz frequencies, and remains above 2000 from 220 pF to 5100 pF at KHz frequencies. This series is built robustly, reflected in its rugged porcelain and ceramic construction, and these capacitors are considered hermetic, assuring resilience and reliability. They have surpassed various environmental tests and are compliant with stringent standards like EIA-198, MIL-PRF-55681, and MIL-PRF-123.

Electrical Characteristics and Reliability

Insulation Resistance (IR) is impressive, with a minimum of 10^6 Megohms at +25°C across most capacitance values. The capacitors maintain a stable capacitance with No Piezoelectric Effects and exhibit no Aging Effects or Retrace over time. ATC 700 B Series capacitors can endure thermal shocks, moisture resistance tests, and low voltage humidity tests without faltering in performance.

Operating Conditions and Applications

Operational temperature ranges span from -55°C to +175°C for capacitors with capacitances up to 200 pF, and from -55°C to +125°C for higher capacitance models. These capacitors are optimized for uses such as bypass, coupling, tuning, DC blocking, filters, oscillators, timing circuits, and RF power amplifiers.

Product Variations and Codification

The capacitance values table details extensive options, with emphasis placed on models with DIELECTRIC (porcelain vs. ceramic) and Extended WVDC capabilities. The part number coding system enables customization of capacitance, tolerance, packaging, and more, providing users with tailored solutions for specific requirements.

Termination Styles and Mechanical Configurations

Multiple termination styles cater to various mounting needs and ensure strong terminal strength. Mechanical configurations pertinent to chip and pellet models are addressed on page 3 of the full datasheet, indicative of the diverse scope of applications and design considerations.

For custom requirements such as special values, tolerances, higher WVDC, and matching, consumers are encouraged to consult the factory. The datasheet provides ordering instructions and assures interchangeability with parts designated with or without the “ATC” prefix.
