Overview
The datasheet details the specifications and performance characteristics of the ATC 700 B Series NPO Porcelain and Ceramic Multilayer Capacitors, which are ideally suited for RF and microwave applications, offering reliable performance and high durability.
Key Features
The capacitors in this series boast low Equivalent Series Resistance (ESR/ESL), zero Temperature Coefficient of Capacitance (TCC), and high self-resonance, making them suitable for minimizing drift in RF power applications. The porcelain and ceramic construction provides a robust, hermetic package.
Quality Factor (Q)
This line of capacitors has a high quality factor, with a Q of greater than 10,000 from 0.1 pF to 200 pF, and greater than 2000 in the range of 220 pF to 1000 pF – measured in MHz. For capacitances from 1100 pF to 5100 pF, the Q is greater than 2000, measured in kHz.
Capacitance and Temperature Coefficient
The capacitors provide a stable capacitance across a wide temperature range (-55°C to +125°C), with a TCC of ±0.30 PPM/°C.
Insulation Resistance (IR)
They exhibit high insulation resistance, with a minimum of 10^5 Megohms at +25°C and +125°C across various voltage ratings.
Working and Dielectric Withstanding Voltage
The capacitors support a range of Working Voltage (WVDC) and Dielectric Withstanding Voltage (DWV), where the DWV ranges from 120% to 250% of the WVDC, depending on the rated voltage, tested over a period of 5 seconds.
Environmental Resistance
The series is designed to meet or exceed standards set by EIA-198, MIL-PRF-55881, and MIL-PRF-123, showing resilience in various environmental tests such as thermal shock, moisture resistance, low voltage humidity, and life test, demonstrating minimal aging effects and withstanding harsh operating temperatures ranging from -55°C to +175°C (capacitance dependent).
Capacitance Values and Applications
Capacitance values range from 0.1 pF to 5100 pF, making the capacitors suitable for functional applications in bypassing, coupling, tuning, DC blocking, and circuit applications like filters, oscillators, timing circuits, and RF power amplifiers.
Termination and Mechanical Specifications
Various surface mount and leaded termination styles are available, offering strong terminal strength that can withstand significant pulling force, which is tested to the MIL-STD-202 standard.
Contact Information and Certification
The datasheet also provides contact details for ATC’s regional offices in North America, Europe, and Asia, highlighting the company’s ISO 9001 registration and indicating its commitment to quality management practices.
