Summary of the ATC 800 € Series Ceramic Capacitors Datasheet

ATC 800 € Series Ceramic Capacitors are specifically designed for high RF power applications, and they perform reliably and consistently across such use-cases. These capacitors offer a capacitance range from 2.2 pF to 3000 pF within a ‘Case C Size’ form factor, which measures 0.250 inches x 0.250 inches. Notable for their high Q, ultra-stable performance, these capacitors feature low Equivalent Series Resistance (ESR) and are compliant with the Restriction of Hazardous Substances (RoHS) directives, ensuring they are lead-free and environmentally conscious.

With an impressive Quality Factor (Q) greater than 5,000 for capacitance values up to 3000 pF, these capacitors ensure minimal energy loss at their resonant frequency, thereby optimizing performance for RF applications. The series operates effectively within a Temperature Coefficient of Capacitance (TCC) of 0 ±30 PPM/°C across a wide temperature range, from -55°C to +125°C, providing a stable response to temperature variations.

The capacitors also demonstrate exceptional insulation resistance – a minimum of 10^5 Megohms at +25°C and 10^4 Megohms at +125°C at rated working voltage direct current (WVDC). Additionally, their dielectric withstanding voltage (DWV) ranges from 250% of WVDC for units rated up to 500 volts DC, down to 120% of WVDC for those rated above 1250 volts DC, all tested over 5 seconds increments.

Functional Applications: The ATC 800 € Series capacitors are adept in various applications, including HF/RF Power Amplifiers, Transmitters, Antenna Tuning, and medical equipment such as MRI coils. They tend to be used for Bypass, Coupling, Tuning, Impedance Matching, and DC Blocking.

From an environmental and durability perspective, the capacitors meet and exceed the requirements prescribed by EIA-198, MIL-PRF-55681, and MIL-PRF-123. They withstand thermal shock, don’t undergo aging effects, resist piezoelectric effects, and operate reliably in moisture-prone conditions. Capacitance drift remains within an upper limit of ±(0.02% or 0.02 pF), ensuring capacitance stability.

The series undergo rigorous testing, ranging from MIL-STD-202 methods for low voltage humidity tests to terminal strength, upholding stringent standards for military and industrial use. The capacitors are built to handle a life test of 2000 hours at 125°C with the applied voltage. They also offer various termination styles, detailed on page 3 of the datasheet (beyond the provided content).

The datasheet also specifies contact details for American Technical Ceramics (ATC) across North America, Europe, and Asia, highlighting their global availability and support. ATC is advertised as an ISO 9001 registered company.
