The datasheet provides detailed information on the ATC 600F Series Ultra-Low ESR, High Q, NPO RF & Microwave Capacitors, which are noted for having the lowest ESR (Equivalent Series Resistance) in their class and the highest working voltage at 250V. These capacitors come in the standard EIA Size of 0805 and can be optionally laser-marked.
Applications
These capacitors are ideal for various applications, including but not limited to:
- Cellular Base Stations
- Wireless Communications
- Broadband Wireless Services
- Satellite Communications
- WiMAX (802.16)
Circuit applications for the ATC 600F capacitors encompass Filter Networks, High Q Frequency Sources, Matching Networks, and are also used for Tuning, Coupling, Bypass, and DC Blocking purposes.
Electrical and Mechanical Specifications
The capacitors feature a capacitance range from 0.1 to 240 pF, with various tolerance options as indicated by the Cap Value Chart. They operate over a wide temperature range (-55°C to +125°C) without derating and exhibit excellent temperature stability with a Temperature Coefficient of Capacitance (TCC) of 0 ± 30ppm/°C. The capacitors possess high Quality Factor (Q) values of > 2000 MHz and boast an Insulation Resistance of 10^5 MΩ min. at +25°C, and 10^4 MΩ min. at +125°C after life testing.
Environmental and Quality Assurance
Durability and reliability are assured through rigorous environmental specification testing such as life tests at +125°C, thermal shock cycles, and resistance to moisture as defined by MIL-STD-202. Furthermore, the capacitors carry no piezo effects, conform to military specifications MIL-PRF-55681 and MIL-PRF-123, and come from an ISO 9001 registered company, ensuring top quality standards.
Mechanical Design and Construction
Various termination options are available, including Tin Plated over Nickel Barrier as standard, with alternatives such as Tin/Lead Solder Plated over Nickel Barrier or Tin Plated over Non-Magnetic Barrier. The capacitors demonstrate robust terminal strength, verified through testing, and are solderable with solder coverage encompassing 90% of end termination.
Ordering Information
The datasheet outlines the ATC Part Number Code for ordering, which includes series designation, case size, value code, tolerance, termination, packaging, voltage, and optional laser marking. It is mentioned that ATC accepts part number designation with or without the “ATC” prefix.
For more information, customers are encouraged to contact ATC directly or via regional contacts in North America, Europe, and Asia. The datasheet also suggests consulting the factory for prototype reel options and additional performance data.
