Sprague-Goodman Electronics, Inc. Trimmers, Variable Capacitors GWN8R000

The GWN8R000 is a variable capacitor trimmer designed for applications requiring precise tuning and stability. It features a capacitance range of 0.8 to 8 pF and operates at a rated voltage of 500 VDC, with a dielectric withstanding voltage of 1000 VDC. The capacitor is constructed with a sapphire dielectric, providing very high Q at UHF and microwave frequencies, making it suitable for stable oscillators, frequency multipliers, and filters. This model is designed to meet MIL-C-14409D specifications and offers precision adjustment with a thread count of 169 threads per inch. It maintains excellent stability over a wide temperature range of -55°C to +125°C. The GWN8R000 has a contact resistance of 0.01 Ohms and an insulation resistance of at least 10^6 Megohms at 500 VDC. It is available in various mounting styles, including leadless options, to accommodate different RF structures.
