Additional Details:

Sprague-Goodman UHP series trimmer capacitors typically use a dielectric material such as air, sapphire, or PTFE (Teflon). The capacitance is adjusted by changing the distance between the rotor and stator plates. The UHP408 series is known for its robust construction and ability to withstand harsh environmental conditions. The specific capacitance range, voltage rating, and operating temperature range will vary depending on the specific model within the UHP408 series. Consult the manufacturer's datasheet for detailed specifications. These capacitors are essential components for achieving precise tuning and stable performance in high-frequency circuits. They are also used in specialized applications where high reliability and stability are critical.
