The 27273-3R5 is a miniature Giga-Trim trimmer capacitor used for precise adjustments in high-frequency applications. It features an adjustable capacitance range from 0.6 to 4.5 pF over more than eight turns of adjustment. This component offers a high Q factor of over 3000 at 250 MHz, a working voltage of 500 VDC, and operates reliably across a temperature range of -65°C to +125°C. Its robust design with a sapphire dielectric makes it ideal for applications such as RF amplifier tuning, impedance matching, and interstage coupling.
