AIR DIELECTRIC TRIMMER CAPACITORS
AIR DIELECTRIC TRIMMER CAPACITORS
Description
• Standard trimmer air capacitors are designed specifically for RF applications, VHF through
microwave, and have become the industry standard of excellence. High Q and temperature stability are a result of proper attention to geometry and choice of optimum materials. The heart of this
trimmer is the one piece self-locking constant torque drive mechanism. This mechanism utilizes
transverse slots to create a spring effect between two threaded sections resulting in substantial contact areas which insure uniform torque, high Q and low dynamic tuning noise.
• Miniature trimmer air capacitors offer an even further size reduction of the standard air capacitors
coupled with finer tuning resolution and ultra high Q, making them ideal for use in microwave circuits.
• Both standard and miniature capacitors are available in vertical mounting configurations which save
board space and allow top tuning. Vertical mount capacitors are available in single dual and low
inductance leads with upright or inverted tuning.
• Where High voltage is a requirement, the AT5300 series air capacitors are an excellent replacement
for comparable range glass capacitors.
TEMEX reserves the right to modify herein specifications and information at any time when necessary to provide optimum performance and cost.
