GIGAHERTZ TRIMMER CAPACITORS
Description
• Gigahertz trimmers are tiny trimmer capacitors which provide a straight-forward technique for fine
tuning RF and microwave circuits.
• Gigahertz trimmers withstand the rigors of soldering heat, excessive tuning and rough handling.
As a result of the excellent dielectric and insulation properties of the sapphire or ceramic housing,
high breakdown voltage is achieved. Incorporating the self-locking constant torque drive mechanism,
they offer many improvements a fixed length, increased Q, essentially zero tuning noise and reduced
susceptibility to solder flux intrusion during installation.
• Vertical Surface Mount Gigahertz trimmers versions are available, with models 3, 7 and 8, offering
a good mechanical stability on the circuit board. Self resonant frequency of Vertical surface mount
Gigahertz trimmers versions is improving when the width of the terminal is increasing. They are
available on tape and reel with permanent sealing cap which resists intrusion of solder flux and
cleaning agents and allows easy access to the tuning rotor.
• Surface Mount SM series offer a rectangular outline with horizontal tuning axis.
• Non magnetic Gigahertz trimmer version available.
• NEW : Extended range Gigahertz trimmers designed for applications such as RF power amplifiers feature
a 25 to 35% size reduction
