MEIDEN Vacuum Capacitors / VC (Vacuum Capacitors)

UW Type

Low Power RF System Applications : Compact Size·Low Loss·High Capacitance

The UW type capacitors are compact models with 1/4 inch diameter shaft for low power RF system applications.
The UW type capacitors cover the capacitance range from 10pF (min) to 1500pF (max).

VH Type

Low/Medium/High Power RF System
Applications with Low Torque and Long Life

The VH type capacitors are the models intended to enhance their current capacities in high power RF System applications. MEIDEN offers five VH types that cover the current range from 100Arms to 170Arms.

• Double bellows…High power applications, low torque, and compact motors
• Low-loss ceramic envelope(82 or above), special copper alloy bellows…Low loss
• Reinforced capacitance adjustment screw

VT Type

Low Power RF System
Applications · Compact Size

The VT type capacitors are a compact model of former VM type capacitors with higher reliability. They are made to permit easier motor connections by placing a guide bearing inside them.

• Copper-plated single stainless bellows

VM Type

Low / Medium Power RF
System Applications

The VM type capacitors are the first model manufactured in 1992 based on MEIDEN’s long years of experience in vacuum technologies. They have a center pin allocated in the center of electrodes to secure an outstanding sliding motion in the vacuum. Double-layer bellows of high-strength stainless materials plated with highly conductive copper are adopted in the VM type capacitors.

• Copper-plated single stainless bellows
