The UW series is a compact size model developed for RF applications of the power output 5 kW class or less. It is a long life type using the screws with the longer product life - about 2 times of that of our VM type.
- We realized the low loss and high strength by using copper plated stainless steel.
- Our original high precision spiral electrodes are in use.
- Product line-ups that can cover a wider capacitance: from a minimum of 3 pF to a maximum of 2,000 pF.
- We realized low loss by adopting a high alumina ceramic (UWA55 type)
- We realized a long life by diamond like carbon (DLC) coating
Please refer to the catalog for any caution in handling and operating and explanations of characteristics.

• Low-loss and high durability bellows
• Spiral electrodes
• Wide capacitance range
• Adoption of a high alumina ceramic
• Adoption of stronger screw for variable capacitance

Compact size ball screw

A compact size ball screw is adopted as the screw for variable capacitance.
We realized long life to meet the conditions: over-loaded conditions such as high speed and hgh acceleration and deceleration inversion matching, continuous operation in the same range, and slight hunting.

• Solar power application
• Maximum allowable current: 50 Arms
  
• Allowable surface temperature: 80℃
• No silver plating
