The V9000 Sapphire trimmer capacitor has been launched by Voltronics, with the company claiming that the capacitor is unique in design and offers the highest working voltage rating (2 kV) for its size. Measuring at 0.64“ (at minimum capacitance) in length, the capacitor delivers a capacitance range of 1 to 12pF.

Sapphire is suited for precision trimmer capacitors as its dielectric constant is extremely stable, measuring below 0.0003 up to 10 GHz, and is chemically inert; totally moisture resistant and mechanically strong. These trimmers have a high Q (3000 min at 100MHz); DC working voltage of 2000V and DC withstand of 3000V. They are also compatible with SAC 305 reflow processing.

The V9000 Series is specifically designed for the MRI industry where its size, power, capacitance range and affordability make it the preferred choice for the next generation of coils. Due to the severe non-magnetism requirements this industry requires we use only materials that exhibit no measurable magnetism - commercial brass and plating materials are not acceptable. Our strict traceability and testing regimes ensure this essential parameter.
