AMS enjoys excellent relationships with several suppliers that manufacture capacitors for many different applications. Whether high or low voltage, pulse discharge, RF, filtering, precision or wound film capacitors, AMS Technologies has the expertise and product range to meet your requirements. Our broad capacitor product portfolio ranges from ceramic capacitors for HF and high voltage operation and filter or snubber capacitors with electrolytic or polypropylene dielectrics to specialty vacuum/gas capacitors for high energy storage and pulse discharge all the way to capacitors for RF use or water-cooled devices rated to 4,000 kVA.
Designed for HF and high voltage operation and with a very broad capacitance range, AMS Technologies’ ceramic capacitors cater to all applications from antenna matching units to high voltage testing systems. Our product portfolio includes many different package forms, including the classical disc capacitor as well as the standard hockey puck package style (standard designs used frequently in antenna matching units as part of an active circuit that matches the RF generator to the load), with the extra subassemblies of daisy chain and ferris wheels. For high power applications there are also water-cooled ceramic capacitors rated to 4,000 kVA.
Filter capacitors are used in numerous applications, such as for maintaining power quality, in pulse forming networks, for snubbers and for filtering of output power. They are available in a wide range of sizes, package styles and power capabilities and encompass a voltage range spanning 16 V to 100 kV. By utilizing various dielectric systems such as electrolytic or polypropylene, and with a capacitance ranging from nanofarads up to millifarads, AMS Technologies can provide the right capacitor for most applications.
Capacitors for high energy storage, pulse discharge
These capacitors are an energy storage device. Many applications demand an energy storage device that is slowly charged but then discharged in a very short period of time (down to less than milliseconds), thus generating a pulse of electrical energy – like these capacitors. AMS Technologies can provide numerous solutions for your discharge capacitor needs, including commercially-priced products, variants with extreme high energy density, self-healing capabilities or very special shapes and designs. Custom designed capacitors tailored to your project’s requirements are also available on request.
High frequency capacitors
Specialised capacitors for RF use are available in many different variations (such as ceramic or evacuated) to match various applications. AMS Technologies has almost 30 years of experience in consulting and helping our customers to find the correct fixed or variable capacitor to suit their specific needs. Our ceramic disc and hockey puck HF capacitors use different ceramics, such as NPO, N750 and N3300, to yield specific characteristics (for example temperature coefficient). Our vaccum and gas filled capacitors (fixed and variable) are predominately used in antenna matching units, for applications like plasma generators, RF generators and for high power communication systems.
