Capacitors

Midas EMC offers a comprehensive range of Capacitors manufactured by Spectrum Control such as Film Capacitors, Tubular Feed-Through (FT) and Pi Capacitors, Switch Mode Power Supply (SMPS) Capacitors, Planar Capacitors and Discoidal Capacitors. 
 
The Film Capacitor product line encompasses a broad range of capabilities from standard end wrap and fill, to completely custom designs. Available with dielectric options such as Polypropylene, Polyester (Mylar) and Polyphenylene Sulphide (PPS) the flexibility of the range means close to any customisation is available. Used in military and commercial applications the capacitors have a VDC ranging from 250VDC-1200VDC with ripple currents available up to 400 Arms. Geometries include cylindrical, flat, modular or oval-wound. Housings are available in various materials, whilst just about any cap of current value is obtainable. Custom designs are available.  
 
Tubular Feed-Through and Pi Capacitors are small in size, lightweight, non-polar and offer high dielectric strength allowing them to be ideally suited for by-pass and filtering applications. All capacitors are fired to produce true monolithic structures, which are impervious to moisture and contamination. Outer terminations feature a nickel barrier and a final metal layer, typically silver. Operating temperatures of -55C to +125C are achieved with no voltage de-rating. Due to the cylindrical design the capacitors have a low inductance compared to conventional wound capacitors. Custom designs are available.  
 
Discoidal Capacitors provide great versatility in meeting varied voltage, capacitance and dimensional requirements. The capacitors are nonpolar, small, reliable and high in dielectric strength. These parts are ideally suited for by-pass and filtering applications and perform extremely well in high frequency applications. With a low profile and rugged design, these are an excellent alternative to ceramic tubes. Operating temperatures range from -55C to +125C with custom designs available throughout the series. 
 
Planar Capacitor array many advantages such as having a low profile, are compact and have quick assembly times. Suitable for use in filtered connectors the capacitors have an operating temperature of -55C to 125C. Various custom and industry standard geometries are available with designs that can incorporate multiple capacitance levels, feed-through and ground holes. Available dielectrics contain EIA Codes: NP0 (COG), X7R, Z5U whilst customisations are available throughout the series. 
 
When compared to other capacitive elements, Switch Mode Power Supply (SMPS) Capacitors boast lower equivalent series resistance, lower equivalent series inductance, lower ripple voltage and less self-heating with capacitance values ranging from 0.01uF to 47uF. The capacitors have 3 different case sizes available dependant on your requirements with the option of 3, 4 or 10 leads with terminations including leads in, leads out and straight leaded. Voltage ratings range from 25 VDC to 500 VDC. Custom parts are available.
