    End-of-life (EOL) product announcements are a ritual of the electronics industry. When newer, smaller and faster are the watchwords of new products, at some point the older, slower, larger pieces fall by the wayside, are rendered obsolete and bypassed by newer technology. It’s a fact of life and we’ve become accustom to it. So when Panasonic released the announcement stating they were exiting the aluminum snap-in capacitor business, it may have been overlooked by many in the industry. But, this is one EOL announcement to pay attention to.

    Panasonic has manufactured excellent snap-in capacitors for years, they have been some of the most high-performance components in this product category. Keep reading...

Capacitor Components

Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors Aluminum electrolytic capacitors are cost effective solutions for high voltage and capacitance applications in relatively small case sizes. There are five common configurations of aluminum capacitors: axial, radial, large can (computer grade), snap-ins and surface mount.

Ceramic Capacitors

Ceramic Capacitors Because of its outstanding versatility, ceramic capacitors are the most widely used capacitor dielectric. It can often duplicate, and in some instances, surpass the electrical and environmental characteristics of other dielectrics. The wide range of dielectric constant gives ceramic dielectric capacitors a notable advantage in microminiaturization. Their ability to operate over a wide temperature range and to be formed into an unlimited variety of shapes and sizes gives them both mechanical and electrical design possibilities not available with other dielectric materials. The most common types of ceramic capacitors are multi-layered ceramic chips (MLCC), surface mount, radial and axial leaded MLC, disc capacitors and trimmer capacitors.

Film Capacitors

Film Capacitors There are basically two manufacturing methods for film capacitors: film/foil and metallized film. Both methods offer a variety of dielectrics, voltage ranges and capacitance ranges. Film capacitors are typically chosen over ceramic, tantalum or aluminum in applications requiring both non-polar operation and high electrical efficiency. The type of film material used depends on the particular application and electrical performance required; the most popular materials are polyester and polypropylene. The combination of dielectric materials and the structure of the electrode (foil or vacuum deposit) are what distinguish film capacitors from one another.

Mica Capacitors

Mica Capacitors Mica capacitors are extremely stable against heat, high insulation resistance and breakdown voltage, which provide an ideal dielectric for use in circuits requiring precise frequency filtering, bypassing and coupling. Mica capacitors maintain unusually high voltage and capacitance stability when subjected to considerable changes in operating temperature. They are the preferred dielectric in high temperature and high frequency applications. Mica capacitors are available as radial leaded, epoxy dipped in commercial, military and e-rel versions as well as the surface mount MC commercial chips.

Muti-Layered Ceramic Capacitors (MLCC)

Muti-Layered Ceramic Capacitors MLCCs are used primarily in applications where small physical size is needed along with relatively large electrical capacitance. MLCCs are available in a wide range of capacitance, voltage, tolerance and termination options and have a low cost compared to other capacitors. High capacitance values of MLCC’s are made by increasing the number of electrode layers, and by decreasing the thickness of the dielectric layers.

Tantalum Capacitors

Tantalum Capacitors Tantalum capacitors are the most stable electrolytic capacitors known today, and are extremely valuable in electronics, aerospace and medical industries. Tantalum capacitors have the greatest capacitance capability for their size of any capacitor. Tantalum capacitors are available in two basic constructions, solid electrolyte (solid slug) and wet electrolyte (wet slug). Wet slugs are used where the lowest DC leakage is required, and solids are used in applications where size restrictions exist.

Things to Consider

  • Type of dielectric
  • Capacitance required
  • Temperature and Frequency rating
  • Voltage rating
  • Dielectric constant
  • Tolerance
  • Polarized or non-polarized
  • Surface mount or leaded
