Recycling waste multilayer ceramic capacitors (MLCCs) is significant for environmental protection and resource recovery, which contain rich precious metals including palladium and silver.
What capacitors contain silver? Ceramic Capacitors or Disc Capacitors as they are generally called, are made by coating two sides of a small porcelain or ceramic disc with silver and are then stacked together to make a capacitor. For very low capacitance values a single ceramic disc of about 3-6mm is used.
Which capacitors have palladium? PGM ceramic capacitors are those capacitors with electrodes made from platinum group metals, which means they contain palladium.
Do ceramic capacitors contain palladium? Palladium is employed as an electrode material in multi-layer ceramic capacitors (MLCCs).
What electronics have the most palladium? According to the International Platinum Group Metals Association, in the electronics sector, most palladium is used for multi-layer ceramic (chip) capacitors (MLCC). MLCCs store energy in electronic devices such as broadcasting equipment, mobile telephones, computers, electronic lighting and high voltage circuits.
What is polystyrene capacitor? Polystyrene capacitors are capacitors that have a dielectric made up of polystyrene. They come only in low values, usually 10pF to 47nF. Normally, their tolerance is 5% to 10% but high precision polystyrene capacitors are also available with tolerances of 1% and 2%.

How much palladium is in a catalytic converter?
Although the quantities vary by model, on average, only one standard catalytic converter contains about 3-7 grams of platinum, 2-7 grams of palladium, 1-2 grams rhodium.
Does Canada produce palladium?
Canada doesn’t have much in the way of palladium production, with only one producer located in Ontario. However, the country does produce a small amount of the metal, and plays host to some exploration activity. North American Palladium is one of only two primary palladium producers in the world.
What is MLCC capacitor?
Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more.
How much palladium is in a MLCC?
Typically, Kemet’s MLCCs contain 25% palladium and 75% silver, according to Crowley.
Can I scrap capacitors?
You should be able to find a metal recycler in your area that accepts capacitors. Not all metal recyclers will take capacitors, but those that do are generally set up to check for oil contamination. There are also many household items that use capacitors that don’t contain oil.
Do VCRs have gold in them?
VCRs, CD Players and DVD players
Yet they too contain printed circuit boards that contain precious gold that is worth extracting.
What household items have platinum in it?
Platinum has often been used in cigarette boxes, lighter cases, cigarette and cigar holders, cigar cutters, and other smoking accessories. Now that smoking is becoming less popular, a number of these items are “washing back” onto the marketplace.
What scrap has platinum in it?
But the most common place to find Platinum in the scrap metal world would be in catalytic converters. Platinum along with two other precious metals called rhodium and palladium are the three metals that generally make up the insides of the catalytic converters to help exhausts cut down on the emissions.
What is polypropylene capacitor?
PP film capacitors are used for high-frequency high-power applications such as induction heating, for pulsed power energy discharge applications, and as AC capacitors for electrical distribution. The AC voltage ratings of these capacitors can range up to 400 kV.
What is polycarbonate capacitor?
Polycarbonate capacitors are capacitors that have a polycarbonate dielectric. Polycarbonate capacitors range in values from 100pF to 10µF, and have working voltages up to 400V DC. Their tolerance levels are 5% and 10%.
What does polystyrene look like?
Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point.
What is chip capacitor?
Chip capacitors are simply capacitors manufactured as integrated circuit (IC) devices, also known as chips or microchips. They are typically square or rectangular, with the length and width of the device determining its power rating.
What is mylar capacitor?
Mylar Capacitors a.k.a polyester capacitors (PET) are special type of capacitors with some unique features compared with ceramic and electrolytic capacitor. They can withstand high voltages in a relatively small package and provides high resistance against moisture.
Why are tantalum capacitors better than ceramic?
When looking at capacitance changes with applied voltage, tantalum capacitors show consistent stability whereas ceramic capacitors do not. In response to higher applied voltages, the permittivity of the dielectric shrinks within the ceramic capacitor and causes changes in capacitance.
