Mining.com has recently reported that the price of tantalum, a precious metal, is on the rise. Several manufacturer’s of capacitors use tantalum as a dielectric because they are known to have high capacitance per volume and weight. Tantalum capacitors are also known to have lower equivalent series resistance (ESR), lower leakage and higher operating temperature than other capacitors. Currently, the price of tantalum is approximately $125 - $130 per pound; up from $100 per pound a year ago. While the price of tantalum has been volatile in the past, analyst are now predicting a 5% growth per year through 2020.

Oil-Filled capacitors have been used in a variety of applications for many years. They are most often used in high current and/or high voltage applications. Oil-filled capacitors are large in size when compared to other styles of capacitors because oil is a much thicker dielectric. In most oil-filled capacitors, the plates and dielectric are rolled tightly, insulated and sealed in a metal or glass container. Oil-filled is a commonly used term for any capacitor using a liquid filler to enhance the dielectric. Many types of oils have been used over the years, from mineral oil to synthetic oils. The addition of oil to the capacitor will improve its power factor. It is also used to cool the capacitor. Standard Radio has access to all of the major manufacturers of this type of capacitor as well as one of the industries largest inventories of oil-filled capacitors. Remember Standard Radio is a great source for every style of capacitor.
