Tantalum Capacitor Industry Needs New Resources

Tantalum Capacitor

Tantalum Capacitor

As the demand for tantalum has recorded 5% growth every year, the supply of tantalite has decreased setting up the electronic components industry with a possible shortage.

Tantalite, which is the key component of tantalum used to make tantalum capacitors, is mined primarily in three countries: Australia, Mozambique and Canada. Companies in those countries reduced or suspended production as the economy tanked in 2008 and consumer spending fell.

Recently, most production of tantalum has been taking place in Brazil and Africa but with the previous production facilities not producing the tantalum, a shortage through 2012 is possible.

What does that mean to consumers and companies that need tantalum capacitors?

Increased demand will push prices higher on current stock….and if current supplies are depleted, a shortage like the one that occurred in 2000 may occur pushing up prices even further.

Tantalum capacitors have grown in popularity for many reasons. To start with, tantalum capacitors have a larger volumetric efficiency when compared  to other types of capacitors. To illustrate this point, a 10uF tantalum can be used in place of a 100uF aluminum capacitor.

In addition, tantalum capacitors are able to be inserted on circuit boards easily. When you couple this with the tantalum capacitor’s greater  power dissipation characteristics when looking at other capacitors in this size range, tantalum capacitors  can be inserted in small spaces. This makes them good candidates for tightly designed boards. You will often find tantalum capacitors used in laptops, computers, cellular phones, auto circuits and other similarly sized electronic devices.

Another outstanding characteristic of tantalum capacitors is their nearly unrivaled life span. The shelf life of tantalum capacitors is unparalleled when looking at other capacitor types such as those made from electrolytic material since the performance qualities stay intact over time and they should not lose capacitance like many other popular capacitors.

A Console Stereo: Steve’s Legacy Project

We continue to be amazed at the work that our friend and customer from Canada, Steve White, does.

Luckily for us, Steve graciously shares his talents by allowing us to post pictures of his recent projects.

Here’s what Steve said about his console stereo:

If I were to ever to have a legacy, this project would have to be it! Ever since I was 5 years old I’ve wanted a console stereo. 38 years later and I finally have one.

I took 2 old Magnavox cabinets that were originally the same size (both same as the large one) and added to the larger one to accommodate the turntable, and shrunk the other to be a satellite speaker to allow you place it where ever you wanted to in your room to give you the true stereo separation.

I then painted the cabinets Jet black with ice-pearl sparkles. I wanted the tube amplifier to be displayed unlike in older consoles, right next to the turntable, because to me the amp is art! I then completely restored this 1962 Garrard turntable that was reclaimed from an old console, and put the whole thing together.

Here is the result…. Sounds really nice too!

Job well done, Steve!
