Sangamo Electric Company Capacitors
April 1954 Radio & Television News

April 1954 Radio & TV News
April 1954 Radio & Television News Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

Sangamo Electric Company was a "heap" big name in capacitors in the realm in the middle of the last century. The company always featured an American Indian in its electronics magazine advertisements, and usually also included some form of "indian-ese" statements as part of the sales pitch. Of course such marketing schemes would be vehemently raided and those responsible figuratively "scalped," if you will pardon the gratuitous expressions. As with using names like the Washington Redskins, the Atlanta Braves, the Chicago Blackhawks, and the Cleveland Indians to appropriate and celebrate the bravery and might of the named peoples, Sangamo implied quality, durability, and reliability of its products through an association with American Indians. That does not matter to people who seek to create discord amongst the population while, in many cases, seeking notoriety and financial gain for themselves. Sangamo Electric was located in Marion, Illinois, an area where a few other uses of Sangamo are used, but I could not find any direct reference to a Sangamo tribe. President Lincoln addressed the people of Sangamo and Sangamo County, Illinois in newspaper articles while campaigning in the state (his pre-presidential era). The Sangamo Club has operated continuously in Springfield, IL, since 1890. There is some evidence that "Sangamo Country" at some point was redesignated "Sangamon County," the latter form being located where former was mentioned as having been.

Here are a few more examples of Samgamo advertisements in the September and December 1949, May 1950, April 1954, and June 1956 issues of Radio & Television News.

Live many seasons for heap good reasons

these wire lead tubular capacitors will not deteriorate with age

Use Sangamo dry tubular electrolytics for trouble-free replacements. You don't have to worry about premature failure. Long life is really built into these capacitors. They have exceptional staying power because:

1 A super-seal keeps the electrolyte from evaporating even under the toughest conditions of heat and humidity.

2 All these capacitors are aged at 85° C to build a tough dielectric film that will stand up under high heat.

3 All aluminum container prevents the "creeping" corrosion that occurs in capacitors when any other metal is permitted to contact the electrolyte.

4 Sangamo electrolyte is really pure. Continuous laboratory control of every batch keeps the chlorine ion concentration to less than 10 parts per million. That's 99.999% pure, or better!

5 No lead breakage.

Sangamo uses a special wire that resists bend fatigue. A specially designed rivet that "cradles" the lead gives additional protection.

 P. S. These wire lead tubulars fit those tight corners - Their compact design gives maximum capacity in minimum space. See your Sangamo Distributor for all your capacitor replacement needs.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
