I have been researching the range of vintage
carbon resistors and metal film resistors. Please see the multi-page pdf which details more than 150 types giving ratings and sizes. Information is scarce for many manufacturers and is sometimes apparently conflicting. This can arise, for example, when sizes are quoted as either typical or maximum and when data changes through the product manufacturing life. Also colours are not consistent and marking styles can change. Power ratings are mostly given for free air at 70C, but de-rating figures are not always available. The power rating also depends on stability and reliability requirements. See HERE for the pdf. I would be grateful for any corrections or further data so as to provide best accuracy. I shall also be adding photographs later as a better means of identification. |

Vintage Erie Resistors - Carbon Resistors. Ceramic cased. See HERE (pdf) for types, sizes and ratings of the Erie range. Some available but only in some values limited values. Also some used available. Note that the actual resistance of these vintage resistors will often be outside the marked tolerances. Typically changes of +20% are to be expected. It is therefore possible to use alternative marked values to achieve the required ohmic value. |
