Manufacturers of Coaxial Cable

I added a new page off the wire/cable manufacturers page. The cable manufacturers page has always been to large, and I've been moving sections off the main page for a few months. The new page that covers the listing is located on the Coaxial Cable Manufacturers page.

I put links on it to a few other pages, including a better definition of Coax cable, and a link to How-to-Derate Cable based on temperature rise. The chart of Operation Frequency ranges for connectors may also be of interest.

Not sure, but I also added a listing for an MC-10 serial interface ~ obsolete. Guess I need to check the external link report again

Resistor Chip Attenuator Manufacturers

Following yesterdays posting of Manufacturers of Current Sense Resistors, a new page was added providing a listing for Resistor Chip Attenuator Manufacturers. Both pages are linked of the main Resistor Manufacturers page, and all three pages should be cross-linked.

There are other sub pages linked from the resistor pages that do not contain a link to either of the new pages;
Manufacturers of Potentiometers,
Manufacturers of Thermistors,
Manufacturers of Varistors,
Manufacturers of Semiconductor Resistors.

Never had a chance to design a circuit using a Current Sense Resistor, but it's hard to design a board with out an attenuator. However, always having a small amount of free space I don't purchase a new device to make an attenuator. I reuse the same resistors already used on the part list if possible. Why add a new line item, if you can avoid it. Of course for that to work, you need to be using many different resistor values.

Always add to the quantity of a line item rather than adding a new line item. New line items always cost more.

Oh the top listing for electronic component Manufacturers, or Passive Circuit Design data.

Current Sense Resistor Manufacturers

A new page has been added to cover Resistor Current Sense Manufacturers. The link was added off the main page for Resistor Manufacturers.

Current Sense Resistors are used to draw off current from another circuit but drop no voltage, these are very low ohm devices. Some current sense devices may be surface mount devices and low power or free-air high power devices.

The new page was started from the main resistor page, same but fewer links with a different description.

Like any other page; this new page may see a lot of traffic or not as there is no way to tell. Assume 15 to 30 days to get spidered, than another 4 months to get a page rank. In any case the page is linked from the Resistor Manufacturers page. In any case it rounds out the devices produced that function as resistors.

As a side not, the posting's on this blog indicates the number of new web site page postings. A few posting may not provide a new page, but many have more than one......

milli-ohm resistors; chip resistors and free air resistors. High-Power Low-Ohm Resistors.

How to Design an Equipment Chassis

I produced a section of pages back in 2005 relating to Electronic Equipment Chassis Design.

The attached pic shows total page hits for that section from the middle of 2006 on, and the top 10 producing pages. Although it says 86 URL's, there really are only 42 pages. Looks like the section get about 50 to 150 page views a week. With about 16,000 page views in 2007.

Any way I'm out up-dating the search bar on those pages and notice [again] that a number of pages have no page rank any longer. I posted a related entry in the main blog "pages losing ranking". Looks like about 10 pages no longer have a page ranking from Google. Here are those page links:
Equipment Racks Shelfs.
Equipment Rack Casters.
Panel Meter Manufacturers.
Equipment Chassis Slot Keying.
Chassis Connector Types.
Elapsed Time Indicates.
Rack Mount Environmental Alarm Manufacturers.
Chassis Cable Assemblies.
Electronic Terms for Equipment Chassis.
Page two of Chassis Terms.

The only thing I can figure is that because these pages get so few page hits, that they lost their page rank. Internal Pages point to them, and via the sitemap, external pages point to them. And now this blog points to them.

These pages help to round out the How-to section, so I don't really mind that they my be getting just a few page views. I would rather have the page there for someone than not have it...
