Resistor Array BGA Package

A new page was just added to cover a BGA Resistor Array. The new Resistor Array is linked off the main Resistor Network page, which really covers a resistor network in a 16-pin DIP. I also added a link off the page covering Resistor Array Manufacturers, cause it seems like many of the other resistor network links are on that page.

I also added the page link to the SiteMap for the web site too.

None of these pages covering this topic are doing well. It could just be there is not a lot of search traffic for resistor network packages.

Looks like the last time I added a page to this topic was on Jan 12, as Resistor Networks. Then on Dec 3 as a DLCC Resistor Array. I've been slowly been added to this topic over the last few months.

I also up-dated the new Google search bar, if you happen to be following the other blog. The site search should work the same but the search bar looks a little different.

Panel Mount Fuse Holders

I added a another page the other day, but because I didn't think it would ever produce any visits I waited till today before I blogged about it. Plus I just used all the other related links in the last posting. Anyway, the new page addressed Panel Mount Fuse Holders. Much of the text is a copy from another page, so until I update the listing it will never do well.

I also added another page which contain zero text; Panel Mount Components. Not sure why I added this page, but it is a new page ~ it will be one of those pages that never gets 365 views a year, I already have to many of those.

As with the other new additions, the new page address have been added to the html sitemap. Although they will not be added to the xml sitemap used by the search engines, as I only up-load a new xml sitemap every 3 months or so. But Google should be able to find the new pages regardless.

I still have a number of pic files I want to add to the site, so the next new page address will relate to one of those graphic files I have.

Chassis Mount Fuseholders

Added a few new pages to Google-sites today to hold some graphics of; Panelmount Fuse Holders, Extractor style Fuse Holders, and a different view of a Panel-Mount fuse holder.

Now I don't normally add a blog posting for new pages to google-sites, but I had added a few new engineering pages to interface-bus and listed them within one blog posting. Not so bad but I use the Blog Archive on the left of the page to count the number of new pages. So the count is off when I add more than one page to a posting. Any how I'm using this posting to address pages on another site to make up for a lack of counting on the main site.

There are a number of pages related to Fuses on the main site, those graphics were a bit to large to add. So;
Fuse Vendors.
DC Operation of Fuses.
Fuse Holder Manufacturers.
Fuse Holders in Chassis Design.
Fuse Derating Recommendations.
Fusible Resistors.
Fuse Definition.

There my even be a few more pages related to fuses, but these have the highest ratings in a site-search. Oh the newest of the pages, Fuse Blocks, is doing the worst with only 13 page views this year. The next worst is the page relating to panel mount fuses used in chassis design.

Capacitor Characteristics

A new page providing a graph of Altitude vs Capacitor Operating voltage was added. Of course it shows the capacitor case sizes which kind of also define the operating voltage. A small amount of text was also added to support the chart, but it's not much additional data yet.

Another new page was added to address Capacitor Insertion Loss. The Insertion Loss page is linked off the capacitor dictionary page starting with the Impedance Definition. This page has even less text than the other new page, but this always changes over time. The interesting thing is that the site analytics does not even show any page views yet, and I generated this page three days ago.

I also added both capacitor pages to the engineering site-map, keeping that page up to date. The site map lists all the pages contained on the Engineering Web-Site. I also found a few duplicate entries in the site map, so those got deleted, and I also added a bit of supporting text to some of the page listings.

So it appears that the capacitor dictionary section contains 19 pages, with some number of supporting pages. Of course there is also a number of pages that discuss characteristics of capacitors, sizes, MIL Spec, tolerance and so on.

555 Circuit Diagrams

Yet another 555 schematic was added yesterday. Another Astable Multivibrator 555 circuit, linked off the main 555 Timer Introduction page. This one uses to different circuit paths two charge and discharge the timing capacitor.

I've been calling the listing a Individual Pulse Width Adjustment circuit, but maybe a High-Low Pulse Width Adjustment circuit would be better. At any rate it's a variation of an Astable 555 configuration, but with each of these circuit additions it has more and more circuit elements.

I just generated this schematic graphic, but I think I have one other, so I may yet start another related page address ~ about another 555 circuit.

The next post will be about Capacitor stuff, because I added two other pages the other day but have yet to blog about them.
