		<description><![CDATA[In a previous blog I commented on First Mate Last Break (FMLB) power and signal pins, also known as hot-plugging. A connector design in which power contacts engage before signal contacts when two connector halves are mated, FMLB prevents damage to electrical circuitry in the system by having the ground pin mate first, followed by the power pin, and finally by the signal pins. ]]></description>

		<description><![CDATA[In this age of acronyms, FMLB or LMFB (or do you say FBLM?) are favorites in the power supply world.

‘First mate last break’ is a feature that provides for a longer than normal power blade or signal pin. Typical uses are i.e., as a long, or first mate, power blade for grounding the system before the hot power blades are engaged. Or a long signal pin may serve as a warning to the system that the power supply is about to be fully engaged and launching watts at its waiting functions. OTOH (on the other hand), ‘last mate first break’ provides a short pin as a possible warning that the system is about to be shut down.]]></description>

		<description><![CDATA[As gas continues the march toward $5 per gallon, there are more and more headlines on electric vehicles.  And with that, high current batteries.  I have been talking to many in the industry on the new requirements for connectors in this evolving high-current market and one thing is jumping out. The concept of rating these proposed harness products for temperature and T rise is anything but clear!]]></description>

		<description><![CDATA[Not long after I started my current Molex assignment of developing new power connectors, I asked a customer about the airflow environment around a connector. His first reaction was to say “Never you mind about airflow, that’s my safety net!” He thought I was suggesting that we could re-rate the connector temperature rise using the cooling effects of the airflow from system fans. And so I learned never to even suggest that the T rise of a connector could be favorably influenced by system cooling fans.]]></description>

		<description><![CDATA[When I first got involved in Power connectors, one of the first things I noticed was there were a lot of “hybrid” connectors. Meaning a single connector had both power and signal contacts. At first I panicked. Omigosh, I thought. I am not only going to have to catch up on the power connector market after working in other connector markets for 20 years, but I was faced with learning about signal integrity. Terms like skew, FEXT and insertion loss danced through my head.]]></description>

		<description><![CDATA[In the connector world, quoting prices in terms of price per line is very common. It is simple, straightforward, and as long as that number is going down year-over-year, customers are happy! Power connectors aren’t good for per line pricing estimates. The reason being that they are often hybrid, containing a mix of contacts that [...]]]></description>

		<description><![CDATA[The practice of derating power connectors has been varied among users for decades.  Back in the day, (yes, I am over 50!) many users took a simple approach, assigning an arbitrary percentage to the current carrying capability – we’ll call it the C³ or C cubed factor.  So if a connector supplier submitted a product that was rated at say 100 amps, then a user would factor by say 30%. The idea was that since this is a huge safety issue, no one wanted to take any chances that a power connector may over heat.]]></description>
