How passive components work

Electronics Forum | Thu Dec 15 07:38:33 EST 2016 | emeto

Passive components are the one's that don't gain power on the output. The one's that do are called active components. Diodes, resistors, caps and inductors are examples of passive. Transistor is active component.

As their name suggests, Passive components are electrical components that do not require any ... circuits that require to be powered in some way to make them work..

Passive SMD components codification

Hi, Does anyone knows if there are any standards about passive smd components codification? Or each component manufacturer creates is own conding? Do they follow any rules? Thanks, Alberto

Alberto: There's no rules, but it works sorta like this: RESISTORS Usually marked in ohms using a standard code: First two numbers is the value Third number is the multiplier 102 = 1.0 x 10� ohm = 1000 ohm = 1 kW CAPACITOR Usually not marked. When

I am looking for more information about: 1) What kind of evaluation can I do to measure the resistance to fall off of a bottom side glueded SMT component?; 2) There is some influence of doble wave solder machine (temperature, flux, etc) i

Solder Short in the passives components in the Solder Side

Electronics Forum | Tue Sep 23 09:18:45 EDT 2003 | russ

IPC SM 782 has some info on wave solder pad geometries. We usually like .03" spacing to any uncommon conductors. I would assume that you are seeing shorts between components and vias or adjacent parts? Russ

Solder Short in the passives components in the Solder Side

Electronics Forum | Fri Sep 19 15:51:01 EDT 2003 | David Bonilla

Hi I am having solder short defects on the bottom side with SMD devices that run through the Wave solder. May you let me know any IPC guildelines about the spacing, orientation or any other design guidelines for avoid solder defects with SMD device

lead free components in leaded process

Electronics Forum | Fri Jul 20 08:09:09 EDT 2007 | chrispy1963

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th
