    100K capacitor = 100pf?

    Any chance for a picture of the markings and cap. May clear up some options!

    100K capacitor = 100pf?

    100k could be correct for 100pF. Some caps only change to the 3 digit when they go over the 100pF rating. So a 10pF would be marked as only 10 and the K would be tolerance 10%.

    Newbie - attempting to repair Ford circuit board

    There are automotive grade caps. Often you will see them noted with an AEC-Q200 certification or noted for automotive applications. I would not change the composition of the cap, however you are generally ok to raise the temp and the voltage. I generally recommend this when someone has issues...

    Well there's your problem! Can you help me identify this part?

    I used a google search looking for Diode marking AXJ. and then looked through the TSC recognizing their symbol. I work for Digi-Key and spend a lot of time helping people identify parts and crosses so I get a lot of practice.

    Sewing machine power supply/capacitor blown up

    So just based off measurements you provided and the series number it would lead me to look at part PME271M568MR30 18.5mm x 7.8mm x 13.5mm 15.2mm lead spacing

    Sewing machine power supply/capacitor blown up

    I don't have any information on the machine itself. Only option I have would be to get the measurements as Steve said and look at the series. Can you get the following Lead spacing. Height off board. LxW

    Sewing machine power supply/capacitor blown up

    I can't read all the numbers on the folded side. I know the PME271M is a series of caps that you can buy almost any where. https://www.digikey.com/short/jpfmtt is a link to the series from Digikey. I think there are some numbers on the right side of the pic I can not see that may be able to help.

    Hello, I need help connecting an C8051F130 Silicon Labs Microcontroller to a Silicon Labs USB DEBUG

    @Jerry Houston are you using the Targetboard or are you just trying to hook-up to the chip?

    SMD components help.

    I believe the first one is a BAT54S The marking for this part is a *V4 and the * is an indication of country of manufacturer. If I remember right W=China.

    LED specification - All about 3mm & 5mm LED's

    I agree with Bob you can not try to make a chart when there is no standard set for these specifications. The information you already have may be considered "Common Values" but by no means would be reference material. i.e. Broadcom 3mm red LED HLMP-1700-B0002 is 1.7V 2mA 50° 626nm 2.1mcd and...

    Name of this connector please?

    Take a look at this JST PLUG 455-2265-ND looks pretty close. Would have to check dimensions. https://www.digikey.com/product-detail/en/jst-sales-america-inc/PHDR-08VS/455-2265-ND/1166102

    Electrolytic capacitor identification

    While I have not identified the exact cap from my previous searches I agree with @hevans1944 405 is likely a dat code 05 month of 2004 220 is likely 220uF 50Z is going to be 50volts and then Z will either be a tolerance or series indicator

    What is this?

    Little Fuse makes TVS Diodes. Can't find the 30C marking that would be the identifier. https://www.digikey.com/short/qjhfwf Found it Littelfuse part number P4SMA30CA Digi-Key does not carry that one, but looks like this one from Vishay may work. P4SMA30CA-E3/61...
