Re: Pcb Markings - what component is ep ?
G,
Best guess is it's an SMT edition of a self healing fuse.
But I can be wrong.

I get no connection on these, my fluke measures nothing.Comment

These are for anti-static protector like the VR in other devices. They short the spikes to ground, all of them are grounded. Good thing to do.

If I want to buy these on Rs components what will I look for and how do I measure these ?Comment

Re: Pcb Markings - what component is ep ?
The resistors? The marking on these SMD itself says resistance value.
The other compoenents that is capacitors and protective devices like this should be open circuit. For zener it acts like diode when checked both ways.
That all, cheers, WizardComment

No, I meant the anti static smd protectors - I allready got smd caps and resistors.Comment

Hello experts,
I recently purchased a used Fluke 123 Industrial Scopemeter from an online Japanese auction site (jauce.com). It has now been delivered. Unfortunately, I overlooked the fact that the seller neither guarantees its working condition nor accepts returns.
When I power it on, the backlight comes on, but there is no image on the screen. After opening the device, I noticed clear signs of previous soldering in several areas (photos attached). It seems someone attempted repairs before.
At this point, I'll have to try and fix it myself. Has anyone here... -
I am repairing a Fluke 335 clamp meter. After contacting fluke it appears there is no service manual or circuit board/ component list available. I have determined that there us a faulty PNP bipolar junction transistors shown in the pictures. I am having trouble sourcing this transistor. I pulled a good one off of the board and tested it with my component analyzer but I cannot find anything that matches the specifications. Any help locating this part or a replacement would be greatly appreciated.
Thanks... -
Need a new (used) DMM and there are two in the area for resonable prices.
The Agilent U1242A is 63 GBP (about 80 USD)

The Fluke 179 is 55 GBP (roughly $68.00)

Kinda leaning towards the Agilent.
Anyone think that is a bad idea? -
Hi,
i'm looking for a component from the picture with marking "JWCXJ 2HB1N" it is just after Ethernet IC.... -
Hello.
I need help in identifying a component. It appears to be 3 pin fuse, marking SEFUSE D5T4YB, but i cannot find any information about it. Taken out of DELL XCMRD 14.8V battery board.
Thanks in advance.
Edit: Got told its D6T, because there was still more gunk on it. Sorry for bother and thanks.01-31-2025, 12:58 AM
