I have this PCB mounted fuse, RV16F, which measures 4.7 ohms on my ohmmeter test. It's on the 230V input to a device. The device draws less than 100mA, so I figure this is unlikely to cause a problem, but it's still a very high resistance for a fuse, or is it?

Re: Fuse marking RV16F
Try measuring with another meter. I'd expect zero ohms, maybe just a few tenths for the leadsSystem: HP xw6600 Workstation, 650W PSU | 2x Intel Xeon Quad E5440 @2.83GHz | 8x 1GB FB-DDR2 @ 667MHz | Kingston/Intel X25-M 160GB SSD | 2x 1TB Spinpoint F3, RAID0 | 1x 1TB Spinpoint F3, backup | ATI FireGL V7700 512MB | Sony Optiarc DVD +/-RW | Win 7 Ultimate x64 | 2x Dell UltraSharp U2410f | Dell E248WFP -
Re: Fuse marking RV16F
In fact it probably is your leads. Short them together and you will get 'value A' - then measure accross fuse for 'value B'. Subtract A from B to give C = resistance (if any) of fuse.System: HP xw6600 Workstation, 650W PSU | 2x Intel Xeon Quad E5440 @2.83GHz | 8x 1GB FB-DDR2 @ 667MHz | Kingston/Intel X25-M 160GB SSD | 2x 1TB Spinpoint F3, RAID0 | 1x 1TB Spinpoint F3, backup | ATI FireGL V7700 512MB | Sony Optiarc DVD +/-RW | Win 7 Ultimate x64 | 2x Dell UltraSharp U2410f | Dell E248WFPComment

Re: Fuse marking RV16F
Yeah that's OK with the leads then. I wouldn't worry too much about the fuse reading, it may even be a fusible resistor which are often found in circuit designs.System: HP xw6600 Workstation, 650W PSU | 2x Intel Xeon Quad E5440 @2.83GHz | 8x 1GB FB-DDR2 @ 667MHz | Kingston/Intel X25-M 160GB SSD | 2x 1TB Spinpoint F3, RAID0 | 1x 1TB Spinpoint F3, backup | ATI FireGL V7700 512MB | Sony Optiarc DVD +/-RW | Win 7 Ultimate x64 | 2x Dell UltraSharp U2410f | Dell E248WFPComment

Take a photoThats not a Fuhjyyu I used in your antec PSU its a HITACHI!! rofl lol lmao funni gui!Comment

Re: Fuse marking RV16F
It should be a Radial Leaded PTC Resettable Fuse.
Here is the datasheet.

Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the... -
hi all,
first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask
i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).
what i've found so far:
- the PSU does its job and supplies 12V to the mainboard via the connector.
- shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
- not far away, there's the first cap with a resistance of 0.7 ohms.... -
Hi guys,
I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.
How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.
Anybody know how to remove this type of fuse?
(The fuse is toward the bottom of the image labeled F2)... -
I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.
Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....
