I am looking to source a number of pcb mounted low profile 16 volt dc SPDT mechanical relays, I am finding plenty of 12 volt examples but am not finding any 16volt packages.
Thanking you in advance

Re: PCB SPDT relay(s)
Do you mean 16V coil or 16V contacts?
16V is a very unusual coil voltage, I'm not surprised you can't find any. Maybe it is a 12V circuit and the 12's will work fine. Or if not, a 15V coil will work fine. Maybe you can modify the circuit to go with 12 or 15V.
If it's a contact voltage, you can always go higher. -
Re: PCB SPDT relay(s)
Coil voltage apparently, to be honest I was going to use 15 volt but am struggling to find that in a pcb mount low profile package as well.Comment

Re: PCB SPDT relay(s)
Who is the maker of the current 16 volt relay you are replacing?
Also, could you use a resister in series with the coil to drop the voltage to the coil to 12V and use a 12 volt relay?Comment

Re: PCB SPDT relay(s)
Take a look at a few datasheets. A 12V relay actually has a very broad range of operations. Most will turn on at 75-80% of the rating and be able to handle a minimum of 150% of the rated coil voltage. Not knowing your exact app and configuration you could start with something like an Omron G5LE series which are rated to up to 175% coil voltage. Probably want to stay away from automotive relays which usually have a max coil rating around 16V.Comment

Re: PCB SPDT relay(s)
As soon as I have that information will add it, for now I have a number of commercial dishwasher boards coming in for repair and the customer has advised me they are fitted out with 16 volt low profile spdt relays. As soon as they turn up I will take a look at the working voltage to the coil pack and make a decision about what I am going to replace them with as I have yet to find any with coil voltages as per the above mentioned.

Re: PCB SPDT relay(s)
We need to find out if the 16vdc is for relay coil rating or the relay contact rating.
For example, this one has 16 VDC contacts rating.

Re: PCB SPDT relay(s)
Most likely if you contact these people you will find your part. http://www.hobartuk.com/parts-accessoriesComment

Re: PCB SPDT relay(s)
Not to be a smartass, but why not just get the part number off the relay?Comment

Re: PCB SPDT relay(s)
There are many relays on that board.

Re: PCB SPDT relay(s)
They seem to think its the pump relay (the one furthest right in the above picture) that has failed, and while it is a common failure mode for these boards it usually turns out to be the BTA16-600B ST TRIAC that drives pump. When the boards turn up I will get the part number as I don't have a high enough resolution pic to read the part number off. They are very expensive boards to obtain, I have been offering a repair service for these types of controller boards for several years.
Thanks for your assistanceLast edited by llonen; 02-01-2017, 11:25 PM.Comment

Re: PCB SPDT relay(s)
To bring this thread to a close I have obtained the part number for the relay in question, it turns out the customer was confusing the switched contact rating with coil pack voltage (I think) anyways the relay in question is a HF115F which according to the data sheets is likely to have a nominal rating of 12 volts, and is readily available.
Again thank you for your assistance.Comment

Re: PCB SPDT relay(s)
The customer probably got the info from internet but have no knowledge about the relay or how to read the labels.

Re: PCB SPDT relay(s)
So there are operating voltages and rated voltage on relay coils. You will noticed that the rated voltage of a relay coil is 24 volts but its operating voltage is 16.8 volts. https://cdn.badcaps-static.com/pdfs/...e7147a3dcb.pdfComment

I have old game console which have connected to 220v outlet by previous owner and It is not able to turn on.
I checked continuity of fuse in PSU unit with a multimeter which is shown in the below picture with a orange circle around it, and It seems that fuse became open circuit.
I also found that as well as bulging capacitor, there is unidentified coil which has residue all over its surface

Hi to all 😎
I'm looking for any useful information to repair this interface (I have attached the image).
On this board I read E3215-1215A_4D.
This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.
If any of you have found a burnt or short-circuited component in a circuit like mine​, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.

Hi everyone
I'm struggling to point out what part is this? It is a coil, but the parameters say: 10OHM - 50% - 1A - 0.05Ohm
So it is a coil with 0201 dimensions, 1A max current, 0.05ohm resistance but what is 10ohm? For a coil we need specs like 1uH or so.
IAny ideas? It is from a MacBook A2681
Thank you... -
Hi all, the PSU originally had a no 12v issue where as soon as I bridged the 5v standby to the ACDC_stby the psu would switch itself off completely. I monitored the voltage on the main filter caps while doing this and saw that the PFC was bringing the voltage up to around 360vdc before shutting down. Given that I saw that as a little low I replaced the PFC feedback resistors from a donor PSU and that got it to power on, without a load no coil whine is present and there is a stable 12v however as soon as I put it in the PS4 it starts whining really badly, however 12v remains stable but after a... -
I have a CD unit which is came from saturn game console.
It always perceived Any retail CD or CD-R as Audio-CD.
Of course I changed laser head and adjust pot of laser head nearby, but It always failed to perceive as saturn game CD.
I think that this problem probably begins When I tighten IFT coil too hard with small screw driver and suddenly I heard some kind of snap or cracking sound
I desoldered this IFT coil and It is 7pin IFT coil and written "4120 009 62VK" on the surface.
Is there any way to identify its frequency in order...11-11-2022, 05:31 AM
