RM10 bobbins with long pins

M

Hi,

I want to fit an RM10 to a 3.2mm thick pcb but the standard RM10
bobbin (12pin DIL style) only has pins 3.2mm long so they don't stick
out on the solder side.

Does anyone do such a part as a standard item? Also, the side clips
have pins for soldering into the PCB too. Same thing applies the
them, pin is too short to stick through to the other side. Anyone do
a long version of those?

TIA

Why do you want them to stick through the board? You will just have

If you have PTH you shouldn't have a problem. If you think vibration is
likely to be a problem, use an adhesive between the ferrite and the PCB.

Miles Platts bobbins have 4mm pins.

They should stick out a bit else it does not solder very well. You
have to get heat to pin not just the PCB. Current pins are too short.

Would a socket be out of the question? Just a thought.

Interesting thought but yes a socket would be a no-no.

I've got a 12 pin DIL RM10 bobbin in front of me & the pins measure
3.76mm long. It came from Neosid.

Thanks for the info. I wonder if there are any pips that keep the
frame a bit off the pcb and thus shorten the effective pin? I have
found some parts with 4mm plus pins but the one I have tried so far
doesn't stick out enough and that has 4.0mm pins (and a plastic pip).

The Philips (ferroxcube) bobbin for RM10 DIL has 4.3mm pins

CPV-RM10-1S-12PD

http://www.ferroxcube.com/prod/assets/rm10i.pdf

Non-DIL flavours have pins as long as 5.6mm.

You'll have to pay attention to assy and dress, in any event, so that
the core doesn't shove the bobbin off of it's intended mounting plane.

If you allow a large pre-tinned wetting area, in contact with the pins
on the wave side, you can aid in ensuring joint integrity. Lay parts
out with pins across the wave direction, not in-line. Be prepared to
inspect and touch-up.

Hi,

the Neosid ones do have very short pips right at the very edge of the
frame where they could be easily snipped off.
....unless you have thousands to do.

Those pips are to prevent a capillary slot forming between the former
and the board. Capillary slots are 'magnets' for all the contaminating
gunge in the neighbourhood.
