Strange resistor
2 Attachment(s)
I have found these resistors on a Japanese PCB from a high tech monitor.
Never saw them before, does someone know their quality ?
They are non magnetic, have about 5% tolerance and where used in the video circuits extensively.
A picture of some of them, compared to a normal 1/4W resistor :

do me a favour and measure them....with your meter...they are caps I think

Cheers!!The DIRTŪ

I measured them,
they are really resistors not caps !

Yup, capacitor markings don't usually have the "Omega" like
the upper right unit...

I recollect now...I had an old Blaupankt car stereo and it had them in it.....they might be useful for something

djmiddelkoop: Your devices look like Nikko-Ohm resistors to me. Probably the YQF series or something similar. The YQFs go for 40 yen per piece at Wakamatsu:

Similar plate-type resistors used to be made by Susumu, but they only make SMD components now.

thanks for the information.

do these plate-type resistors have any special qualities like low inductance or noise ?

As they were used in high speed video circuitry and are non-magnetic I want to use them for my audio projects.
Do you recommend them ?

I haven't used the Nikkos all that extensively, so I shouldn't comment. I did use the Susumus off and on, and these were quite reasonable, I felt. These were touted as being both low-noise and low-inductance. Measured distortion was also somewhat lower than average for a metal-film. _If_ the Nikkos are similar to the Susumus, then there should be no problem with using them.

Not needing to form the leads makes life easier during the building process. :)

I think (guessing) the main feature of these resistors are high voltage since they came from a monitor. Compare resistors from Caddock.
