Hi,
These inductors seems to work good I think in a power supply
Anyone got an opinion about these coils?
These are originally used for speakers.

Tritec coils
blank,
I´ve looked at them for my upcoming Aleph-X but think they´ve got a bit too much dc-resistance (0.24R), are a bit too big and probably a waiste of money for a Pi-filter. (2.2mH)
After a bit of searching I think I´ll buy some "torobar" chokes (also from Intertechnik) wich have much lower dc-resistance (0.12), a saturation current of almost 11A, are a lot smaller and only cost a fraction of the tritecs.

I looked at http://www.intertechnik.de/cgi-local/shop3_blatt.pl?1340580 and there are the data of the torobars

Disculpe Sorry Entschuldigung. Ich hatte es nicht gesehen.
Thanks for the link. Interesting supplier.

Hi,
I am using Intertechnik I-Point Coils with 3.9 mH and 0,16 Ohm resistance...
http://www.schuro.de/Downloads/PDF-Preislisten/Intertechnik/I-Punkt_I_BR.PDF
They are cheap (about € 8.00 = $ 8.00) and according to Intertechnik they can handle high amounts of current without satturation. They are a bit long though...
Greetings,
Lucas.

Hi william,
the Torobar chokes have a lower dc-resistance as 0.12, dont they?
Have a look

Or am i wrong?

I think they made some error. On the Intertechnik site you see other DCR values. E.g 0.12 ohm for 2.2 mH.
Hi,
For my AlephX-200 I want to use this schematic.
http://web.vip.hr/pcb-design.vip/power-2.html
Of course the values in the schematic are not correct for a AlephX so here are the values that I am going to use:
Voltage rails: +31V/-31V
Bias current: 8A
Capacitors: 8x47000uF
coils: 3.9mH
For the choise of the 3.9mH coils I looked at the torobars and the tritecs. The torobars are cheaper and have a lower resistance but the only thing that worries me is the saturation current. According to the specs. the torobars have a saturation current of 11.5 amps. According to the specs. the tritecs don't have a saturation current.
How important is the saturation current for coils when using them for a psu? And can I use the torobar coils for my psu?
