Just how 'cheap' are you John?
Are you www.bgmicro.com cheap?
Here are some descriptions of some filters
on their web site:
- - - - - -
These Panasonic line filters can suppress conductive noise
ranging from low to high frequencies generated at power
supply circuits in various electronic equipment. These
line filters are excellent in high frequency characteristics
due to low stray capacitance realized by section windings.
Rated voltage Less than 250 Vrms.
Inductance 3.3 mH.
Rated current 4.2 Amps. Panasonic part number is ELF-18D850B.
PC board mount. DIGI-KEY's price $8.20, B.G.'s price:
(See also Panasonic data sheets)
PWR1025.. $1.19 or 10/$8.95
Same as above except manufactured by TDK.
PWR1026.. .99 or 10/$6.95

Subject: [RFI] super transformer dimmer
> dudes
> a question about triac interference
> >>>>>>>>have a 6 amp fan controller light dimmer. I want to use this for
transformer control in my new power supply . this unit shows very light
sizzling sound on local am radio station on the radio held on top of the
light dimmer. It Goes down somewhat when moved away [about 1 foot]. not a
big problem, but maybe am radio[1360kc] is not 7mc. I was also told years
ago that one may replace the small triac with a more hefty one and run more
current. sounds somewhat logical. I am also some what cheap. I will find a
1985 vintage microwave oven and use the 40 amp triac and heat sink unit from
one of those rather that buying a new one.[saves $20 or so and is more fun].
I also repair microwave ovens so it is second nature to use microwave parts.

> ?What does one normally do to kill triac interference? The fan dimmer has
a small coil and and some other small parts. could the coil be part of a
current noise suppression network?
