fusible resistors

[pdul]

Anybody who knows a source for fusible resistors in Europe, Where you can shop as a private person?

I have bought some from Farnell.

Thanks. But unfortunately the Farnell i know of, Will only accept businesscostumers, And I am only a poor private solderiron swinger.

What value do you need? The ones I got were I think 2.2 ohm, 1 watt. I have no use for them now so if they are what you need you can have them.

Thanks for your kindness, But I need some 33 ohm, 1/4 watt. It is for an old amplifier, I am restoring. Maybe you know of an alternative solution/component?

both CPC and RS stock fusible resistors but not in that value Farnell seems to hold 2watt ones not 1/4 watt.
As a note, I've never had a problem buying online from farnell as a private individual, buy through the web and they accept credit cards

The tyco part is FRN25J33R 33R 0.25watt wire ended. Quite where you would get a small quantity (1 or 2 ) I don't know

I think the rest of world Farnell still has to catch up with the UK Farnell...

The US division of Farnell, Newark.com, is selling to me a complete nobody (with 40 years in electronics under various employers) with no minimum buy. They are even shipping to me like it was a business address, Euro 3 minimum via UPS. What is wrong with (I don't know flags except olympics) Norway? The US Newark before Farnell bought them used to have a business only policy, but when I logged on the website and furnished a debit card number with cash behind it, no problem.
As far as easy fusing, look at the wire tables in the National Electric code. Fusing current for 30 ga is about 1 amp and it goes down from there. You can look in the Belden or alpha catalog, figure out what the 7 strands of wire are in your 24 ga wire scrap from a PC power supply, strip out a single strand, solder 2 cm between two terminal strip lugs, instant low value fuse. Don't try this on mains wiring, use a real registered fuse and fuse holder.

I don't think that fusing current for 30 AWG is 1 Amp. As it can carry 2 Amps with PVC insulation and 4 Amps with Teflon insulation (80C & 200C).
My fusing current chart does not go to that small a wire. But if I did my mental math correctly, 30AWG should fuse at just about 7 Amps.
I didn't think that NEC listed fusing currents.

use the chart in the NEC, not my memory. I'm putting single strands in the transformer feeds to rectifier tubes. You can't even buy fuses rated that small, (200 ma) and they are certainly not rated for 475 V. 1/4 x 1 1/2 fuses only go up to 250 VAC. New rectifier tubes are not as failsafe as they were in the 1960's, and 475 v transformers are way more expensive.
