Does anyone know if there are metal film resistors of 1% fake? Many offers on ebay from sellers in China and Hong Kong selling kits for a very low price.

Re: Counterfeit resistors
EEVBlog has two very good recent videos where he compares brand name quality resistors with their Chinese counterparts... Unfortunately, when he got to comparing the off-brand metal film resistors, his DMM software crashed..."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

But his video on the micro-current meter showed that even good brand name resistors aren't always what they appear!"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Check out the last two videos, #215 and #216."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

Re: Counterfeit resistors
I would, but I already chewed through this month's data allowance and now have 64kbps for the next 2 weeks

Argh! Well, at least it's warm in New Zealand."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

Re: Counterfeit resistors
1% resistors don't come down a different assembly line.Originally posted by Tioleco View Post
They have Chinese girls armed with DMM's [ones made especially for grading] that measure them as they come off the line.
The ones that are within 1% go in the 1% box.
The ones that are within 2% go in the 2% box.
... And so on..

Re: Counterfeit resistors
So warm it means I can't count, apparently. Made an error on my usage calculations and somehow 'lost' 13GB...Originally posted by mockingbird View Post"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Counterfeit resistors
I can vouch for Sun-Pec. Ordered 10 each of 170 values 0.25w 1% metal film for like $19. Paid with paypal, got to my house in like 10 days from Hong Kong.Comment

Re: Counterfeit resistors
That works out about $25 NZ
At 1.8 cents per resistor I can buy 1700x 0.25w 1% metal film resistors from Farnell for $30.
$5 more but the shipping would be much faster, and the quality probably better.
The catch is you wouldn't get 170 values, as they have a MOQ of 50."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Counterfeit resistors
Thats the whole reason why I ordered from them to begin with... I'm getting into the tinkering thing and I need the widest range of resistors on hand that I can get my hands on with the tightest tolerance. I'm sure there will be many many values that I will never ever have any use for. But what I'm thinking is that a couple years down the line, who knows....I might just be needing that one oddball resistor value and hey I will have it! If that happens the price I paid for the entire assortment could easily pay for an entire order consisting of one resistor value from mouser or digikey.Comment

Re: Counterfeit resistors
Just watched them, pretty interesting. Pity we don't know what the result was for the 5% ones.Originally posted by mockingbird View Post
