What value is 42E2? 42.2 o k m

[stj]

Re: Resistor

42E = 2m67
maybe

because the last digit is not listed on my data - maybe the tolerance.

lookup E96 coding

Re: Resistor

I know the letter position marks decimal point EG 42.2 just not sure of ohm kohm or mohm

Re: Resistor

where did you get that info?

Re: Resistor

From one i did before i think they used that type of markings in italy and such

Re: Resistor

Resistors are identified on a circuit with numbers and letters to show the exact value of resistance - such as 1k 2k2 4M7
The letter W (omega - a Greek symbol) is used to identify the word "Ohm."
but this symbol is not available on some word-processors, so the letter "R" is used. The letter "E" is also sometimes used and both mean "Ohms."
A one-ohm resistor is written "1R" or "1E." It can also be written "1R0" or "1E0."
A resistor of one-tenth of an ohm is written "0R1" or "0E1." The letter takes the place of the decimal point.
10 ohms = 10R
100 ohms = 100R
1,000 ohms = 1k (k= kilo = one thousand)
10,000 ohms = 10k
100,000 ohms = 100k
1,000,000 ohms = 1M (M = MEG = one million)

Re: Resistor

SO i guess it is a 42.2 ohm

Re: Resistor

your playing a dangerous game making those assumptions.
i hope your right!

are there other resistors on your circuit with a letter code you could meter?

Re: Resistor

Yeah the ch2 i can measure when i open it back up

Re: Resistor

The last number is the power of 10. That would make it a 4.2 X 10^2 or 420 ohm resistor.

and the letter "E" ?

[ratdude747]

Re: Resistor

and the letter "E" ?

E for Exponential notation. Like the "E" key on a TI calculator.

Re: Resistor

they claim the E marks the decimal point

Re: Resistor

Can we see the pictures of this resistor?

[redlght]

Re: Resistor

There is one on each channel ill get a pic and measure the good one when i take it back apart

[redlght]

Re: Resistor



Good one reads 43 so 42.2 ohm it is

Re: Resistor

All these time I thought we are talking about SMD resistor with '42E2' marking on the top, it is through hole resistor with color band code.
So where did you get the '42E2' from?
Pictures are always important.

Re: Resistor


That is the value marked in the service manual schematic 42E2 rest are marked regular 10K and such.
42.2Ω 1%
Yellow, red, red, gold, brown.
Standard
1% (E96) value.
