0.25 Watt Carbon Resitor Values

[RodneyB]

Please could someone Kidly direct me to Where I can get a complete list of 0.25 Watt carbon Resistors as industry standards. I am trying to do a stock list of resistors and generate a data base and I would like to set it up with all available carbon 0.25 Watt resistors even if I dont have them.



Here in Zimbabwe we have no Change so when we buy components we get resistors at our local electronic shop as change so I would like to make a full list and then get resistors I dont have this will help me build up my range of resistors

Hi,

What tolerance do you want?

EIA STANDARD RESISTOR VALUES
These values under 100 Ohms are meant to show the significant digits. All resistors
would have these values multiplied by the appropriate power of 10. For example, a
1% resistor could be 10.2 Ohms, 102 Ohms, 1020 Ohms, 10200 Ohms, and so forth.

If you're talking about carbon film having 5% tolerance, then have a look at the E24 series.

https://en.wikipedia.org/wiki/Preferred_number

https://www.logwell.com/tech/components/resistor_values.html

 

[audioguru]

I used E24 series values for all of my 40 years career and still do.
I have never used 1% and some of the 5% resistors that I bought actually were 2%.

 

[RodneyB]

I am looking for a list of all the resistors in the 10% tollerance 0.25 Watt range

 

[audioguru]

I haven't seen a 10% resistor for sale since about 1965. 5% is very common.
