These CR25 high-stability carbon film resistors are suitable for all types of industrial and consumer applications and have a +/- tolerance of 5%. The resistive element is a high-grade ceramic rod on which a homogenous pure carbon film is deposited by a vacuum heating process to produce electrical conductivity on the surface. All available resistors are in EIA standard colour coding and resistant to solvents.

The resistors are supplied taped together and then rolled. The resistors are spaced 5mm apart on the roll and can easily be removed from the roll by tearing the tape to separate the appropriate quantity and then pulling away the tape.

See the list on the right for the available versions.  A zero-Ohm resistor is also available, which is a useful alternative to jumper or wire links on PCBs. All versions are supplied as a pack of 100, which offers excellent value.

Features:

  • All varieties are CR25 0.25W carbon film resistors.
  • Colour bands are EIA standard colour coding.
  • The tolerance is +/- 5%.
  • They are taped and rolled with a 5mm spacing.
  • They are supplied as packs of 100, offering great value.
  • RoHS compliant.

Contains:

  • 1 x 100 Packs Of CR25 0.25W Carbon Film Resistors.

Dimensions:

  • Body Length: 6.5mm.
  • Body Diameter: 2.5mm.
  • Lead Length: 28mm.
  • Lead Diameter: 0.6mm.

    Asked by suc ur marge on June 5, 2019 12:00 am
    Answered by the admin Good Afternoon,

    Thank you for your question, the resistors are for protecting circuits from excess voltage being put through them. For example if you put 9V into a 3V LED you would damage it so resistors can protect against such.

    Asked by Mark Holloway on March 1, 2019 12:00 am
    Answered by the admin Hi Mark,

    Thank you for your question, it would be 3003-47K

    Answered by the admin Hi Jordan, The resistor pack of 100 isn't 100 different resistors, it is however a pack of 100 of a particular valued resistor. We do have a 6.8K version, it is code 3003-6K8.
  6. So just to confirm your calculator gives me a result of 150ohms, so I need a resistor 3003-150r is this right

    Asked by Susan nice on December 4, 2017 12:00 am
    Answered by the admin Hi Susan, I'm not too sure why you have been given a value that high if you are using just 3V as a power supply. It also appears my previous answer is slightly wrong as the incorrect information was pulled through. With the 35103 LED you wouldn't require a resistor if powering from a 3V LED.

    Q what Is the difference between r and k on ordering resistors
    Asked by steven page on June 15, 2016 12:00 am
    Answered by the admin The R and K are used to help identify the value of the resistor. Resistance is measure in Ohm, but if you were to put that after the number it could be confused for a different value as it could be mistaken for a zero. The K refers to Kiloohms, so a resistor marked as 3003-1K, would have a value of 1KOhm or 1000 Ohm’s. The R is used when the resistor value is less than a Kiloohm, for example 3003-10R is a 10 Ohm resistor. When the R falls between numbers for example 3003-4R7 it would have a value of 4.7 Ohm’s.
