Ceramic Resistor Identification

Example of a wire wound resistor construction.

Ceramic resistor identification.

Resistors letters and digit codes. The colors on the first 2 or 3 bands correspond to numbers from 0 to 9 which represent the significant digits of the resistor s ohmic value. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Jameco sells ceramic resistors and more with a lifetime guarantee and same day shipping.

Browse our computer products electronic components electronic kits projects and more. The last band gives the multiplier. Method of finding the value meaning of codes of capacitor. The manufacturing and choice of materials used is dependent on the way the resistor will be used in.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Search is the most efficient way to navigate the engineering toolbox. Engineering toolbox resources tools and basic information for engineering and design of technical applications.

When the first two numbers are multiplied with the multiplier the. Then by just using numbers and letters as codes. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. In this video i have explained practically 1.

For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms. Letter and digit codes to indicating resistor values. A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to.

Wire wound resistor construction varies widely.
