± 5% and ± 10% Resistors (P.N. 569-0105-xxx)

The three-digit number used to identify ±5% and ±10% resistors corresponds to the last three digits of the EFJohnson part number. This number is derived as follows. For example, “273” indicates a 27k ohm resistor and “339” indicates a 3.3 ohm resistor.

± 1% Resistors (P.N. 569-0111-xxx)

Some resistors with a ± 1% tolerance are identified by a four-digit number and others may not have a marking. When identified with a four-digit number, the first three digits are the value and the fourth is the multiplier. For example, “5761” indicates a 5.76k ohm resistor.

4.2.3 SMD CAPACITOR IDENTIFICATION

Ceramic SMD Capacitors (P.N. 510-36xx-xxx)

Ceramic SMD capacitors are identified using either an American or Japanese EIA standard. The American standard uses a single letter or number to indicate the value, and the color of this letter or number to indicate the multiplier. The Japanese standard uses a letter to indicate the value followed by a number to indicate the multiplier. The values for both standards are shown in the following table. For example, if there is a single black “E” on the capacitor, it uses the American standard and its value is 15 pF. The same value is identified with the Japanese standard by “E1”.

The Japanese standard may also utilize a bar to indicate the temperature coefficient. The following

coefficients are indicated by this bar. For example, “A2” indicates a 100 pF NPO capacitor.
