Part No. 001-9800-001
± 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 stan-
dard 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 stan-
dard 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.
XX = NPO XX = N150 XX = N220
XX = N330 XX = N470 XX = N750
|XX = X7R
