Table 1 SIP resistor values and the corresponding 3 dB points of the frequency dividing network and EQ
center frequencies.
Resistor values given in ohms (Ω).
Frequencies given in hertz (Hz).
The resistor values are usually coded with three numbers on the SIP housing. The two most
significant digits represent the resistor value. The third number determines the magnitude by
defining the number of zeroes that must be attached to number one and two.
Examples: 222: 2200 Ω = 2,2 kΩ
153: 15000 Ω = 15 kΩ
