Title
Standard Method of Test for Effective Series Resistance (ESR) and Capacitance of Multilayer Ceramic Capacitors at High Frequencies

Electronic Components, Assemblies & Materials Association

Publication Date:
Jan 1, 1981

Scope:

This method provides procedures for the measurement of effective series
resistance (esr) and capacitance of multilayer ceramic capacitors from
frequencies of 25 MHz to 1.25 GHz.  A series connection permits the
measurement of capacitance from below 1 pF to over 1 nF between
frequencies of 130 MHz and 1.25 GHz.  There is no maximum value of
capacitance for series measurements of esr, but the determination of
large values of capacitance at high frequencies suffers from inaccuracy.
The esr of capacitors can be measured with this method at frequencies
that exceed the self-resonant frequency of the test capacitor.  A shunt
connection allows the measurement of capacitance from 0 to 200 pF at
frequencies from 25 to 910 MHz.

           Resonant Mode     Frequency Range     Measurable Capacitance

Series Mode   lambda/4       130 to 250 MHz       greater than 1 nf to
                                                      less than 1 pF

             3lambda/4       390 to 500 MHz                "

             5lambda/4       650 to 750 MHz                "

             7lambda/4       910 to 1000 MHz               "

             9lambda/4      1170 to 1250 MHz               "

Shunt Mode    lambda/4        25 to 130 MHz         200 pF to 0 pF

             3lambda/4       265 to 390 MHz         100 pF to 0 pF

             5lambda/4       530 to 650 MHz          30 pF to 0 pF

             7lambda/4       785 to 910 MHz          30 pF to 0 pF

The limits shown for frequency and capacitance for shunt measurements
may be exceeded, provided the test specimen is not at or near its
self-resonant frequency, and the precautions of Section 6.0 are
observed.
