APACITORS
Johanson switch-mode ceramic capacitors feature large capacitance
values and exhibit low ESR (equivalent series resistance) and low
ESL (equivalent series inductance) making them well suited for
high power and high frequency applications where tantalum or alu-
minum electrolytic capacitors may not be suitable.

The left-hand portion of the curves represents the capaci-
tive reactance of two typical values. The impedance
decreases until series resonance is reached. At this point
(the bottom of the V), the only component of the imped-
ance is the ESR. At higher frequencies (the inductive
portion) the ESR remains relatively low so that effective
filtering is maintained.

These curves reflect the very low ESR of two typical
values. These ESRs are much lower than Tantalums or
Aluminum electrolytics of the same values. The result is
the ability to provide filtering (low loss) and to handle
high power requirements.

RECAUTIONS
The large ceramic mass of switch mode capacitors increases their susceptibility to damage from thermal shock during
soldering. Parts should be pre-heated to within 50°C of the peak soldering temperature and the pre-heating cycle’s
thermal gradient should be limited to a maximum of 2°C per second.
