CSA: Established in 1919, the Canadian
Standards Association is an independent
organization that sets safety standards
(and tests for compliance)
for electronic components
and systems that are to be
sold in Canada. See IEC,
UL, TUV and VDE.
Capacitance: An electrical property that opposes
a change in voltage level and stores energy in an
electrostatic fi eld.
Capacitive Coupling: The coupling of a signal
between two circuits or components caused by
discrete or parasitic capacitance.
Capacitive Input Filter: A fi lter that uses a capacitor
as its input component. See Input Line Filter,
Choke Input Filter, Common Mode Filter, Pi
Filter and Output Filter.
Case: See Enclosure.
Case Temperature: When the power supply and
surrounding system are operating normally, the
temperature of the unit case. Often used as a specifi
cation (as opposed to ambient temperature) for
power supplies with extended temperature ranges
or high power densities. Case temperature is sometimes
referred to as Baseplate Temperature.
