LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Notes
1. When operating at V
P
> 16 V, the output power must be limited to 85 W at THD = 10% (or minimum load is 6
Ω
).
2. T
j
is a theoretical temperature which is based on a simplified representation of the thermal behaviour of the device.
T
j
= T
c
+ P
×
R
th(j-c)
, where R
th(j-c)
is a fixed value to be used for the calculation of T
j
. The rating for T
j
limits the
allowable combinations of power dissipation P and case temperature T
c
(in accordance with IEC 60747-1).
