DERATING CURVE |
 |
|
Temperature rise at 20°C ambient
for 100W-400W is 275°C plus ambient Wattage can be increased by
using heatsink. Above 275°C derating is required
Ordering PROCEDURE
Ex. SLRN500 100R K 1005 where N
indicates non-inductive, R indicates ohms, K indicates 10% tolerance
which may change, 1005 indicates month & year of manufacture. |
