Model
6" X 4" X 2" X .040" aluminum chassis, MP312 free air rating is
2.5 Watts at 25°C. MP330 30 Watt power rating based on
chassis mounting on a 7"X 5" X 2" X .040" aluminum chassis,
MP330 free air rating is 5.0 Watts at 25°C.
Two case sizes that provide 15 Watt and 30 Watt ratings.
Operation up to 275°C.
Single screw mounting to simplify attachment to the chassis or other heat
conducting surface.
A molded silicone case that encapsulates the resistor assembly to meet
stringent environmental specifications.
Extended life stability better than 0.01% per 1,000 hours has been
demonstrated through a 5
load life testing.

Data is for 25°C air at 1 atmosphere,
ducted around resistors in the stack
with 2" x 2" x .04" aluminum plates
between resistors. To derive total
airflow required for stack, multiply
airflow/each resistor by the number
of resistors in the stack. Ducting is
not required when designing for
convection.
