4 Thermal Curve o o The operating case temperature range of MHB-100 series is -40 C to +100 C. When operate the MHB-100 series, proper de-rating or cooling is needed. o The maximum case temperature under any operating condition should not be exceed 100 C. The following curve is the de-rating curve of MHB-100 series without heat sink.
