The L vaule at 0A is higher than the guaranteed performance. Operating temperature range: 40 to +105C (Including self-temperature rise) Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
