Additional Infomation About Product

DC/DC Converter TMR 3E Series, 3 Watt Wide 2:1 input voltage range Compact SIP-8 package Cost optimized design Temperature range 40C to +85C I/O isolation 1500 VDC UL 62368-1 IEC 62368-1 Remote On/Off control The TMR 3E series is a family of isolated 3 W DC/DC converter modules with regulated output, featuring wide 2:1 input voltage ranges. The product comes 3-year product warranty in a compact SIP-8 plastic package with small footprint occupying only 2.0 cm (0.3 square inch) of board space. An excellent efficiency allows 40C to +85C operation temperature. Further features include remote On/Off control and continuous short circuit protection. The compact dimensions and cost opti- mized design make this converters an ideal solution for applications in commu- nication equipment, instrumentation and industrial electronics.
