DC/DC Converter TED Series Features Full SMD design with Ceramic Capacitors Wide 2:1 Input range High Efficiency Short Circuit Protection Dual Output Models with galvanic isolated Outputs Metal Case, 24–Pin DIP 2 Year Product Warranty 2 Watt The TED-series are high performance, isolated DC/DC-converters with wide 2 :1 input range. They are ideally suited for distributed power systems in telecommunications, industrial electronics and test equipment. Full SMT-design with exclusive use of ceramic chip-capacitors guarantees very high reliability with a calculated MTBF of over 1Mil.h. A highly automated production with 100% parameter test of each converter ensures the high quality standard of this product.
