Description

These OM7640SM are supplied in a hermetic metal surface mount package. All protective features are designed into the circuit including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.5 amps of output current. These units feature internally trimmed output voltages to ±1% of nominal output voltage. Standard voltages are 5V, 12V, and 15V. These OM7640SMs are ideally suited for Military applications where a hermetically sealed surface mount package is required.
