The difference between CXA-0349 and CXA-0547.
*Product summary
CXA-0547 expands operating temperature range to -20ºC~70ºC compared with CXA-0349.
At the same time, all components is mounted by machine. So human error reduces and reliability is
improved.
Input fuse rating is changed because the lamp impedance at low temperature is high.
This product is expected stable supply to the customer by replacement of terminated components.
