The 3625 series is used in similar
applications to the 3624 series,
however with a slightly different design
aimed at very low resistance to keep
power loss to a minimum. The 3625
series combines all the attributes of
Tyco Sigma inductors to give an
economically priced, high reliability
product suited to power line DC-DC
conversion applications and use within
a wide range of electronic equipment
applications.
