SMT Power Inductors

DS3316P Series
Magnetic shielding and high efficiency are features of
the DS3316 family of power inductors. They are de-
signed for high performance DC-DC converter applica-
tions, especially those requiring shielding.
The terminations wrap around the end of the base,
ensuring a sound solder fillet and simplifying inspection.
Saturation current ratings up to 11 A and rms current
ratings as high as 5 A are available. DC resistance as
low as 0.021 Ohms keeps power losses to a minimum.
For new designs, consider the MSS1038 as an alter-
native to this series. The MSS1038 series is more cost
effective, features a smaller footprint, lower profile, lower
DCR and better current handling. We will continue to
manufacture and support the DS3316 indefinitely.
