Low Ohms
Feature
•Under
1 ohms, precision resistance.
•Both
flow and reflow soldering are applicable.
•Owing
to the reduced lead inductance, the high frequency
characteristic is excellent.
The product of lead-free terminal is RoHS compliant.
PhO(lead oxide) is included in the glass of our product which is prescribed
on RoHS appendix as an exception.
Application
•Current
detect.
•Safe
circuit through protecting over-current flow.
•Power
supplying part.
•Motor
controlling, DC power charger, etc.
