RPM6900 series
RPM6900 series are remote con trol receiver modules. Small-siz ed and light-weight modules hav e been achieved by
using resin mold.
zApplications
All household electric appliances su ch as TV, DVD, air conditioner and audio equ ipment.
zFeatures
1) Good EMI noise shielding characteristics.
2) Excellent sun light noise shielding performance.
3) Built-in electric-magnetic shield no requiring shield-casing.
