RPM6938-V4 ROHM

IR Receiver Module RPM6900 Series Data Sheet RPM6900 series are remote control receiver modules. Small-sized and light-weight modules have been achieved by using resin mold. Applications All household electric appliances such as TV, DVD, air conditioner and audio equipment. Features 1) Good EMI noise shielding characteristics. 2) Excellent sun light noise shielding performance. 3) Built-in electric-magnetic shield no requiring shield-casing.
