RPM7237-H9R ROHM

RPM7237-R series Photo Link Module IR Receiver Module RPM7237-R series RPM7237-R series are remote control receiver module. Small-sized, light-weight, and low voltage operated (from 2.7V) modules have been achieved by using resin mold. z Center frequency 36.7kHz z Applications All household electric appliances such as TV, DVD, air conditioner and audio equipment. z Features 1) Low voltage operation. (VCC=2.7 to 3.6V) 2) Low current consumption. (ICC=0.3mA, VCC=3V) 3) Superior anti VCC noise characteristics. 4) 5 types of holders available to each set. z RPM7237-R series SIDE VIEW TOP VIEW Sub carrier frequency RSIP-A3 (H13) RSIP-A3 (H5) RSIP-A3 (H4) RSIP-A3 (H8) RSIP-A3 (H9) Height to lens 15.0mm 9.6mm 15.9mm 7.2mm 12.0mm RPM7237-H8R RPM7237-H9R 36.7kHz RPM7237-H13R RPM7237-H5R RPM7237-H4R Under development z Absolute maximum ratings (Ta = 25C) Parameter Symbol Limits Unit Supply Voltage VCC 6.3 V Output current IO 2.0 mA Storage temperature Tstg 30 to +100 C Operating temperature voltage Topr 10 to +75 C z Recommended operating conditions (Ta = 25C) Parameter Symbol Min.
