The RPM7237-R series is a remote control receiver module. Small-sized, light-weight, and low voltage operated (from 2.7V) modules have been achieved by using resin mold.
The RPM7237-H4R is a small‑sized, low‑voltage infrared receiver module intended for household electric appliances such as TVs, DVD players, air conditioners and audio equipment. It operates at a center frequency of 36.7 kHz and offers low current consumption (0.3 mA) with superior anti‑Vcc noise characteristics.
