| NJL35V/38H000 INFRARED REMOTE CONTROL RECEIVER GENERAL DESCRIPTION NJL35V/38H000 series are small and high performance receiving devices for infrared remote control system. They can operate under low and wide supply voltage (2.7V to 5.5V). NJL35V/38H000 series are mesh window type to improve EMI characteristic. Even under strong EMI noise condition such as TV, Air-conditioner, etc., NJL25V/28H000 series can work normally. FEATURES 1. Wide and low supply voltage 2. Low supply current 3. Metal case type with mesh window 4. Line-up for various center carrier frequencies 2.7V to 5.5V 0.43mA typ. Vcc=3.3V APPLICATIONS 1. Home application such as Room light Air-conditioner, etc. 2. AV instruments such as Audio, TV, DVD, STB etc. LINE-UP View Type Height Side Top 15mm Carrier 15.6mm Frequency fo= 36 kHz NJL35V360 NJL38H360 36.7 kHz NJL35V367 NJL38H367 38 kHz NJL35V380 NJL38H380 40 kHz NJL35V400 NJL38H400 Regarding the other frequency or packages, please contact to New JRC individually.
