| NJL25V/28H000 INFRARED REMOTE CONTROL RECEIVER GENERAL DESCRIPTION NJL25V/28H000 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). NJL25V/28H000 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 0.56mA max. APPLICATIONS 1. AV instruments such as Audio, TV, VCR, CD, MD, DVD, STB etc. 2. Home application such as Air-conditioner, Fan etc. 3. Battery operated instruments such as Toy, Camera etc. LINE-UP View Type Height Side Top 15mm Carrier 15.6mm Frequency fo= 36 kHz NJL25V360 NJL28H360 36.7 kHz NJL25V367 NJL28H367 38 kHz NJL25V380 NJL28H380 40 kHz NJL25V400 NJL28H400 Regarding the other frequency or packages, please contact to New JRC individually.
