| 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 0.43mA typ. Vcc=3.3V APPLICATIONS 1. AV instruments such as Audio, TV, VCR, CD, MD, DVD, STB etc. 2. Home application such as Air-conditioner, Fan etc. 3. Game machine, toy etc. LINE-UP View Type Height Carrier Frequency fo= 36 kHz 36.7 kHz 38 kHz 40 kHz Side 15.6mm NJL25V360 NJL25V367 NJL25V380 NJL25V400 Top 15mm NJL28H360 NJL28H367 NJL28H380 NJL28H400 Regarding the other frequency or packages, please contact to New JRC individually.
