Feature:1. The kit contains 175 small photo resistors, 7 different types, can meet different requirements.2. With a separate storage box, different types of photoresistors can be stored for easy use and carrying3. Photoresistor is the resistance of semiconductor material, and the conductivity will change with the change of light intensity.4. Stable performance, can be widely used in toys, lights, cameras and other industries.5. DIY electronic components, quick response, high sensitivity and good spectrum characteristics.Specification:Condition: 100% Brand NewItem Type: Photosensitive ResistorMaterial: Deposited FilmModel: GL5506 GL5516 GL5526 GL5528 GL5537 GL5539 GL5549DC Maximum Watt: 100mWWorking Temperature: -30 - 70Spectrum Peak: 540nmBright Resistance (10 Lx) (K): GL5506: 2-5, GL5516: 5-10, GL5526 GL5528: 8-20, GL5537: 18-50, GL5539: 30-90, GL5549: 45-200Dark Resistance: 1 M10010: GL5506-0.2 GL5516-0.6 GL5528-0.8 GL5537-0.7 GL5539-0.9 GL5549-0.9Response Time: 20ms (Rise), 30ms (Fall).Package List:25 x GL5506 Photosensitive Resistor25 x GL5516 Photosensitive Resistor25 x GL5526 Photosensitive Resistor25 x GL5528 Photosensitive Resistor25 x GL5537 Photosensitive Resistor25 x GL5539 Photosensitive Resistor25 x GL5549 Photosensitive Resistor
