Electronic parts made by Sakatsu, non-scale LED Standard Chip size 2.0mm x 1.6mm (thickness is approx. 1.5mm including lead wires) Appropriate voltage: 3V Appropriate current: 10mA DC only Lead wire: approx. 23 cm long, red pin is positive, black is negative Note: Specifications are subject to change without notice. Features Compared to light bulbs, LEDs are "power-saving," "long-lasting," and generate almost no heat, making them ideal for integration into models! The size of the chip is larger than the conventional 1.6 x 0.8mm and the light is much brighter than the conventional 1.6 x 0.8mm. The LEDs come with pins, so they can be used in combination with the Sakatsu LED system (dimming power supply for LEDs, basic circuit board, etc.) without soldering!
