Out of stockOSELTECH 3800 MAH RECHARGEABLE BATTERY ( PACK OF 2 PCS)
[Lithium Battery Cell] 3800 mAh 18650 3.7V Lithium-Ion Battery 18650 Li-ion battery is a lithium-ion rechargeable battery and is used in high drain applications due to its superior capacity and discharge rate. The first 4 digits of 18650 indicate its dimension, i.e. 18mmx65mm, and the last 5th digit indicates its shape, i.e. cylindrical. Li-ion batteries can usually boost a 300-500 charge cycle. Features : High energy density High working voltage for single battery cells. Pollution-free Long cycle life No memory effect Capacity, resistance, Voltage, platform time consistency is good. Good consistency and low self-discharge. Lightweight, small size Shape: Cylindrical Battery Battery Type: Lithium-Ion Battery High performance and capacity Flat top to suit many devices fitting. Weight 85gms Package Includes : 2 x Lithium-Ion 18650 Rechargeable Cell 3.7V 3800mAh
Out of stock74HC47 or 74LS47 IC BCD to seven segment decoder driver
[Logic Gates IC] 7447 or 74LS47 decodes BCD into 7 Segments, which means it accepts a binary coded decimal or BCD Values as input and decoded into a pattern that drives a 7-segment for displaying digits 0 to 9, so its name is BCD to 7 segment driver or decoder. Its input is 4 lines BCD data and generates complements as output. The generation of complement data of BCD is internally so no coding or programming is required to generate it. Specification Large Voltage range Has open collector output which directly drives indicator Has a wide range of operating conditions No need for external resistors because of internal pull-ups No high-speed termination because of the input clamp diode 4 the number of input lines and 7 output lines Pin Description BCD input 2 BCD input 3 LT RBO RBI BCD input 4 BCD input 1 GND E D C B A G F VCC
