Specification Brand : Wisoqu BulletPoint1 : The ULN2803A device is a 50 V, 500 mA Darlington transistor array. BulletPoint2 : The device consists of eight NPN Darlington pairs, which have a high voltage output and a common cathode clamp diode for switching inductive loads. BulletPoint3 : The collector current rating of each Darlington pair is 500 mA. Darlington pairs can be connected in parallel to increase current capacity. BulletPoint4 : Applications include relay drivers, hammer drivers, lamps drivers, display drivers (LED and gas discharge), line drivers and logic buffers. BulletPoint5 : Each Darlington pair of ULN2803A devices has a 2.7kΩ series base and can work directly with TTL or 5V CMOS devices ExternallyAssignedProductIdentifier : 5601095793539 ItemName : 2Pcs ULN2803A Module, Voltage Driver Power Supply Module, Darlington Tube High Current Voltage Driver Electric Component ItemPackageDimensions_Height : 2 centimeters ItemPackageDimensions_Length : 8 centimeters ItemPackageDimensions_Width : 6 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : darlington-transistors Manufacturer : Wisoqu Material : Copper ModelName : Wisoquhnc1r23wpu ModelNumber : Wisoquhnc1r23wpu NumberOfItems : 2 PartNumber : Wisoquhnc1r23wpu ProductDescription : 1.
