led數(shù)碼管顯示屏產(chǎn)品說明書型號(PART NO.): ZB2718BW
1. led數(shù)碼管顯示屏說明(Description):
發(fā)光顏色(Emitted Color):白光
外觀顏色(Lens Color):黑、白兩色
外形尺寸(Max Size):如結構尺寸圖所示
極限參數(shù)(Absolute Maximum Ratings) 建議使用驅(qū)動檢測
參數(shù)(Parameter) | 單位 (Symbol) | 極限值 (Maximum Rating) | 單位(Unit) |
功耗 (Power Dissipation) | Pd | 42 | mW |
脈沖電流(Peak Forward Current) | Ifp | 100 | mA |
直流電流(Continuous Forward Current) | Ifm | 20 | mA |
反向電壓(Reverse Voltage) | VR | 5 | V |
工作溫度(Operating Temperature Range) | Topr | -40 → +85 | ℃ |
儲藏溫度(Storage Temperature Range) | Tstg | -40 → +100 | ℃ |
靜電電壓(Static Voltage) | Var | V |
*焊接溫度(Lead Sodering Temperature):260℃ for 3 seconds
*當工作溫度高于 25℃時,Ifm,Ifp 和 Id 必須降低;電流降低率是-0.36mA/℃(直流驅(qū)動),或-0.86mA/℃
(脈沖驅(qū)動)功耗降低率是-0.75mW/℃。產(chǎn)品的工作電流不能大于對應工作溫度條件 Ifm 或 Ifp 的 60%。For operation above 25℃, The Ifm Ifp & Pd must be derated, the Curent derating is –0.36mA/℃ for DC drive and -0.86mA/℃ for Pulse drive, the power dissipation is -0.75mW/℃. The product working current must not more than the 60% of the Ifm or Ifp according to the working temperature.
