【产品】可抗10kA浪涌的气体放电管(GDT),平坦响应最高可达10kV/μs
LITTELFUSE是电路保护领域的全球领先企业,可提供种类最多、范围最广的电路保护产品组合。SL1122A系列气体放电管(GDT)由Littelfuse出品,已通过无铅认证,是一种高性能的Alpha气体等离子体管与MOV的结合品,它们相互配合,高速脉冲可首先被MOV箝位,然后当电流上升,瞬态能量就会通过气体放电管导出。SL1122A系列气体放电管在处理100V/µs到10kV/µs的快速上升的瞬态电压中具有突出表现,可安全地保证器件在最高为10000A的脉冲中免受破坏。SL1122A系列气体放电管非常适用于MDF保护、ADSL设备、XDSL设备、警报控制盘和通用电信设备等领域。
SL1122A系列气体放电管具有SL1122A090、SL1122A230、SL1122A260三个型号,它们的直流击穿电压典型值分别为90V、230V和260V(100V/s条件下),可分别安全地适用于不同电压环境中。三款气体放电管的绝缘电阻均大于108Ω,绝缘性能极好,对环境湿度不敏感;另外,该系列气体放电管的等效电容最低仅为100pF,在保护电路的同时,最大限度的降低了对通信信号的干扰。最高可抗10kA的浪涌电流,具有超强的抗浪涌能力。
SL1122A系列气体放电管的工作和储存温度范围为-40~90℃,能够满足绝大部分工业应用场合的温度要求。另外,其电极基座采用铜材质,电极光亮镀锡,可焊性好,焊点牢固,导电率高。管体采用陶瓷材料,坚固可靠,热传导性能好。
