聚合物ESD抑制器

聚合物ESD抑制器

静电放电(ESD)是一种电子交易nsient that poses a serious threat to electronic circuits. The most common cause is friction between two dissimilar materials, causing a buildup of electric charges on their surfaces. Typically, one of the surfaces is the human body, and it is not uncommon for this static charge to reach a potential as high as 15,000 volts. At 6,000 static volts, an ESD event will be painful to a person. Lower voltage discharges may go unnoticed, but can still cause catastrophic damage to electronic components and circuit.

用于波多接线设备的Littelfuse植物是ISO / TS 16949:2009和ISO 9001:2008认证。

Pulse-Guard®ESD抑制器

Littelfuse PulseGuard®ESD抑制提供extremely low capacitance which makes them ideal for use in high-speed data circuits (IEEE 1394, USB 2.0, HDMI, DVI, etc.). Available in single-line and multi-line packages, they provide ESD protection while ensuring that signal integrity is maintained.

何时选择Pulse-Guard®ESD抑制器与其他ESD保护技术:

  • The application tolerates very little added capacitance (high speed data lines or RF circuits)
  • ESD is the only transient threat
  • 数据,信号和控制线(不是电源线)需要保护

XTREME-GUARD™ ESD Suppressors

Xtreme-Guard™ESD抑制器在非常小的0402和0603占地面积中保护敏感的电子设备免受极端的ESD条件。该系列产品专门设计用于抑制高达30kV的快速上升的ESD瞬变,同时为电路添加几乎没有电容,这有助于保持信号完整性并最小化数据丢失。它被设计为符合RoHS,无卤素和PB免费。

Why choose XTREME-GUARD™ ESD Suppressors versus other ESD suppression technologies:

  • XGD系列Xtreme-Guard™ESD抑制器可保护敏感电子器件免受静电放电,高达30kV,适用于高达32VDC的高压应用
  • When correctly integrated into a circuit design, the XGD Series can safely absorb repetitive ESD strikes nearly four times the maximum level specified in the IEC61000-4-2 international standard without performance degradation
  • 即使在多次ESD击球后,它也表现出超低电流泄漏(<1NA),确保最小的功率损耗,因此它非常适合保护电池供电的电子产品如可穿戴物品
