KESD5311N 是 KUU 推出的一款聚合物静电放电(ESD)抑制器,面向对信号完整性要求高的高速接口与敏感电子模块。该器件为单路、双向保护结构,额定反向截止电压(Vrwm)为 5V,具有极低的结电容(输入/输出至地:0.05 pF),在不影响高速数据传输的前提下,为器件提供可靠的静电防护能力。器件采用 0402 超小封装,适合集成在空间受限的移动、消费类及工业电子产品中。
(注:上述电气项为器件典型或关键规格,实际应用中应参考器件具体数据手册以获得详细的特性曲线和测试条件。)
KESD5311N 采用 0402 封装,具有体积小、寄生电感电容极低的优势。超小封装便于在接口附近就近布置,减少走线长度和回路面积,从而提升 ESD 抑制效果并减少对高频信号造成的影响。0402 尺寸也利于自动化贴装与批量生产。
KESD5311N 基于聚合物 ESD 技术,具备自恢复性、低漏电和高重复防护能力。该器件被设计用于通过 IEC 61000-4-2 等级 4 的测试要求(示例:15 kV 空气放电、8 kV 接触放电),适合需要严格静电防护的产品开发。器件的工作温度范围 -55 ℃ 至 +125 ℃,适应宽温环境应用。
KESD5311N 凭借超低结电容与小体积封装,为要求高信号完整性同时需满足严苛静电防护的设计提供了理想选择。若需进一步的电气特性曲线、封装图或推荐 PCB 尺寸布局,请参阅 KUU 官方资料或联系供应商获取完整技术支持。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
