SMD4532-090NB 是 BORN(伯恩半导体)推出的一款表面贴装气体放电管(GDT),采用 SMD 封装,外形尺寸 4.5 × 3.2 mm,器件高度 2.7 mm,双端(2端)结构。该器件专为防护通信接口、以太网、PoE 供电线路及其它需承受高能脉冲的电源/信号线路而设计,具备大能量浪涌吸收能力与极低对信号线的干扰(低极间电容),适合自动化贴片组装与紧凑电路板布局。
气体放电管属于低漏电、高能量吸收件;多次强冲击后可能需要检查或更换。建议对关键保护点进行浪涌事件后的功能验证。存储与使用期间避免超出器件额定电压和温度范围,以延长使用寿命和稳定性。
SMD4532-090NB 是一款面向高能浪涌防护的紧凑型 SMD 气体放电管,凭借 2 kA 的脉冲放电能力、90 V 的直流触发电压与 0.8 pF 的低极间电容,适合在通讯、工业与电源系统中为敏感线路提供可靠的过压保护。设计时应结合系统浪涌水平、信号完整性需求及 PCB 布局,必要时与 TVS 等器件配合使用以实现最优的防护效果。如需精确的焊接温度曲线、寿命试验数据与典型波形响应,请参考 BORN 官方数据手册或联系供应商获取完整资料。

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.
