2R090SB-8 是 RUILON(瑞隆源)推出的一款 SMD 型号气体放电管(GDT),面向需要大能量冲击保护且对线路电容敏感的应用场景。该器件为双极(两端)结构,额定直流击穿电压 90V、脉冲放电能力高达 10kA,直流与冲击耐压、低极间电容、小尺寸封装等特性,使其在通信、以太网/PoE、安防与工业接口等场合具有明显优势。
2R090SB-8 为表面贴装式气体放电管,外观小巧(8×6mm),便于在 PCB 上靠近接口或设备入线端放置,以缩短流向接地的回路长度。因其为双端器件,通常以两端直接连接被保护线路与参考地或对称线路上。封装材料与焊盘布局应遵循制造商推荐,以保证可靠焊接与散热。
总结:2R090SB-8 以其 90V 的直流击穿等级、10kA 的瞬态放电能力和极低的极间电容,适合对带宽与抗浪涌能力同时有要求的保护场合。合理的 PCB 布局与多级保护设计能发挥其最佳防护效果;在实际应用中,请参考瑞隆源提供的完整数据手册与测试条件以获得准确的设计依据。

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.
