MVR1206-470G 是东沃(DOWO)推出的一款1206封装压敏电阻(多层抑制器),用于低压直流/交流系统的浪涌与过压保护。其标称压敏电压为47V,钳位电压为77V,适合在工作电压不超过36V DC(或28V AC RMS)的场合作为瞬态过压防护元件。器件封装为常见的1206 尺寸,便于表面贴装生产。
注:850pF 在1MHz 时的容抗约为 1/(2π·1MHz·850pF) ≈ 187Ω;在更高频率下容抗迅速下降,会对高速数据信号造成明显负载,应在设计中予以考虑。
如需更详细的电气特性曲线(V–I 曲线、钳位与漏电随温度的变化、浪涌波形下的钳位电压)、封装尺寸图或推荐的 PCB 布局示意图,可向东沃或授权代理索取完整数据手册与应用说明。

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.
