SMD4532-400M(品牌:DOWO/东沃)是一款面向中高压瞬态抑制与浪涌保护的片式二端器件,封装为1812(尺寸 4.5 × 3.2 × 2.7 mm)。器件极数为双极(2 极),直流击穿电压标称 400 V,精度 ±20%,脉冲放电能力高达 2 kA,极间电容仅 1 pF,工作温度范围 -40 ℃ 至 +90 ℃。总体定位为在高压供电与防雷/浪涌抑制场合提供可靠的过压保护,同时对高速信号线影响极小。
注:具体应用时请参考厂方完整数据手册以确认测试条件(如脉冲波形、测量标准等)。
DOWO(东沃)对出厂器件通常进行基本电气参数测试与外观检验,支持样品测试与批量供货。建议在量产前与供应商确认详细的可靠性测试报告、浪涌试验条件(如 8/20 µs 或其他波形)以及环保与放行文件(如 RoHS 等),以满足项目的认证和质量要求。
如需进一步的原理图接入示例、推荐封装焊盘尺寸或实际波形下的能量吸收曲线,可联系供应商获取完整数据手册与实验测试资料。

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.
