WS7872DE-6/TR 是韦尔(WILLSEMI)推出的一款高性能单刀双掷(SPDT)射频开关,覆盖宽频带从 100MHz 到 7.125GHz,适用于手机、无线通信、蓝牙/Wi‑Fi、物联网及多天线射频前端场景。器件以紧凑封装 DFN-6-EP (1×1 mm) 提供,便于在小型化设计中实现开关功能。
WS7872DE-6/TR 设计适用于工业级温度范围(-40 ℃ ~ +85 ℃),适合常见移动与工业应用的环境要求。为确保长期可靠性,建议在极端高温或高湿环境中做功率与热评估,并遵循厂商关于焊接工艺与回流曲线的建议。
封装为 DFN-6-EP(1×1 mm),适合高密度布局。选型时应关注系统频段、插入损耗容忍度与隔离要求,若系统涉及更高频率或更低损耗需求,可与其他型号或更高等级的射频开关比较后再定型。购买与生产中建议向韦尔或授权代理索取器件数据手册(Datasheet)与应用笔记,以获取完整引脚定义、典型性能曲线和封装焊盘尺寸图,便于 PCB 布局与信号完整性验证。

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.
