0201WMJ0472TEE 是 UNI-ROYAL(厚声)系列厚膜贴片电阻中的超小型通用型号,标称阻值 4.7kΩ,精度 ±5%,额定功率 50mW,额定工作电压 25V,温度系数 ±200ppm/℃,工作温度范围 -55℃~+155℃。该器件以 0201 超小封装为主,适合高密度、多层板的微型电子产品设计。
适用于便携式消费电子、无线通信模块、物联网终端、数模混合电路中的上拉/下拉、电阻分压、限流、偏置与阻尼网络等对阻值精度要求不高但空间受限的场合。
0201(常见外形约 0.6mm × 0.3mm)为业界超小封装,实际尺寸与焊盘推荐应以厂方尺寸图为准。因体积极小,贴装与检测对工艺与设备要求较高,建议使用适配 0201 的印刷模板、贴片机和 AOI 检测方案。
总结:0201WMJ0472TEE 以其超小封装和稳定的厚膜工艺,适合空间受限且对阻值精度要求不高的通用电子应用。设计时应充分考虑功率余量、散热及贴装工艺,以保证长期可靠性。若需替代或批量应用,可与供应商确认更详细的机械图、电气老化数据和回流曲线。

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.
