0201WMF4704TEE是UNI-ROYAL(厚声) 推出的一款厚膜贴片电阻,型号命名对应明确参数:
该产品定位为小体积高精度通用电阻,适配高密度贴装与宽温环境下的信号电路。
阻值标称4.7MΩ,精度±1%——实际阻值范围为4.653MΩ~4.747MΩ,无需额外校准即可满足工业、消费电子对信号电路的精度要求(如传感器接口、运算放大器偏置)。
温度系数**±200ppm/℃**——每变化1℃,阻值相对变化百万分之200。以工作温度范围(-55℃~+155℃)计算,温度变化最大210℃,阻值最大波动为±4.2%(结合±1%精度,总波动范围约±5.2%),可满足工业级设备对宽温稳定性的基本需求。
-55℃~+155℃覆盖了:
无需额外散热或温度补偿,可长期稳定工作。
0201封装体积极小(约0.6mm×0.3mm×0.23mm),适配手机、智能手环等高密度PCB设计;厚膜工艺使电阻具有较好的抗脉冲能力(比薄膜电阻高2~3倍),可承受短暂过压/过流冲击(如电路瞬态尖峰),降低失效风险。
厚声采用成熟的厚膜印刷+烧结工艺,电阻膜层均匀性好:
UNI-ROYAL(厚声)作为国内电阻行业龙头,0201WMF4704TEE具有以下优势:
注意:该产品未标注汽车级认证(AEC-Q200),若用于车载场景需确认厚声汽车级衍生型号。
综上,0201WMF4704TEE是一款性价比突出的小体积高精度厚膜电阻,适合对尺寸、精度、宽温有要求的通用信号电路设计。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
