0201WMF4703TEE是厚声(UNI-ROYAL)推出的0201封装厚膜贴片电阻,针对小型化、低功耗电子设备的信号调理、滤波等场景设计,兼顾成本与性能稳定性,是消费电子、工业控制等领域的常用基础元件。
采用0201英制贴片封装(对应公制尺寸约0.6mm×0.3mm×0.23mm),体积仅为常规0402封装的1/4,适合高密度PCB布局,可满足智能手机、可穿戴设备等小型化产品的“轻、薄、小”设计需求。
基于厚膜印刷工艺制造:以氧化铝陶瓷基片为载体,通过高精度丝网印刷厚膜电阻浆料(金属氧化物体系),经高温烧结形成电阻层,再覆盖环氧树脂涂层封装。该工艺兼顾了成本优势(比薄膜电阻低30%以上)与性能稳定性(比碳膜电阻抗温变能力强)。
两端电极采用镍/锡镀层(无铅环保),支持回流焊、波峰焊等常规贴片焊接工艺,焊接后电极附着力强,可避免虚焊、脱落等问题。
标称阻值470kΩ,精度**±1%**(即25℃基准温度下,实际阻值范围为465.3kΩ~474.7kΩ),满足大多数信号电路对阻值偏差的要求(如滤波电路截止频率偏差控制在±1%以内)。
±200ppm/℃:即温度每变化1℃,阻值变化约94Ω(470kΩ×200×10⁻⁶)。若环境温度波动在±20℃内,阻值总变化约±3.76kΩ,稳定性满足一般工业与消费电子场景需求。
支持**-55℃+155℃**的工作温度,覆盖工业级(-40+85℃)与部分高温场景(如汽车发动机舱附近的辅助电路),低温下无阻值漂移失效,高温下厚膜工艺的稳定性优于碳膜电阻。
环氧树脂涂层可抵御95%RH以下潮湿环境,避免电阻浆料受潮导致阻值漂移;额定条件下长期阻值漂移率≤0.5%/1000小时,满足批量设备的长期可靠性要求。
陶瓷基片具备一定刚性,可承受PCB轻微弯曲(≤0.5mm),适合对机械强度有要求的便携式设备。
厚声(UNI-ROYAL)是国内电阻行业龙头企业,成立于1996年,专注于被动元件研发生产,年产能超百亿只,产品覆盖全球30多个国家和地区。
通过ISO9001质量管理体系、IATF16949汽车电子认证、RoHS无铅环保认证,产品一致性与可靠性符合国际标准。
支持大规模OEM/ODM订单,交货周期稳定(常规订单7~10天),适合电子制造企业的量产需求。
0201WMF4703TEE以小巧体积、稳定性能、宽温适应性为核心优势,平衡了成本与性能,是电子设计中应对小信号电路需求的优选元件,可广泛应用于消费电子、工业控制等多领域。

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.
