0201WMF1073TEE是UNI-ROYAL(厚声) 推出的一款小体积精密厚膜贴片电阻,针对高密度PCB设计、低功耗电路场景优化,兼顾精度、稳定性与成本优势,广泛适配工业控制、消费电子、便携式设备等领域。
该型号属于厚膜贴片电阻系列,采用0201封装(英制尺寸:0.02英寸×0.01英寸,公制约0.6mm×0.3mm),是当前贴片电阻中体积最小的规格之一,核心定位为低功耗场景下的精密分压/限流元件。标称阻值107kΩ(标识代码1073),精度±1%,满足对阻值误差敏感的电路设计需求,避免批量生产中的参数离散性问题。
标称阻值为107kΩ,精度等级±1%,属于工业级精密电阻范畴(优于常规±5%、±10%通用电阻)。该精度可确保电路中分压比、限流值的一致性,例如在传感器信号调理电路中,能稳定输出精准的电压/电流信号。
0201封装体积紧凑,适合高密度PCB设计(如智能手机主板、小型基站模块),可显著减少电路占板面积(比0402封装小约70%);同时兼容常规回流焊工艺,焊接兼容性好,适合自动化批量生产,降低组装成本。
采用厚膜印刷工艺,电阻膜附着力强、一致性好,长期使用阻值稳定性高;相比薄膜电阻,成本更具优势,同时耐脉冲性能(如瞬态电压冲击)优于部分薄膜产品,适合对成本敏感但需一定稳定性的场景(如消费电子批量生产)。
该型号因体积小、精度高、宽温适配,广泛应用于以下场景:
在工作温度范围内(-55℃~+155℃),阻值最大漂移约为4.5kΩ((107kΩ×200ppm/℃×210℃));若应用于室内环境(温度波动±20℃),漂移仅约0.43kΩ,满足多数电路的性能要求。
符合IEC 61000等工业标准,耐湿、耐温循环性能优异,可适应湿度变化大(如90%RH)、温度波动频繁的场景;长期老化测试显示,1000小时后阻值变化率小于0.5%,可靠性满足量产产品要求。
总结:0201WMF1073TEE厚膜贴片电阻以小体积、精密精度、宽温适配为核心优势,兼顾成本与可靠性,是低功耗精密电路设计的优选元件。
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.
