0201WMF7502TEE 厚膜贴片电阻产品概述

一、产品基本定位与核心标识

0201WMF7502TEE是UNI-ROYAL(厚声)推出的厚膜贴片电阻,型号编码直接映射核心参数:“0201”为封装规格,“7502”代表标称阻值75kΩ(75×10²Ω),“±1%”为精度等级,“1/20W”即额定功率50mW。该产品定位于低功耗、小体积、中等精度的电子电路场景,适配消费电子、工业控制等领域的小型化设计需求,是高密度PCB板的常用基础元件。

二、关键电气性能参数

该电阻的核心电气指标经过严格标定,可满足多数电路的稳定工作需求:

  1. 阻值与精度:标称阻值75kΩ,精度±1%——无需额外校准即可支撑反馈、分压、限流等功能,覆盖从低功耗信号调理到基础工业控制的精度要求;
  2. 额定功率:50mW(1/20W)——专为电池供电设备、低功耗传感器等场景设计,避免功率冗余导致的体积浪费,同时保证长期工作无过热风险;
  3. 工作电压:25V——在小信号电路(如模拟信号放大、数字逻辑接口)中电压裕量充足,不会因过压击穿;
  4. 温度系数(TCR):±200ppm/℃——温度每变化1℃,阻值变化±200×10⁻⁶(即0.02%)。按-55℃~+155℃的温差(120℃)计算,总阻值变化可控制在±2.4%以内,满足工业级环境的稳定性;
  5. 工作温度范围:-55℃~+155℃——覆盖工业级、汽车级(常规场景)的温度需求,可在极端温差下长期可靠工作。

三、封装与物理特性

  1. 封装规格:0201(英制),对应公制尺寸约0.6mm×0.3mm×0.23mm(长×宽×高)——是贴片电阻中最小的常用封装之一,可大幅缩小PCB面积,适配便携设备、高密度电路板的小型化设计;
  2. 工艺类型:厚膜工艺——通过丝网印刷、高温烧结在陶瓷基片上形成电阻膜,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,兼顾性价比与可靠性;
  3. 端电极设计:采用镍-锡(Ni-Sn)端电极,符合RoHS环保标准,焊接性能优异,可适配回流焊、波峰焊等常规贴片工艺,焊接后接触电阻稳定,不易因机械应力脱落。

四、环境适应性与可靠性

  1. 温度稳定性:结合±200ppm/℃的TCR与宽温范围,可在高低温交替环境(如北方冬季室外、南方夏季高温车间)中保持阻值稳定,避免电路性能漂移;
  2. 耐湿性:经过防潮涂层处理,可通过JESD22-A101湿度可靠性测试,在高湿度场景(如沿海地区、潮湿工业厂房)中不易出现阻值衰减或失效;
  3. 机械强度:陶瓷基片具有良好的抗冲击性,0201封装可承受常规PCB弯曲(符合IEC 60068-2-21弯曲测试)与振动(符合IEC 60068-2-6振动测试),适配车载、手持设备等振动场景。

五、典型应用场景

该电阻因小体积、低功耗、中等精度的特点,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑、智能穿戴的信号调理电路(音频放大、传感器接口)、电源管理模块(DC-DC转换器反馈电阻);
  2. 工业控制:小型PLC输入输出接口、传感器信号预处理(压力/温度传感器分压网络);
  3. 汽车电子:车载小功率电路(仪表盘背光、中控按键接口),适配-40℃~+85℃的常规车载温度;
  4. 物联网设备:低功耗传感器节点(温湿度/烟雾传感器)的信号处理电路,满足电池供电的低功耗需求。

六、品牌与制造优势

UNI-ROYAL(厚声)作为国内领先的电阻制造商,为该产品提供可靠支撑:

  1. 工艺成熟:拥有20余年厚膜电阻制造经验,自动化生产线保证产品一致性,每批次参数偏差控制在标准范围内;
  2. 质量管控:全流程经过电气性能测试(阻值、精度、功率、TCR等),符合IEC、EIA国际标准,可提供完整的测试报告;
  3. 供货稳定:具备大规模生产能力,可满足客户批量采购需求,交货周期短;
  4. 环保合规:符合RoHS 2.0、REACH等全球环保法规,无铅无镉,适配海外市场要求。

该产品凭借平衡的性能与成本优势,成为电子设计中“小而可靠”的基础元件,可满足多数低功耗、小型化场景的需求。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
