0201WMF1872TEE 贴片厚膜电阻产品概述

一、产品基本识别

0201WMF1872TEE是厚声电子(UNI-ROYAL) 推出的常规精度贴片厚膜电阻,型号编码对应核心特性清晰可辨:

  • 前缀“0201”:英制封装尺寸(0.02英寸×0.01英寸,公制约0.5mm×0.25mm);
  • “WMF”:厚声厚膜电阻系列标识,代表陶瓷基片+厚膜电阻浆料的成熟工艺;
  • “1872”:阻值代码(前三位187为有效数字,后一位2为倍率10²,即187×10²=18.7kΩ);
  • 后缀“TEE”:内部参数编码,对应精度±1%、温度系数±200ppm/℃等关键指标。

该产品定位为“性能均衡型贴片电阻”,兼顾小体积、宽温适应性与成本优势,适配多数中小型电子设计。

二、核心电气性能参数

关键电气指标直接决定应用场景,具体如下:

  1. 阻值与精度:标称阻值18.7kΩ,精度±1%(E96系列阻值,满足电路对阻值一致性的基本要求);
  2. 功率容量:额定功率50mW(1/20W),实际应用建议降额至30mW以内(避免长期过热导致阻值漂移);
  3. 工作电压:额定电压25V,击穿电压约为额定值的2~3倍(需避免瞬时过压,防止绝缘层击穿);
  4. 温度系数:±200ppm/℃(温度每变化1℃,阻值变化约3.74Ω,满足普通环境下的稳定性需求);
  5. 宽温范围:-55℃~+155℃,覆盖工业级与车载环境的温度波动(部分批次通过AEC-Q200车载认证)。

三、封装与物理特性

0201封装是小型化电子设备的主流选择,物理特性适配高密度布局:

  • 尺寸规格:公制约0.50mm(长)×0.25mm(宽)×0.15mm(厚),英制0201(0.02″×0.01″);
  • 封装工艺:表面贴装(SMD),无引脚设计,适配自动化贴装生产线(贴装精度要求≥±0.05mm);
  • 材质结构:氧化铝陶瓷基片+厚膜电阻浆料,表面涂覆环氧树脂保护层(抗潮湿、抗机械划伤);
  • 重量:单颗约0.001g,单位面积贴装密度可达40000颗/m²,适合便携设备的紧凑设计。

四、典型应用场景

基于小封装、宽温、常规精度的特点,该电阻适用于以下场景:

  1. 消费电子:手机、平板、智能音箱的信号滤波、电源分压电路(小体积适配便携设备的空间限制);
  2. 可穿戴设备:智能手环、手表的传感器偏置、低功耗控制电路(宽温范围适配人体佩戴的温度变化);
  3. 工业控制:小型PLC、温度采集模块的输入电路(-55℃~+155℃覆盖工业现场的极端温度);
  4. 车载电子:汽车仪表盘、倒车雷达的辅助电路(符合车载电子的环境可靠性要求);
  5. 通信设备:小型路由器、无线模块的射频匹配电路(小体积适配高密度通信板的布局需求)。

五、品牌与可靠性优势

厚声电子(UNI-ROYAL)作为国内被动元器件主流厂商,该产品具备以下可靠性优势:

  1. 工艺稳定性:厚膜生产工艺成熟,批次阻值一致性偏差控制在±0.5%以内(优于标称精度);
  2. 环保合规:符合RoHS 2.0、REACH等国际标准,无铅无卤,适合出口产品;
  3. 认证齐全:通过IEC 60115-1(固定电阻通用标准)、AEC-Q200(车载电子标准,部分批次);
  4. 成本控制:厚膜工艺成本低于薄膜电阻,适合中低端到中端电子设计的成本平衡需求。

六、选型与使用注意事项

为保证长期性能稳定,使用时需注意以下要点:

  1. 功率降额:实际工作功率建议不超过额定值的60%(30mW以内),避免过热老化;
  2. 焊接规范:回流焊峰值温度≤260℃(时间≤10秒),波峰焊温度≤245℃(时间≤5秒),防止封装损坏;
  3. 环境适配:避免在强腐蚀、高湿度(>90%RH)环境长期使用(可配合防护涂层增强可靠性);
  4. 精度匹配:若需更高精度(±0.1%)或更低温度系数(±50ppm/℃),需选择薄膜电阻或厚声高端系列。

该产品以“小体积、宽温、高性价比”为核心竞争力,是多数中小型电子设备电阻选型的常规之选。

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
