0201WMF1303TEE 厚膜贴片电阻产品概述

一、产品核心基本信息

0201WMF1303TEE是厚声电子(UNI-ROYAL) 推出的超小型厚膜贴片电阻,专为高密度PCB布局场景优化,核心参数清晰明确:

  • 电阻类型:厚膜贴片电阻
  • 封装规格:0201(英寸制,对应公制约0.508mm×0.254mm)
  • 标称阻值:130kΩ(四位代码标识为「1303」,即130×10³Ω)
  • 精度等级:±1%(常温25℃下阻值偏差范围)
  • 额定功率:50mW(最大允许功耗)
  • 工作电压:25V(最大直流/交流工作电压)
  • 温度系数:±200ppm/℃(阻值随温度变化的比率)
  • 工作温度范围:-55℃至+155℃(工业级宽温范围)

二、关键性能参数深度解析

2.1 阻值与精度

该电阻标称阻值130kΩ,采用四位数字代码标识(1303),前三位为有效数字(130),第四位为倍率(10³),阻值计算准确。±1%的精度等级在厚膜电阻中属于较高水平,满足多数中等精度电路需求(如分压、反馈、信号调理等),无需额外校准即可稳定工作。

2.2 功率与电压限制

额定功率50mW是最大允许功耗,需注意功率与电压的联动限制:根据公式 ( P = \frac{U^2}{R} ),当工作电压达到25V时,实际功耗约为 ( \frac{25^2}{130×10^3} ≈ 4.8mW ),远低于额定功率,因此实际使用需优先遵循电压限制(不超过25V),避免绝缘击穿。

2.3 温度特性与宽温范围

温度系数±200ppm/℃表示:温度每变化1℃,阻值变化±200×10⁻⁶。以155℃为例,相对于25℃基准,阻值变化约3.38kΩ(仅描述温度漂移,与常温精度±1%不冲突)。-55℃至+155℃覆盖工业环境(-40℃+85℃)和部分汽车电子场景(-55℃+150℃),满足极端温度下的稳定工作。

三、封装与工艺优势

3.1 0201超小型封装

0201是当前贴片电阻最小规格之一,体积仅0.02英寸×0.01英寸,适合便携电子、小型化模块(如智能手机传感器、智能穿戴)的高密度布局,可有效缩小PCB面积,降低整机体积。

3.2 厚膜工艺特点

采用厚膜丝网印刷工艺,在氧化铝陶瓷基片上印刷电阻浆料后烧结而成,优势显著:

  • 成本适中:相比薄膜电阻更经济,适合批量应用;
  • 稳定性好:陶瓷基片热膨胀系数低,长期工作阻值漂移小;
  • 耐冲击强:可承受短时间过压/过流冲击(如脉冲信号),可靠性高。

四、典型应用场景

因小型化、宽温、中等精度的特点,该电阻广泛应用于:

  1. 消费电子:智能手机摄像头模块、触控传感器接口;
  2. 工业控制:小型PLC输入输出模块、传感器节点(温度/压力信号调理);
  3. 通信设备:小型基站、路由器射频前端分压电路、数字电路限流;
  4. 汽车电子:仪表盘背光电路、中控辅助模块(非高温区域)。

五、使用注意事项

  1. 功率余量:实际功率建议不超过30mW(留60%余量),避免长期过载漂移;
  2. 焊接工艺:回流焊峰值温度控制在240℃~260℃,时间不超过10秒,防止封装损坏;
  3. 静电防护:0201封装小,需采用ESD防护(接地工作台、防静电包装);
  4. 选型匹配:若需±0.1%精度或±50ppm/℃温度系数,需选薄膜电阻,避免性能过剩。

该产品平衡了小型化、精度、成本与宽温特性,是多数对尺寸敏感且需中等精度电路设计的理想选择。

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
