0201WMF2203TEE 产品概述

一、产品简介

0201WMF2203TEE 是 UNI-ROYAL(厚声)推出的一款超小型贴片厚膜电阻,封装为 0201,阻值 220kΩ,精度 ±1%,额定功率 1/20W(50mW),额定工作电压 25V,温度系数(TCR) ±200ppm/℃,工作温度范围 -55℃ 至 +155℃。该产品专为高密度、轻薄便携电子设备及精密信号链路中的高阻值应用设计,兼顾体积和精度要求。

二、主要性能参数

  • 阻值:220kΩ
  • 精度:±1%
  • 功率:50mW(1/20W)
  • 最大工作电压:25V
  • 温度系数:±200ppm/℃(典型,随批次略有差异)
  • 工作温度:-55℃ ~ +155℃
  • 制程:厚膜(thick film)
  • 封装:0201(超小型贴片)

三、产品特点

  • 超小尺寸:0201 封装,利于高密度贴片与微型化设计。
  • 精度较高:±1% 满足多数精密分压、偏置及滤波网络需求。
  • 宽温工作:-55℃ 到 +155℃,适合严苛环境下长期工作。
  • 良好稳定性:厚膜工艺在一般温度与湿度条件下表现稳定,适合量产应用。
  • 兼容表面贴装工艺:适用于常见回流焊工艺,便于 SMT 生产线贴装。

四、典型应用场景

  • 手持终端、穿戴设备等体积受限产品的分压与偏置网络。
  • 高密度主板与模块(如无线通讯模块、传感器前端)中用作高阻值元件。
  • 精密测量电路、输入阻抗较高的放大器和滤波器。
  • 低功耗电路中作为上拉/下拉电阻、泄放电阻等(注意功率与最大工作电压限制)。

五、设计与使用注意事项

  • 功率与温升:50mW 为额定功率,实际电功率消耗及环境温度会影响热性能,建议按厂家热降额曲线进行设计与留有余量。在高温环境下应适当降额。
  • 电压限制:最大工作电压 25V,超出该值会使电阻失效或漂移,设计时需确保工作电压安全。
  • 脉冲与瞬态:0201 厚膜电阻不适宜承受大幅度脉冲能量或频繁大的电压冲击,关键场合请评估脉冲能量并考虑更大功率元件。
  • 封装与焊接:建议按照组件供应商或 IPC 推荐的焊盘尺寸和回流焊曲线进行焊接,避免过度加热或机械应力。过度弯曲 PCB 可能导致焊点开裂或电阻破坏。
  • 杂讯与稳定性:厚膜电阻噪声和长期漂移性能相较于金属膜有差异,如电路对噪声和长期漂移敏感,应在选型时做可靠性评估。

六、装配与可靠性建议

  • 建议采用卷带(Tape & Reel)供料以适配自动贴片机,提升贴装效率与良品率(具体包装形式请向供应商确认)。
  • 在制程中遵循常规 SMT 管理流程:合理的锡膏印刷、贴装校准和回流焊温度曲线控制,可有效降低电阻损伤与偏移风险。
  • 对于关键应用,建议进行样件环境应力测试(高低温循环、湿热、振动)以验证长期可靠性。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
