0805W8F2003T5E 产品概述

一、产品简介

0805W8F2003T5E 为 UNI-ROYAL(厚声)系列贴片厚膜电阻,封装为行业通用的 0805(公制 2012)规格。标称阻值 200kΩ,精度 ±1%,额定功率 125mW,最高工作电压 150V,温度系数(TCR)±100ppm/℃,工作温度范围 -55℃ 至 +155℃。该型号针对中高阻值、对精度和温漂有一定要求的 SMT 应用设计。

二、主要性能与特点

  • 厚膜工艺,成品阻值稳定、良好的一致性与可重复性。
  • ±1% 精度,适用于精密分压、参考电路和信号处理网络。
  • ±100ppm/℃ TCR,可保持在温度变化下的阻值稳定性(约 0.01%/℃)。
  • 工作温度范围宽 (-55℃ ~ +155℃),适应工业级环境。
  • 支持标准回流焊工艺,适配自动化贴片生产线,抗震动与冲击性能良好。

三、典型电气说明

  • 标称阻值:200 kΩ;误差范围 ±1%。
  • 额定功率:0.125 W(室温条件下)。
  • 最高工作电压:150 V。按 P = V^2 / R 计算,150V 施加于 200kΩ 时产生功耗约 112.5mW,低于额定功率,具有一定的安全裕量。
  • 温度系数 ±100 ppm/℃,表示温度每变化 1℃,阻值变化约 0.01%。

四、封装与工艺兼容性

0805(2012)尺寸,适用于常规 SMT 贴装与回流焊流程。推荐遵循制造商提供的回流曲线进行焊接,避免超出最高回流温度时间窗口以保证可靠性。储存时防潮并避免强酸碱环境,清洗时建议使用对厚膜电阻材料无侵蚀的溶剂。

五、典型应用场景

  • 精密分压器与高阻输入通道的电阻网络。
  • 便携式测试仪、传感器前端、测量电路及信号耦合/偏置回路。
  • 工业控制、通信设备、消费电子中需要稳定高阻值的场合。

六、使用与可靠性建议

  • 在高温或高电压场景下应考虑功率降额(derating),以延长可靠性与寿命。
  • 避免长期在接近额定功率与最高工作电压下连续工作;必要时采取散热或并联降压设计。
  • 贴装时注意避免机械应力集中,焊后进行必要的外观与电气检测以保证品质。

作为一款通用型 0805 厚膜精密电阻,0805W8F2003T5E 在精度、温漂与工作环境适应性之间取得平衡,适用于对空间、成本与性能有综合要求的电子产品设计。若需更详细的规格书(SDS、回流曲线、可靠性试验数据)或样片支持,可联系供应商获取完整技术文件。

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
