  • 功率额定:125 mW(在额定环境温度下)
  • 最大工作电压:150 V
  • 温度系数(TCR):±100 ppm/℃(典型标称)
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 制程:厚膜电阻

三、产品特点

  • 高精度:±1% 工艺控制,适用于需要稳定阻值的回路(如分压、偏置网络)。
  • 高阻值应用:300 kΩ 的额定阻值适合高输入阻抗或微弱信号电路。
  • 宽温区适应性:可在-55 ℃ 至 +155 ℃ 环境下工作,适配工业级温度需求。
  • SMT 兼容:0805 尺寸适合常见贴片机与回流焊工艺,利于自动化生产与高密度板设计。
  • 稳定性与重复性良好:厚膜电阻在常规工况下具有良好的长期稳定性与批次一致性。

四、典型应用场景

  • 模拟电路中的高阻抗分压器、偏置与反馈网络
  • 传感器信号调理、滤波器的阻抗设定
  • 移动设备、消费电子与工业控制板的通用阻值需求
  • 测量仪器与数据采集系统中需要较高电阻值与稳定性的场合

五、可靠性与环境适应性

该系列电阻设计用于满足电子产品常见的可靠性要求,通常经过焊接热冲击、温度循环、负载寿命与湿热试验等项目验证。对于高温或持续大功率工况,应参照厂方提供的功率降额曲线(Power derating)与寿命测试数据,合理留有余量以确保长期可靠性。

六、封装、焊接与使用注意事项

  • 封装与贴装:0805 标准尺寸,适配常规 SMT 贴装设备;建议参考 IPC-7351 的 PCB 焊盘设计指南以获得最佳焊接质量。
  • 回流焊兼容性:兼容标准无铅或有铅回流工艺;为保证性能与可靠性,建议遵循焊膏供应商与元件厂的回流曲线建议,避免过高峰值温度或过长高温保温。
  • 温度与功率管理:在高环境温度或高密度布板情形下,需按功率降额原则使用,以防过热导致电阻值漂移或失效。
  • 防潮与存储:未立即使用时建议按元件供货商要求进行防潮包装保存,避免长期受潮影响焊接性与电气性能。
  • 静电与机械:在搬运与贴装过程中应避免强烈冲击或弯折,应采取常规 ESD 防护措施。

七、订购与包装信息

典型料号 0805W8F3003T5E 中“0805”表示封装规格,“3003”对应厂方阻值标识(300 kΩ),后缀通常包含包装形式(例如卷带/盘装等)。实际包装单位(卷带数量)与交付条件请参照 UNI-ROYAL 的产品目录或向供应商确认。

备注:以上为基于常规规格与应用整理的概述性说明。对更详细的电气特性、功率降额曲线、可靠性试验数据与推荐回流曲线,请参阅厂方完整数据手册或直接咨询 UNI-ROYAL(厚声)技术支持。

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
