1206W4F1001T5E 产品概述

一、产品简介

1206W4F1001T5E 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,阻值 1kΩ,精度 ±1%,额定功率 250mW,适用于常规表面贴装电路的精密限流、分压与偏置等场合。封装为标准 1206(约 3.2×1.6 mm),体积与焊接强度兼顾,便于自动贴装与回流焊工艺。

二、主要电气参数

  • 电阻类型:厚膜电阻
  • 标称阻值:1kΩ(1000 Ω)
  • 精度:±1%
  • 额定功率:250 mW(额定值受环境温度与散热条件影响,见厂商曲线)
  • 最高工作电压:200 V
  • 温度系数(TCR):±100 ppm/°C
  • 工作温度范围:-55 ℃ ~ +155 ℃

三、产品特性

  • 高稳定性:±1% 精度与 ±100 ppm/°C 的温度系数,适合对阻值稳定性有一定要求的应用。
  • 良好的一致性与自动化贴装适配性:1206 封装兼容市面常用的 SMT 设备与回流焊工艺。
  • 宽温区可用:-55 ℃ 到 +155 ℃ 的工作温度范围,满足工业级环境要求。

四、典型应用

  • 电源分压与限流:手机外围电源、便携设备电源管理。
  • 模拟与数字接口电路:上拉/下拉电阻、偏置网络、阻抗匹配。
  • 工业控制与仪表:传感器信号调理、采样电路的精密阻值需求。
  • 消费电子与通信设备:滤波、时序与参考网络。

五、选型与使用建议

  • 温度降额:在高温或散热受限的场合,应根据实际温升对额定功率进行降额处理,或采用更高功率器件。
  • PCB 布局:增大焊盘与散热铜箔可改善功率耗散;避免将高功耗器件密集布局导致局部过热。
  • 电压限制:工作电压接近或高于标称值时,应注意可能的击穿与老化,必要时增加保护电路。
  • 清洗与钝化:遵循制造商推荐的清洗工艺,避免使用强腐蚀性溶剂。

六、可靠性与质量控制

厚膜工艺在长期漂移、焊接热稳定性方面表现良好,但具体可靠性(如湿热、温度循环、机械冲击)应以厂商提供的详细可靠性测试报告为准。选型时可提供样品做过温、过载与长期寿命验证。

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
