1206W4F2002T5E 产品概述

一、产品简介

1206W4F2002T5E 是 UNI-ROYAL(厚声)品牌的贴片厚膜电阻,采用 1206(3216公制)封装,标称阻值 20kΩ,精度 ±1%,额定功率 250mW,最大工作电压 200V。该型号面向对体积、可靠性和中等精度有要求的 SMT 应用,兼顾通用性与成本效益,适合批量生产和自动贴装流程。

二、主要参数

  • 电阻类型:厚膜电阻
  • 阻值:20kΩ(2002 表示 20k)
  • 精度:±1%
  • 额定功率:0.25W(250mW)
  • 最大工作电压:200V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:1206(3216)贴片
  • 品牌:UNI-ROYAL(厚声)

三、性能特点

  • 精度较高:±1% 精度能够满足多数模拟信号、分压与偏置电路对阻值稳定性的要求。
  • 宽温度范围:-55℃ 至 +155℃,适合工业级环境使用。
  • 中等 TCR:±100 ppm/℃ 在常温至中高温范围内保持较好的阻值稳定性,适用于对温漂有一定控制要求的场合。
  • 工业兼容的额定功率与电压:250mW 的功率配合 200V 的耐压,使其在低功率高电压的薄弱电路中也较为适用。
  • SMT 友好:1206 封装适合自动贴装与回流焊工艺,便于大批量组装。

四、典型应用

  • 精密分压器与偏置网络
  • 模拟信号处理、滤波器和放大器电路
  • 测量仪器与数据采集前端(非高精度四级)
  • 电源管理中的检测与反馈网络(满足功率限制)
  • 家电、网络设备与工业控制模块的常规阻值需求点

五、选型与使用建议

  • 功率降额:在高温工作时应按通用降额准则处理,避免在额定功率和高工作温度同时长期工作;若长期接近额定条件,建议选择更高功率等级元件或预留散热空间。
  • 电压考量:最大工作电压为 200V,使用中应保证实际电压不超过该值并留有余量,避免击穿和可靠性问题。
  • PCB 布局:保证焊盘尺寸与 1206 封装匹配,焊接后两端焊点应均匀以减小热应力集中。
  • 焊接工艺:兼容常见的回流焊工艺,建议遵循通用回流温度曲线与清洗流程,避免过度机械应力。
  • 储存与防护:避免潮湿和强腐蚀性气体环境,贴片盘应密封保存,贴装时注意防静电和防污染。

六、可靠性与质量控制

UNI-ROYAL(厚声)在厚膜贴片电阻领域具有成熟的生产工艺和质量控制流程。该型号在制造过程中经过阻值筛选、温度循环、寿命试验和外观检查,满足行业常规可靠性要求。对于有特殊可靠性或认证需求的项目,可与供应方沟通额外测试或批次证明。

七、结论

1206W4F2002T5E 是一款性能均衡、适合批量贴装的 1206 厚膜贴片电阻。其 20kΩ/±1% 的规格、250mW 功率和 200V 工作电压,使其在通用电子设备与工业控制等领域具有良好的适用性。针对高温或高功率场合,建议在电路设计时考虑降额和热管理以确保长期可靠性。若需样品或批量报价,可联系供应商提供器件参数表与出货信息。

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
