1206W4J0272T5E 产品概述

一、产品简介

1206W4J0272T5E 为 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装为国际通用的1206(3.2 mm × 1.6 mm)。标称阻值 2.7 kΩ,精度 ±5%(J),额定功率 250 mW,额定工作电压 200 V,温度系数(TCR)±100 ppm/°C,工作温度范围 -55 ℃ ~ +155 ℃。该器件属于通用型厚膜 SMD 电阻,适合批量化、成本敏感的电子产品设计中作为分压、限流、上拉/下拉等用途。

二、主要参数要点

  • 阻值:2.7 kΩ ±5%
  • 封装:1206(3.2 × 1.6 mm)贴片
  • 额定功率:250 mW(典型环境下,如 70 ℃)
  • 标称工作电压:200 V(注见说明)
  • 温度系数:±100 ppm/℃(≈0.01%/℃)
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 品牌:UNI-ROYAL(厚声)
  • 推荐应用:通用电子电路、信号处理、功率分配与限流等

三、关键特性与优势

  • 成本效益高:厚膜工艺,适合大批量生产与低成本 BOM 设计。
  • 尺寸与可焊性:1206 标准尺寸,兼容自动贴装与回流焊工艺,良好的机械强度与焊接可靠性。
  • 宽温工作:-55 ℃ 至 +155 ℃,可用于工业级温度环境。
  • 稳定性与线性:TCR ±100 ppm/℃,温度引起的阻值漂移较小,适合一般精度要求的场合。
  • 多用途:通用阻值,广泛用于滤波、偏置、限流与分压网络。

四、使用注意与工程提示

  • 功率与电压关系限制:尽管标称工作电压为 200 V,但实际能承受的电压还受功率限制。根据 P = V²/R,按额定功率 0.25 W 计算,在 2.7 kΩ 时由功耗决定的最大持续工作电压约为 26.0 V(Vmax = √(P·R) ≈ √(0.25×2700) ≈ 25.98 V),对应最大电流约 9.6 mA(Imax ≈ √(P/R))。在电路设计中,如需施加高电压,应特别注意功耗分布与散热条件,避免过热导致性能退化或失效。
  • 温度漂移估算:TCR 为 ±100 ppm/℃,即阻值每升高 1 ℃ 约变化 0.01%。例如温度变化 50 ℃ 时阻值变化约 0.5%。
  • 焊接与回流:可采用标准无铅回流焊工艺,建议遵循厂商的回流温度曲线与湿度等级要求以保证可靠性。
  • 储存与处理:避免潮湿环境长时间暴露,贴片于元件盘(Tape & Reel)中存放并在推荐时间内使用以防焊接问题。

五、典型应用场景

  • 工业控制与测量仪器中的电阻网络与分压器。
  • 电源管理中的限流与反馈回路。
  • 消费电子产品中的偏置与信号处理电路。
  • 通讯设备与仪表的通用电阻元件选型。

六、包装与采购提示

该型号常见包装形式为卷带(Tape & Reel),便于自动贴装。订货时请注明阻值、精度、封装、以及卷带长度(如 2,500 / 5,000 / 10,000 件/卷等)。如有特殊质量认证或阻值筛选(匹配、分档)需求,可与供应商沟通定制服务。

总结:1206W4J0272T5E 是一款面向通用电子应用的经济型厚膜贴片电阻,具有良好的封装兼容性与宽温度适应性。设计时应特别注意功率与电压的关系,确保在安全工作区内使用以获得最佳可靠性与长期稳定性。

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
