WR04X1202FTL 厚膜片式电阻产品概述

WR04X1202FTL是华新科(Walsin) 推出的一款小型化厚膜片式电阻,采用0402标准封装,针对高密度电子电路设计优化,兼具精密性能与宽温适应性,广泛适用于消费电子、工业控制等多领域。

一、产品基本属性

该电阻属于华新科厚膜片式电阻系列,型号编码规则明确:WR代表品牌电阻系列,04X对应0402封装尺寸,1202为阻值代码(表示12kΩ),FTL标识精度等级(±1%)。产品采用表面贴装工艺,无需穿孔,适配自动化贴装生产线,可显著提升电路设计与生产效率。

二、核心性能参数

WR04X1202FTL的关键参数精准匹配实用场景需求:

  • 阻值与精度:12kΩ(1202代码),±1%精度,可实现电路中精准的分压、限流等功能;
  • 功率容量:额定功率62.5mW(即1/16W),适配低功耗电路设计;
  • 工作电压:最大50V(直流/交流),避免超压导致电阻击穿;
  • 温度系数:±100ppm/℃,阻值随温度变化的漂移量可控,适合宽温环境;
  • 工作温度范围:-55℃至+155℃,覆盖工业级、部分汽车电子场景的温度需求。

三、设计特点与优势

  1. 小型化封装适配高密度设计
    0402封装尺寸(约1.0mm×0.5mm),大幅节省PCB空间,特别适合智能手机、可穿戴设备等对体积要求严苛的产品;
  2. 厚膜工艺稳定可靠
    采用丝网印刷+烧结工艺,阻值一致性好,抗机械应力能力优于部分薄膜电阻,长期使用阻值漂移小;
  3. 精密性能覆盖主流需求
    ±1%精度可满足90%以上电子电路应用(如信号调理、电源反馈等),无需额外高精度电阻即可实现设计目标;
  4. 宽温适应性强
    -55℃至+155℃的工作范围,可在极端环境(如工业高温车间、低温户外设备)稳定运行;
  5. 环保合规
    符合RoHS、REACH等国际环保标准,无铅焊接兼容,适配绿色制造要求。

四、典型应用场景

WR04X1202FTL因体积小、性能均衡,广泛应用于以下领域:

  1. 消费电子:智能手机/平板的射频信号调理电路、电源分压网络、传感器接口电路;
  2. 可穿戴设备:智能手环/手表的心率传感器偏置电路、低功耗MCU周边电路;
  3. 工业控制:小型PLC的I/O接口电阻、温度传感器的信号放大电路;
  4. 通信设备:小型基站的射频辅助电路、路由器的电源滤波电路;
  5. 汽车电子(辅助场景):车载USB充电模块的限流电路、小型传感器(如胎压监测)的信号处理电路。

五、使用注意事项

为确保产品性能与寿命,需注意以下要点:

  1. 功率降额使用:实际电路功率建议不超过额定功率的60%(≤37.5mW),避免过热导致阻值漂移或损坏;
  2. 电压限制:避免施加超过50V的工作电压,若需更高电压,需选择同阻值更高电压等级的电阻;
  3. 焊接工艺:回流焊需遵循华新科推荐曲线(峰值温度≤245℃,时间≤30s),避免冷焊或过热;
  4. 存储条件:未开封产品存储于25℃±5℃、湿度40%±10%环境,开封后建议1年内使用完毕。

六、总结

WR04X1202FTL作为华新科0402封装厚膜电阻的代表型号,以小型化、精密性、宽温适应性为核心优势,平衡了性能与成本,是高密度电子电路设计的优选元件。其参数覆盖主流应用场景,可满足消费电子、工业控制等领域的多样化需求。

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
