华新科WR04X1001FTL厚膜电阻产品概述

一、产品基本定位与型号解析

华新科WR04X1001FTL是一款厚膜贴片电阻,属于华新科常规贴片电阻产品线中的高精度小功率型号。型号命名逻辑清晰:

  • “WR”代表华新科厚膜电阻系列;
  • “04X”对应0402英制封装(公制1005尺寸,即长1.0mm×宽0.5mm);
  • “1001”表示标称阻值1kΩ(前三位为有效数字100,第四位为倍率10¹);
  • “FTL”后缀对应**±1%精度**、±100ppm/℃温度系数及0402封装规格。

该产品主打小体积、高精度、宽温适应性,适配高密度电路设计需求。

二、核心性能参数详细说明

该型号的关键参数可满足多数中低端至中端电子设备的阻值控制需求,具体如下:

  1. 阻值与精度:标称阻值1kΩ,精度±1%——在分压、限流、滤波等电路中,±1%精度可有效降低信号失真或功率误差,适合对阻值稳定性有要求的场景;
  2. 功率与电压额定值:额定功率1/16W(即62.5mW),最大工作电压50V——经计算,最大安全电流约1.25mA((I=P/V)),适配低功耗电路,避免过功率损坏;
  3. 温度系数:±100ppm/℃——温度每变化1℃,阻值变化约0.1Ω(1kΩ×100ppm);在-55℃~+155℃范围内,总阻值变化约±2.1Ω,稳定性满足工业级要求;
  4. 工作温度范围:-55℃+155℃——覆盖消费电子(-40℃+85℃)、工业控制(-55℃~+125℃)甚至部分高温场景,环境适应性强。

三、封装特性与典型应用场景

  1. 封装优势:0402封装体积极小,可大幅缩小PCB板面积,提升电路集成度,适合小型化设备;
  2. 典型应用:
    • 消费电子:智能手机、可穿戴设备(智能手环)的电源管理、信号滤波电路;
    • 物联网终端:小型传感器节点、WiFi/Bluetooth模块的分压限流;
    • 工业控制:小型PLC、电机驱动辅助电路的低功耗阻值控制;
    • 汽车辅助电路:车载小功率传感器、显示屏背光控制(需结合具体车规要求)。

四、可靠性与环境适应性

华新科的生产工艺保障了该型号的可靠性:

  1. 厚膜工艺优势:采用丝网印刷+烧结工艺,膜层附着力强,抗机械冲击、振动性能优于薄膜电阻,适合手持、车载等振动场景;
  2. 宽温稳定性:经测试,工作温度范围内阻值漂移符合规格书,无明显跳变或失效;
  3. 环保合规:符合欧盟RoHS指令(无铅、无镉等有害物质),适配全球市场;
  4. 批量一致性:生产工艺成熟,批量产品阻值、精度一致性好,降低电路调试难度。

五、总结

华新科WR04X1001FTL厚膜电阻凭借小体积(0402封装)、高精度(±1%)、宽温范围(-55℃~+155℃)、低功耗(1/16W) 等核心优势,成为消费电子、物联网、小型工业控制等领域的高性价比选择。其厚膜工艺带来的可靠性,结合华新科的品牌质量保障,可满足多数常规电路的阻值控制需求,是贴片电阻选型中平衡性能与成本的理想型号。

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
