WR06X4701FTL 厚膜贴片电阻产品概述

WR06X4701FTL是华新科(Walsin)推出的一款0603封装厚膜电阻,针对小型化、低功耗电路设计,兼顾精度、温度稳定性与成本优势,广泛应用于消费电子、工业控制等领域。

一、产品基本定位

该电阻属于通用型贴片厚膜电阻,核心定位为小型化电路的信号调理与功率限制元件:既满足±1%精度的基本测量需求,又通过100mW功率规格适配低功耗场景,同时-55℃~+155℃的宽温范围覆盖工业级环境要求,是批量应用的高性价比选择。

二、核心参数深度解析

2.1 阻值与精度

  • 标称阻值:4.7kΩ(标识代码“4701”,即470×10¹=4700Ω);
  • 精度等级:±1%,优于普通±5%电阻,可满足模拟电路(如分压、滤波)的阻值误差要求。

2.2 功率与电压平衡

  • 额定功率:100mW(1/10W),适配低功耗电路(如MCU IO口限流、传感器偏置);
  • 额定电压:75V,需注意电压与功率的双重限制:实际使用中需同时满足(P=U^2/R≤0.1W),即最大允许电压约21.8V(电流≈4.6mA),避免仅看75V导致过功率损坏。

2.3 温度特性

  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化0.01%;
  • 工作温度范围:-55℃~+155℃,覆盖工业级环境(如户外设备、车载辅助系统),极端温差下阻值变化可控(210℃温差时最大变化约2.1%)。

三、封装与物理特性

3.1 封装尺寸

  • 英制:0603(对应公制1608),即长0.06英寸、宽0.03英寸;
  • 公制:长1.6mm±0.15mm,宽0.8mm±0.1mm,厚度0.4mm±0.1mm,体积小巧适配高密度PCB布局。

3.2 材料工艺

  • 基片:氧化铝陶瓷,热稳定性好;
  • 电阻层:钌系厚膜浆料,成本低于薄膜电阻,功率密度高于碳膜电阻;
  • 端电极:银钯合金+镍镀层,焊接性优异,适配回流焊、波峰焊工艺。

四、典型应用场景

  1. 消费电子:手机、平板、智能穿戴的信号分压、滤波电路(如音频接口、电源指示灯限流);
  2. 工业控制:PLC、传感器接口的偏置电阻、限流保护(如温度传感器信号调理);
  3. 汽车电子:车载USB、胎压监测的辅助电路(非安全关键件,宽温适配车载环境);
  4. 通信设备:小型基站、路由器的射频匹配网络、电源分压(0603封装适配高密度布局);
  5. 医疗设备:小型监护仪的信号调理电路(精度与稳定性满足基本临床需求)。

五、品牌与可靠性优势

华新科作为全球被动元件头部厂商,WR06X4701FTL具备以下优势:

  • 质量体系:通过ISO9001、IATF16949认证,生产工艺成熟,产品一致性好;
  • 可靠性:厚膜电阻抗过载能力优于薄膜电阻,长期工作阻值漂移小;
  • 供应链稳定:量产能力强,交货周期短,适合批量采购需求。

六、使用注意事项

  1. 功率限制:实际功率不得超过100mW,避免过功率导致阻值漂移或烧毁;
  2. 静电防护:贴片电阻易受静电损坏,生产、测试需采用静电防护措施;
  3. 焊接工艺:回流焊峰值温度≤245℃(时间≤10s),避免手工焊接温度过高;
  4. 环境温度:不得长期工作在155℃以上,否则温漂增大影响电路性能。

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
