华新科WR06X681JTL厚膜片式电阻产品概述

一、产品基本定位与核心参数

华新科WR06X681JTL是一款0603封装厚膜片式电阻,针对商用及工业级场景设计,核心参数清晰明确:

  • 阻值:680Ω(标识“681”,代表68×10¹Ω);
  • 精度:±5%(标识“J”,满足常规电路误差要求);
  • 额定功率:100mW(25℃环境下持续工作功率);
  • 额定电压:75V(直流/交流峰值电压上限);
  • 温度系数:±100ppm/℃(阻值随温度变化的稳定性);
  • 工作温度:-55℃~+155℃(覆盖宽温应用);
  • 品牌:华新科(Walsin),型号中“X”为系列前缀,“TL”为封装/性能标识。

二、封装与尺寸规格

采用国际通用0603表面贴装封装,尺寸符合行业标准:

  • 英制:0.06英寸(长)×0.03英寸(宽);
  • 公制:1.6mm×0.8mm(长×宽),厚度约0.45mm;

该封装兼容绝大多数SMT生产线,支持高速贴装,适合小型化电子设备的高密度设计(如手机、智能穿戴、微型传感器模块),可有效节省PCB板空间。

三、电气性能参数详解

3.1 阻值与精度

实际工作阻值范围为646Ω~714Ω,无需额外校准即可适配信号调理、滤波、分压等常规电路,满足商用场景的误差要求。

3.2 功率与电压约束

需注意双重约束逻辑:

  • 功率约束:由P=U²/R推导,100mW功率下最大电压≈8.25V;
  • 电压约束:75V为绝缘耐压上限,但实际工作电压需取“功率约束电压(8.25V)”与“75V”中的较小值,避免过功率损坏。

3.3 温度系数与稳定性

温度系数±100ppm/℃意味着:每变化1℃,阻值变化±0.01%。例如:

  • 25℃→155℃(温差130℃):阻值变化±1.3%,仍在±5%精度内;
  • 25℃→-55℃(温差80℃):阻值变化±0.8%,稳定性满足宽温需求。

四、环境适应性与可靠性

4.1 宽温工作能力

-55℃+155℃的温度范围,覆盖**工业级(-40+85℃)、汽车电子(部分场景-40~+125℃)及高温工业场景**(如发动机舱、工业烤箱周边电路),无需额外散热即可稳定工作。

4.2 可靠性验证

华新科对该产品进行多项行业标准测试:

  • 负载寿命:1000小时额定功率下,阻值变化≤±1%;
  • 湿度测试:85℃/85%RH环境1000小时,阻值变化≤±2%;
  • 浪涌抗扰:符合IEC 61000-4-5标准,抗脉冲电压能力强;
  • 环保合规:通过RoHS 2.0、REACH认证,不含铅、镉等有害物质。

五、典型应用场景

因尺寸小、性能稳定,广泛应用于:

  1. 消费电子:手机音频滤波、智能手表传感器信号调理、蓝牙耳机电源分压;
  2. 工业控制:PLC模拟量输入电路、小型变频器信号放大、工业传感器接口;
  3. 汽车电子:车载摄像头信号滤波、仪表盘背光驱动分压、胎压监测模块;
  4. 通信设备:路由器电源滤波、交换机信号匹配、5G小基站辅助电路;
  5. 医疗电子:小型血糖仪信号调理、体温计温度传感器接口。

六、品牌与品质保障

华新科作为全球被动元件领先厂商,WR06X系列具有以下优势:

  • 工艺:先进厚膜印刷技术,阻值一致性达±0.1%以内(批量);
  • 认证:通过ISO 9001、IATF 16949(汽车电子)认证;
  • 供应:全球生产基地布局,批量供应稳定,交货周期≤2周;
  • 技术:提供降额曲线、电路设计咨询等服务,帮助客户优化方案。

该产品凭借成本优势与稳定性能,成为中小功率电路设计的常规选择,适用于对尺寸、可靠性有要求的多数场景。

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
