WA04X103JTL 片式排阻产品概述

WA04X103JTL是华新科(Walsin)推出的一款4位表面贴装排阻,专为高密度、小型化电子电路设计,集成4个独立的10kΩ电阻,适配0402封装(2.0mm×1.0mm),兼顾性能与空间效率,广泛应用于消费电子、汽车电子等领域。

一、产品基本信息

该型号属于华新科0402封装排阻产品线,型号命名规则清晰:“WA04X”对应0402封装的排阻系列,“103”代表标称阻值为10kΩ(10×10³Ω),“J”为精度代码(对应±5%),“TL”为封装及工艺标识。产品采用8引脚SMD封装,由4个10kΩ电阻集成,每个电阻独立工作,满足多电阻并行布局的需求,有效节省PCB空间。

二、核心性能参数

WA04X103JTL的性能参数针对通用电路需求优化,关键指标如下:

  1. 阻值与精度:标称阻值10kΩ,精度等级±5%,符合E24电阻系列的公差要求,可满足信号分压、滤波、偏置等电路的阻值匹配需求;
  2. 功率与电压:单个电阻额定功率为62.5mW(即1/16W),额定工作电压50V,在额定条件下可长期稳定工作,无过热或阻值漂移风险;
  3. 温度特性:温度系数为±200ppm/℃,即环境温度每变化1℃,阻值变化不超过±0.02%,适用于温度波动较大的应用场景(如汽车舱内、工业现场);
  4. 封装尺寸:采用SMD 0402封装,尺寸为2.0mm×1.0mm,厚度符合行业标准,适配回流焊、波峰焊等常规表面贴装工艺,支持批量生产。

三、封装与典型应用场景

3.1 封装特点

0402封装是当前小型化电子设备的主流封装之一,表面贴装兼容性强,可通过自动化设备快速装配,降低人工成本。该封装的引脚间距符合行业规范,焊接可靠性高,不易出现虚焊问题。

3.2 典型应用

  • 消费电子:智能手机、智能手表的传感器接口电路(多个10kΩ电阻用于信号分压、滤波,4位排阻简化布局);
  • 汽车电子:车载胎压监测、座椅调节等小型控制模块(宽温特性适应汽车舱内温度变化,稳定的阻值确保信号准确);
  • 工业控制:PLC输入输出接口(长期稳定性满足工业设备的7×24小时工作需求);
  • 通信设备:无线基站射频前端偏置电路(4位排阻替代多个独立电阻,提高电路集成度与可靠性)。

四、品牌与可靠性保障

华新科作为全球知名的被动元件供应商,其产品通过ISO9001、ISO14001等体系认证,符合RoHS、REACH等环保法规要求。WA04X103JTL的可靠性体现在:

  • 耐焊接热:可承受260℃回流焊3次(每次10秒以内),无开裂、锡裂或阻值漂移问题;
  • 长期稳定性:额定工作条件下,阻值漂移率≤0.5%/1000小时,适合长期使用的设备;
  • 宽温工作:工作温度范围为-55℃至125℃,可适应极端环境(如沙漠地区的户外设备);
  • 静电防护:符合ESD相关标准,降低生产及使用过程中的静电损伤风险。

五、选型与使用注意事项

  1. 选型确认:需核对封装类型(0402)、排阻位数(4位)、阻值(10kΩ±5%)、引脚数(8脚),避免与0603等其他封装混淆;
  2. 功率降额:实际工作功率建议不超过额定功率的80%(即≤50mW),延长产品寿命并提高可靠性;
  3. 焊接规范:回流焊温度曲线需参考华新科提供的工艺参数,避免局部过热导致电阻损坏;
  4. 存储与运输:存储环境温度-40℃至60℃,湿度≤60%,运输过程中避免剧烈振动,防止引脚变形;
  5. 静电防护:生产过程中佩戴静电手环,使用静电袋存储,避免静电放电损坏。

综上,WA04X103JTL凭借小型化封装、稳定的性能及可靠的品质,成为多电阻并行电路的理想选择,适用于各类对空间与性能有要求的电子设备。

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
