WR04X102JTL厚膜固定电阻器产品概述

一、核心电气参数与规格说明

WR04X102JTL是华新科(Walsin)推出的厚膜固定电阻器,核心参数精准匹配常规电路设计需求,关键规格如下:

  • 阻值:1kΩ(采用三位数字代码“102”标识,前两位为有效数字“10”,第三位为零的个数“2”,即10×10²=1000Ω);
  • 精度:±5%(行业标准J档精度,满足多数民用、工业常规电路的阻值误差要求,无需高精度校准即可适配基础电路);
  • 额定功率:62.5mW(0.0625W),适配低功耗电路的功率负载(1kΩ下最大允许电流约7.9mA);
  • 最大工作电压:50V,确保电路电压波动(如电源纹波)时的安全运行,避免击穿风险;
  • 温度系数:±100ppm/℃,即温度每变化1℃,阻值变化约0.01%,宽温环境下保持阻值稳定;
  • 工作温度范围:-55℃~+155℃,覆盖工业级及部分汽车电子的温区要求,适应极端环境长期运行。

二、封装工艺与物理特性

1. 封装规格

采用0402封装(英制尺寸,对应公制1005),物理尺寸约为1.0mm×0.5mm×0.5mm(长×宽×高),是小型化电子设备的主流封装之一,可有效节省PCB布局空间。

2. 厚膜工艺特点

以高纯度氧化铝陶瓷为基底,通过以下工序制造:

  • 丝网印刷厚膜电阻浆料(如钌系浆料);
  • 高温烧结形成致密电阻层;
  • 电极制备(端电极+焊接层),确保贴装可靠性。
    该工艺兼具成本优势与性能稳定性,适合批量生产。

3. 贴装兼容性

适配常规表面贴装(SMT)生产线,可实现高速贴装(贴装速度≥10k pcs/h),支持回流焊、波峰焊等工艺,降低生产难度。

三、性能特点与可靠性

WR04X102JTL在常规场景下表现出以下核心优势:

  • 宽温稳定性:-55℃~+155℃的工作范围,可满足户外设备(如智能安防摄像头)、工业传感器模块等高低温交替环境需求;
  • 阻值一致性:华新科厚膜工艺确保批量产品阻值偏差控制在±5%以内,减少电路调试复杂度(如分压电路无需反复校准);
  • 低噪声特性:优化的电阻浆料配方降低了电阻噪声(典型噪声电压约1nV/√Hz),适合信号调理、音频电路等对噪声敏感的场景;
  • 长期可靠性:经过70℃/1000h老化测试,阻值变化率≤1%;通过温度循环(-55℃~155℃,500次)、湿度试验(85℃/85%RH,1000h),符合行业可靠性标准。

四、典型应用场景

因小体积、宽温范围及稳定性能,WR04X102JTL广泛应用于以下领域:

  1. 消费电子:智能手机、智能手表的电源管理模块(分压、限流电路)、信号滤波电路;
  2. 便携无线设备:蓝牙耳机、运动手环的射频信号调理、低功耗传感器接口电路;
  3. 工业控制:小型PLC模块、传感器节点(温度/压力传感器)的信号放大、偏置电路;
  4. 汽车电子:非严苛环境的辅助电路(如车内氛围灯控制、低功耗传感器接口);
  5. 物联网设备:智能家居节点(智能插座、温湿度传感器)的信号处理电路。

五、品牌与质量保障

华新科(Walsin)作为全球知名被动元件制造商,具备30余年厚膜电阻生产经验,产品质量与供应链支持具备以下优势:

  • 合规性:符合RoHS 2.0、REACH等环保法规,无铅无卤,适配绿色电子产品设计;
  • 质量体系:通过ISO 9001、IATF 16949认证,产品一致性与可靠性得到汽车、工业客户认可;
  • 供应链支持:全球布局生产基地(中国大陆、台湾、泰国)与销售网络,可满足批量采购需求,支持定制化(特殊阻值、封装)。

WR04X102JTL以平衡的性能、成本与可靠性,成为小型化电子设备中基础电阻的优选方案。

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
