BOURNS CR0402-J/-000GLF 厚膜贴片0Ω电阻产品概述

一、产品核心定位与应用场景

BOURNS CR0402-J/-000GLF是一款针对高密度PCB设计优化的厚膜贴片0Ω电阻,核心定位为替代传统插件跳线、实现电路低阻抗连接的基础元件。其小体积、宽温稳定的特性,广泛适配消费电子、工业控制、通信设备等领域的常规与恶劣环境应用,解决了传统跳线占用空间大、可靠性低的痛点。

二、关键参数与性能特点

1. 核心参数

  • 阻值:标称0Ω(实际寄生电阻<50mΩ,满足常规低阻抗需求);
  • 精度:±5%(相对寄生电阻的偏差范围,适用于非精密低阻抗场景);
  • 功率:额定功率62.5mW(持续工作功率,峰值功率可短暂提升至125mW);
  • 工作温度:-55℃~+155℃(覆盖工业级宽温范围,支持高低温交替环境)。

2. 性能优势

  • 低阻抗损耗:厚膜工艺实现陶瓷基片与金属镀层的紧密结合,寄生电阻远低于传统跳线,减少信号传输损耗与功率消耗;
  • 宽温稳定性:在极端温度下阻值漂移控制在±1%以内(长期使用),满足户外设备、工业控制器的环境适应性要求;
  • 小体积集成:0402封装适配高密度PCB布局,可贴装于多层板的任意层,提升电路集成度。

三、封装与物理特性

1. 封装规格

  • 英制:0402(对应公制1005);
  • 尺寸:长度1.0±0.1mm,宽度0.5±0.1mm,厚度0.35±0.05mm;
  • 端电极:镍/锡双层镀层(兼容无铅回流焊工艺,符合RoHS标准)。

2. 包装与存储

  • 包装:8mm卷带(每盘10000片),适合自动化贴装线;
  • 存储:未开封产品需存于25℃±5℃、湿度≤60%RH环境,开封后建议1个月内用完,避免受潮导致焊接不良。

四、可靠性与环境适应性

1. 环境测试验证

  • 温度循环:通过-55℃~+155℃(1000次循环)测试,阻值变化≤0.5%;
  • 湿度测试:85℃/85%RH(1000小时)测试,无腐蚀、阻值漂移≤0.8%;
  • 振动测试:符合IEC 60068-2-6标准(10~2000Hz,加速度2g),无开路或性能下降。

2. 寿命特性

在额定功率与25℃环境下,连续工作10000小时后,阻值变化率≤1%,满足工业设备5年以上使用寿命要求。

五、典型应用场景详解

1. 电路跳线替代

传统插件跳线需手工焊接,易出现虚焊、占用空间大;本产品可直接贴装于PCB,实现不同线路层/焊点的连接,提升生产效率与可靠性,常见于手机主板、平板电池保护板。

2. 射频路径优化

在4G/5G基站、路由器等射频设备中,用于接地或信号路径的低阻抗连接,减少射频信号损耗(寄生电阻<50mΩ可降低信号衰减),提升通信稳定性。

3. 工业设备抗干扰

PLC、变频器等工业控制器中,作为滤波电路的旁路元件,抑制电磁干扰(EMI),避免信号失真影响设备运行。

4. 汽车电子辅助电路

适配汽车座舱、车身控制模块的低阻抗连接(如传感器信号路径),宽温特性满足汽车-40℃~+85℃的工作环境(需确认具体车规认证,本产品基础参数覆盖该温区)。

六、选型与使用注意事项

1. 功率降额要求

实际使用功率需低于额定功率的70%(即≤43.75mW),避免过热导致阻值漂移或封装损坏;若需更高功率,需选用0603或更大封装的0Ω电阻。

2. 焊接工艺规范

  • 回流焊温度曲线:峰值温度240℃~250℃,时间≤30秒;
  • 手工焊接:烙铁温度≤350℃,焊接时间≤3秒,避免损坏陶瓷基片。

3. 精度匹配建议

若需精密低阻抗(如电流检测电路),需确认实际寄生电阻是否满足需求(本产品±5%精度适合常规连接,精密场景建议选用激光微调0Ω电阻)。

本产品凭借小体积、宽温稳定、低阻抗的特性,成为高密度PCB设计中替代传统跳线的优选元件,覆盖从消费电子到工业控制的多场景需求,是BOURNS厚膜电阻系列中的经典基础款。

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.
