SC0402J0000I2ANRH 贴片电阻产品概述

SC0402J0000I2ANRH是信维通信(Sunway)推出的一款0402封装0Ω厚膜贴片电阻,主打小体积、高可靠性,适用于多种电子设备的电路短接、电流检测及调试预留等场景,是无源元件中替代导线的实用选择。

一、产品基本定位

该电阻采用厚膜工艺制造,核心功能为电路低阻连接/短接,替代传统导线或跳线,同时具备一定功率承载能力与温度稳定性。其0402封装(英制尺寸,对应公制1005:长1.0mm×宽0.5mm)适配高密度PCB布线,尤其适合消费电子、工业控制等对体积敏感的领域。

二、核心性能参数详解

1. 阻值与精度

标称阻值为0Ω(实际存在毫欧级微小阻值,因工艺限制),精度为**±5%**——实际阻值与标称值偏差不超过5%,满足常规短接、低阻检测的精度需求。

2. 功率承载能力

额定功率为62.5mW,指工作温度范围内可长期稳定承载的最大功率耗散。若实际功率超限,可能导致电阻升温、阻值漂移甚至熔断。

3. 温度系数

温度系数为**±300ppm/℃**,表示每变化1℃,阻值相对变化0.03%(300ppm=0.03%),确保宽温下的阻值稳定性,适合高低温交替环境。

4. 工作温度范围

支持**-55℃+155℃**宽温工作,覆盖工业级(-40℃+85℃)及部分高温场景,可满足户外设备、车载辅助系统等需求。

三、封装与物理特性

1. 0402封装优势

  • 尺寸:长1.0mm×宽0.5mm×高0.35mm(典型值),体积小巧,适配高密度PCB;
  • 焊接兼容性:两端电极设计,兼容回流焊(260℃)、波峰焊工艺;
  • 环保性:符合RoHS 2.0及REACH标准,无铅无卤,满足绿色制造要求。

2. 厚膜工艺特点

采用陶瓷基底+丝网印刷电阻层工艺,相比薄膜电阻成本更低,相比绕线电阻体积更小,抗机械应力、抗潮湿性能优异。

四、典型应用场景

该电阻的0Ω特性与小体积使其在多场景发挥作用:

  1. 电路跨接:替代导线实现PCB多层板、不同区域短接,简化布线;
  2. 小电流检测:利用毫欧级实际阻值,配合运放实现微安级电流检测(需匹配功率);
  3. 调试预留:电路设计预留0Ω位置,后期可替换为合适阻值电阻,灵活调整参数;
  4. 低功率保险丝:小功率(≤62.5mW)电路中,过载时熔断起到临时保护;
  5. 射频匹配:高速/射频电路中,0Ω电阻短接路径比导线更稳定,减少信号反射。

五、可靠性与质量保障

信维通信对该产品进行多项可靠性测试:

  • 回流焊测试:260℃回流焊后无开裂、阻值漂移;
  • 温度循环:-55℃~+155℃循环500次,阻值变化≤1%;
  • 湿度测试:85℃/85%RH环境1000小时,阻值变化≤2%;
  • 质量认证:通过ISO 9001体系认证,批量供应一致性良好。

六、适用领域

SC0402J0000I2ANRH广泛适用于:

  • 消费电子:智能手机、平板主板布线;
  • 工业控制:PLC、传感器模块信号短接;
  • 通信设备:路由器、基站射频电路匹配;
  • 汽车电子:车载显示屏、辅助控制系统低功率电路。

总结:该产品以小体积、宽温特性、稳定厚膜工艺为核心优势,是电子设计中替代导线、实现灵活短接的实用选择,适合对成本与可靠性均有要求的批量应用场景。

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
