SC0402J3R30G2ANRH 贴片厚膜电阻产品概述

SC0402J3R30G2ANRH是信维通信(Sunway)推出的一款小型化贴片厚膜电阻,凭借紧凑的0402封装、稳定的电气性能及宽温适应性,广泛应用于消费电子、物联网、工业控制等领域的电路阻抗匹配、信号调理及电流传感等场景。

一、产品基本信息

  1. 品牌与型号定义:由国内射频与精密元器件龙头企业信维通信研发生产,型号中“SC”为品牌标识,“0402”对应英制封装尺寸(公制1.0mm×0.5mm),“J”代表精度±5%,“3R30”明确标称阻值3.3Ω,“G2”关联温度系数与功率规格,“ANRH”为封装及工艺代码。
  2. 电阻类型:采用厚膜工艺制造——通过在氧化铝陶瓷基片上印刷电阻浆料、烧结固化而成,兼具成本优势与性能稳定性。
  3. 封装规格:0402贴片封装,体积小巧(仅1.0mm×0.5mm),适配高密度PCB设计,可有效降低设备整体尺寸与重量。

二、核心电气参数详解

该电阻的电气参数经过严格校准,可满足多数常规电路的性能需求:

  1. 阻值与精度:标称阻值3.3Ω,精度±5%,实际阻值范围为3.135Ω~3.465Ω,适用于非超高精度要求的阻抗匹配、分压及电流传感电路。
  2. 额定功率:25℃环境下额定功率为62.5mW,实际应用需结合工作温度降额(如125℃时功率需降至31.25mW),避免电阻过热失效。
  3. 最大工作电压:直流/交流最大工作电压50V,需注意电压与功率的匹配关系(50V下理论功率约757.6mW,远大于额定值,实际工作电压需限制在14.4V以内)。
  4. 温度系数:±200ppm/℃,表示每变化1℃,阻值变化为标称值的0.02%。例如125℃时,阻值变化量约0.066Ω,可满足一般温度波动下的电路稳定性。

三、典型应用场景

SC0402J3R30G2ANRH的小封装与稳定性能,使其适配以下场景:

  1. 消费电子:智能手机、平板电脑的射频前端匹配电路(小封装适配高密度PCB)、智能穿戴设备(蓝牙耳机、智能手环)的电源滤波与信号调理电路(低阻值实现高效电流传感)。
  2. 物联网模块:低功耗物联网节点的传感器接口电路(宽温适应性满足户外部署)、无线通信模块的阻抗匹配网络(3.3Ω阻值适配射频信号传输)。
  3. 小型电源电路:DC-DC转换器的反馈电阻、线性稳压器的负载电阻(额定功率适配低功耗电源设计)。
  4. 工业控制:小型工业传感器的信号调理电路(-55℃~155℃宽温范围适配极端环境)、小型电机驱动电路的限流电阻。

四、环境适应性与可靠性

该电阻具备优异的环境可靠性:

  1. 宽温工作范围:-55℃~+155℃的温度覆盖从低温户外到高温工业设备内部的多数场景,无需额外温度补偿。
  2. 机械稳定性:厚膜工艺的电阻膜层附着力强,抗冲击与振动性能良好,可适应运输振动及设备日常机械应力。
  3. 批量一致性:厚膜工艺参数离散性小,批量生产时阻值、功率一致性高,适合大规模自动化生产与组装。

五、选型与应用注意事项

  1. 功率降额:实际工作功率需随温度调整,避免超过额定值导致老化失效。
  2. 电压匹配:需同时考虑电压与功率限制,避免电压过高超出功率阈值。
  3. 焊接要求:采用回流焊工艺,注意焊接温度(230℃~260℃)与时间(峰值温度持续时间≤10s),避免损坏膜层。
  4. 精度需求:若场景精度要求高于±5%,需选用更高精度等级(如±1%)的电阻。

SC0402J3R30G2ANRH通过平衡性能、成本与尺寸,成为消费电子、物联网等领域小型化电路设计的理想选择,可有效提升设备集成度与可靠性。

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
