核心参数汇总:

参数 数值 容值 470nF(±10%) 额定电压 10V DC 温度特性 X5R(-55℃~+85℃,ΔC/C±15%) 封装 002(英制)/0603(公制) 品牌 HRE芯声

二、关键性能特性

  1. 宽温稳定的容值表现
    X5R介质使产品在-55℃至+85℃范围内容值变化控制在±15%以内,无需额外补偿电路,适配户外、车载等宽温场景(非汽车级但满足消费电子宽温需求)。

  2. 小体积高密度集成
    002封装(公制0603)尺寸紧凑(1.6mm×0.8mm×0.5mm),适合PCB空间受限的小型化设备,支持高密度贴装,提升电路集成度。

  3. 低压场景全覆盖
    10V额定电压覆盖主流低压系统(5V/3.3V/1.8V),满足电源滤波、信号耦合、去耦等基础功能,适配多数消费电子、物联网终端。

  4. 高精度与一致性
    ±10%容值精度确保批量产品性能一致,减少电路调试难度,提升终端产品可靠性(如批量生产的耳机、传感器节点)。

  5. 无极性易贴装
    无正负极性,可正反贴装,适配自动化SMT生产线,生产效率高,降低人工成本。

三、典型应用场景

CGA002X5R474K100GT因体积小、性能稳定,广泛应用于:

  1. 消费电子终端:智能手机/平板的音频电路耦合、电源模块去耦;智能手环/手表的传感器信号调理;
  2. 物联网(IoT)设备:智能家居温湿度传感器的电源滤波;智能门锁的低功耗电路去耦;
  3. 小型电子模块:蓝牙耳机/TWS耳机的充电电路滤波;便携式移动电源的电压稳定;
  4. 工业辅助电路:小型PLC模块的信号隔离耦合;低功耗工业传感器的电源调节。

四、品牌与可靠性保障

HRE芯声作为国内专业MLCC制造商,CGA系列产品具备可靠品质:

  1. 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,满足绿色电子设计;
  2. 可靠性测试:经过高低温循环(-55℃+85℃,1000次)、湿度老化(85℃/85%RH,1000h)、振动测试(102000Hz,1g),故障率低于行业平均;
  3. 一致性管控:采用先进陶瓷介质制备与叠层工艺,批量产品容值、损耗等参数波动≤5%;
  4. 售后支持:提供完整datasheet、应用指导,批量客户可定制参数验证服务。

五、封装尺寸与焊接要求

  1. 封装尺寸(公制):
    • 长度(L):1.6±0.1mm
    • 宽度(W):0.8±0.1mm
    • 厚度(T):0.5±0.1mm
    • 引脚间距(S):0.4±0.1mm
  2. 焊接要求:
    • 优先回流焊,温度曲线符合IPC/J-STD-020(峰值240260℃,回流时间3060s);
    • 禁止手工焊(易过热损坏),返修需用热风枪(温度≤260℃,时间≤10s);
    • PCB焊盘推荐尺寸:长1.21.4mm,宽0.50.6mm。

六、选型与使用注意事项

  1. 电压降额:实际工作电压≤额定电压的80%(即≤8V),避免过压击穿;
  2. 温度限制:工作环境不得超出-55℃~+85℃,否则容值漂移影响电路性能;
  3. 静电防护:ESD阈值2kV,操作需戴防静电手环,使用防静电工具;
  4. 存储条件:未开封产品存于25±5℃、40%~60%湿度环境,开封后12个月内用完;
  5. 机械应力:贴装后PCB弯曲半径≥10mm,防止电容开裂。

本产品是低压小型化电路的高性价比选择,平衡了容量、体积与可靠性,适配多数通用电子场景。

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
