CGA0402X7R103J500GT 产品概述

一、产品概述

CGA0402X7R103J500GT(HRE/芯声)为贴片多层陶瓷电容(MLCC),标称容值10nF(103)、精度±5%(J)、额定直流电压50V、介质材料X7R、封装规格0402(约1.0mm × 0.5mm)。该产品以体积小、稳定性良好、适配自动化贴装工艺为特点,适用于各种中高密度电路板的去耦、滤波及旁路应用。

二、主要性能特点

  • 小型封装:0402尺寸适合高密度、微型化设计,节省PCB空间。
  • X7R介质:温度范围广(-55°C ~ +125°C),在规定温度范围内容量变化通常不超过±15%,适合一般去耦与滤波场合。
  • 耐压与精度:额定电压50V、容值公差±5%,满足中等电压轨及较严格容差要求。
  • 良好工艺兼容性:适配回流焊工艺,适合自动贴装与回流焊接生产线,可靠性高、性能稳定。

三、典型应用场景

  • 电源去耦与稳压电源旁路(DC-DC、LDO 输入/输出滤波)
  • 高频滤波与信号完整性优化(射频前端除外需注意介质特性)
  • 模拟电路耦合/退耦、采样与参考电压滤波
  • 移动终端、物联网设备、消费电子、工业控制等对体积与性能有平衡要求的产品

四、设计与使用建议

  • DC偏压效应:X7R为II类介质,工作偏压下会产生容量下降,尤其在高电压与大尺寸器件上更明显。对关键电容值的电路(如定时、滤波要求严格处)应进行实际电压下评估或适度冗余/降额设计。
  • 温度影响:在高低温环境下容量会随温度变化,建议核对系统工作温度对滤波/去耦需求的影响。
  • 焊接工艺:兼容主流回流焊工艺,最大回流峰值温度通常不超过260°C;严格遵循厂商焊接与回流曲线以避免裂纹或性能退化。
  • 机械应力:0402等小尺寸陶瓷电容易受PCB弯曲或焊接冷却不当引发微裂纹,布线布板时避免在器件附近开大过孔或槽并控制板形变,贴装时注意吸嘴压力与放置精度。
  • PCB封装建议:为获得良好焊接可靠性,建议参考器件数据手册中的推荐焊盘尺寸与焊膏厚度,不同厂商略有差异。

五、封装与订购信息

  • 标称型号:CGA0402X7R103J500GT(HRE/芯声)
  • 容值/精度/电压:10nF ±5% / 50V
  • 介质:X7R;封装:0402(约1.0 × 0.5 mm)
  • 包装方式:常见为卷带(Tape & Reel),便于SMT贴装;具体包装与最小起订量请参照供应商或经销商信息。
  • 合规性:常见符合RoHS等环保要求,采购时请确认相关合规证书与检测报告。

六、可靠性与质量控制

推荐在样片阶段完成温度循环、振动、湿热和回流焊后的电容值与绝缘电阻检测,以评估在目标工作环境下的长期可靠性。对于关键电路,建议做工况下的寿命与电容随时间变化测试,确保替代或量产时性能稳定。

总结:CGA0402X7R103J500GT 为小型通用型 MLCC,适合追求尺寸与性能平衡的场景。在高偏压或对容量稳定性要求极高的场合,应结合DC偏压与温度特性进行评估并做必要的电路冗余或降额设计。购买与设计前,建议索取并确认厂方数据手册与推荐布局图。

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
