CGA0603X7R103J500JT 产品概述

本产品为 HRE(芯声) 系列贴片多层陶瓷电容(MLCC),型号 CGA0603X7R103J500JT。主要参数:容值 10 nF(103);精度 ±5%(J);额定电压 50 V(500);介质类型 X7R;封装 0603(1608 公制)。适用于对体积、成本和可靠性有综合要求的去耦、滤波与耦合类应用。

一、产品特点

  • 小型化封装 0603,便于高密度 PCB 布局,适合移动设备与消费电子。
  • X7R 二类介质,工作温度范围宽(-55°C ~ +125°C),在温度变化下电容稳定性良好,适合一般信号与电源去耦场合。
  • ±5% 容差,适用于对容值有中等精度要求的电路设计。
  • 额定耐压 50 V,可用于中低压电源旁路、滤波与耦合电路。

二、典型电气与环境参数

  • 容值:10 nF(103)
  • 容差:±5%(J)
  • 额定电压:50 V DC
  • 介质:X7R(温度系数)
  • 工作温度:通常 -55°C ~ +125°C(典型 X7R 规格)
  • 温度引起的容值变化:X7R 类陶瓷在规定温区内容值变化有限,但仍存在随温度及偏压而变化的特性,设计时应予以考虑。

三、应用场景

  • 电源去耦与旁路(DC-DC 输入/输出、微处理器供电旁路)
  • 高频滤波、射频旁路与阻抗匹配(低至中频段)
  • 信号耦合与时间常数电路(与电阻配合)
  • 消费电子、通讯设备、工业控制与便携设备等常见电子产品

四、封装与可靠性

  • 封装:0603(英制)小体积,适合自动贴装与高密度板面布置。
  • 机械应力敏感:贴装与回流焊接时应注意焊盘设计与 PCB 过孔位置,避免热挤压或机械应力集中导致裂纹。
  • 老化与偏压效应:X7R 为典型 II 类陶瓷,会随时间有缓慢的容量衰减,并且在直流偏压下容值会有所下降。对于高精度或关键电路,请在设计阶段进行实际工况下的验证或预留裕度。

五、工艺与使用建议

  • 回流焊:兼容无铅回流工艺,生产焊接建议按 IPC/JEDEC J-STD-020 类规范执行,回流峰值温度一般不超过 260°C。
  • 焊盘布局:采用合适的焊盘尺寸和过孔布局以减少应力传递,推荐合适的锡膏量与丝印定位。
  • 去应力设计:在器件两端留有一定铜箔缓冲或采用通孔/过孔分布,以降低热/机械应力。
  • 电气裕度:在对容值稳定性要求较高的设计中,考虑温度和偏压带来的容量变化,必要时选择更大容值或更高等级器件。

六、储存与注意事项

  • 存放环境:建议干燥、常温、避免阳光直射与腐蚀性气体。长时间暴露于高湿环境或经历多次温湿循环后,可按厂方建议进行回烘处理再入炉焊接。
  • 检验:入厂/量产前建议进行外观检查与抽样电容值测试,关键信号路径可进行性能验证。

七、订购与技术支持

型号:CGA0603X7R103J500JT(HRE/芯声)
在选型与批量采购前,建议向供应商索取详细数据手册与可靠性报告(温漂、偏压特性、寿命试验等),并在目标应用环境下进行样片评估和焊接工艺验证。

如需同系列不同电压、容值或更高可靠性(例如军用/汽车等级)的替代方案,可提供进一步的选型建议与比较。

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
