HRE芯声CGA0603X7R103K251JT多层陶瓷电容器(MLCC)产品概述

一、产品基本参数与型号解码

CGA0603X7R103K251JT是HRE芯声推出的通用型多层陶瓷电容器,型号各段含义清晰:

  • CGA:HRE芯声MLCC系列代号;
  • 0603:英制表面贴装封装(对应公制1608,尺寸≈1.5mm×0.8mm);
  • X7R:温度系数代码(-55℃~125℃,容值变化≤±15%);
  • 103:容值标识(10×10³pF=10nF);
  • K:容值精度(±10%);
  • 251:额定电压(25×10¹V=250V);
  • JT:端接与包装细节(无铅锡端接,8mm编带包装)。

核心参数表如下:

参数项 规格值 说明 封装类型 0603(英制)/1608(公制) 表面贴装,尺寸1.5×0.8mm 容值 10nF(103) 10×10³ pF = 10nF 容值精度 ±10%(K级) 通用场景标准精度 额定电压 250V(直流/交流) 251标识换算值 温度系数 X7R -55℃~125℃,ΔC/C≤±15% 端接类型 无铅锡(Sn) 符合RoHS 2.0标准 介电损耗 tanδ≤0.015@1kHz 低损耗,信号衰减小

二、核心性能与优势

  1. 宽温区容量稳定性:X7R介质特性解决了普通陶瓷电容温漂大的问题,在-55℃至+125℃范围内容值波动不超过±15%,适合工业、车载(通用场景)等温度波动大的环境;
  2. 中高压适配性:250V额定电压覆盖多数中低压电路需求,避免因电压不足导致击穿,适配开关电源、DC-DC转换器等功率电路;
  3. 小体积高密度集成:0603封装体积仅约1.5mm×0.8mm,可大幅节省PCB空间,满足智能手机、智能穿戴等紧凑产品的集成要求;
  4. 高可靠性:多层陶瓷结构无极性,抗电磁干扰(EMI)能力强,介电损耗低,长期工作失效率低于0.1%/1000小时;
  5. 环保合规:端接采用无铅锡,符合RoHS 2.0、REACH标准,适配全球绿色产品市场。

三、典型应用场景

  1. 电源滤波电路:开关电源输入/输出端、DC-DC转换器稳压模块中,滤除高频纹波,提升输出电压精度(如智能家电控制板的12V电源滤波);
  2. 信号耦合与去耦:通信设备(路由器、交换机)射频链路中耦合信号,工业PLC模拟量输入电路中滤除EMI干扰,防止传感器信号误判;
  3. 工业控制电路:伺服驱动器、变频器控制回路中,适应-40℃至+85℃的工业环境,保障控制信号稳定;
  4. 消费电子辅助电路:智能手机充电电路、智能音箱音频滤波电路中,小体积适配紧凑空间,提升音频纯净度;
  5. 车载通用场景:车载中控辅助电源、仪表盘显示驱动电路中,满足车载环境的温度与振动要求(非车规级,需确认具体项目资质)。

四、设计与选型注意事项

  1. 电压降额:实际工作电压建议≤200V(额定电压80%),避免介电损耗增加导致老化加速;
  2. 温度限制:工作温度需控制在-55℃~+125℃内,超过125℃容值下降可能超规格;
  3. 焊接工艺:0603封装需采用回流焊,温度曲线要求:预热区(150-180℃)60-120s,峰值温度≤245℃,升温/冷却速率≤3℃/s,避免陶瓷层开裂;
  4. 容值余量:±10%精度需预留10%-15%容值余量,确保极端条件下性能达标;
  5. 存储运输:存储温度-10℃~+40℃、湿度≤60%,避免高湿环境导致端接氧化。

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
