CGA0603X7R472K500JT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性

CGA0603X7R472K500JT是HRE芯声推出的0603封装贴片多层陶瓷电容(MLCC),属于通用型表面贴装元件,核心用于电子电路的滤波、耦合、旁路及信号去耦,符合RoHS 2.0、REACH环保标准,无铅无卤设计,适配各类自动化贴装产线。

二、核心电气与物理参数

该产品的关键参数清晰明确,直接支撑电路设计选型:

  1. 容值与精度:标称容值4.7nF(容值代码“472”,即47×10²pF),精度±10%(误差代码“K”),满足大多数民用及工业级电路的容值需求;
  2. 额定电压:直流50V(DC),适用于低中压电路(如12V/24V电源系统);
  3. 温度系数:X7R(行业通用中温稳定介质),-55℃~+125℃范围内容值变化≤±15%;
  4. 封装尺寸:0603英制封装(公制1.60mm×0.80mm×0.80mm),厚度公差±0.10mm,体积小巧适配高密度PCB设计;
  5. 电极结构:端电极采用“银-镍-锡”三层复合设计,焊接兼容性强,可耐受回流焊(260℃峰值10秒)、波峰焊工艺。

三、X7R陶瓷材料特性

X7R是MLCC领域应用最广泛的介质之一,其特性直接决定产品的适用场景:

  • 温度稳定性:覆盖工业级低温(-55℃)至汽车级高温(+125℃),容值漂移远优于Y5V等低稳定介质,适合对容值变化敏感的滤波电路;
  • 介电常数:约2000~3000,可在0603小封装内实现4.7nF容值,平衡小型化与性能;
  • 电压响应:在50V额定电压下,容值变化≤±10%,无明显“电压降容”现象(对比高介电常数介质更稳定);
  • 成本优势:相比NP0等超稳定介质,性价比更高,适合量产型电子设备。

四、典型应用场景

因尺寸小、性能稳定,该产品广泛覆盖以下领域:

  1. 消费电子:智能手机、平板的电源滤波(如电池管理系统BMS旁路)、音频电路耦合;
  2. 汽车电子:车载中控、ADAS传感器(如毫米波雷达)的信号去耦、CAN总线噪声抑制(需确认批次是否满足AEC-Q200);
  3. 工业控制:PLC、伺服驱动器的电源滤波、模拟信号耦合;
  4. 通信设备:路由器、交换机的低频频段滤波、电源模块去耦;
  5. 智能家居:智能音箱、安防摄像头的电源及信号电路。

五、可靠性与品质保障

HRE芯声作为国产MLCC优势品牌,该产品通过多项行业标准测试:

  • 焊接可靠性:符合J-STD-020回流焊标准,无“立碑”“虚焊”等缺陷;
  • 寿命测试:125℃+50V DC负载下,寿命≥1000小时(IEC 60384-14标准);
  • 环境适应性:通过-55℃~+125℃温度循环(1000次)、85℃/85%RH湿热测试(1000小时);
  • 品质认证:ISO 9001质量管理体系认证,部分批次可提供AEC-Q200汽车级报告。

六、选型参考与注意事项

  1. 选型匹配:若需更高容值(如10nF)选同系列CGA0603X7R103K500JT;若需超稳定容值(如NP0)选CGA0603NP0102J100JT(注意电压降额);
  2. 电压降额:实际应用建议电压≤40V(额定电压80%),延长寿命;
  3. 存储条件:常温(25℃±5℃)、湿度≤60%,未开封存储期≤12个月;
  4. 焊接工艺:避免局部过热(如烙铁直接接触电容),推荐回流焊温度曲线(升温速率≤3℃/s)。

该产品以高性价比、稳定性能成为0603封装MLCC的主流选型之一,适配多数电子设备的常规电路需求。

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
