CGA0603X5R225K500JT 贴片多层陶瓷电容(MLCC)产品概述

一、产品标识与基本定位

CGA0603X5R225K500JT是HRE芯声推出的0603封装通用型贴片多层陶瓷电容(MLCC),主打小型化、高可靠性与温度稳定性,适配多数消费电子、工业控制等场景的滤波、耦合需求。其型号标识各部分含义明确:

  • CGA:HRE芯声MLCC系列前缀;
  • 0603:英制封装尺寸(0.06英寸×0.03英寸,对应公制1608,即1.6mm×0.8mm);
  • X5R:温度系数(-55℃~+85℃,容值变化±15%);
  • 225:容值编码(22×10⁵ pF = 2.2μF);
  • K:精度等级(±10%);
  • 500:额定直流电压(50V DC);
  • JT:工艺/批次代码。

二、核心电气参数详解

1. 容值与精度

标称容值2.2μF,精度±10%,实际生产范围为1.98μF~2.42μF,满足90%以上通用电路的误差要求(如电源滤波、音频耦合无需更高精度)。

2. 额定电压与降额建议

额定直流电压50V,是产品核心电压指标。实际使用需注意降额:建议工作电压不超过40V(额定值的80%),可将高温下寿命提升数倍(电压与寿命成反比)。

3. 温度系数与稳定性

X5R温度特性优于Y5V等低价介质:

  • 工作温度:-55℃~+85℃;
  • 容值变化:±15%(相对于25℃);
    适合对容值稳定性敏感的电路(如时钟滤波、信号耦合)。

4. 其他关键参数

  • 绝缘电阻:≥10⁹Ω(25℃、50V DC下),保证直流隔离;
  • 损耗角正切:≤1%(1kHz下),高频损耗低,适配射频旁路;
  • 循环寿命:-55℃~+85℃循环1000次后,容值变化≤±10%。

三、封装与工艺特性

1. 0603封装优势

体积小巧(1.6mm×0.8mm×0.8mm),适配高密度PCB设计(如智能手机主板);无引线结构,表面贴装(SMT)兼容性好,适合自动化生产。

2. 叠层陶瓷工艺

采用陶瓷介质层与镍电极层交替叠压烧结而成,容值密度是独石电容的数倍,且无极性(无需区分正负极),使用更便捷。

3. 环保与可靠性

  • 无铅环保:符合RoHS 2.0、REACH标准;
  • 焊接可靠性:回流焊后剪切强度≥2N,抗PCB形变能力强;
  • 存储稳定性:常温(25℃、湿度≤60%)下存储1年,性能无衰减。

四、典型应用场景

该产品平衡了容值、电压与体积,广泛用于:

  1. 消费电子:手机/平板的DC-DC滤波、音频耦合、射频旁路;
  2. 工业控制:小型PLC、传感器节点的电源滤波(适配-55℃~+85℃环境);
  3. 通信设备:路由器、小型基站的电源滤波、中频耦合;
  4. 电源模块:开关电源输出滤波(配合小容值MLCC滤除高低频纹波);
  5. 汽车电子:车载娱乐系统、低功耗传感器滤波(需确认温度≤85℃)。

五、选型与使用注意事项

  1. 电压匹配:避免交流场景(MLCC为直流设计,交流下需额外降额);
  2. 温度限制:若环境温度超85℃,建议换X7R(-55℃~+125℃)或C0G(高精度);
  3. 焊接工艺:回流焊峰值温度230℃~245℃,时间≤30秒;波峰焊避免长时间浸泡;
  4. 静电防护:ESD阈值2kV,存储需防静电包装,焊接戴防静电手环。

该产品凭借高性价比与稳定性能,是中小功率电路滤波、耦合的优选元件。

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
