CGA1206X7R475K500NT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心参数与型号解析

CGA1206X7R475K500NT是HRE芯声推出的1206封装中压MLCC,型号各部分含义清晰:

  • CGA:芯声MLCC系列标识,代表工业级标准封装;
  • 1206:英制封装尺寸(对应公制3.2mm×1.6mm),适配小型化电路;
  • X7R:温度系数(-55℃~+125℃内电容变化≤±15%),兼顾稳定性与容值密度;
  • 475:容值编码(47×10⁵pF=4.7μF);
  • K:精度等级(±10%);
  • 500:额定电压(50V DC);
  • NT:尾缀(标准无铅封装,符合环保要求)。

关键参数汇总:容值4.7μF、精度±10%、额定电压50V、工作温度-55℃~+125℃、封装1206(3216公制)、无极性设计。

二、材料特性与性能优势

采用X7R高稳定陶瓷介质,结合多层叠层结构(陶瓷介质+银钯内电极+镍锡外电极),性能突出:

  1. 宽温稳定:-55℃~+125℃内电容漂移≤±15%,比Y5V等高介电材料更可靠,适配工业/汽车周边场景;
  2. 中压耐受:50V额定电压覆盖90%以上中低压电路(如5V/12V/24V电源系统);
  3. 小体积高密度:1206封装实现4.7μF容值,比传统铝电解电容体积缩小70%以上;
  4. 低损耗:1kHz/25℃下损耗角正切值(tanδ)≤0.015,不影响信号完整性;
  5. 环保无铅:符合RoHS 2.0、REACH法规,不含铅、镉等有害物质,满足出口要求。

三、典型应用场景

该产品适配多领域电路的滤波、耦合、去耦需求:

  1. 消费电子:手机/平板的电源滤波(滤除直流纹波)、音频信号耦合、IC去耦(抑制电源噪声);
  2. 工业控制:PLC的IO口耦合电容、传感器信号滤波(温度/压力传感器)、电机驱动EMI抑制;
  3. 汽车电子:车载中控屏电源模块、行车记录仪信号处理、倒车雷达辅助电容(非安全关键件);
  4. 通信设备:路由器/交换机的电源滤波、射频前端信号耦合;
  5. 医疗设备:家用血糖仪/血压计的电源滤波(低噪声要求)。

四、可靠性与质量保障

HRE芯声通过严格测试与体系认证,确保产品一致性:

  1. 可靠性测试:
    • 高温寿命:125℃/50V下1000小时,电容变化≤±10%,绝缘电阻≥10⁹Ω;
    • 温度循环:-55℃~+125℃循环1000次,无开裂、参数漂移;
    • 振动冲击:符合IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)标准;
  2. 质量体系:通过ISO 9001(质量管理)、ISO 14001(环境管理)认证,批量产品精度偏差控制在±8%以内(优于标称±10%)。

五、封装与焊接注意事项

  1. 封装尺寸:公制3.2mm×1.6mm×1.6mm,焊盘间距建议0.8~1.0mm;
  2. 焊接工艺:
    • 回流焊:预热区150180℃(60120s),回流区220~250℃(峰值≤255℃,时间≤30s);
    • 波峰焊:浸锡时间≤3s,温度≤245℃;
  3. 储存要求:未开封产品存于25℃±5℃、湿度≤60%环境,开封后168小时内焊接,受潮需105℃烘烤24小时;
  4. 静电防护:操作需佩戴防静电手环/手套,使用防静电工作台,避免静电损坏。

该产品凭借稳定的宽温性能、可靠的中压耐受能力及适配多场景的特点,成为中低压电路设计的优选MLCC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
