CGA1206X7R475K160NT 片式多层陶瓷电容产品概述

一、产品命名与基本属性解析

CGA1206X7R475K160NT是HRE芯声推出的通用型片式多层陶瓷电容(MLCC),其命名规则直接对应核心参数与产品定位:

  • CGA:HRE芯声片式MLCC系列标识,代表多层陶瓷电容技术路线;
  • 1206:英制封装尺寸,对应公制3.2mm(长)×1.6mm(宽)×1.0mm(典型厚度),适配常规贴片焊接工艺;
  • X7R:温度系数代码,明确工作温度范围为-55℃~125℃,此范围内容量变化≤±15%;
  • 475:容值代码,计算方式为「47×10^5 pF」=4.7μF;
  • K:容值精度等级,代表±10%的误差范围;
  • 160:额定直流电压(DC),即产品可长期承受的最大电压为16V;
  • NT:HRE内部封装细节与批次标识,不影响核心性能参数。

二、核心电气性能参数

该产品围绕通用低电压场景优化,关键电气参数如下:

  1. 容值与精度:标称容值4.7μF,容差±10%,25℃标准温度下容值范围为4.23μF~5.17μF;
  2. 额定电压:直流16V,交流额定电压需结合频率计算(1kHz下典型值为10Vrms),实际使用需避免超额定值;
  3. 温度特性:X7R介质的温度稳定性表现为:-55℃25℃容量变化≤±10%,25℃125℃容量变化≤±15%,无明显容量漂移;
  4. 漏电流:25℃、额定电压下,漏电流≤4.7μF×16V×10^-6 =75.2μA,符合工业级通用MLCC要求;
  5. 损耗角正切(tanδ):1kHz下典型值≤2.5%,满足信号传输与滤波的损耗控制需求。

三、材料与工艺特点

HRE芯声针对该产品采用成熟MLCC工艺,核心材料与工艺优势包括:

  1. 陶瓷介质:选用高介电常数X7R基陶瓷,兼顾容量密度与温度稳定性,避免Y5V介质的温度漂移问题;
  2. 内电极:镍(Ni)基内电极,符合RoHS环保标准,提升电极与介质兼容性,减少老化效应;
  3. 外电极结构:三层复合电极(银层→镍层→锡层),确保焊接可靠性(通过J-STD-002测试),降低接触电阻;
  4. 叠层工艺:高精度叠层技术控制介质层厚度均匀性,提升容值一致性与产品良率;
  5. 封装防护:表面涂覆耐温环氧树脂,提升机械强度与抗潮湿能力,常温干燥环境下存储寿命≥12个月。

四、典型应用场景

因参数适配通用低电压电路,该产品广泛应用于:

  1. 消费电子:智能手机、平板的电源滤波(去除电池纹波噪声)、音频电路耦合(耳机接口信号隔离);
  2. 小型智能硬件:智能手表、无线耳机的射频前端去耦、传感器供电滤波;
  3. 家电与通信:遥控器、智能插座的电源滤波、WiFi模块信号去耦;
  4. 工业控制:小型PLC、传感器模块的低电压(≤12V)电源辅助滤波、信号调理电路耦合。

五、选型与使用注意事项

为确保可靠性,需注意以下要点:

  1. 电压余量:实际工作电压需低于额定电压的80%(建议≤12.8V),避免长期过压导致容量下降;
  2. 温度降额:环境温度接近125℃时,每升高10℃,电压降额10%;
  3. 焊接工艺:
    • 回流焊:温度曲线峰值≤245℃,时间≤10秒,避免热冲击开裂;
    • 手工焊:烙铁温度≤350℃,焊接时间≤3秒,防止局部过热;
  4. 机械应力:1206封装避免PCB弯曲(弯曲半径≥10mm)或外力撞击,防止电容开裂;
  5. 存储条件:存储于25℃±5℃、湿度≤60%环境,开封后1个月内使用完毕,避免受潮影响焊接。

该产品以高性价比、稳定的温度特性适配多数通用低电压电路,是消费电子、智能硬件领域的常用选型之一。

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
