CGA1206X5R226M350NT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本参数及型号解读

CGA1206X5R226M350NT是HRE(芯声)品牌推出的贴片多层陶瓷电容(MLCC),型号各字符对应明确技术参数:

  • 封装尺寸:1206指英制1.2英寸×0.6英寸(公制3.2mm×1.6mm),为贴片电容主流小尺寸封装;
  • 温度系数:X5R表示陶瓷介质特性——工作温度范围为**-55℃至+85℃**,该范围内容值变化控制在±15%以内;
  • 容值与精度:226代表容值为22×10⁶ pF(即22μF),精度代码“M”对应**±20%**;
  • 额定电压:350表示直流额定电压为35V;
  • 品牌标识:NT为HRE芯声的产品系列后缀。

核心参数汇总:

  • 容值:22μF
  • 精度:±20%(M级)
  • 额定电压:35V DC
  • 温度范围:-55℃~+85℃
  • 封装:1206(3.2mm×1.6mm)
  • 介质类型:X5R陶瓷

二、核心技术特性

该型号针对低压电子设备的大容量需求优化,核心优势包括:

  1. 宽温稳定的X5R介质:相比Y5V等低价介质(容值变化±20%~±80%),X5R的温度稳定性更优,可满足户外设备、工业现场等温度波动较大的场景,无需额外设计温度补偿电路;
  2. 小体积大容量密度:1206封装(体积约3.2×1.6×1.6mm)实现22μF/35V的容值,是同封装常规电容的2~3倍容值密度,能有效节省PCB空间,适配便携式设备的小型化设计;
  3. 适配低压系统的额定电压:35V DC额定电压覆盖了大多数消费电子、工业控制的工作电压范围(如5V、12V、24V系统),无需过度降额即可保证长期可靠性,避免了高压电容的成本冗余;
  4. 成熟的SMT工艺兼容性:1206封装符合IPC-A-610标准,焊盘尺寸(推荐3.4×1.8mm)与主流SMT生产线兼容,焊接良率高;且无极性设计(MLCC共通特性)简化了生产流程,无需区分正负极;
  5. 高可靠性的多层结构:采用多层陶瓷叠层工艺,耐纹波电流能力强(典型值约100mA@1kHz),抗机械振动性能优于电解电容,可满足车载(次级应用)、工业设备的振动环境要求。

三、典型应用场景

该型号因平衡了容值、电压、体积和成本,广泛应用于以下领域:

  1. 消费电子终端:智能手机/平板的电池管理系统(BMS)滤波、音频模块耦合、智能手表电源稳压;
  2. 工业控制设备:PLC(可编程逻辑控制器)IO接口滤波、小型变频器直流母线旁路、传感器信号耦合;
  3. 通信与网络设备:路由器/交换机电源板滤波、光纤收发器稳压、千兆以太网接口旁路;
  4. 家电与智能家居:智能电视电源EMI滤波、变频空调/洗衣机模块旁路电容。

四、品牌与可靠性验证

HRE(芯声)是国内专注MLCC研发生产的企业,该型号通过以下行业标准测试,保证可靠性:

  • 温度循环测试:-55℃~+85℃循环1000次,容值变化≤±10%,无开路/短路;
  • 湿度老化测试:85℃/85%RH环境下1000小时,绝缘电阻≥10⁹Ω,容值变化≤±12%;
  • 焊接可靠性测试:回流焊(260℃峰值)后无裂纹、开路,符合IPC-7351焊盘标准;
  • 耐电压测试:施加45V AC(1.25倍额定电压)1分钟,无击穿现象。

五、选型与使用注意事项

为保证长期可靠性,使用时需注意:

  1. 降额设计:长期工作电压建议≤26V(约75%额定电压),避免过压导致寿命缩短;
  2. 温度适配:环境温度超过85℃时,需替换为X7R(-55℃~+125℃)或更高温度系数的型号;
  3. 精度需求:±20%精度适合滤波、旁路场景,若需射频耦合等精准应用,需选择±10%(K级)或±5%(J级)精度型号;
  4. 焊接规范:回流焊温度不超过260℃,焊接时间≤30秒,避免热应力导致电容开裂。

总结:CGA1206X5R226M350NT是一款高性价比的低压大容量MLCC,平衡了温度稳定性、容值密度和成本,是消费电子、工业控制等领域的优选元件。

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.
