CGA1206X7R223K631NT 贴片多层陶瓷电容(MLCC)产品概述

CGA1206X7R223K631NT是HRE芯声电子推出的一款中高压贴片多层陶瓷电容(MLCC),专为需要稳定容值、耐受高压及宽温环境的电子电路设计,核心参数匹配工业级、医疗级及高频电源等场景的性能需求。

一、产品基本身份与应用定位

该型号属于HRE芯声高压MLCC系列,采用1206标准贴片封装,聚焦630V中高压电路的滤波、耦合、旁路及储能等核心功能,替代传统体积更大的电解电容或插件电容,助力电路小型化、集成化设计。其温度特性与电压稳定性,使其在温度波动较大的工业现场、医疗设备及通信基站等场景中表现可靠。

二、核心电气与物理参数解析

2.1 电气参数

  • 容值与精度:标称容值22nF(即22×10³pF,型号中“223”为容值代码),精度±10%(型号中“K”为精度代码),满足多数工业电路对容值偏差的设计要求;
  • 额定电压:630V DC(型号中“631”为电压代码,63×10¹=630V),是该产品的核心高压耐受指标;
  • 温度系数:X7R(型号中“X7R”为介质代码),对应温度范围-55℃~+125℃,容值变化率≤±15%,属于中温稳定型陶瓷介质,比Y5V等低稳定介质更适合温度变化场景;
  • 频率特性:MLCC结构天然具备高频低损耗特性,22nF容值在kHz~MHz频段内阻抗特性稳定,适合高频滤波与耦合。

2.2 物理参数

  • 封装尺寸:1206英制封装(公制3216,长3.2mm×宽1.6mm×高约1.2mm),符合主流贴片生产设备的贴装规范;
  • 电极材料:采用环保无铅镍电极(Ni)+锡镀层,符合RoHS 2.0及REACH环保标准;
  • 介质材料:X7R型钛酸钡基陶瓷介质,兼顾容值稳定性与电压耐受能力。

三、封装与工艺特性

该产品采用多层陶瓷叠层工艺:将陶瓷介质层与电极层交替叠合,经高温烧结后形成一体化结构,相比单层电容,相同体积下容值更高、耐电压更强。1206封装的设计优势在于:

  • 体积紧凑:适合高密度PCB布局,降低电路整体尺寸;
  • 贴装兼容性:引脚间距与焊盘尺寸匹配常规贴片工艺,回流焊良率高;
  • 机械强度:陶瓷结构抗振动、抗冲击能力优于电解电容,适合车载、工业振动环境。

四、可靠性与环境适应性

  1. 温度可靠性:在-55℃~+125℃范围内长期工作,容值漂移控制在±15%以内,满足工业级温度要求;
  2. 电压可靠性:额定电压下连续工作1000小时以上无失效,过压测试(1.5倍额定电压)符合IEC 60384-1标准;
  3. 环境适应性:耐湿度(85℃/85%RH环境下1000小时容值变化≤5%)、抗盐雾(符合JESD22-A101标准),适合沿海或潮湿工业环境;
  4. 环保性:无铅无镉,符合欧盟RoHS指令及中国电子信息产品污染控制标准。

五、典型应用场景

该型号因高压耐受、宽温稳定及体积优势,广泛应用于:

  • 开关电源(SMPS):高压侧滤波、PFC电路耦合电容;
  • LED驱动电源:高压输出滤波、EMI抑制;
  • 工业控制电路:PLC模块、伺服驱动器的信号耦合与旁路;
  • 医疗设备:监护仪、呼吸机等高压电路的滤波(需满足医疗级可靠性);
  • 通信基站:射频模块的辅助滤波、电源模块高压滤波。

六、选型与使用注意事项

  1. 电压降额:工业环境建议按额定电压的50%70%使用(即≤315V441V),避免过压导致介质击穿;
  2. 焊接工艺:回流焊温度峰值≤245℃(持续时间≤10秒),波峰焊温度≤260℃(持续时间≤5秒),避免高温损坏陶瓷介质;
  3. 机械应力:焊接后避免PCB过度弯折,贴装时勿施加过大压力;
  4. 存储条件:常温干燥环境存储(温度≤30℃,湿度≤60%),开封后建议1年内使用完毕。

综上,CGA1206X7R223K631NT凭借630V高压耐受、X7R宽温稳定及1206小封装优势,成为中高压电路小型化设计的可靠选择,适用于工业、医疗、通信等多领域的高性能需求。

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
