CGA1206C0G100J102MT 多层陶瓷电容器(MLCC)产品概述

一、产品核心身份与定位

CGA1206C0G100J102MT是HRE芯声推出的一款高频高压型多层陶瓷电容器(MLCC),属于该品牌CGA系列工业级通用型号。型号各部分含义明确:

  • 1206:英制贴片封装(对应公制3216,尺寸3.2mm×1.6mm);
  • C0G:温度系数代号(NP0类,IEC标准);
  • 100:标称容值(10pF,10×10⁰ pF);
  • J:精度等级(±5%);
  • 102:额定电压(10²=1000V DC)。

该产品聚焦“高频稳定性+高压耐受”双重需求,适配工业、医疗、通信等领域的中高压高频电路。

二、关键性能参数详解

1. 容值与精度

标称容值10pF,精度±5%(J档),实际生产中HRE采用高精度叠层工艺,容值偏差控制在±4%以内(优于标称),可满足振荡电路、滤波网络、匹配网络对容值一致性的要求,降低电路调试难度。

2. 温度系数(C0G/NP0)

C0G是MLCC中温度稳定性最优的材质之一,核心特性:

  • 温度系数≤±30ppm/℃,-55℃~125℃范围内容值变化≤±0.3%;
  • 1GHz频率下损耗角正切值(tanδ)≤0.001,远低于X7R材质(tanδ≈0.02),适合射频、微波电路。

3. 额定电压与耐压

直流额定电压1000V,交流额定电压约707V(有效值,正弦波)。产品通过1.5kV DC/1分钟耐压测试(行业标准),实际使用建议降额至80%额定电压(≤800V DC),避免过应力导致寿命衰减。

4. 封装与尺寸

1206贴片封装,具体参数:

  • 长3.2±0.2mm,宽1.6±0.2mm,厚0.5±0.1mm;
  • 引脚间距1.6mm,兼容西门子、富士等常规SMT贴片机,适合高密度PCB布局。

三、制造工艺与可靠性特点

HRE芯声采用低温共烧陶瓷(LTCC)叠层工艺,将C0G陶瓷介质与银钯合金电极交替叠层,烧结后形成一体化结构,核心优势:

  1. 介质均匀性:陶瓷介质层厚度一致性≤±5%,减少局部电场集中,提升耐压可靠性;
  2. 电极附着力:银钯电极与陶瓷结合强度≥10MPa,避免焊接或温度循环中脱落;
  3. 环保合规:符合RoHS 2.0、REACH SVHC标准,不含铅、镉等有害物质。

可靠性测试覆盖:

  • 高温高湿(85℃/85%RH,1000小时):容值变化≤±1%,绝缘电阻≥10¹⁰Ω;
  • 温度循环(-55℃~125℃,1000次):无开裂、引脚脱落;
  • 耐焊接热(260℃/10秒):封装无变形,性能无衰减。

四、典型应用场景

1. 工业高压电源

  • 开关电源高压滤波(DC-DC升压电路输出端);
  • EMI滤波网络(抑制共模/差模干扰,符合IEC 61000-4标准);
  • 变频器、伺服驱动器的高压耦合电容。

2. 医疗设备高压电路

  • X光机、高频电刀的高压耦合/去耦电容(容值稳定避免输出波形畸变);
  • 医用监护仪的高压隔离电路(满足IEC 60601医疗安全标准)。

3. 通信射频模块

  • 基站射频前端匹配网络(C0G低损耗提升信号传输效率);
  • 微波通信设备振荡电路(容值稳定保障频率精度);
  • 卫星通信终端高频滤波。

4. 测试测量仪器

  • 示波器高压探头分压电容(容值稳定保障测量精度);
  • 信号发生器高频振荡电容;
  • 耐压测试仪校准电容。

五、选型与替换注意事项

  1. 参数匹配优先级:

    • 必须一致:封装(1206)、温度系数(C0G)、额定电压(1kV);
    • 尽量一致:容值(10pF)、精度(±5%),避免用X7R/X5R替换(温度特性差)。
  2. 贴装工艺要求:

    • 回流焊曲线:预热150180℃(60秒)→ 恒温200220℃(120秒)→ 峰值240~260℃(≤10秒);
    • 禁止手工焊接(温度过高易损伤陶瓷介质)。
  3. 库存与采购:

    • 包装:1000pcs/盘,编带式包装(适配自动贴装);
    • 交期:常规订单12周,紧急订单可协调35天。

该产品凭借C0G材质的高频稳定性与1kV高压耐受能力,成为工业、医疗、通信领域中高压高频电路的高性价比选择,HRE芯声的成熟工艺保障了长期可靠性。

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
