CGA1206X7R102K101KT多层陶瓷电容产品概述

一、产品基本属性与命名解析

CGA1206X7R102K101KT是HRE(芯声)品牌推出的通用型多层陶瓷电容(MLCC),核心定位为中低压宽温场景的稳定滤波/耦合元件。其命名遵循行业通用逻辑,各段含义清晰:

  • CGA:片式多层陶瓷电容的封装标识(Chip Capacitor Array简化);
  • 1206:英制封装尺寸(12mil×6mil),对应公制3.2mm×1.6mm;
  • X7R:温度系数代码,代表工作温度范围-55℃~+125℃,容值变化≤±15%;
  • 102:容值标识(10×10²pF=1nF);
  • K:精度等级(±10%);
  • 101:额定电压(10×10¹V=100V DC);
  • KT:HRE内部规格代码(含端电极结构、卷带包装等定制信息)。

二、核心电气性能参数

该产品围绕“宽温稳定、中压可靠”设计,关键参数符合工业级通用需求:

  1. 容值与精度:标称1nF,允许偏差±10%(K级),满足大多数滤波/去耦场景的容值要求;
  2. 额定电压:100V DC(直流),兼容≤100V交流电路(需降额使用);
  3. 温度特性:X7R介质的核心优势——-55℃至+125℃范围内,容值漂移≤±15%,避免极端温度下电路性能波动;
  4. 损耗与绝缘:1kHz测试频率下,损耗角正切(DF)≤2.5%(低损耗保证能量效率);25℃、100V DC条件下,绝缘电阻(IR)≥10⁴ MΩ,防止漏电流过大;
  5. 直流偏置特性:X7R介质受偏置影响容值下降,100V额定电压下下降率≤20%(选型需预留余量)。

三、封装与机械特性

采用1206标准片式封装,适配自动化贴装,机械可靠性满足量产需求:

  1. 尺寸规格:长3.20±0.2mm、宽1.60±0.2mm、厚1.60±0.2mm,符合IPC-J-STD-001标准;
  2. 端电极结构:三层复合电极(银基层+镍阻挡层+无铅锡层),兼容RoHS2.0,焊接后无剥离/开裂;
  3. 焊接适应性:回流焊峰值260℃±5℃(持续10s内),波峰焊245℃±5℃(持续5s内);
  4. 机械强度:抗弯强度≥100MPa,1.5m跌落测试后容值变化≤±5%,适配工业设备抗冲击需求。

四、典型应用场景

基于“宽温、中压、小体积”特性,该电容广泛用于以下领域:

  1. 电源滤波:DC-DC转换模块(如12V转5V、24V转12V)的输入/输出滤波,抑制纹波噪声;
  2. 芯片去耦:MCU、FPGA等数字芯片的电源去耦,提升电路抗干扰能力;
  3. 工业控制:PLC、传感器模块、伺服驱动器等,适配-40℃~+85℃工业环境;
  4. 消费电子:机顶盒、路由器、智能家居设备的电源部分,替代电解电容缩小体积;
  5. 低频耦合:音频信号、控制信号的耦合电路(1nF容值适配10kHz以下信号)。

五、可靠性与环境适应性

HRE对该产品完成多项行业级验证:

  1. 温度循环:-55℃(30min)→+125℃(30min)循环1000次,容值变化≤±10%,IR≥初始值80%;
  2. 湿热测试:85℃/85%RH环境1000小时,容值变化≤±10%,IR≥10³ MΩ;
  3. 寿命测试:100V DC、+125℃工作1000小时,无失效,容值变化≤±10%;
  4. 环保合规:符合RoHS2.0、REACH法规,无铅无镉,可出口欧盟/北美。

六、选型与使用注意事项

  1. 电压降额:直流电路建议按80%额定电压使用(≤80V),交流电路峰值电压≤70V,延长寿命;
  2. 偏置影响:若存在直流偏置(如电源并联),需计算容值下降率,必要时选更大容值;
  3. 贴装适配:1206封装适配0402以上贴片机,需确认设备精度;
  4. 替代选型:可替代村田GRM188R61C102KA01D、三星CL21B102KAFNNNE,注意端电极兼容性。

该产品以“高性价比+宽温稳定”为核心优势,覆盖通用电子、工业控制等多场景,是中低压电路的实用选型。

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
