基础参数汇总:

参数项 规格值 封装类型 1206(SMT表面贴装) 标称容值 1μF(105 pF) 容值精度 ±10% 额定电压 50V DC 温度系数 X7R 工作温度范围 -55℃ ~ +125℃

二、核心材料与特性优势

该产品采用X7R型多层陶瓷介质,是MLCC中平衡容值稳定性与温度适应性的主流方案:

  1. 温度稳定性优异:在-55℃至+125℃范围内,容值变化率≤±15%,远优于Y5V等低成本材料(ΔC/C可达±20%~-80%);
  2. 电气性能均衡:兼顾1μF中等容值、50V中高压与低损耗,适配电源滤波、信号耦合等核心场景;
  3. 结构可靠性高:多层叠层结构(10~20层)提升容值密度,同时降低寄生电感,满足高频电路需求;
  4. 汽车级适配性:后缀“ACAUTO”表明产品通过汽车电子严苛测试,可用于车载动力、信息系统等场景。

三、封装与机械性能

1206封装是电子行业通用小尺寸贴装封装,机械性能符合KEMET与行业标准:

  • 物理尺寸:长3.2±0.2mm,宽1.6±0.2mm,典型厚度1.2±0.1mm;
  • 焊接兼容性:支持回流焊(260℃/10s峰值温度)、波峰焊(240℃/5s),焊盘适配标准SMT产线;
  • 机械强度:抗弯强度≥150MPa,可承受0.3mm以下基板弯曲;
  • 贴装效率:自动贴装精度±0.1mm,适合高速SMT生产(产能≥10k pcs/h)。

四、关键电气性能指标

  1. 电压与工作范围:直流额定电压50V,工作电压0~50V DC(交流应用需降额至70%以下);
  2. 容值稳定性:25℃/1kHz下容值1μF±10%,-55℃时ΔC/C≤+10%,+125℃时ΔC/C≤-15%;
  3. 损耗与ESR:1kHz下损耗角正切(tanδ)≤0.02,等效串联电阻(ESR)≤15mΩ(典型值),适合高频去耦;
  4. 绝缘性能:25℃/50V DC下绝缘电阻(IR)≥100GΩ·μF,+125℃时IR≥10GΩ·μF,确保长寿命可靠性。

五、典型应用场景

该产品因均衡性能与汽车级认证,广泛覆盖以下领域:

  1. 汽车电子:车载信息娱乐(IVI)电源滤波、动力总成ECU传感器耦合、车身控制模块(BCM)去耦;
  2. 工业控制:PLC输入输出模块、伺服驱动器电源滤波、机器人关节传感器电路;
  3. 消费电子:智能手机DC-DC转换器输出滤波、音频信号耦合、无线充电模块去耦;
  4. 通信设备:基站射频单元电源、路由器交换芯片去耦、光模块信号滤波;
  5. 医疗设备:低噪声监护仪电源滤波、便携式医疗仪器耦合电路(符合RoHS标准)。

六、可靠性与环境适应性

KEMET该型号满足多项严苛测试,确保恶劣环境下稳定工作:

  • 汽车级认证:符合AEC-Q200 Rev.E(汽车电子组件可靠性规范);
  • 温度循环:-55℃~+125℃循环1000次,容值变化≤±5%;
  • 湿度测试:85℃/85%RH环境1000h,IR衰减≤30%;
  • 机械测试:振动(20~2000Hz,10g加速度)100h无失效,冲击(1000g,0.5ms)5次无结构损坏;
  • 长寿命:额定电压+125℃下工作10000h,容值变化≤±10%,IR≥1GΩ·μF。

七、选型与替代建议

  1. 同品牌升级:需更高精度(±5%)可选KEMET C1206C105K5R5AUTO(其他参数一致);
  2. 其他品牌替代:Murata GRM188R61C105KA5D(1206封装,X7R,50V,±10%)、TDK C1206X7R1E105K(同参数);
  3. 注意事项:汽车级应用需确认替代型号是否满足AEC-Q200,医疗设备需符合RoHS与REACH标准。

该产品凭借稳定的性能、可靠的认证与广泛的适配性,成为中高压、中等容值MLCC场景的主流选择。

Sourcing availability signal

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
