  4. 封装尺寸:0402英制(公制1005),实际尺寸为长1.0mm±0.1mm、宽0.5mm±0.1mm、厚0.5mm±0.1mm;
  5. 损耗与绝缘:25℃、1kHz下,损耗角正切(tanδ)≤0.15%,绝缘电阻(IR)≥10^10Ω(10V DC测试);
  6. 频率特性:谐振频率约1.5GHz(典型值),适配射频(RF)频段应用。

三、材料与工艺技术特点

依托TDK成熟的陶瓷材料与积层工艺,产品具备以下优势:

  1. Class 1陶瓷配方:采用钛酸钡基低温烧结陶瓷(C0G),无老化效应,容值长期稳定;
  2. 精密积层工艺:超细陶瓷层(厚度≤1μm)与多层内电极堆叠,小体积下实现稳定容值;
  3. 端电极结构:镍(Ni)+锡(Sn)三层设计,兼容无铅回流焊,焊接强度高、耐环境腐蚀;
  4. 内电极材料:钯银合金(Pd-Ag),兼顾高频性能与成本控制。

四、典型应用场景分析

因C0G电容的高精度、低损耗特性,该产品广泛用于以下领域:

  1. 射频通信:WiFi 6/6E、蓝牙5.2、5G基站射频前端(PA、LNA)的滤波、匹配网络;
  2. 精密仪器:示波器、信号发生器、频谱分析仪的计时电路、滤波组件;
  3. 汽车电子:车载信息娱乐系统(IVI)、ADAS传感器的信号调理(部分型号符合AEC-Q200);
  4. 工业控制:PLC、伺服驱动器的高频滤波与信号耦合;
  5. 消费电子:智能手机、平板的射频模块、无线充电电路。

五、可靠性与环境适配性

产品通过多项可靠性测试,适配复杂工作环境:

  1. 温度范围:工作-55℃125℃,存储-40℃85℃;
  2. 耐焊接热:符合J-STD-020,回流焊峰值260℃(10秒)无性能下降;
  3. 机械性能:抗振动(10g~2000Hz,IEC 60068-2-6)、抗冲击(1000g,IEC 60068-2-27);
  4. 环境稳定性:93%RH、40℃下1000小时,容值变化≤±1%,绝缘电阻≥10^9Ω;
  5. 环保合规:符合RoHS 2.0、REACH,无铅无镉。

六、选型与使用注意事项

为确保性能与可靠性,使用需注意:

  1. 电压降额:交流应用按峰值电压降额(如交流10V,峰值14.14V需≤50V);
  2. 焊接工艺:优先回流焊,避免手工焊(高温易致陶瓷开裂),温度曲线需匹配TDK datasheet;
  3. 静电防护:MLCC对静电敏感,需防静电手环、防静电包装,焊接前接地;
  4. 焊盘匹配:0402封装焊盘建议长0.6mm±0.1mm、宽0.3mm±0.1mm,避免桥连;
  5. 存储条件:常温干燥(25℃±5℃,湿度≤60%RH),开封后12个月内使用。

该产品凭借TDK的技术积累与稳定性能,成为高频精密电路的可靠选择,覆盖从消费电子到工业/汽车领域的多样化需求。

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
