  • 损耗因数(DF):典型值≤0.15%(高频下能量损耗低,适配射频电路);
  • 工作温度范围:-55℃至125℃(覆盖工业级环境温度需求)。

2.2 物理与工艺特性

  • 封装形式:0402贴片式(表面贴装,兼容回流焊、波峰焊工艺);
  • 尺寸规格:长1.0mm×宽0.5mm×厚0.5mm(典型值,公差±0.1mm);
  • 端电极:无铅锡膏(Sn-Cu-Ni),符合RoHS 2.0、REACH环保指令;
  • 介质材料:C0G陶瓷(钛酸钡基稳定型介质,无直流偏置效应)。

三、典型应用场景

该产品凭借温度稳定性、小体积、低损耗三大优势,广泛应用于:

  1. 高频射频电路:智能手机、基站、路由器中的RF滤波器、振荡电路、匹配网络(低损耗减少信号衰减);
  2. 精密模拟电路:运算放大器反馈电容、信号滤波电容(容值不受温度/电压波动影响,保证电路精度);
  3. 可穿戴与IoT终端:智能手表、传感器节点(0402封装提升PCB密度);
  4. 工业控制电路:PLC、伺服驱动器中的精密定时电路(宽温范围适应工业环境);
  5. 医疗电子设备:便携式监护仪信号调理电路(高可靠性满足医疗级需求)。

四、产品优势与差异化

相比同规格竞品,TDK该型号具有突出优势:

  • 极致温度稳定性:C0G介质几乎无温度漂移,避免电路性能随环境波动;
  • 无直流偏置效应:电容值不受工作电压影响(区别于X7R/X5R的容值下降问题);
  • 高可靠性与一致性:TDK成熟工艺保证批量产品容值、损耗一致性,符合AEC-Q200(可选)标准;
  • 小体积高密度:0402封装可实现每平方厘米PCB集成超100个电容,满足小型化需求;
  • 宽电压覆盖:100V额定电压兼容低压与中压电路(无需过度降额)。

五、应用与选型注意事项

为确保性能稳定,需注意:

  1. 电压降额:直流工作电压≤100V,交流应用峰值电压≤70%额定电压;
  2. 焊接工艺:回流焊峰值温度230-245℃,时间≤10s(避免热应力损坏);
  3. 频率适配:1GHz以下频率性能优异,高频应用需注意寄生电感(≤0.5nH);

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
