TDK C1005X5R1E474KTK00F 多层陶瓷贴片电容(MLCC)产品概述

一、产品命名与封装解析

TDK C1005X5R1E474KTK00F是一款针对小型化电子设备设计的0402封装多层陶瓷贴片电容(MLCC),其命名严格遵循TDK MLCC的标准规则,各部分含义清晰:

  • C1005:封装代码,对应英制尺寸0402(公制1.0mm×0.5mm×0.5mm,典型厚度),适配高密度贴装场景;
  • X5R:温度特性标识,代表工作温度范围-55℃~+85℃,容值变化范围±15%;
  • 1E:额定电压代码,对应DC 25V(TDK电压体系中,1E=25V);
  • 474:容值代码,换算为47×10⁴ pF=470nF(0.47μF);
  • K:精度等级,±10%;
  • TK00F:系列补充代码,确保贴装兼容性与量产一致性。

二、核心技术参数明细

该产品的参数聚焦小型化、中等容值稳定性,关键指标如下:

参数项 数值/规格 标称容值 470nF(474) 精度 ±10%(K级) 额定电压(DC) 25V 温度特性 X5R(-55℃~+85℃,ΔC/C±15%) 封装尺寸 0402(1005公制) 等效串联电阻(ESR) 典型值≤10mΩ(1kHz下) 环保标准 RoHS 2.0、REACH compliant

补充:MLCC的等效串联电感(ESL)极低,适合高频滤波与信号耦合场景。

三、X5R温度特性的应用优势

X5R是MLCC中容值密度与温度稳定性平衡的典型特性,区别于两类主流特性:

  • NPO(COG):温度稳定性极高(ΔC/C±0.3%),但容值上限低(通常≤100nF),仅适用于射频、高精度振荡电路;
  • Y5V(Z5U):容值密度高(可达μF级),但温度变化大(ΔC/C±22%~-82%),仅适用于对温度不敏感的电源滤波。

C1005X5R1E474KTK00F的X5R特性,使其可在消费电子、IoT设备的常规工作温度范围内保持容值稳定,避免因温度波动导致滤波效果下降或信号失真。

四、典型应用场景

该产品因体积小、容值适中、稳定性好,广泛用于:

  1. 消费电子终端:手机、平板、智能手表的电源滤波(如电池供电回路、CPU供电滤波)、信号耦合(如音频、射频接口);
  2. IoT与可穿戴设备:蓝牙模块、WiFi模块的射频滤波、传感器信号耦合(如加速度传感器、环境传感器的信号通路);
  3. 小型电子模块:电源管理IC(PMIC)的输出滤波、LED驱动电路的噪声抑制;
  4. 工业控制小型单元:小型PLC、传感器节点的电源滤波(需兼顾体积与稳定性)。

五、TDK品质保障与可靠性

TDK作为全球MLCC龙头企业,该产品具备行业领先的可靠性:

  • 工艺一致性:多层陶瓷叠层工艺成熟,量产容值偏差严格控制在±10%以内,适配电子设备量产需求;
  • 抗老化性能:陶瓷材料与电极设计优化,长期工作(1000小时以上)容值变化率≤1%;
  • 环保合规:不含铅、镉等有害物质,符合全球市场准入标准;
  • 贴装兼容性:0402封装适配主流SMT生产线,焊点可靠性高,适合高密度贴装(如手机主板的BGA周边区域)。

注意:该产品为非汽车级MLCC,若需车载应用(如信息娱乐系统),需选择TDK汽车级系列(如C1005X7R,温度范围-55℃~+125℃)。

综上,TDK C1005X5R1E474KTK00F是一款针对小型化电子设备设计的高性价比MLCC,兼顾容值稳定性与体积优势,可满足消费电子、IoT等领域的常规滤波与耦合需求。

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
