TCC0402X7R474K100AT 贴片陶瓷电容(MLCC)产品概述

TCC0402X7R474K100AT是国内知名电子元器件品牌三环(CCTC) 推出的通用型多层陶瓷电容(MLCC),专为低压、小型化电子设备设计,兼具高可靠性与成本效益,广泛应用于消费电子、物联网、小型家电等领域。

一、产品基本信息

该型号MLCC采用0402英制贴片封装(对应公制尺寸约1.0mm×0.5mm),介质类型为X7R,核心参数明确:容值470nF(标识“474”,即47×10⁴pF)、精度±10%(标识“K”)、额定电压10V。产品符合RoHS无铅环保标准,可直接用于主流电子设备批量生产。

二、核心性能参数详解

1. 容值与精度

容值稳定在470nF,±10%的精度范围(K档)满足绝大多数通用电路需求,无需额外高精度匹配,降低设计复杂度。批量产品参数离散度≤5%,一致性优于行业平均水平。

2. 温度特性

采用X7R陶瓷介质,温度系数定义为:-55℃~+125℃范围内,容值变化不超过±15%,可适应宽温环境(如车载辅助电路、户外小型设备),避免极端温度下性能波动。

3. 额定电压

额定电压10V,适用于低压直流电路(3.3V、5V供电系统),电压降额后可长期稳定工作,无击穿风险。

三、封装与工艺特点

1. 小型化封装

0402封装尺寸紧凑,可显著缩小PCB面积,适配智能手机、智能手环、无线耳机等便携式设备的高密度布局需求,有效降低整机体积。

2. 叠层工艺优势

三环采用成熟的多层陶瓷叠层工艺,电极与介质层均匀分布,确保:

  • 低损耗:高频下(1kHz~1MHz)损耗角正切值≤0.02,保持稳定滤波性能;
  • 机械强度高:可承受回流焊、振动(10-2000Hz/1.5g)等环境应力,无开裂风险;
  • 一致性好:批量产品参数离散度控制在5%以内,适合自动化贴装。

3. 环保无铅

产品电极采用无铅锡膏,符合欧盟RoHS、中国GB/T 26572等环保标准,无有害物质残留,可出口全球市场。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑的电源滤波、信号耦合;无线耳机的充电电路、蓝牙模块匹配。
  2. 物联网模块:低功耗传感器节点、WiFi模块的直流电源去耦,提升信号稳定性。
  3. 小型家电:智能插座、加湿器的控制电路,替代传统电解电容实现小型化。
  4. 汽车电子(低压辅助):车载USB充电口、仪表盘背光电路的滤波,适应车载-40℃~+85℃环境。

五、可靠性与质量保障

三环作为国内MLCC龙头企业,该型号通过多项权威认证:

  • 质量体系:ISO9001、IATF16949(汽车级认证);
  • 可靠性测试:额定电压漏电流测试(≤1μA)、回流焊耐温测试(240℃/10s无失效)、湿热测试(85℃/85%RH/1000h);
  • 使用寿命:在额定条件下(25℃、5V工作电压),平均无故障时间(MTBF)≥10⁶小时,满足长期稳定运行需求。

六、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即≤8V),避免过压导致介质击穿。
  2. 温度限制:工作环境温度不得超过125℃,极端低温(<-55℃)下需验证容值稳定性。
  3. 焊接工艺:回流焊温度曲线需符合MLCC标准(峰值230-240℃,升温速率≤3℃/s),禁止手工焊接时过热。
  4. 静电防护:MLCC对静电敏感,生产/组装过程需佩戴静电手环,使用防静电包装与工作台。
  5. 容值匹配:若需高精度电路(如时钟振荡),建议搭配NPO介质电容,本型号仅适用于通用滤波、耦合场景。

该产品凭借小型化、高可靠性与成本优势,成为低压通用电路的主流选型之一,可满足多数中低端电子设备的性能需求。

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
