TCC0402X5R475M100AT贴片电容产品概述

TCC0402X5R475M100AT是三环电子(CCTC) 推出的一款小体积、高可靠性多层陶瓷贴片电容(MLCC),专为低电压、高密度电路设计,核心参数满足消费电子、物联网等领域的常规滤波、耦合需求。以下从产品信息、参数、特性、应用等维度展开概述。

一、产品基本信息

该产品属于三环电子“TCC”系列MLCC,型号各部分含义清晰:

  • TCC:三环电子(CCTC)品牌代码,三环作为国内老牌MLCC厂商,产品覆盖全封装系列;
  • 0402:英制封装尺寸(对应公制1005,即长度1.0mm±0.1mm、宽度0.5mm±0.1mm);
  • X5R:陶瓷材质类型,平衡容值密度与温度稳定性;
  • 475M:容值标识(47×10⁵pF=4.7μF),“M”代表精度±20%;
  • 100:额定直流电压10V;
  • AT:封装细节或批次标识(无特殊电气含义)。

二、关键电气参数解析

2.1 容值与精度

容值为4.7μF(475代码),精度±20%(M级),属于MLCC通用精度等级。该容值适合大多数电源滤波场景(如10μF以下去耦电容搭配),精度满足一般电路耦合、旁路需求,无需高精度场合的额外成本。

2.2 额定电压

额定直流电压为10V,适用于3.3V、5V等低电压系统(留有20%以上安全裕量)。需注意:实际工作电压需低于10V,避免过压导致陶瓷介质不可逆击穿。

2.3 温度特性

X5R材质温度范围为**-55℃~+85℃**,容值变化率≤±15%。相比Y5V材质(容值变化±20%以上)稳定性更高,相比NP0(C0G)材质(容值变化≤±0.05%)虽稳定性略低,但能在小体积下实现更大容值,是“性能与体积平衡”的典型选择。

三、封装与物理特性

3.1 封装尺寸

采用0402英制封装(公制1005),是小型电子设备最常用封装之一。尺寸(长×宽)1.0mm×0.5mm,厚度0.5mm(典型值),适配绝大多数小型贴片机(如YAMAHA、JUKI小间距贴装头),支持高密度PCB设计(如智能手机主板多层板)。

3.2 物理结构

多层陶瓷电容结构,数十层陶瓷介质与金属电极交替叠层,两端引出镍-锡镀层电极(无引脚),表面平整无凸起,适合回流焊工艺(焊接温度峰值260℃左右,符合MLCC焊接要求)。

四、可靠性与环保特性

  1. 环保认证:通过RoHS 2.0认证,无铅、无镉、无汞,符合欧盟环保要求,可用于出口设备;
  2. 焊接可靠性:电极镀层附着力强,回流焊后无虚焊、假焊风险(三环通过IPC-A-610E标准检测);
  3. 长期稳定性:高纯度钛酸钡基陶瓷介质,耐老化性能良好,额定条件下使用寿命超10万小时。

五、典型应用场景

TCC0402X5R475M100AT的小体积、低电压特性,使其成为以下场景理想选择:

  1. 消费电子:智能手机PMIC去耦、音频接口耦合,平板电脑WiFi模块滤波;
  2. 物联网设备:低功耗MCU(如STM32L0)电源滤波、温湿度传感器接口旁路;
  3. 小型家电:智能遥控器按键电路滤波、蓝牙音箱音频耦合;
  4. 汽车电子(低功耗):车载USB充电口EMI滤波(需确认环境温度≤85℃)。

六、选型与使用注意事项

  1. 电压裕量:实际工作电压≤8V(留20%裕量),避免过压;
  2. 温度限制:若环境温度超85℃(如高温工业场景),需更换X7R材质(-55℃~+125℃);
  3. 贴装工艺:PCB焊盘建议0.6mm×0.3mm,回流焊温度曲线需符合MLCC要求(预热150℃~180℃,峰值260℃±5℃,时间≤10s);
  4. 存储条件:未开封产品存于-40℃~+60℃、湿度≤60%环境,开封后12个月内使用完毕,避免电极氧化。

总结:TCC0402X5R475M100AT是性价比突出的小体积MLCC,适合低电压、常规温度环境下的滤波、耦合需求,三环电子的品牌保障使其可靠性具备竞争力,是消费电子、物联网等领域的常用选型。

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
