TCC0042X5R474K250AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与核心类别

TCC0402X5R474K250AT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),属于中温稳定型电容范畴,主打小型化、高可靠性,主要面向消费电子、小型工业设备、通信终端等领域的基础滤波、耦合、去耦等电路设计,是当前高密度SMT贴装设备中常用的被动元件之一。

二、关键性能参数详细说明

该产品核心参数均符合行业通用标准,具体解读如下:

  1. 容值与精度:标称容值470nF(即0.47μF),采用三位数字标识法(474)——前两位为有效数字(47),第三位为10的幂次(4→10⁴),计算得47×10⁴pF=470000pF=470nF;精度等级为±10%(标识“K”),适用于对容值精度要求不苛刻的滤波、耦合场景(如电源噪声抑制)。
  2. 额定电压:25V(直流),实际使用需确保工作电压不超过额定值(建议留10%-20%安全裕量,避免过压击穿);若为交流电压,需按有效值计算,且需结合频率特性评估。
  3. 温度系数:X5R,对应的温度范围为**-55℃至+85℃**,在此区间内容值变化控制在±15%以内,稳定性优于Y5V等低阶电容,能满足多数常规环境(如室内电子设备、普通工业场景)的温度需求。
  4. 封装规格:0402(英制代码,对应公制尺寸1.0mm×0.5mm),属于超小型贴片封装,适配高密度电路板设计(如智能手机主板、小型传感器模块)。

三、封装尺寸与物理特性

0402封装的物理参数(典型值)如下:

  • 长度:1.0±0.1mm
  • 宽度:0.5±0.1mm
  • 厚度:0.5±0.1mm
  • 电极结构:两端银浆电极(表面镀锡/镍),适配回流焊、波峰焊工艺
  • 外观:灰色陶瓷基体+银白色电极,符合SMT视觉检测(AOI)的识别要求
  • 重量:约0.005g(超轻量,不影响小型设备整体重量)

四、典型应用场景梳理

该产品因体积小、容值稳定,广泛应用于以下场景:

  1. 消费电子终端:手机、平板、智能手表的电源滤波(DC-DC转换模块输出端)、音频信号耦合、按键电路去耦(抑制按键抖动干扰);
  2. 小型家电与智能家居:遥控器、智能插座、加湿器的控制电路滤波(避免电磁干扰导致误触发);
  3. 通信设备:小型路由器、WiFi模块、蓝牙模块的射频辅助滤波(2.4GHz/5GHz频段噪声抑制);
  4. 工业控制小型模块:微型PLC、传感器节点的电源去耦(稳定模拟信号传输);
  5. 汽车电子(低功耗部分):车载蓝牙、USB充电口的滤波电路(需确认环境温度是否在X5R范围内,避免高温下容值漂移)。

五、品牌可靠性与合规性

三环电子(CCTC)是国内MLCC领域的主流厂商,该产品具备以下可靠性保障:

  1. 质量体系认证:通过ISO9001质量管理体系、IATF16949汽车电子质量管理体系(基础可靠性符合汽车级要求,本款为消费级但具备稳定表现);
  2. 合规性认证:符合RoHS 2.0(无铅、无镉等10类有害物质)、REACH法规要求,满足欧盟、北美市场准入;
  3. 可靠性测试:经过高温老化(125℃×1000h)、湿度循环(-40℃85℃/85%RH)、机械振动(10Hz2000Hz)等测试,批量生产一致性达99.5%以上;
  4. 供货稳定性:三环具备年产能超500亿只的MLCC生产线,能满足中小批量及大批量订单需求,交货周期稳定(常规订单7-15天)。

六、选型使用注意事项

  1. 电压匹配:避免在超过25V直流电压下使用,若为高压场景(如30V以上)需换用额定电压更高的型号(如35V、50V);
  2. 温度场景:不建议在环境温度持续超过+85℃的场景使用(如高温工业炉、汽车发动机舱),否则容值变化会超出±15%的设计范围;
  3. 精度需求:若电路需高精度容值(如振荡电路、精密信号滤波),需选择±5%(J)或±1%(F)精度的电容,本款仅适用于普通滤波;
  4. 大电流场景:0402封装的MLCC电流承载能力有限(典型值<1A),大电流滤波(如电源主滤波)建议选用更大封装(如0603、0805)或电解电容;
  5. 焊接工艺:回流焊温度需控制在230℃~260℃区间(峰值温度不超过260℃),避免高温损坏陶瓷基体导致容值下降。

该产品凭借小型化、高稳定性及成本优势,成为当前消费电子与小型工业设备中基础滤波电路的主流选型之一。

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.
