TCC0402X5R684K100AT 贴片多层陶瓷电容(MLCC)产品概述

TCC0402X5R684K100AT是三环电子(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),专为低压、高密度电子电路设计,兼顾容量稳定性与体积优势,广泛适配消费电子、IoT终端等领域的小型化需求。

一、产品基本属性

该产品属于贴片式MLCC,采用0402标准封装,核心定位为低压电路的滤波、耦合与去耦元件。MLCC凭借多层陶瓷结构实现高容量密度,相比电解电容体积更小、高频特性更优;三环作为国内老牌电子元器件厂商,产品可靠性与产能稳定性经市场长期验证,是中小批量及量产项目的可靠选型。

二、核心参数详解

2.1 容值与精度

  • 标称容值:680nF(采用“三位数标识法”,“684”表示68×10⁴pF=680nF);
  • 精度等级:±10%(标识“K”),满足绝大多数通用电路的容量误差需求,无需额外校准。

2.2 额定电压与降额建议

  • 额定电压:10V(直流工作电压上限);
  • 降额使用建议:实际工作电压建议不超过8V(额定值的80%),可有效延长产品寿命、降低漏电流,避免因过压导致的性能衰减。

2.3 温度系数(X5R)

  • 温度范围:-55℃ ~ +85℃;
  • 容量变化:在上述温度范围内,容值变化不超过**±15%**;
  • 特性对比:相比Y5V(容量大但温漂可达-82%~+22%),X5R稳定性更优;相比NPO(温漂<±30ppm/℃但容量小),X5R容量范围更广,是“容量-稳定性”的平衡选择。

三、封装与尺寸规格

采用0402英制封装(公制约1.0mm×0.5mm),具体尺寸参数(典型值):

  • 长度:1.0±0.2mm;
  • 宽度:0.5±0.2mm;
  • 厚度:0.5±0.1mm;
  • 焊盘间距:0.4mm(适配常规PCB焊盘设计)。

小体积特性使其可高密度布局在PCB上,适配智能手机、可穿戴设备等对空间要求严苛的产品。

四、典型应用场景

  1. 低压电源滤波:手机、平板的DC-DC转换电路输出滤波,去除电源纹波;
  2. 芯片去耦:MCU、传感器、蓝牙/WiFi模块的电源引脚去耦,抑制高频噪声;
  3. 可穿戴设备:智能手环、手表的低功耗电路(如心率传感器供电滤波);
  4. IoT终端:智能家居传感器(温湿度、人体感应)、无线节点的小型化电路;
  5. 消费电子:TWS耳机、充电宝、小型家电的内部信号耦合/滤波。

五、品牌与可靠性

三环电子(CCTC)是国内MLCC领域的主流厂商,产品通过:

  • 环保认证:RoHS 2.0、REACH(无有害物质);
  • 可靠性测试:高温存储(125℃/1000h)、温度循环(-55℃~+85℃/1000次)、湿度负荷(85℃/85%RH/1000h)等,满足电子设备的长期使用需求;
  • 焊接兼容性:适配回流焊、波峰焊工艺,焊接不良率低,可兼容自动贴装生产线。

六、选型匹配提示

  1. 电压场景:仅适用于10V及以下低压电路,高压场景需选更高额定电压的规格;
  2. 温度要求:若工作环境温度超过85℃(如车载高温区),需选X7R(-55℃~+125℃)或更高温系数的产品;
  3. 精度需求:若电路对容值精度要求±5%以内(如振荡电路),需更换为精度等级“J”(±5%)的规格;
  4. 封装匹配:0402封装需确认PCB焊盘尺寸(建议焊盘长0.6mm、宽0.3mm),避免焊接短路或虚焊。

综上,TCC0402X5R684K100AT凭借小体积、稳定的X5R温度特性与可靠的三环品牌背书,是低压小型化电子电路的高性价比选型。

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
