TCC0402X5R684K160AT 贴片多层陶瓷电容(MLCC)产品概述

TCC0402X5R684K160AT是三环电子(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),专为中低压、常规环境下的电子电路设计,具备容值稳定、可靠性高、贴装效率优等特点,广泛应用于消费电子、小型智能设备等领域。

一、产品基本属性与核心参数

该型号命名规则清晰对应核心参数,便于快速选型:

  • 型号标识解析:TCC(三环品牌代码)+ 0402(封装尺寸)+ X5R(温度系数)+ 684(容值编码:68×10⁴ pF=680 nF)+ K(精度±10%)+ 160(额定电压16V)+ AT(生产工艺/包装代码)。
  • 核心参数汇总: 参数项 数值/规格 产品类型 贴片多层陶瓷电容(MLCC) 标称容值 680 nF(684 pF) 容量精度 ±10%(K级) 额定电压 16 V DC 温度系数 X5R(-55℃~+85℃) 封装尺寸 0402(英制:0.04"×0.02")/1005(公制:1.0mm×0.5mm) 品牌厂商 三环电子(CCTC)

二、关键特性解析

  1. 温度稳定性突出:X5R温度系数下,容量变化率控制在±15%以内(-55℃~+85℃范围),避免因环境温度波动导致电路性能偏移,满足大多数常规应用场景需求。
  2. 小型化高密度设计:0402封装(典型厚度≈0.5mm)大幅节省PCB空间,适配智能穿戴、蓝牙耳机等小型设备的紧凑布局,支持自动化高速贴装。
  3. 无极性与高可靠性:MLCC无极性设计,贴装无需区分正负,降低生产出错率;三环采用成熟多层陶瓷工艺,产品通过125℃/1000h高温寿命测试、湿度循环测试等,可靠性符合行业标准。
  4. 低损耗与批次一致性:陶瓷介质损耗低,适合信号耦合、电源滤波等应用;每批次产品容值、耐压偏差控制在规格范围内,一致性达标率≥99.5%,减少批量生产调试成本。

三、典型应用场景

该型号因参数匹配性强,广泛覆盖以下领域:

  • 消费电子终端:手机、平板、笔记本电脑的DC-DC转换输出滤波、音频耦合电路(耳机接口、扬声器驱动)。
  • 小型智能设备:蓝牙耳机、智能手环、智能手表的蓝牙模块射频耦合、低功耗电源滤波。
  • 工业控制辅助电路:小型PLC、传感器模块的低电压供电去耦、信号干扰抑制。
  • 汽车电子辅助系统:车载USB充电、仪表盘背光控制等16V以下的辅助电路(需确认工作温度≤85℃)。

四、品牌与可靠性保障

三环电子(CCTC)作为国内MLCC主流厂商,该型号具备以下可靠性优势:

  • 环保合规:符合RoHS 2.0、REACH等国际标准,不含铅、镉等有害物质,适配绿色电子产品设计。
  • 严苛测试验证:通过GB/T 2693-2001(电子元器件用陶瓷电容器)、IEC 60384-14等行业标准测试,包括机械振动(10~2000Hz)、**热冲击(-55℃~+125℃循环)**等,确保恶劣环境下的稳定性。
  • 供应链稳定:具备成熟的生产与库存管控体系,支持批量订单快速交付,避免生产断供风险。

五、选型与应用注意事项

  1. 电压余量设计:实际工作电压应低于额定电压的80%(即≤12.8V),避免过压导致电容击穿或容量衰减。
  2. 温度范围匹配:若应用环境温度超过+85℃(如高温工业场景),建议选用X7R(-55℃~+125℃)或更高温度系数的产品。
  3. 精度需求适配:±10%精度满足常规滤波、耦合需求;若对容值精度要求较高(如精密振荡电路),需选用±5%(J级)或±1%(F级)的型号。
  4. 贴装工艺要求:回流焊温度曲线需符合MLCC规范(峰值温度≤245℃,升温速率≤3℃/s),避免热应力导致陶瓷开裂。

六、总结

TCC0402X5R684K160AT作为三环电子的经典中低压MLCC型号,凭借小型化、高可靠性、温度稳定性等特点,成为消费电子、小型智能设备等领域的优选组件。其参数均衡,适配性强,同时符合环保与可靠性标准,能有效降低电路设计与生产的综合成本。

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
