TCC0402X7R683K250AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心参数梳理

TCC0402X7R683K250AT是三环电子(CCTC)推出的一款小型化贴片MLCC,核心参数明确适配中低电压、中等容值的电路需求:

  • 型号全称:TCC0402X7R683K250AT
  • 封装规格:0402(英制,0.04英寸×0.02英寸)/1005(公制,1.0mm×0.5mm)
  • 标称容值:68nF(容值代码“683”,即68×10³pF)
  • 精度等级:±10%(代码“K”,满足一般电路的容值误差要求)
  • 额定电压:25V(型号中“250”对应25V额定值,适合低压电路)
  • 介质材料:X7R型陶瓷
  • 温度特性:-55℃~+125℃范围内,容值变化≤±15%

二、介质材料与技术特性

该电容采用X7R型多层陶瓷介质,是MLCC领域的主流选择,核心技术优势如下:

  1. 温度稳定性:在宽温度区间(-55℃至+125℃)内,容值波动控制在±15%以内,可适应户外、工业等不同环境温度场景;
  2. 容值密度平衡:相比NP0等低容值介质,X7R能实现68nF的中等容值,同时避免高容值介质(如Y5V)的温度漂移问题;
  3. 高频性能优异:MLCC本身无极性、寄生电感/电阻低,X7R介质进一步优化了高频阻抗特性,适合信号耦合、滤波等高频应用;
  4. 无极性设计:无需区分正负极,安装便捷,可降低SMT生产中的出错概率。

三、封装尺寸与生产适配性

0402封装是电子设备小型化的核心封装之一,尺寸仅1.0mm(长)×0.5mm(宽)×0.5mm(厚,批次略有差异),适配性突出:

  • 高密度布局:可在有限PCB空间内集成更多元件,满足智能手机、可穿戴设备的小型化需求;
  • 自动化兼容:符合SMT标准,支持高速贴片机批量生产,提升生产效率;
  • 焊接可靠性:支持回流焊、波峰焊等常规工艺,焊接后无虚焊、脱落问题,符合行业焊接标准。

四、典型应用场景

结合参数特性,该电容主要用于以下场景:

  1. 消费电子终端:智能手机、平板电脑的电源滤波(DC-DC模块输出)、音频/射频信号耦合;
  2. 可穿戴设备:智能手环、TWS耳机的传感器信号滤波、电池管理辅助滤波;
  3. 物联网节点:智能家居传感器、低功耗IoT模块的信号降噪、电源稳定;
  4. 小型电子模块:蓝牙/WiFi模块的内部滤波,提升信号传输质量;
  5. 工业小型设备:小型PLC、传感器模块的辅助电路,适应环境温度变化。

五、可靠性与环保要求

三环电子对该产品品控严格,符合多项行业标准:

  • 环境适应性:工作温度-55℃+125℃,存储温度-40℃+85℃,湿度0~95%RH(无凝露);
  • 可靠性测试:通过125℃/2000小时额定电压寿命测试(容值变化≤±10%)、温度循环测试,确保长期稳定;
  • 环保合规:符合RoHS 2.0、REACH指令,采用无铅封装,满足全球市场环保要求。

六、品牌与品质保障

三环电子(CCTC)是国内MLCC领域的成熟厂商,该产品具备:

  • 一致性好:批量产品容值、精度、电压特性一致,减少电路参数波动;
  • 供货稳定:规模化生产能力,可满足客户批量采购需求;
  • 技术支持:提供完整 datasheet 及售后技术服务,帮助客户解决应用问题。

该产品凭借紧凑封装、稳定特性及高性价比,成为小型化电子设备的常用基础元件之一。

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
