TCC0402X7R223K250AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品身份与型号解析

TCC0402X7R223K250AT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),型号各字符精准对应核心属性:

  • TCC:三环电子产品前缀,标识品牌与生产体系;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸),对应公制1005(1.0mm×0.5mm),为小型化电子设备常用封装;
  • X7R:EIA标准温度系数代码,代表工作温度范围**-55℃~+125℃**,容值变化率≤±15%;
  • 223:容值编码,22×10³ pF = 22nF(22000皮法);
  • K:容值精度代码,对应**±10%**;
  • 250:额定直流电压(DC Voltage),即25V;
  • AT:后缀标识包装类型,通常为纸带编带(Tape & Reel),适配自动化贴装。

二、核心技术参数明细

该产品参数贴合通用电子电路设计需求,关键指标如下:

参数项 规格值 备注 封装类型 0402(英制)/1005(公制) 贴片式,无引脚设计 容值 22nF(223) 容值编码:前两位有效数字+第三位10的幂次 容值精度 ±10%(K) 满足大多数通用电路精度要求 额定直流电压 25V 建议降额至80%(≤20V)使用更安全 温度系数 X7R 宽温区稳定性优异 工作温度范围 -55℃~+125℃ X7R材质标准范围 损耗角正切(tanδ) ≤0.015(1kHz,25℃) 低损耗,适合信号耦合与滤波 介电常数(εr) ~3000(典型值) 平衡容值密度与稳定性 尺寸(长×宽×高) 1.0mm×0.5mm×0.5mm(典型) 0402封装公制尺寸

三、材质与结构特点

TCC0402X7R223K250AT采用多层陶瓷叠层结构,核心优势源于材质与工艺:

  1. 陶瓷介质:采用X7R型钛酸钡基陶瓷,兼具高介电常数与宽温稳定性——既避免Y5V材质(温度波动大)的容值漂移,又比NPO材质(介电常数低)更易实现小体积大容量;
  2. 叠层电极:内部电极采用镍(Ni)或银钯(Ag-Pd)合金,通过流延、叠层、烧结工艺成型,电极与陶瓷层交替叠加,提升容值密度;
  3. 表面处理:外部电极镀镍/镀锡(Ni/Sn),适配回流焊、波峰焊等贴装工艺,焊接可靠性高;
  4. 环保合规:符合RoHS、REACH标准,不含铅、镉等有害物质,适配绿色电子产品设计。

四、典型应用场景

该产品因小体积、宽温稳定、中低压适配,广泛覆盖以下领域:

  1. 消费电子:手机、平板、蓝牙耳机的电源滤波(VCC纹波抑制)、音频信号耦合、射频前端匹配;
  2. 汽车电子:车载仪表、中控屏的辅助电源电路(适配-40℃~+85℃车载环境)、传感器信号调理(胎压/温度传感器滤波);
  3. 工业控制:PLC输入输出电路滤波、电机驱动EMI抑制、工业传感器信号去耦;
  4. 通信设备:路由器电源模块滤波、以太网接口信号滤波、小型基站射频滤波;
  5. 智能家居:智能音箱电源滤波、Wi-Fi模块信号匹配。

五、性能优势与市场定位

(1)核心优势

  • 温度稳定性:X7R材质在-55℃+125℃内,容值变化≤±15%,远优于Y5V(±20%-80%);
  • 小型化适配:0402封装体积仅0.5mm³,节省PCB空间,满足便携式设备高密度设计;
  • 性价比突出:比NPO材质成本低30%+,同时容值稳定性优于Y5V,是通用电路最优选择;
  • 高可靠性:经过温度循环、湿度试验、焊接应力测试,失效率低于行业平均;
  • 贴装兼容:纸带编带包装适配自动化贴片机,适合大规模生产。

(2)市场定位

定位通用型中低压MLCC,替代同类X7R材质0402封装产品,目标客户为消费电子、汽车电子、工业控制领域的OEM/ODM厂商及电子工程师。

六、包装与存储要求

  1. 包装:纸带编带(Tape & Reel),每盘2000个(或5000个,依批次),编带宽度8mm,适配标准贴片机;
  2. 存储:温度25±5℃,相对湿度≤60%,避免阳光直射与潮湿;存储时间≤12个月,超期需复检;
  3. 焊接注意:
    • 回流焊:峰值温度260±5℃,恒温区时间≤10秒;
    • 波峰焊:温度245±5℃,焊接时间≤3秒;
    • 避免多次焊接,防止陶瓷开裂。

该产品以稳定性能与高性价比,成为通用电子电路的主流选择,可满足多数中低压场景的设计需求。

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
