TCC0805X7R225K250FT 贴片陶瓷电容(MLCC)产品概述

一、产品基本属性与核心参数

TCC0805X7R225K250FT是一款多层陶瓷贴片电容(MLCC),由国内MLCC龙头厂商CCTC(三环集团)生产,核心参数明确且适配多数电子电路需求:

  • 封装:0805(英制,对应公制2012,尺寸约2.0mm×1.2mm×1.0mm,标准贴片封装);
  • 容值:2.2μF(标注“225”,即22×10⁵ pF=2.2μF);
  • 精度:±10%(标注“K”,工业级常用精度等级,兼顾成本与稳定性);
  • 额定电压:25V DC(标注“250”,需注意为直流额定电压,交流应用需按降额规则调整至≤12.5V);
  • 材质:X7R(钛酸钡基陶瓷,EIA标准温度系数分类);
  • 环保认证:符合RoHS 2.0、REACH标准,无铅无卤,适配全球市场要求。

二、温度特性与稳定性(X7R材质核心优势)

X7R是MLCC中中等容值+稳定温度特性的主流材质,其性能指标直接决定了产品的环境适应性:

  • 工作温度范围:-55℃至+125℃(覆盖工业、消费电子常见环境温度,如高温车间、户外设备);
  • 容值变化率:≤±15%(部分批次可达±10%),远优于Y5V材质(容值变化可达-80%~+20%),但略逊于NPO(±0.05%);
  • 电压偏置特性:25V DC下容值下降≤10%,避免电源电压波动导致容值漂移,适合滤波、耦合等对容值稳定性要求较高的场景。

对比其他材质,X7R平衡了容值、温度稳定性与成本,是大多数电子电路的首选材质之一。

三、封装设计与焊接兼容性

0805封装是MLCC中尺寸与性能平衡的经典封装,适配性强:

  • 尺寸优势:比0402封装(1.0mm×0.5mm)容值承载能力更强,比1206封装(3.0mm×1.6mm)占用PCB面积更小,适合高密度布线与常规设计;
  • 焊接兼容性:支持回流焊(推荐温度曲线:预热150-180℃,峰值230-250℃)、波峰焊(需注意元件方向,避免锡桥),焊接良率≥99.5%;
  • 机械强度:封装结构紧凑,抗振动(10-2000Hz,加速度2g)、抗冲击(峰值加速度100g)性能满足IEC 60068-2标准,适合移动设备与工业场景。

四、电气性能关键指标解析

除基础参数外,以下电气指标决定了产品的实际应用表现:

  1. 直流漏电流(DCL):25℃、25V DC下,漏电流≤0.01CV(即0.01×25V×2.2μF=0.55μA),低漏电流适合电池供电设备(如智能手环);
  2. 损耗角正切(tanδ):1kHz、1Vrms下≤5%,损耗小,避免高频应用中过度发热,适合射频辅助耦合、电源滤波;
  3. 耐电压特性:额定电压25V DC,过压测试(1.5倍额定电压,37.5V保持5秒)无击穿,可靠性满足工业级要求;
  4. 老化特性:X7R材质老化速率慢,≤0.5%/decade(十年),长期使用容值变化可忽略,适合长寿命产品(如智能家居设备)。

五、品牌可靠性与供货保障

CCTC(三环集团)作为国内MLCC行业龙头,产品可靠性有全流程保障:

  • 认证齐全:通过ISO 9001、ISO/TS 16949(汽车级)、IEC 60384-14(电子元器件安全标准);
  • 可靠性测试:完成温度循环(-55℃~+125℃,1000次)、湿度测试(85℃/85%RH,1000小时)、高温存储(125℃,1000小时)等全流程测试;
  • 供货稳定:年产能超千亿只,产品一致性(容值偏差≤±10%)好,适合批量生产需求,避免断供风险。

六、典型应用领域

该产品因参数平衡,应用覆盖多领域:

  1. 消费电子:智能手机/平板的电源滤波(Vcore滤波、Type-C接口滤波)、音频信号耦合;
  2. 工业控制:PLC、变频器的电源模块滤波、控制电路耦合;
  3. 通信设备:路由器、交换机的电源滤波、EMI滤波(配合电感组成LC滤波);
  4. 汽车电子(辅助级):车载音响、仪表盘的信号处理电路(非安全关键场景);
  5. 电源产品:开关电源的输出滤波、LED驱动电源的稳压滤波。

总结

TCC0805X7R225K250FT是一款高性价比、性能稳定的MLCC,兼顾了容值、精度、温度稳定性与封装尺寸,适用于大多数中低端至中端电子电路设计。CCTC的品牌保障与可靠的电气性能,使其成为工程师优化电路设计的优选元件。

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
