TCC0805X7R105K250FT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性与型号解析

TCC0805X7R105K250FT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),覆盖工业级与消费电子级应用场景。其型号拆解可清晰对应核心参数:

  • TCC:三环电子的品牌代码标识;
  • 0805:封装尺寸(英制代码),对应公制规格为2.0mm×1.25mm(长×宽),常规厚度约0.8mm;
  • X7R:温度系数,代表工作温度范围**-55℃~125℃**,容量变化率控制在±15%以内;
  • 105K:容量与精度,“105”=10×10⁵ pF=1uF(1000nF),“K”为精度等级(±10%);
  • 250:额定直流电压,实际为25V(型号简化标注);
  • FT:三环内部工艺后缀,通常对应无铅环保封装、卷带包装(适配自动化贴装)。

二、核心性能参数详解

该产品针对通用低压电路设计,兼顾性能与成本平衡:

  1. 容量与精度:标称1uF,±10%精度满足90%以上滤波、耦合需求,无需额外高精度匹配;
  2. 电压与耐压:额定直流25V,短时间瞬态耐压≤30V(参考三环 datasheet),建议电路工作电压留20%余量(≤20V);
  3. 温度特性:X7R宽温范围覆盖车载、工业车间、户外设备等场景,-55℃~125℃内容量变化≤±15%,避免极端温度下性能波动;
  4. 损耗与频率:1kHz~1MHz频率范围内容量稳定(偏差≤5%),高频损耗(DF值)约0.5%(1kHz下),远低于电解电容,适合滤除开关电源纹波。

三、适用场景与应用优势

因体积紧凑、性能均衡,该产品广泛应用于:

  1. 消费电子:手机主板CPU供电滤波、平板音频耦合,0805封装适配高密度PCB;
  2. 工业控制:PLC传感器模块去耦、变频器电源滤波,宽温特性应对-20℃~85℃车间环境;
  3. 汽车电子(低压):中控屏信号滤波(部分批次符合AEC-Q200车规);
  4. 通信设备:路由器电源滤波,抗电磁干扰(EMI)性能良好。

核心优势:

  • 性价比高:通用型MLCC,成本低于高精度/高容值系列;
  • 可靠性强:三环成熟叠层工艺,无铅电极(RoHS/REACH合规),焊接合格率≥99.5%;
  • 体积紧凑:比1206封装小30%,适合小型化设计。

四、封装与可靠性设计

  1. 封装工艺:表面贴装(SMD),银钯合金(Ag-Pd)电极降低热应力,陶瓷外壳耐机械冲击(跌落测试符合IEC 60068-2-32);
  2. 可靠性指标:
    • 寿命:125℃/25V下≥10⁶小时;
    • 温度循环:-55℃~125℃循环1000次,容量变化≤±10%;
    • 湿度稳定:85℃/85%RH下1000小时,容量变化≤±10%;
  3. 包装方式:8mm/12mm卷带,每卷10000~50000个,适配自动化贴装。

五、选型匹配注意事项

  1. 电压匹配:严禁超25V额定值,瞬态尖峰需并联TVS管;
  2. 温度适配:长期超125℃需换X8R(-55℃~150℃),但成本提升;
  3. 偏置降额:25V偏置下容量降额10%(变为900nF),选型需考虑实际偏置;
  4. 精度需求:需±5%精度则换“J”档(如105J),容量不变但成本略增。

该产品作为三环主流通用MLCC,是低压电子设备基础电路的常规选型,平衡了性能、成本与可靠性,覆盖多场景应用需求。

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
