TCC0805X7R475K250FT 贴片陶瓷电容(MLCC)产品概述

一、产品核心身份与型号编码解析

TCC0805X7R475K250FT是三环电子(CCTC) 推出的工业级多层片式陶瓷电容(MLCC),型号编码清晰对应核心技术参数:

  • TCC:三环电子品牌代码;
  • 0805:英制封装尺寸(对应公制2.016mm×1.27mm,厚度约0.8mm,符合IPC-J-STD-001标准);
  • X7R:温度系数代码(下限-55℃,上限+125℃,容值变化≤±15%);
  • 475:容值代码(47×10⁵ pF=4.7μF);
  • K:容值精度(±10%);
  • 250:额定直流电压(25V DC);
  • FT:三环常规工业级系列标识。

二、关键技术参数与性能指标

该产品核心参数满足中低功耗电路的通用需求,具体如下:

指标项 规格参数 备注 标称容值 4.7μF 容值代码475 容值精度 ±10%(K级) 工业级通用精度 额定电压 25V DC 无极性,直流应用场景 工作温度范围 -55℃ ~ +125℃ X7R介质特性 容值温度变化率 ≤±15%(25℃基准) 符合EIA标准 损耗角正切(DF) ≤2%(1kHz, 25℃) 铁电陶瓷介质典型值 绝缘电阻(IR) ≥10⁴ MΩ(25℃, 10V DC) 高温下保持稳定绝缘性能 环保认证 RoHS 2.0、REACH SVHC 无铅无卤,符合欧盟环保要求

三、材料特性与性能优势

TCC0805X7R475K250FT采用X7R铁电陶瓷介质,结合MLCC多层叠层结构,具备以下核心优势:

  1. 容值密度高:X7R介质介电常数(εᵣ≈2000-3000)远高于NPO介质,可在0805小封装内实现4.7μF容值,满足小型化电路需求;
  2. 温度稳定性优异:相比Y5V等介质(容值变化≤±20%~+82%),X7R的容值漂移控制在±15%以内,适合宽温环境(如工业控制、车载辅助电路);
  3. 高频特性良好:多层叠层结构无引线寄生电感,谐振频率可达100MHz以上,适合中高频滤波、耦合电路;
  4. 可靠性与一致性:三环电子采用成熟的叠层工艺,产品批次一致性好,经高温存储(125℃×1000h)、温度循环(-55~125℃×1000次)测试,失效率符合工业级标准。

四、典型应用场景

该产品适用于低中压、宽温范围的通用电路,核心应用场景包括:

  1. 消费电子:智能手机、平板、智能穿戴的电源滤波(Vcc去耦)、信号耦合(音频/射频链路);
  2. 工业控制:PLC模块、传感器接口、电机驱动电路的抗干扰滤波;
  3. 通信设备:路由器、交换机、基站的电源稳压滤波;
  4. 家电产品:电视、空调、洗衣机的控制板电源电路;
  5. 车载辅助电子:车载音响、仪表盘、倒车雷达的低中压电路(需确认具体车规要求,部分批次支持AEC-Q200)。

五、选型与使用注意事项

为确保产品性能与可靠性,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即20V DC),延长使用寿命(降额系数可参考IPC标准);
  2. 焊接工艺:仅适用于回流焊(温度曲线:预热150-180℃×60-120s,峰值230-245℃×30-60s),禁止手工焊接(易损坏介质层);
  3. 存储条件:未开封产品需存储在常温干燥环境(25±5℃,湿度40-60%RH),存储期不超过12个月;
  4. PCB焊盘设计:焊盘尺寸建议0.6mm×1.0mm(间距0.2mm),符合IPC-7351标准,避免焊盘过大导致焊接应力集中;
  5. 温度限制:禁止在超过125℃的环境中长时间工作,否则会导致容值不可逆漂移。

六、品牌与市场定位

三环电子(CCTC)是国内MLCC领域的主流供应商,产品覆盖工业级、汽车级(AEC-Q200认证)全系列,TCC0805X7R475K250FT作为其通用型产品,具备性价比高、供货稳定的特点,广泛应用于国内电子制造企业的中低端产品,同时满足出口欧盟的环保要求。

该产品平衡了容值密度、温度稳定性与成本,是替代进口通用MLCC的优质选择,适用于对精度、宽温有基本要求的批量应用场景。

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
