TCC1206X7R472K102FT 贴片电容产品概述

TCC1206X7R472K102FT是三环电子(CCTC) 推出的中高压表面贴装多层陶瓷电容(MLCC),专为温度波动大、需稳定容值的电路设计,具备宽温适应性、高可靠性等特点,广泛应用于工业控制、电源、通信等领域。

一、产品基本信息

该型号为三环常规系列MLCC,核心标识对应参数明确:

  • 型号编码:TCC(品牌前缀)+1206(封装)+X7R(介质)+472(容值:47×10²pF=4.7nF)+K(精度±10%)+102(额定电压:10×10²V=1kV)+FT(工艺后缀);
  • 产品类型:表面贴装多层陶瓷电容(MLCC);
  • 品牌:三环电子(CCTC),国内MLCC龙头企业,专注陶瓷电容研发超20年。

二、核心技术参数

参数项 规格参数 备注 标称容值 4.7nF(472pF) 10%误差范围内 容值精度 ±10%(K级) 符合EIA国际标准 额定直流电压 1kV(1000V) 交流电压需降额使用 介质材料 X7R 宽温稳定型介质 封装规格 1206(英制) 公制3.2mm×1.6mm 工作温度范围 -55℃ ~ +125℃ 工业级宽温适应性 绝缘电阻 ≥10⁹Ω(25℃,10V DC) 典型值随温度升高略有下降 损耗角正切(tanδ) ≤0.025(1kHz,25℃) 低损耗适合滤波应用

三、X7R介质材料特性

X7R是MLCC核心温度稳定型介质,核心特点:

  1. 温度范围明确:覆盖-55℃至+125℃,满足工业、车载等宽温场景;
  2. 容值稳定:全温区容值变化≤±15%,远优于Y5V/Y5P等低稳定介质;
  3. 容值与封装平衡:介电常数(εr)2000~4000,可实现nF级容值与小封装(1206)的兼容;
  4. 应用适配:适合滤波、耦合、旁路等通用电路,不适合高精度振荡(需NPO)或超大容值(需Y5V)场景。

四、封装与焊接兼容性

  1. 封装尺寸:1206英制封装,公制尺寸为长度3.2mm±0.2mm,宽度1.6mm±0.2mm,厚度1.0mm±0.1mm(典型值,以官方 datasheet 为准);
  2. 焊接工艺:支持标准表面贴装工艺:
    • 回流焊:符合IPC-J-STD-020,最高回流温度260℃(10秒内);
    • 波峰焊:最高温度240℃(3秒内);
  3. 电极镀层:镍/锡(Ni/Sn)无铅镀层,焊接兼容性好,环保达标。

五、典型应用场景

因1kV额定电压与X7R宽温特性,主要应用于中高压、宽温环境:

  1. 开关电源/LED驱动:次级滤波、高压耦合(如高压LED串电源滤波);
  2. 工业控制:PLC、变频器的信号耦合、抗干扰滤波;
  3. 通信基站:射频前端辅助滤波、电源模块滤波;
  4. 医疗设备:低噪声电源滤波(需稳定容值与高可靠性);
  5. 车载电子:部分高压辅助电路(如车载充电系统)滤波。

六、品牌与可靠性保障

三环电子(CCTC)为该型号提供可靠保障:

  1. 认证齐全:通过ISO9001、IATF16949(汽车级)、RoHS 2.0、REACH等认证;
  2. 一致性好:自动化生产工艺,批次间容值、耐压偏差极小;
  3. 可靠性测试:通过高温寿命(125℃/1kV/1000小时)、温度循环(-55~125℃/1000次)等测试,失效率低;
  4. 环保合规:无铅、无镉,符合欧盟环保指令。

七、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即800V),避免过应力失效;
  2. 温度适配:确认应用环境温度在-55~125℃内,超出需换X8R等介质;
  3. 精度需求:若需±5%精度,可选同封装K5级产品;
  4. 焊接防护:回流焊温度不超260℃,防止介质开裂。

该型号凭借平衡的性能与性价比,成为中高压MLCC领域的主流选择,可满足多数工业级与商业级电路需求。

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
