TCC0805COG471J501BT 贴片多层陶瓷电容(MLCC)产品概述

TCC0805COG471J501BT是三环电子(CCTC)推出的一款中高压精密贴片多层陶瓷电容(MLCC),采用0805(英制2012)封装,核心参数匹配高频、精密及中高压应用场景,是工业控制、通信设备等领域的常用基础元件。

一、产品基本信息

该型号为三环电子常规系列MLCC,核心标识明确:

  • 品牌:三环电子(CCTC),国内专业电子元器件制造商,产品覆盖消费电子、工业、通信等多领域;
  • 封装:0805(英制尺寸,对应公制2012,即长2.0mm×宽1.2mm),属于小尺寸常规贴片封装,适配主流表面贴装生产线;
  • 类型:多层陶瓷电容(MLCC),通过多层陶瓷介质叠层+电极烧结而成,容值稳定、体积小。

二、核心性能参数

TCC0805COG471J501BT的关键参数聚焦温度稳定性、容值精度及电压耐受,具体如下:

1. 容值与精度

  • 标称容值:470pF(采用3位编码“471”表示:前两位为有效数字47,第三位为倍率10¹,即47×10¹=470pF);
  • 精度等级:±5%(标识“J”),属于工业级常规精度,满足大多数精密电路需求。

2. 额定电压与温宽

  • 直流额定电压:500V,可支持中高压场景下的滤波、耦合等功能;
  • 工作温度范围:-55℃~+125℃,覆盖工业级宽温需求,适应极端环境。

3. 温度系数与损耗

  • 温度系数:C0G(国际标准,对应国内NP0),为温度补偿型陶瓷介质,在-55℃~+125℃范围内,容值变化率≤±30ppm/℃(即温度每变化1℃,容值变化不超过0.003%),无明显老化效应;
  • 损耗角正切(DF):典型值≤0.15%(1kHz测试条件),低损耗特性适合高频信号传输,减少信号衰减。

4. 绝缘性能

  • 绝缘电阻(IR):≥10¹⁰Ω(25℃、500V直流条件),高绝缘性避免漏电流影响电路稳定性。

三、材料与封装特性

1. 陶瓷介质材料

采用C0G型低温烧结陶瓷,其成分以钛酸钡为基础,掺杂稳定元素,实现极低温度系数、低损耗,且无压电效应,适合高频电路(如射频、微波)。

2. 封装与电极

  • 封装尺寸:0805(2.0×1.2×0.5mm,典型厚度),表面贴装端电极采用镍/锡(Ni/Sn)镀层,适配回流焊、波峰焊工艺,焊接可靠性高;
  • 内部电极:采用银钯(Ag-Pd)合金,烧结后与陶瓷介质结合紧密,耐温性好,避免高温焊接时电极氧化或脱落。

四、典型应用场景

基于其参数特性,TCC0805COG471J501BT主要应用于以下领域:

1. 高频通信设备

  • 射频(RF)模块、无线局域网(WLAN)、蓝牙设备:利用C0G的低损耗、高温度稳定性,实现信号耦合、滤波,避免信号失真;
  • 卫星通信、微波电路:宽温范围满足户外极端环境需求。

2. 工业控制与仪器

  • PLC(可编程逻辑控制器)、传感器接口电路:中高压耐受(500V)满足工业电源滤波,±5%精度保障信号采集准确性;
  • 精密测量仪器(示波器、信号发生器):稳定容值确保测量精度。

3. 中高压电源电路

  • 开关电源的EMI滤波、高压耦合:500V额定电压适配中高压电源设计,低损耗减少电源效率损耗;
  • LED驱动电源:辅助滤波,提升电源稳定性。

五、选型与使用注意事项

1. 电压降额设计

实际工作电压建议不超过额定电压的80%(即400V),避免长期高压导致陶瓷介质老化,延长产品寿命。

2. 焊接工艺要求

  • 回流焊温度曲线:峰值温度≤245℃,升温速率≤3℃/s,降温速率≤2℃/s,避免过温导致陶瓷开裂;
  • 波峰焊:焊接时间≤3s,温度≤240℃,防止端电极镀层熔化或脱落。

3. 静电防护

MLCC为静电敏感元件(ESD等级通常为Class 1),操作时需佩戴防静电手环,工作台接地,避免静电击穿内部电极。

4. 存储条件

常温干燥环境(温度1535℃,湿度40%60%),存储周期不超过12个月;开封后未使用的元件需密封保存,避免受潮影响焊接性能。

六、品牌与质量保障

三环电子(CCTC)是国内MLCC领域的主流厂商,该型号符合以下标准:

  • 环保认证:RoHS 2.0、REACH,无铅无镉;
  • 质量管理:通过ISO9001认证,批量产品一致性好;
  • 可靠性验证:经过高温老化、温度循环等可靠性测试,满足工业级应用要求。

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.
