TCC0805COG470J251BT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性

TCC0805COG470J251BT是三环电子(CCTC)推出的0805封装贴片多层陶瓷电容(MLCC),属于C0G(NP0)温度系数系列,专为对容值稳定性、高频特性要求较高的电子电路设计。产品采用表面贴装工艺,兼容主流SMT生产线,适用于工业、通信、消费电子等多领域的精密电路场景,兼具高性价比与可靠性。

二、关键性能参数详解

该产品核心参数可通过型号编码清晰解析,具体如下:

  1. 容值与精度:标称容值47pF,精度±5%(型号中“J”为行业标准精度标识,对应±5%);容值编码“470”表示前两位有效数为47,第三位“0”为10⁰,即47×10⁰=47pF。
  2. 额定电压:250V DC(型号中“251”为电压编码,前两位25,第三位“1”为10¹,即25×10¹=250V);短时间过压耐受能力≤312.5V(符合IEC 60384-14标准)。
  3. 温度系数:C0G(NP0),是MLCC中温度稳定性最优的介电材料之一,容值温度变化率≤±30ppm/℃(-55℃至+125℃范围内),介电损耗(DF)≤0.15%(1kHz/1Vrms条件下),无老化效应。
  4. 封装尺寸:0805英制封装(对应公制2012),具体尺寸为长2.0±0.2mm、宽1.25±0.2mm、厚0.8±0.1mm(典型值),端电极宽度0.3±0.1mm,适配常规SMT贴装设备。

三、封装与结构特点

  1. 多层陶瓷叠层工艺:采用高纯度钛酸钡基陶瓷介质,多层叠层设计实现高容值密度,同时保证介电性能稳定;内外电极采用镍(Ni)材料,端电极外层镀锡(Sn),符合无铅RoHS标准。
  2. 焊接兼容性:端电极结构适配回流焊、波峰焊工艺,回流焊峰值温度≤260℃(时间≤10秒),波峰焊温度≤245℃(时间≤5秒),焊接后可通过AOI、X-Ray等常规检测。
  3. 机械强度:陶瓷体与电极结合牢固,能承受SMT过程中的机械应力,耐弯折性能符合GB/T 26253标准(弯折半径≥5mm,弯折次数≥5次),降低生产过程中的损坏率。

四、典型应用场景

基于C0G的高稳定性与低损耗特性,该产品适用于以下核心场景:

  1. 高频通信电路:5G基站射频模块、WiFi6路由器、蓝牙设备中的滤波器、耦合器、振荡电路(容值稳定避免频率漂移)。
  2. 精密模拟电路:运算放大器反馈电容、数据采集系统滤波电容(容值精度直接影响信号线性度)。
  3. 电源滤波:DC-DC转换器高频纹波抑制、小信号电源滤波(避免容值变化导致滤波效果下降)。
  4. 工业与医疗设备:工业传感器、医疗监护仪等长期稳定运行场景(无老化特性降低维护成本)。

五、可靠性与环保特性

  1. 长期稳定性:C0G介电材料无老化效应,容值在工作寿命内(≥10万小时)几乎无变化;耐湿度性能符合JIS C 5102标准(95%RH/40℃环境下1000小时,容值变化≤±1%)。
  2. 环保合规:不含铅、镉、汞等有害物质,符合RoHS 2.0(2011/65/EU)及REACH法规要求,可用于出口产品。
  3. 质量认证:通过ISO 9001质量管理体系认证,基础款满足工业级可靠性要求,部分批次可适配AEC-Q200车规标准(需确认具体供货批次)。

六、选型与使用注意事项

  1. 电压降额:建议实际工作电压不超过额定电压的70%(≤175V),避免过压导致介质击穿。
  2. 温度范围:工作温度-55℃至+125℃,存储温度-40℃至+85℃(湿度≤60%RH)。
  3. 静电防护:MLCC对静电敏感,操作时需佩戴防静电手环,使用防静电包装与工作台。
  4. 机械应力:焊接后避免对电容施加过大压力或弯折,防止陶瓷体开裂。

TCC0805COG470J251BT凭借高容值稳定性、低损耗及可靠的封装设计,成为精密电子电路中替代传统薄膜电容的高性价比选择,广泛适配多领域的设计需求。

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.

Replenishment inquiry Typical RFQ workflow
