TCC0805COG221J500BT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

该型号为三环电子(CCTC) 出品的贴片多层陶瓷电容(MLCC),是针对高频稳定、精度要求较高的电路设计的通用型元件。型号编码解析清晰:

  • TCC:三环电子品牌代码;
  • 0805:英制贴片封装(公制对应2012);
  • COG:温度系数(IEC标准,对应EIA NP0);
  • 221:容值代码(22×10¹=220pF);
  • J:精度等级(±5%);
  • 500:额定直流电压(50V);
  • BT:生产批次/工艺后缀(三环内部编码)。

二、关键性能参数

核心参数围绕稳定性、精度、适用场景设计,具体如下:

  1. 容值与精度:标称220pF,精度±5%(J级),满足多数精密电路的匹配需求,避免因容值偏差导致信号失真;
  2. 额定电压:直流50V,可稳定工作在0~50V范围内,无击穿风险,适配低电压电路(如3.3V/5V系统)的去耦、滤波;
  3. 温度特性:C0G材质,-55℃~+125℃宽温范围内,容值变化率≤±30ppm/℃,损耗角正切(tanδ)典型值≤0.15%(1kHz/25℃),高频下损耗极低;
  4. 封装尺寸:0805封装(长2.0±0.2mm×宽1.2±0.2mm×厚0.8±0.1mm),适配高密度PCB布局,支持小型化设备设计。

三、封装与机械规格

0805封装是电子行业通用贴片规格,机械兼容性强:

  • 端电极结构:三层复合电极(镍层+锡层+铅层/无铅锡),焊接兼容性好,可通过回流焊、波峰焊工艺;
  • 焊盘适配:匹配标准0805焊盘(焊盘宽度0.6mm,间距0.8mm),无需特殊PCB设计;
  • 机械强度:多层陶瓷结构抗弯折性较好,生产过程中不易开裂,贴装良率≥99.5%。

四、温度与高频性能优势

C0G材质是MLCC中温度稳定性最优的类别之一,核心优势突出:

  1. 宽温无漂移:在极端温度(如-40℃~+85℃工业环境)下,容值变化可忽略,避免电路参数偏移;
  2. 低损耗高频特性:100MHz高频下tanδ仍≤0.2%,减少信号损耗,适合射频(RF)电路的耦合、滤波;
  3. 无极性设计:无需区分正负极,安装便捷,可用于双向信号传输电路。

五、典型应用场景

结合性能特点,该型号广泛用于以下领域:

  1. 射频通信:蓝牙/WiFi模块的带通滤波器、晶体振荡器负载电容、4G/5G基站的射频耦合电容;
  2. 精密模拟电路:运算放大器的滤波电容、传感器信号调理电路的匹配电容;
  3. 工业控制:PLC、变频器的宽温环境滤波电容、电机驱动电路的去耦电容;
  4. 消费电子:智能手机音频电路滤波、平板电脑射频前端组件、智能穿戴设备的信号耦合;
  5. 医疗电子:低功耗监护仪的信号滤波、便携医疗设备的电源去耦(符合低干扰要求)。

六、可靠性与质量保障

三环电子作为国内MLCC主流供应商,该型号通过多项行业认证:

  1. 环保认证:符合RoHS 2.0、REACH(SVHC)标准,无铅无卤,适配绿色电子设计;
  2. 可靠性测试:经过高温存储(125℃×1000h)、温度循环(-55℃~+125℃×1000次)、湿度偏压(85℃/85%RH×500h)测试,MTBF≥10⁶小时;
  3. 批次一致性:全自动生产工艺,容值、尺寸偏差控制在规格范围内,批量采购无需担心参数波动。

七、选型与使用注意事项

  1. 选型匹配:若需更高电压(如100V),可选择同封装C0G材质的TCC0805COG221J100BT;若需更大容值(如1μF),需换用X7R材质(但温度稳定性下降);
  2. 焊接要求:回流焊温度曲线建议:预热区(150℃180℃,60120s)、回流区(210℃240℃,3060s),避免过热导致电容开裂;
  3. 储存条件:常温(15℃~35℃)、干燥(湿度≤60%)环境储存,开封后12个月内使用,避免端电极氧化;
  4. 静电防护:MLCC对静电敏感,操作时需佩戴防静电手环,使用防静电工作台,避免静电击穿。

该型号凭借稳定的性能、紧凑的封装和可靠的质量,成为高频电路、精密模拟电路的优选元件,适配多领域电子设备的设计需求。

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
