TCC0402COG820J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与核心参数

TCC0402COG820J500AT是三环电子(CCTC)针对高频精密电路推出的0402封装MLCC,核心定位为“小型化+高稳定”,核心参数明确:

  • 容值:82pF(标识代码“820”,即82×10⁰pF);
  • 精度:±5%(行业J档,满足精密电路对容值一致性的要求);
  • 额定电压:50V DC(覆盖多数消费电子、通信电路的工作电压范围);
  • 温度系数:C0G(NP0类,MLCC中温度稳定性最优的介质类别);
  • 封装:0402(英制尺寸,对应公制1005,体积约1.0mm×0.5mm×0.5mm)。

二、关键性能特性

  1. 极致温度稳定性
    C0G介质的温度系数≤±30ppm/℃,在-55℃~125℃全温区范围内,容值变化不超过±0.03%(对比X7R类容值变化可达±15%),完全适配射频、精密模拟电路对容值漂移的严苛要求。

  2. 低损耗与高频兼容
    介质损耗角正切值(tanδ)≤0.15%(1kHz条件下),适合2.4GHz、5GHz等高频信号传输,可用于滤波器、振荡器的耦合/去耦环节,信号损耗极小。

  3. 高可靠性与无极性
    采用镍基电极(符合RoHS环保标准)+多层陶瓷叠层结构,无极性设计简化电路布线;长期工作下容值漂移≤±1%(1000小时高温负载测试),抗电涌能力满足IEC 60384-14标准。

  4. 小型化集成优势
    0402封装体积仅为0.04×0.02英寸,适配智能手机、可穿戴设备、IoT终端等高密度贴装需求,可有效缩小电路板面积。

三、封装与工艺优势

三环电子针对该产品采用高精度叠层工艺:

  • 介质层厚度控制精度达±1μm,确保批量生产的容值一致性;
  • 端电极采用“镍底层+锡铅/无铅表层”结构,焊接兼容性强,回流焊后剪切强度≥2N(符合SMT自动化生产要求);
  • 封装尺寸公差严格控制在±0.05mm以内,适配富士、西门子等主流贴片机的精准定位。

四、典型应用场景

该产品因“小型化+高稳定”特性,广泛应用于以下领域:

  1. 通信设备:2G/3G/4G/5G基站射频模块、Wi-Fi模块的滤波器、耦合器;
  2. 消费电子:智能手机主板高频去耦、蓝牙模块振荡电路;
  3. IoT终端:智能家居传感器、智能手表信号调理电路;
  4. 工业控制:小型PLC模拟量输入/输出滤波电路;
  5. 医疗设备:便携式监护仪低噪声电路。

五、可靠性与环境适应性

  1. 温湿度耐受:-55℃~125℃工作范围,85℃/85%RH环境下1000小时测试,容值变化≤±1%;
  2. 焊接兼容性:回流焊峰值温度260℃(10秒内)无性能衰减,兼容波峰焊;
  3. 机械强度:抗振动(10~2000Hz,加速度1.5g)、抗弯折(10mm曲率下无开裂);
  4. 长期寿命:常温下工作寿命≥10万小时,高温负载下(125℃)寿命≥1万小时。

六、选型与替代参考

  • 同参数直接替代:村田GRM1555C1H820JA01D、三星CL05B820JB5NNNC(均为0402封装C0G820J50V);
  • 参数调整替代:若精度降至±10%(K档),可选择同封装82pF±10%的X7R类产品(如CCTC TCC0402X7R820K500AT,需注意温度稳定性下降);
  • 封装调整:空间允许时,可替换为0603封装同参数产品(如CCTC TCC0603COG820J500AT),但体积增大1.5倍左右。

该产品凭借高稳定、小型化特性,成为消费电子与通信领域高频电路的主流选型之一,适配多数中高端电子设备的设计需求。

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
