TCC0402COG181J500AT 贴片电容(MLCC)产品概述

TCC0402COG181J500AT是三环电子(CCTC)推出的0402封装C0G系列多层陶瓷贴片电容(MLCC),专为对容值稳定性、精度要求严苛的高频精密电路设计。核心参数为180pF容值、±5%精度、50V额定电压,兼具小体积、低损耗、宽温稳定等特性,广泛适配消费电子、射频通信、工业控制等领域。

一、产品核心基础参数

关键技术参数明确,可直接匹配电路设计需求:

  • 容值与精度:标称容值180pF(标识代码“181”,即18×10¹pF),精度等级±5%(国际标识“J”档),满足多数精密电路的容值偏差要求;
  • 电气额定值:50V直流额定电压,可稳定支撑中等功率密度的电路工作;
  • 温度特性:C0G(NP0)温度系数(陶瓷电容中稳定性最优类别),-55℃~125℃范围内容值波动≤±30ppm/℃;
  • 封装规格:0402英制贴片封装(对应公制1005,尺寸约1.0mm×0.5mm),符合表面贴装工艺标准;
  • 合规性:符合RoHS 2.0及无铅焊接要求,适配绿色电子制造流程。

二、核心性能优势

相比普通X7R/Y5V材质电容,该产品核心优势集中在稳定性与高频特性:

  1. 极致温度稳定性:C0G无铁电效应,容值不随温度、电压变化衰减,适合医疗仪器、测试设备等对精度长期稳定的场景;
  2. 低损耗高频适配:介质损耗角正切值(tanδ)≤0.15%(1kHz下),等效串联电阻(ESR)低,减少高频信号能量损耗,适配射频前端、振荡电路;
  3. 小体积高密度:0402封装压缩电路布局空间,满足智能手机、可穿戴设备等小型化产品需求;
  4. 宽温工作范围:-55℃~125℃覆盖工业级、车规级(部分场景)的环境要求。

三、封装与制造工艺

三环电子采用成熟的多层陶瓷叠层工艺保障产品一致性:

  • 封装结构:矩形贴片设计,两端镍/锡镀层电极,兼容回流焊、波峰焊(需适配夹具);
  • 介质与电极:高纯度C0G陶瓷介质+银钯合金(Ag-Pd)电极,抗氧化性优于纯银,长期可靠性更高;
  • 工艺控制:全自动叠层、激光打孔、共烧等工艺,确保介质层均匀、电极对齐,容值偏差严控±5%以内。

四、典型应用场景

该电容特性适配多领域针对性应用:

  1. 射频通信:手机、5G基站、蓝牙模块的射频前端滤波、阻抗匹配网络;
  2. 精密电子:医疗监护仪、示波器、信号发生器的信号调理电路;
  3. 消费终端:智能手表、无线耳机的高频振荡电路;
  4. 工业控制:PLC、传感器节点的电源滤波、噪声抑制。

五、可靠性与质量保障

三环对产品可靠性管控符合行业高标准:

  • 可靠性测试:通过IEC 60384-14标准的高低温循环(1000次)、湿度老化(1000小时)、振动冲击测试,失效率≤10Fit;
  • 质量体系:具备ISO 9001、IATF 16949认证,产品一致性管控严格;
  • 长期稳定:C0G材质无老化现象,容值可保持10年以上无明显衰减。

六、选型与使用注意事项

为确保性能发挥,需注意以下要点:

  1. 电压余量:实际工作电压≤37.5V(额定电压75%),避免过压击穿;
  2. 温域适配:超出-55℃~125℃需更换X7R等其他材质;
  3. 焊接控制:回流焊峰值温度230℃~250℃(持续≤10秒),避免过温开裂;
  4. 静电防护:MLCC为静电敏感元件,生产测试需ESD防护。

总结

TCC0402COG181J500AT是一款高稳定、高精度、小体积的C0G系列MLCC,适配对容值稳定性要求严苛的高频精密电路。三环电子的工艺管控与质量认证,保障了产品在消费电子、工业控制等领域的可靠应用,是小型化高性能电路设计的理想选择。

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
