CGA0402C0G181J500GT 多层陶瓷电容产品概述

CGA0402C0G181J500GT是芯声(HRE)推出的一款0402封装C0G系列多层陶瓷电容(MLCC),针对高频、高稳定场景设计,以极小的温度漂移、低损耗为核心优势,广泛适配便携式电子、射频通信、精密仪器等领域的电路需求。

一、产品核心身份与定位

该电容属于Class I陶瓷电容(区别于侧重大容量的Class II),核心定位是“稳定优先”——优先满足容值一致性、温度/电压稳定性,而非超大容值。作为芯声C0G系列的主流型号,它适配对信号精度要求高、环境温度变化大的电路,是射频前端、精密测量等场景的高性价比选择。

二、基础电气参数详解

1. 容值与精度

  • 标称容值:180pF,采用EIA代码“181”标识(前两位18为有效数字,第三位1为10¹次方,即18×10¹=180pF);
  • 精度等级:“J”级,对应±5%,满足大多数一般精度电路需求(若需±1%高精度,可参考同系列“B”级产品)。

2. 额定电压

  • 直流额定电压:50V;
  • 交流电压注意:交流工作电压需按有效值降额(通常不超过额定直流电压的70%,即35V),避免电容击穿或性能衰减。

3. 温度系数

  • EIA分类“C0G”(对应IEC NP0),核心优势是容值随温度变化极小:典型温度系数≤±30ppm/℃(即温度每变化1℃,容值变化≤0.003%),远优于Class II的X7R(±15%),可在-55℃~125℃宽温度范围保持稳定。

三、封装与物理特性

1. 封装规格

  • 英制“0402”封装(公制1005):芯片尺寸1.0mm×0.5mm,引脚间距约0.3mm,是便携式设备的主流小型化封装;
  • 表面贴装型(SMD):无引线设计,适配高密度PCB布局,尤其适合手机、TWS耳机等紧凑产品。

2. 物理特性

  • 重量:约0.005g,抗振动性能符合IPC-9701标准,可承受一定机械应力;
  • 存储:常温干燥环境(温度0℃~40℃,湿度≤60%),避免静电损伤(MLCC为静电敏感元件)。

四、材料与性能优势

C0G材料为钛酸钡基陶瓷(含少量添加物),晶体结构在宽温度范围内无铁电相变,因此具备三大核心优势:

  1. 容值稳定性:不受温度、直流偏置电压影响,适合振荡电路、射频匹配等对容值一致性要求高的场景;
  2. 低损耗:损耗角正切(tanδ)典型值≤0.0001@1kHz,高频下信号损耗极小,适配射频、微波电路;
  3. 长期可靠性:无老化导致的容值漂移,使用寿命长(典型值≥10万小时)。

五、典型应用场景

该电容的特性使其在以下场景表现突出:

  1. 射频通信模块:蓝牙5.0/5.1、WiFi 6/6E、5G小基站的射频前端匹配(如PA输出匹配、滤波器谐振);
  2. 便携式电子:智能手机射频天线调谐、TWS耳机蓝牙模块滤波;
  3. 精密仪器:示波器信号滤波、函数发生器振荡电路;
  4. 工业控制:PLC模拟信号滤波、传感器信号调理(适配-55℃~125℃极端温度)。

六、选型与使用注意事项

  1. 电压降额:实际直流工作电压建议不超过40V(额定电压80%),避免过载老化;
  2. 焊接工艺:采用回流焊(峰值温度245℃±5℃,回流时间≤30s),避免手工焊接热冲击;
  3. 静电防护:生产/存储需防静电手环、防静电包装(ESD等级1kV~2kV);
  4. 精度匹配:若需±1%精度,选同系列“B”级产品(如CGA0402C0G181B500GT)。

CGA0402C0G181J500GT凭借“高稳定、低损耗、小型化”的核心优势,成为射频通信、便携式电子等领域的可靠选择,选型时需结合实际工作条件匹配,确保电路性能稳定。

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
