CSA0402C0G120J500GT 多层陶瓷贴片电容(MLCC)产品概述

CSA0402C0G120J500GT是芯声(HRE)品牌推出的高频高精度多层陶瓷贴片电容(MLCC),专为对温度稳定性、精度要求较高的电子电路设计,广泛适配射频通信、精密模拟、小型化设备等场景。以下从核心属性、参数、性能等维度展开概述。

一、产品基本属性

该产品属于高频稳定型MLCC,采用贴片式封装,核心定位为中低压(50V DC)、高精度(±5%)、宽温稳定的信号/电源处理元件。型号中各代码含义明确:

  • CSA:芯声高频MLCC系列标识;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸);
  • C0G:温度系数代码(对应国际标准NP0,温度特性极稳定);
  • 120:容值标识(12×10⁰=12pF);
  • J:精度等级(±5%);
  • 500:额定电压(50×10⁰=50V DC);
  • GT:封装/批次辅助标识。

二、核心技术参数详解

  1. 容值与精度:标称容值12pF,精度±5%(J级),满足多数精密电路对容值一致性的要求,避免因容值偏差导致的信号失真;
  2. 温度系数:C0G(NP0),温度系数≤±30ppm/℃(-55℃~+125℃范围内),容值随温度变化极小,是高频电路频率稳定性的关键保障;
  3. 额定电压:直流50V,适用于中低压信号处理及电源滤波场景,需注意:MLCC额定电压为直流值,交流应用需按“额定电压×0.7”降额;
  4. 介电特性:C0G材料介电常数(εr)约10~100,损耗角正切(tanδ)≤0.001(1kHz/25℃),高频损耗极低,可减少信号传输中的能量损耗;
  5. 工作温度范围:-55℃~+125℃,覆盖工业级及消费电子常见温区,适配极端环境下的稳定工作。

三、封装与尺寸规格

采用0402封装(公制对应1005,即1.0mm×0.5mm),具体尺寸参数(典型值):

  • 长度:1.0±0.1mm;
  • 宽度:0.5±0.1mm;
  • 厚度:0.5±0.1mm;
  • 焊盘间距:0.4±0.1mm。

封装结构为多层陶瓷叠层:由陶瓷介质层(C0G材料)与镍基内电极交替叠压,经高温烧结后形成,外部电极采用镍-锡镀层,适配回流焊、波峰焊等主流贴片工艺,焊接兼容性强。

四、性能特点与优势

  1. 温度稳定性优异:C0G特性使容值受温度、电压影响极小,适合对频率稳定性要求高的振荡、滤波电路,如晶体振荡器(XO)、压控振荡器(VCO);
  2. 高频损耗低:低tanδ及高Q值(品质因数),可有效减少射频信号的传输损耗,适配WiFi、5G基站等射频通信场景;
  3. 小体积高集成:0402封装体积紧凑,能有效降低电路尺寸,满足智能穿戴、蓝牙耳机等小型化设备的空间需求;
  4. 精度与可靠性平衡:±5%精度覆盖多数工业级、消费电子场景,陶瓷材料抗老化、抗机械应力性能优于电解电容,长期使用容值漂移小;
  5. 环保合规:采用无铅电极镀层,符合RoHS 2.0、REACH等全球环保标准,适配出口及绿色产品设计需求。

五、典型应用场景

  1. 射频通信领域:手机、基站、WiFi模块中的信号滤波、耦合、匹配网络,保障信号传输的稳定性;
  2. 高频振荡电路:晶体振荡器、锁相环(PLL)的谐振电容,避免温度变化导致的频率偏移;
  3. 精密模拟电路:传感器信号调理、运算放大器滤波、基准电压源去耦,减少噪声干扰;
  4. 小型化电子设备:智能手表、TWS耳机、便携医疗设备的电源滤波及信号耦合,适配紧凑空间;
  5. 工业控制电路:PLC、伺服系统中的低噪声信号处理,适配-55℃~+125℃的宽温环境。

六、可靠性与质量保障

  1. 品牌背书:芯声(HRE)拥有10余年MLCC研发生产经验,产品通过ISO 9001、IATF 16949(汽车级)等质量体系认证,产能稳定;
  2. 可靠性测试:符合IEC 60384-1、JIS C 5102等国际标准,通过高温存储(125℃/1000h)、温度循环(-55℃~+125℃/1000次)、湿度测试(85℃/85%RH/1000h)等验证;
  3. 长期稳定性:C0G材料容值漂移率≤0.5%(1000h/125℃),抗老化性能优异,可满足设备5年以上的使用寿命要求;
  4. 工艺一致性:采用自动化叠层、烧结工艺,批量产品参数一致性高,降低电路设计与生产中的调试风险。

CSA0402C0G120J500GT凭借稳定的温度特性、高精度及小体积优势,成为高频精密电路的高性价比选择,适配多领域电子设备的升级与迭代需求。

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
