CGA0402C0G240F500GT 多层陶瓷电容(MLCC)产品概述

一、产品基本定位与身份标识

CGA0402C0G240F500GT是国内MLCC厂商HRE(芯声)推出的高频高精度通用型多层陶瓷电容,核心面向对容值稳定性、精度要求严苛的电子设计场景。产品以0402英制封装(公制1005尺寸)为载体,整合C0G(NP0)温度系数材质、24pF标称容值、±1%精度及50V额定电压等参数,是便携设备、射频通信、精密仪器等领域的高性价比方案。

二、核心技术参数深度解析

  1. 容值与精度:标称容值24pF,精度±1%——属于MLCC“高精度级”,远高于常规±5%/±10%通用产品,可避免容值偏差对电路匹配、滤波效果的影响(如射频匹配网络中,容值偏差1%可能导致信号损耗增加0.5dB以上)。
  2. 温度系数:C0G(NP0)——MLCC温度稳定性最优材质,-55℃~125℃宽温范围内,容值变化率仅±30ppm/℃(即每1℃变化,容值偏差≤0.00072pF),且无老化效应,长期使用容值保持稳定。
  3. 额定电压:50V DC——满足中低压电路需求,实际应用需注意:峰值电压不得超过额定值,建议留10%-20%余量(如工作电压控制在40V以内)。
  4. 封装尺寸:0402英制(1.0mm×0.5mm×0.5mm)——小型化封装,适配高密度PCB设计,尤其适合便携设备(如智能手表)的紧凑布局。

三、产品核心特性与应用优势

  1. 超稳定温度特性:C0G材质的零漂移特性,使其成为射频匹配网络、精密滤波电路首选——例如手机射频前端的LC匹配电路中,温度变化时容值稳定,可避免信号频率偏移、损耗增大。
  2. 高精度容值保障:±1%精度满足医疗电子、测试仪器严苛要求——如心电图机信号滤波电路,容值偏差会直接影响信号采集准确性,该产品可确保滤波特性稳定。
  3. 小型化与高密度集成:0402封装缩小PCB面积,适配TWS耳机、运动手环等便携设备,同时支持多电容并联/串联的高密度布局。
  4. 高可靠性与长寿命:HRE芯声的叠层精度、电极材料优化工艺,确保产品在振动、宽温环境下的可靠性,符合工业级、医疗级基本要求。
  5. 低损耗特性:C0G材质损耗角(tanδ)≤0.0002(1kHz下),适合2.4GHz/5GHz高频信号传输,减少信号能量损耗。

四、典型应用场景梳理

  1. 射频通信:手机、路由器、无线耳机的射频前端(匹配网络、滤波、耦合电路);
  2. 精密仪器:示波器、信号发生器、频谱分析仪的信号调理电路;
  3. 医疗电子:监护仪、心电图机、超声设备的信号滤波与电源滤波;
  4. 工业控制:PLC、传感器接口、工业物联网节点的信号滤波;
  5. 消费便携:智能手表、运动手环、TWS耳机的电源与信号电路。

五、选型与使用注意事项

  1. 电压余量:实际工作电压(含纹波、峰值)不得超过50V DC,避免过压损坏;
  2. 温度范围:C0G适用-55℃~125℃,极端高温场景需换X7R等高温材质;
  3. 精度匹配:普通电源滤波可选±5%精度产品降低成本,精密场景保留±1%;
  4. 封装兼容性:0402封装需匹配0.6mm×0.3mm焊盘,避免虚焊或应力集中;
  5. 货源验证:通过HRE正规渠道采购,避免假冒产品影响电路可靠性。

该产品以“高精度+高稳定+小型化”为核心竞争力,覆盖多领域通用需求,是电子设计中替代进口高精度MLCC的高性价比选择。

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
