CGA0402C0G121J500GT 多层陶瓷电容产品概述

一、产品核心参数解析

该产品为HRE(芯声)品牌0402封装多层陶瓷电容,核心参数完全匹配高频稳定型电路需求,具体如下:

  • 容值与精度:标识“121J”对应标称容值120pF,精度±5%(EIA代码“J”明确表示±5%误差范围);
  • 额定电压:50V直流额定电压,满足常规低压电子系统的耐压要求,避免过压损坏风险;
  • 温度系数:采用C0G(NP0)特性,是陶瓷电容中温度稳定性最优的类别,容值随温度变化极小;
  • 封装规格:0402英制封装(公制1005),尺寸为1.0mm×0.5mm×0.5mm(长×宽×高),适配高密度贴装设计。

二、关键性能特性

  1. 极优温度稳定性
    C0G型电容在-55℃至+125℃的宽温度范围内,容值变化率≤±30ppm/℃,几乎不受环境温度波动影响,是对容量精度要求极高场景的核心选择;
  2. 高频低损耗
    陶瓷材料的高频特性优异,ESR(等效串联电阻)低(典型值≤10mΩ@1kHz),适合射频、微波电路的滤波、耦合及谐振应用;
  3. 无极性与抗干扰
    多层陶瓷结构无极性设计,安装无需区分正负极,且抗电磁干扰能力强,可有效抑制电路中的杂波;
  4. 小型化适配
    0402封装体积小,可将电路空间占用降低30%以上,符合消费电子、通信设备的轻薄化趋势。

三、典型应用场景

该电容的性能与封装特性使其适用于多个领域的高频稳定电路:

  • 射频通信领域:蓝牙、WiFi、5G基站的射频前端滤波、信号耦合,以及无线模块的谐振回路;
  • 消费电子领域:智能手机、平板电脑、智能穿戴设备的高频电路去耦、EMI滤波(如摄像头模组、WiFi模块);
  • 工业控制领域:小型传感器模块、PLC(可编程逻辑控制器)的信号调理电路,满足-40℃~+85℃宽温环境下的稳定工作;
  • 医疗电子领域:低功耗医疗设备(如便携监护仪、血糖仪)的信号滤波,符合对低损耗、高可靠性的严格要求。

四、封装与可靠性保障

  1. 环保封装工艺
    采用HRE自主研发的多层陶瓷叠层工艺,端电极使用镍/锡镀层,符合RoHS、REACH环保标准,无铅焊接兼容性好,可适配回流焊、波峰焊等常规贴装工艺;
  2. 可靠性验证
    产品通过多项行业标准测试:高温存储(125℃×1000h)、温度循环(-55℃~+125℃×1000次)、湿度老化(85℃/85%RH×500h),确保恶劣环境下的长期稳定;
  3. 机械性能
    0402封装抗弯强度≥100MPa,可承受贴装过程中的轻微机械应力,生产损坏率低于行业平均水平。

五、品牌与品质优势

HRE(芯声)作为国内专注陶瓷电容研发生产的品牌,该产品具备以下优势:

  • 一致性管控:自动化生产+在线检测,容值、精度一致性优于±3%(行业标准±5%),适合批量采购;
  • 定制化支持:可根据客户需求调整电压(如25V、100V)、容值精度(如±1%)等参数;
  • 售后保障:提供样品测试、应用方案优化,批量客户可享受2年质保及品质追溯服务。

该产品凭借稳定的C0G特性、小型化封装及高可靠性,成为高频电子系统的高性价比选择,可广泛适配消费电子、通信、工业等多领域应用。

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
