HRE CGA1210C0G333J631RT 多层陶瓷电容产品概述

一、产品基本参数与型号解读

该型号为HRE(芯声)旗下Class 1高压多层陶瓷电容(MLCC),型号各部分含义清晰:

  • CGA:HRE高压MLCC系列标识;
  • 1210:英制封装尺寸(对应公制3.2mm×2.5mm);
  • C0G:温度系数代码(EIA标准,对应IEC NP0,容值温度漂移≤±0.1%@-55℃~125℃);
  • 333:容值代码(33×10³pF=33nF);
  • J:精度等级(±5%);
  • 631:额定电压(63×10¹V=630V DC);
  • RT:包装/工艺后缀(卷带式包装,符合EIA 481标准)。

核心参数表如下:

参数项 具体数值 型号 CGA1210C0G333J631RT 品牌 HRE(芯声) 容值 33nF(33×10³pF) 精度 ±5%(J级) 额定电压(UR) 630V DC 温度系数 C0G(NP0) 封装尺寸 1210(3.2mm×2.5mm) 工作温度范围 -55℃ ~ +125℃

二、核心性能优势

  1. 极致温度稳定性
    C0G介质属于无老化效应的Class 1陶瓷,容值随温度变化极小(典型值±0.1%以内),且频率特性平坦,可替代传统薄膜电容用于对容值精度要求苛刻的场景。

  2. 高压小体积突破
    常规1210封装电容额定电压多≤250V,该型号通过优化叠层工艺实现630V高压,可压缩高压电路PCB布局空间30%以上,适配紧凑系统设计。

  3. 低损耗高Q值
    损耗角正切(tanδ)典型值≤0.0001@1kHz,等效串联电阻(ESR)在100MHz下仍保持<1Ω,适合射频信号耦合、匹配网络等低损耗场景,提升信号传输信噪比。

  4. 工业级可靠性
    多层陶瓷叠层结构抗振动冲击(符合IPC-9701,10~2000Hz/10g),额定条件下平均无故障时间(MTBF)超10⁶小时,满足光伏、工业变频器等连续工作场景。

三、典型应用场景

  1. 工业高压电源
    开关电源输入/输出滤波、EMI抑制,替代电解电容可降低电源体积(如光伏逆变器、工业变频器)。

  2. 精密测量仪器
    示波器、信号发生器的信号调理电路,利用C0G稳定性避免容值漂移导致的测量误差。

  3. 通信射频前端
    基站射频模块的信号耦合、阻抗匹配,低损耗特性减少信号衰减(覆盖2G/3G/4G频段)。

  4. 医疗设备高压电路
    医用CT、MRI的高压电源滤波,无极性特性避免电解电容极性错误风险,提升设备安全性。

四、可靠性与环境适应性

  1. 极端温度耐受
    -55℃~+125℃范围内,容值变化≤±0.15%,满足工业级、车载级(若AEC-Q200认证)温度要求。

  2. 耐候性验证
    通过IEC 60068-2-66(湿热1000h)、IEC 60068-2-52(盐雾96h),湿度95%RH环境下性能无衰减。

  3. 机械可靠性
    焊接后抗弯曲能力符合IPC-A-610(弯曲半径20mm/180°),可承受电路板轻微形变;抗振动满足GJB 150.25A(15g/20~2000Hz)。

五、选型与应用注意事项

  1. 电压降额
    实际工作电压建议≤额定电压的80%(即≤504V),避免长期过应力加速老化。

  2. 焊接工艺
    回流焊峰值温度≤245℃(时间≤30s),手工焊温度≤350℃(时间≤3s),防止热应力损坏陶瓷结构。

  3. 精度匹配
    若需更高精度(如计量级),需选择B级(±0.1%),该型号仅提供J级(±5%)。

  4. 散热设计
    虽损耗极低,但高压工作时仍需预留散热空间,避免与发热元件近距离布置。

该型号兼顾高压、小体积与高稳定性,是工业、通信、医疗领域高压精密电路的高性价比选择,可有效替代传统薄膜电容或高压电解电容。

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
