CGA1210X5R107M100RT 产品概述

一、产品简介

CGA1210X5R107M100RT 是 HRE(芯声)品牌的一款高容量贴片多层陶瓷电容(MLCC),额定参数为 100 μF ±20%,额定电压 10 V,介质类型为 X5R,封装为 1210(约 3.2 mm × 2.5 mm)。该产品面向需要大容量去耦、滤波和能量存储的电源线路,兼顾体积与性能,适合消费电子、电源模块及通信设备等场景。

二、主要参数

  • 容量:100 μF(标称)
  • 精度:±20%(M)
  • 额定电压:10 V
  • 介质:X5R(温度范围 -55°C 至 +85°C,典型允许偏差 ±15%)
  • 封装:1210(近似尺寸 3.2 mm × 2.5 mm)
  • 极性:无(陶瓷电容为无极性器件)
  • 包装:卷带(Reel)适用于自动贴片生产线

三、性能特点

  • 高体积容量:在 1210 尺寸下实现 100 μF 的电容,有利于减小 PCB 面积并替代若干并联小容量器件。
  • 低等效串联电阻(ESR)与低等效串联电感(ESL):相较于电解电容,MLCC 在高频下表现更好,适合瞬态响应与高频去耦。
  • 宽温度工作区间:X5R 介质支持 -55°C 至 +85°C 的温度范围,满足一般电子设备的环境要求。
  • 无极性、可靠性高:陶瓷结构无电解液泄露风险,适合长寿命应用。

注意事项:X5R 属于 II 类介质,存在明显的温度系数、直流偏压效应和老化现象。实际工作电压下(尤其接近额定电压时)电容值会显著降低,应在设计阶段考虑余量或并联使用。

四、典型应用

  • 电源去耦与旁路:单个或并联使用以降低电源纹波、提升瞬态响应。
  • DC-DC 转换器输入/输出滤波:在空间受限且要求快速响应的稳压模块中常用。
  • 便携式与消费电子设备:为 3.3 V、5 V 等低压轨提供局部储能与滤波。
  • 通信与测量设备局部电源稳压:用于抑制高频噪声和瞬态冲击。

五、设计与使用建议

  • 考虑直流偏压(DC bias):X5R 在施加直流电压后电容会下降,10 V 额定器件在 3.3 V/5 V 工作点下仍会有一定损失,建议在设计时预留裕量或通过并联多只电容补偿实际容量。
  • 并联策略:为减少 ESR、增加总容量并改善频率响应,可并联 1–2 只同型号或搭配小容量高频电容(如 0.1 μF、1 μF)。
  • 机械应力防护:1210 尺寸相对较大,容易在波峰/回流焊或板弯曲时产生裂纹。推荐采用合适的大地铜箔回流、避免过度靠近板边,按照厂商建议的焊盘设计与丝印放置。
  • 回流焊温度规范:遵循无铅回流曲线,避免超温,完成回流后允许自然冷却以减少热冲击。
  • 老化与恢复:X5R 会发生随时间的电容衰减(老化),加热至一定温度可部分恢复电容值,设计时应考虑长期漂移。

六、品质与采购建议

  • 建议向 HRE(芯声)或正规授权经销商采购,以保证器件来源与品质一致性。
  • 在关键设计上,建议向供应商索取器件数据手册、典型频率/温度/偏压曲线与可靠性测试报告,进行样片试验以确认实际工作条件下的有效电容与电气性能。
  • 对于批量生产,建议先通过可靠性验证(如热循环、机械应力测试与焊接兼容性测试)以降低返修风险。

总结:CGA1210X5R107M100RT 是一款在有限空间内提供高容量、低 ESR 的 MLCC,可显著提升电源瞬态响应与去耦效果。但在实际使用中需考虑 X5R 的直流偏压和老化特性,合理布局与必要的并联策略能有效发挥其性能。

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.
