CGA0805X7R104K101MT 产品概述

一、主要参数

  • 名称:CGA0805X7R104K101MT(HRE 芯声)
  • 类型:贴片多层陶瓷电容(MLCC)
  • 容值:100 nF(0.1 µF)
  • 精度:±10%(K)
  • 额定电压:100 V DC
  • 温度特性:X7R(–55°C 至 +125°C,电容随温度变化在典型范围内控制)
  • 封装:0805(约 2.0 mm × 1.25 mm)

二、产品特点

  • 高耐压:100 V 额定电压,适用于中高电压直流回路的旁路与滤波需求。
  • 容量密度高:在 0805 小封装下提供 100 nF,便于在空间受限的电路中实现必要的去耦与滤波。
  • 温度稳定性良好:X7R 型介质在宽温区间内保持相对稳定的电容特性,适合工业级环境。
  • 低等效串联电阻(ESR)和低寄生电感,适合高频去耦与快速纹波抑制。
  • 表面贴装,兼容标准回流焊流程,适合批量自动化贴装生产。

三、典型应用

  • 开关电源输入/输出侧去耦与滤波(DC-DC、AC-DC)
  • 工业与汽车电子中 48V、60V 及更高电压分配线的旁路与降噪(需注意工作电压下的 DC-bias 影响)
  • 电机驱动、逆变器与功率模块局部滤波
  • 一般数字/模拟电路去耦(靠近器件放置以获得最佳效果)
  • 不推荐用于高精度计时或谐振回路(X7R 存在温度与电压依赖的电容漂移)

四、封装与焊接建议

  • 封装 0805(2012 公制)占板面积小,建议在布局时将去耦电容尽量靠近电源引脚,焊盘短且宽以降低寄生。
  • 回流焊:兼容标准回流曲线(遵循 J-STD-020/IPC 指南),峰值温度按板厂工艺设定(常见峰值 245–260°C)。
  • 防裂注意:陶瓷电容对机械应力敏感,过度挤压或 PCB 弯曲可能导致裂纹。对高振动或热循环环境,考虑加固或选用抗裂设计。
  • 清洗与回流后检查焊点完整性,必要时进行 X 射线或外观检测。

五、可靠性与使用注意

  • DC-bias 特性:X7R 在高直流偏置下会出现显著电容降额,实际工作电压下的有效电容应在电路设计时验证。
  • 温度依赖:虽然 X7R 温区宽,但温度与频率仍会影响电容值,关键电路请进行环境测试。
  • 存储与烘烤:遵循供应商包装和湿敏等级说明,必要时按 IPC/JEDEC 建议预烘以避免回流焊时的湿爆。
  • 机械筛选:对于振动或机械应力较大的场合,应在方案评估中加入可靠性测试(热冲击、振动、机械冲击)。

六、订购与等效建议

  • 品牌:HRE(芯声)提供该型号,适合批量采购与工业应用。
  • 选型提示:若对温度/电压稳定性要求更高,可考虑 C0G/NP0 系列(但价格与容值限制);若对体积要求更小,可选 0603 或 0402,但注意额定电压与容值的匹配。
  • 备货与替代:在设计替代元件时,关注容值、耐压、介质类型与封装一致,并在样板上验证 DC-bias 与温漂行为。

以上为 CGA0805X7R104K101MT 的产品概述,覆盖关键电气参数、适用场景与实际设计时的注意要点。若需详细电气曲线(如频率响应、DC-bias 曲线、ESR/ESL 数据)或封装机械图纸,可进一步提供以便精确匹配设计要求。

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
