CGA0805X7R105K250MT 产品概述 — HRE(芯声) 0805 1µF ±10% 25V X7R 多层陶瓷贴片电容

一、产品简介

CGA0805X7R105K250MT 是 HRE(芯声) 系列的一款多层陶瓷贴片电容(MLCC),封装尺寸为 0805(2012 公制),标称容量 1µF,容差 ±10%,额定电压 25V,温度特性为 X7R。该型号在体积与电容容量之间实现了良好平衡,适用于对体积敏感但仍需中等稳定性和较大电容值的应用场景。

二、主要电气参数

  • 容值:1.0 µF(105 表示 1×10^5 pF = 1µF)
  • 容差:±10%(K)
  • 额定电压:25 V DC
  • 温度系数:X7R(-55°C 至 +125°C 范围内容值变化在 ±15% 以内)
  • 封装:0805(2.0 × 1.25 mm,厚度视具体工艺略有差异) 这些参数决定了器件在电源去耦、旁路与一般耦合场景中的适用性。

三、性能特点

  • 体积小、容量大:0805 封装在保持小占板面积的同时提供 1µF 的容量,适合高密度 PCB 设计。
  • 温度稳定性良好:X7R 材料兼顾容量密度与温度响应,适合大多数商用与工业温度范围应用。
  • 高频特性:MLCC 本体低等效串联电阻(ESR)和低等效串联电感(ESL),在高频去耦和滤波中表现出色。
  • 高可靠性:经过标准化的陶瓷烧结工艺,具有优良的机械强度和耐湿性能。

四、典型应用场景

  • 电源去耦与稳压模块(DC-DC 转换器输入/输出去耦)
  • 模拟与数字混合电路的旁路与滤波
  • 通信设备、消费电子、工业控制与汽车电子(符合温度要求时)
  • 移动设备、物联网模块中的体积受限设计

五、封装与包装

本产品为 0805 表面贴装封装,适配自动贴片机与回流焊工艺。常见包装形式包括卷盘(reel)供 SMT 生产线使用,包装上会标注批次、容量、耐压与封装信息,便于生产与追溯。

六、可靠性与使用注意事项

  • 温度特性:X7R 在低温或高温条件下会有最多 ±15% 的容量变化,设计时应预留裕量以满足功能要求。
  • 偏压与温度耦合作用:较高的直流偏压和环境温度可能引起电容容量下降(DC bias effect),在关键电源去耦或滤波处需验证实际工作容量。
  • 焊接工艺:推荐采用标准回流焊曲线,避免急速升温或超出温度峰值时间,防止裂纹与性能退化。回流后建议做外观与电气抽样检验。
  • 机械应力:贴片电容对 PCB 弯曲敏感,贴装与夹具设计应尽量减少板弯曲与应力集中,必要时采用边缘增强或孔位分布优化。

七、选型建议

  • 若需更高稳定性与更小温漂,可考虑 C0G/NP0 系列(但容量通常受限);若需要更高电压或更大容量,选择更大封装或多层并联方案。
  • 在高精度滤波或计时电路中,评估 X7R 的温漂与偏压效应是否满足要求;在电源去耦场合,单片 1µF X7R 常能提供良好效果,亦可与 0.1µF 陶瓷并联以提升高频响应。
  • 注意与 PCB 材料、工作温度范围和长期可靠性需求匹配,必要时与供应商确认加速寿命试验与相关可靠性数据。

总结:CGA0805X7R105K250MT(HRE/芯声)以 0805 小体积、1µF 容量与 X7R 温度特性,提供了一种在功率去耦、滤波与一般旁路应用中兼顾容量与稳定性的实用选择。通过合理的板级布局与焊接工艺,可在多类电子产品设计中实现可靠应用。

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
