CGA1206X7R105K500NT 产品概述

一、产品基本信息

  • 类型:贴片多层陶瓷电容(MLCC)
  • 容值:1 µF
  • 精度:±10%
  • 额定电压:50 V DC
  • 材料/温度特性:X7R(-55°C ~ +125°C,典型温度系数±15%)
  • 封装:1206(英制,约3216公制)
  • 品牌:HRE(芯声)

二、主要特性

  • 高体积效率:1206封装在较小占位下可提供1 µF容量,适合空间受限的电路板布局。
  • 温度稳定性:X7R属Class II陶瓷,温度范围广但容值会在温度极限内有最多±15%的变化,适合去耦与旁路应用。
  • 低等效串联电阻/电感(ESR/ESL):适用于快速瞬态响应要求的电源滤波和稳压器输入输出旁路。
  • 耐压与可靠性:额定50 V,适合中低压电源系统;需注意直流偏压下电容值衰减现象(Bias effect)。

三、典型应用

  • 开关稳压器输入/输出去耦与滤波
  • 模拟电路与ADC/DAC缓冲旁路
  • 电源总线滤波、瞬态抑制与储能
  • 工业、消费类电子与通信设备中的常规旁路件

四、设计与布局建议

  • 靠近被去耦器件放置,走线最短,减小寄生阻抗。
  • 对于高频旁路建议并联小容量低ESL电容以改善高频性能。
  • 考虑直流偏压(DC bias)导致的有效容量下降,关键电路建议留有裕量或实际测量在工作电压下的容量。
  • 焊接与回流遵循J-STD-020等标准,避免超出元件推荐的回流峰值温度(常见上限260°C)。

五、可靠性与工艺注意事项

  • X7R陶瓷存在老化效应,容量随时间按对数规律缓慢下降,首次烧结后变化需在长期可靠性评估中考虑。
  • 卷盘/带装适配自动贴片,贴片前注意防潮处理和必要的烘烤(按供应商建议)。
  • 裸片装配时避免机械过压或焊膏过量导致的应力裂纹;焊盘设计与焊膏印刷需控制良好。

六、采购与替代建议

  • 订购时确认包装形式(卷带、盘装)、批次和放电测试记录。
  • 若项目对温漂、稳定性或偏压敏感,可考虑改用NP0/C0G(更小容量下)或更高可靠性的薄膜/钽电容作为替代方案;在同类X7R MLCC中选择更高额定电压或并联方式以降低偏压影响。

本产品适合大多数中低压电源滤波与去耦场景,选型时重点注意直流偏压与温度/时间引起的容量变化,以保证长期电气性能满足系统要求。

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
