CGA1206X7R472K102MT 产品概述

一、产品简介

CGA1206X7R472K102MT 是 HRE(芯声)推出的一款高压多层陶瓷电容,标注容值 4.7nF(472)、公差 ±10%(K)、额定电压 1kV(102),温度特性为 X7R,封装为 1206(英制,约 3.2 × 1.6 mm)。该器件综合了较高的耐压能力与紧凑体积,适用于对空间和耐压有较高要求的电子设备。

二、主要参数

  • 容值:4.7nF(472)
  • 容值公差:±10%(K)
  • 额定电压:1000V DC(102)
  • 温度特性:X7R(-55°C ~ +125°C 范围内电容变化通常在 ±15% 以内)
  • 封装:1206 (3.2 × 1.6 mm 近似尺寸)
  • 品牌:HRE(芯声)
  • 包装形式:卷带(MT 后缀通常表示卷带包装,适合贴片机用)

三、产品特性

  • 高耐压:额定 1kV,适合直流高压或脉冲场合的滤波、耦合与旁路应用。
  • 稳定性良好:X7R 介质在宽温度范围内保持良好电容值,适合一般温度变化环境的去耦与储能应用。
  • 体积小:1206 封装在有限空间中提供相对较高的容量与耐压比,便于高密度设计。
  • SMT 兼容:支持常规回流焊工艺与自动贴装生产线,适合批量生产。

四、典型应用场景

  • 高压电源的输入/输出滤波与旁路
  • 高压耦合/直流隔离电路(如 HV 测量、传感器接口)
  • 脉冲电路与高压采样网络
  • 工业控制、电力电子与测试测量设备中的高压去耦
  • 需要高耐压且尺寸受限的消费与医疗类电子产品(应按标准进行安全与可靠性验证)

五、设计与使用建议

  • 温度与电压影响:X7R 为类介质,电容值会随温度和直流偏压发生变化。设计时建议在目标工作电压下对电容实际值进行测量验证,必要时留有裕量或采用并联/串联方案满足电容量及耐压要求。
  • 焊接兼容:兼容标准回流焊流程。建议遵循制造商的回流焊曲线,峰值温度一般不超过 260°C,并注意回流次数与冷却速率以防裂纹。
  • PCB 设计:优化焊盘尺寸与焊膏量,避免在元件附近进行强力机械加工或频繁弯折板边。布板时考虑应力缓释,减少热应力或机械应力集中。
  • 机械应力:贴片陶瓷电容对弯曲敏感,贴装后避免强烈振动或板弯曲,必要时增加支撑或选择抗震措施。

六、可靠性与测试

此类高压多层陶瓷电容通常经过以下常规可靠性测试:耐压/击穿测试、温度循环、潮湿负载、焊接热冲击、机械振动/冲击测试等。实际使用前建议索取并参考 HRE 的完整产品数据表与可靠性测试报告,以满足特定行业标准(如医疗、工业级)要求。

七、选型与注意事项

  • 若电容值随直流偏压变化影响系统性能,优先评估 C0G/NP0 或增加容量裕量的方案。
  • 在高脉冲或高频场合,考虑 ESR、介质损耗与自谐频率的影响,必要时做实际频响测试。
  • 订购时请确认完整料号(CGA1206X7R472K102MT)、包装形式与出货批次,并索取最新数据手册以获取精确的尺寸、环境与电气特性。

如需该料号的详细数据手册、封装尺寸图或耐压/电容随偏压曲线,可提供后续获取渠道或帮助联系供应商进一步确认具体性能。

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
