CGA0402X7R682K500GT 产品概述

一、产品简介

CGA0402X7R682K500GT 是 HRE(芯声)推出的一款高密度多层陶瓷电容,标称容量 6.8 nF(682),容差 ±10%(K),额定电压 50 V(500),介质材料为 X7R,封装为 0402(约 1.0 × 0.5 mm)。该型号定位为通用型 SMD MLCC,兼具小封装、高频特性与稳定性,适合在空间受限的消费电子、通信、工业控制等电路中作耦合、滤波与去耦使用。

二、材料与电性能要点

  • 介质:X7R,温度范围典型为 -55°C 至 +125°C,介电常数随温度变化可在 ±15% 范围内(X7R 级别特性);同时 X7R 在体积/容量比上优于 C0G/NP0,适用于中等精度要求的场合。
  • 容值与精度:6.8 nF,±10%,满足多数滤波、去耦与旁路应用的容量稳定性要求。
  • 额定电压与偏置效应:50 V 额定电压,但需注意 MLCC 在直流偏置下容量会下降(小尺寸高电压器件尤甚),在高工作电压条件下建议做实际测试或留裕量。
  • 高频性能:0402 小封装寄生电感低,适合高频去耦与射频链路的旁路滤波,但若追求极低损耗应评估具体 DF/ESR 指标。

三、典型应用场景

  • 电源去耦与旁路(与大容量电容并联以覆盖宽频带);
  • 高频滤波、阻抗匹配与信号链耦合/隔直;
  • 微控制器、电源管理芯片、射频模块和移动设备等对板面密度要求高的电子产品;
  • 汽车电子、工业控制等需在较宽温度范围内稳定工作的场合(在满足环境与寿命测试前提下)。

四、封装与焊接注意事项

  • 封装 0402 适合高密度贴装,但焊盘尺寸与回流曲线需按厂方推荐值设计,避免过热或焊点不良;
  • 建议使用标准回流焊工艺进行贴装,遵循焊膏量、焊盘形状与PCB热扩散匹配原则;
  • 存储与防潮处理建议按常规 SMD 元件标准(吸湿敏感度按供货包装与厂方说明执行),开盘后在规定时间内回流。

五、选型与 PCB 布局建议

  • 去耦电容应靠近电源引脚短焊点布置,走线尽量短且宽,减少寄生电感与串联阻抗;
  • 对于电源纹波与瞬态响应要求高的电路,建议把 0402 与更大容量、低 ESR 电容并联使用;
  • 在高压或高温工作条件下,评估直流偏置与温漂后的实际有效容量,必要时选择更大额定容量或并联增加裕量。

六、型号说明与包装

  • 型号解析示例:CGA0402X7R682K500GT — 表示 0402 封装、X7R 介质、6.8 nF、±10%、50 V。GT 常用于表征端子电镀或出厂包装形式,具体以 HRE 出货资料为准。

总结:CGA0402X7R682K500GT 以其小体积、高封装密度与良好频率特性,适合多种去耦和滤波场合;在选型与设计时需注意 X7R 的温漂与直流偏置效应,并按 PCB 与焊接规范进行布局与装配,以保证在目标应用中的可靠性与性能。若需更详细的电气参数(如温度/偏置曲线、耐压试验、焊接规范或样品数据),建议向 HRE(芯声)索取完整规格书(Datasheet)。

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
