CSA0402X7R102K500GT 产品概述

一、概述与主要参数

CSA0402X7R102K500GT 是 HRE(芯声) 系列的一款贴片多层陶瓷电容(MLCC),典型用于高密度表贴电路板。主要电气参数如下:

  • 标称电容:1 nF (102)
  • 精度:±10% (K)
  • 额定电压:50 V DC
  • 介质类型:X7R(温度系数 Class II)
  • 封装:0402(约 1.0 mm × 0.5 mm)
  • 温度范围:-55 °C 至 +125 °C(X7R 在此温区内电容变化在±15% 以内)
  • 符合环保要求:无铅 / RoHS 合规(常规出厂包装为卷带供料,适用于自动贴装)

该型号为通用型中高电压、小封装电容,适合需要在较小封装下实现 50V 隔离或旁路的场合。

二、材料特性与电性能说明

  • X7R 介质说明:X7R 属于 Class II 陶瓷介质,具有中等介电常数和较好的温度稳定性(-55 °C 至 +125 °C 范围内电容变化通常在 ±15% 以内),适用于旁路、去耦以及滤波等非精密时间基准场合。
  • 电压依赖性(直流偏置效应):X7R 系列在施加 DC 电压时会产生一定的电容下降,尤其在高电压接近额定值时更明显。设计时应关注工作电压下的实际有效电容,并在对容值敏感的电路中采用适当裕量或选择更稳定的介质。
  • ESR/ESL 特性:0402 封装体积小,ESR 和 ESL 较低,适合高频旁路和去耦;但在超高频或对损耗极其敏感的场合需参照厂商具体曲线。

三、典型应用场景

  • 电源去耦与旁路:用于 MCU、模拟电路及电源模块的局部去耦、滤波。
  • 信号耦合与滤波:音频/射频前端的耦合或滤波网络(对容差和温漂要求不是极高时)。
  • 滤波器与阻尼电路:与电阻、电感配合形成小型滤波网络。
  • 消费电子、物联网、便携设备、工业控制等需要高密度 PCB 布局的产品。

注意:若为高精度定时、频率标准或关键模拟前端,建议评估 X7R 的温漂、老化与电压依赖性对性能的影响,必要时选择 C0G/NP0 等 Class I 陶瓷或有源元件。

四、封装与组装注意事项

  • 0402 小体积适合高密度贴片,但对贴装、回流和维修都有较高要求。取料、贴装时注意防止过压、过热及机械应力。
  • 推荐采用厂商提供的 PCB 推荐焊盘与过孔设计,以降低应力集中、避免焊盘过小导致焊接缺陷或 tombstoning。
  • 回流焊工艺:遵循 J-STD-020 或相应行业规范,峰值温度及时间应参照焊膏与器件的承受能力,一般不超过 260 °C 的峰值温度并控制在规定时间内。
  • 储存与干燥:长时间未用产品应按干燥包装规范保存,防止潮湿影响贴装质量。开封后若存在吸湿风险,按厂商建议进行回流前烘烤处理。

五、可靠性与选型建议

  • 温度与电压裕量:X7R 在极端温度或高偏置电压下电容会变化,设计时建议在对性能敏感处留有裕量;若需要长期稳定的小电容,优先考虑 C0G/NP0。
  • 老化与漂移:陶瓷介质具有一定老化效应(随时间逐步减小),并且在反复热循环与机械应力下需关注可靠性测试结果。关键应用请向 HRE 获取相应环境与寿命测试数据。
  • 规范与认证:在汽车或航天等高可靠性行业使用前,请确认该型号是否通过 AEC-Q200 或其它行业认证,或与供应商沟通定制测试报告。

六、包装与采购建议

  • 常规包装为卷带(tape-and-reel),方便 SMT 贴装;可按需订购整卷或小卷,采购时咨询最小包装数量与交期。
  • 采购时建议向供应商索取样片与器件规格书(Datasheet)、回流曲线、DC bias 曲线与典型性能曲线,以便在实际电路中进行仿真验证。

总结:CSA0402X7R102K500GT 提供了在 0402 超小尺寸下的 1 nF/50 V 解决方案,兼顾空间效率与电压承受力,适合大多数消费电子及工业类电路的去耦与滤波应用。选型时重点考虑 X7R 的电压依赖性与温漂特性,并按实际工作条件核实有效电容与可靠性要求。

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.
