CGA0603X7R474K250JT 产品概述

一、产品简介

CGA0603X7R474K250JT 为贴片式多层陶瓷电容(MLCC),标称容量 470 nF(0.47 μF),公差 ±10%,额定直流电压 25 V,介质材料为 X7R,封装规格 0603(1.6 mm × 0.8 mm)。该型号适合高密度贴装电路板上的去耦、滤波与旁路等常规电容应用,兼顾体积与电容量之间的平衡,是消费类与工业类电子产品中常见的通用电容选择。

二、主要性能与特点

  • 容值与精度:470 nF ±10%,适用于一般去耦和旁路场合,对精密计时或高稳定性电路则建议选用 C0G/NP0 类产品。
  • 温度特性:X7R 介质可在 −55°C 到 +125°C 温度范围内工作,电容值随温度变化通常在 ±15% 范围内,适合大多数温度变化不剧烈的应用场景。
  • 电压与体积:25 V 额定电压在便携设备与低压电源中应用广泛;0603 封装提供较小的占板面积,适合高密度布板。
  • 可焊性:适配常规无铅回流焊工艺,便于 SMT 流程集成。
  • 稳定性与可靠性:MLCC 本身无极性、寿命长、无泄露电流问题,但需注意 X7R 的介电非线性和直流偏压效应。

三、应用场景

  • 电源旁路与去耦:稳定 MCU、电源芯片与射频模块电源线的瞬态响应。
  • 滤波:与电感器或其他电容构成低通/高通滤波网络,抑制电源纹波与高频干扰。
  • 耦合/旁路:信号链路的低频耦合与旁路处理(需注意 X7R 的容值漂移对精密信号路径的影响)。
  • 消费电子、通信设备、仪器仪表、工业控制等领域的通用电容需求。

四、封装与布局建议

  • 0603 尺寸约为 1.6 mm × 0.8 mm,适合高密度布线。器件高度依制造商而异,设计时应参考厂商产品尺寸表。
  • 布局建议:靠近被去耦芯片的电源引脚放置,尽量缩短回流路径;焊盘设计和焊膏量应遵循厂商或 IPC 标准,避免出现虚焊或裂纹。
  • 对于需要更大实际有效电容的场合,请评估直流偏压和温度对容量的影响,并酌情增大器件或改用更大封装。

五、使用注意事项与选型提示

  • 直流偏压效应:X7R MLCC 在较高直流电压下会出现显著电容下降,实际电容可能低于标称值,设计时应测试实际工作点的电容或预留裕量。
  • 温度与频率依赖:在高频或极端温度下,电容特性会有变化;关键参数应在目标工况下验证。
  • 若电路对容值稳定性、介电损耗(ESR/DF)或频率响应有严格要求,建议评估更合适的介质或更大封装尺寸。
  • 焊接与储存:遵循无铅回流工艺与防潮处理标准(MSL),避免在回流或存储过程中造成性能退化。

六、总结

CGA0603X7R474K250JT(470 nF,25 V,X7R,0603)是面向通用去耦与滤波应用的紧凑型 MLCC,具备体积小、易于贴装的优点。在采用时应重点考虑 X7R 的直流偏压与温度特性,必要时进行实测验证或留裕量。欲获取更详细的电气特性、尺寸图与焊接规范,请参阅厂商数据手册或联系供应商获取样品测试。

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.
