GRM155R71A474KE01D 产品概述

一、产品简介

GRM155R71A474KE01D 是村田(muRata)生产的一款多层陶瓷电容(MLCC),尺寸为 0402(约 1.0 × 0.5 mm),标称电容值 470 nF,额定电压 10 V,温度特性为 X7R,初始容差 ±10%。该系列属于高容值、高密度的片式陶瓷电容,适合表面贴装工艺,常用于空间受限的移动与消费类电子、通信和电源模块中作为去耦、电源滤波与旁路元件。

二、关键参数(要点)

  • 电容:470 nF(0.47 μF)
  • 容差:±10%
  • 额定电压:10 V DC
  • 温度特性:X7R(-55 °C 至 +125 °C,温漂限值依标准)
  • 封装:0402(SMD,约 1.0 × 0.5 mm)
  • 类型:陶瓷 MLCC(多层)
  • 品牌:muRata(村田)

三、性能特点

  • 体积小、容量高:0402 封装下能提供 470 nF 容值,有利于在有限 PCB 面积上布置密集去耦阵列。
  • 稳定性适中:X7R 材料在宽温度范围内提供相对稳定的电容变化特性,适合通用电源去耦与滤波用途。
  • 低等效串联电阻(ESR)与低串联电感(ESL):在高频去耦场合表现良好,有利于抑制电源瞬态与高频噪声。
  • 适配自动化贴装:为卷带(Tape & Reel)包装,符合 SMT 生产线的效率要求。
  • 环保合规:常见为无铅 / RoHS 合规产品(以官方资料为准)。

四、典型应用场景

  • 电源去耦:稳压器、PMIC、SoC 和射频器件的局部去耦,抑制开关瞬态与高频噪声。
  • 滤波回路:作为输入/输出滤波或 RC 网络的一部分,用于音频、基带与模拟前端的滤波。
  • 信号耦合/旁路:在模拟或混合信号电路中担任短时能量存储与旁路作用。
  • 移动终端与可穿戴设备:空间受限、要求轻薄与高可靠性的便携式电子产品。

五、封装与安装建议

  • PCB 封装尺寸:建议严格按照村田官方数据手册提供的焊盘尺寸与过孔间距设计 PCB,避免过大或过小焊盘引起焊接问题或机械应力集中。
  • 回流焊工艺:遵循 JEDEC / IPC 的标准回流曲线,并参考村田的焊接建议。避免重复高温或长时间暴露在高温下以降低裂纹风险。
  • 机械应力管理:0402 等小型 MLCC 对弯曲与局部应力较敏感,布线时尽量避免在元件下方产生刚性凸起,装配后 PCB 弯曲应控制在可接受范围。
  • 清洗与超声:使用清洗工艺前请参照厂方说明,长时间或强烈超声可能导致器件损伤。

六、可靠性与测试要点

  • 温度与频率依赖:X7R 为高介电常数陶瓷体系,电容会随温度与频率变化,在低频及高温条件下变化更明显。设计时应考虑在工作点(温度、频率、直流偏置)下的实际电容值。
  • 直流偏置效应:当施加直流电压时,高介电常数陶瓷电容的有效电容会下降,需在系统设计阶段验证在额定工作电压下的实际可用电容。
  • 机械可靠性:在贴装后,建议进行热循环与振动测试以验证焊接质量与元件应力抗性,特别是在汽车或工业等高可靠性场合需更严格的认证。
  • 取样验证:对于关键应用,应基于样片做电容、损耗、振动、热冲击及寿命可靠性评估。

七、选型建议与注意事项

  • 如果要求高温稳定与极小温漂(例如精密时间常数或滤波器),可考虑 C0G/NP0 型陶瓷电容替代;若要求更大容量且对温漂允许范围较宽,X7R 是成本与体积的折衷选择。
  • 在高直流偏置或高工作电压下,请参考厂方曲线或实测数据以确认实际电容满足系数。
  • 生产选型时,参照村田最新数据手册获取完整电气特性、尺寸图和推荐焊盘,并确认包装和最低订购量(Tape & Reel)信息。
  • 对于关键安全或长寿命产品(如医疗、汽车),应联系村田或授权分销商获取完整的可靠性报告与认证支持。

如需更精确的电气特性曲线(温度/频率/偏压下的电容保持率、额定电流/耐压/回流温度极限、推荐 PCB 焊盘尺寸等),建议参考村田 GRM155R71A474KE01D 的官方数据手册或联系村田技术支持获取最新资料。

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
