GRM1555C1H472JE01D 产品概述

一、产品简介

GRM1555C1H472JE01D 为村田(muRata)生产的一款片式多层陶瓷电容(MLCC),规格为 4.7nF(472)、公差 ±5%(J)、额定电压 50V,温度系数为 C0G(又称 NP0),封装为 0402(公制约 1005,尺寸约 1.0 mm × 0.5 mm)。该器件属于无极化、稳定型陶瓷电容,适用于对温度、频率和直流偏压敏感的精密电路。

二、主要技术参数

  • 容值:4.7 nF
  • 精度:±5%(J)
  • 额定电压:50 V DC
  • 温度系数:C0G(近似 0 ppm/°C,典型温度稳定性高)
  • 封装:0402(1005)片式
  • 特性:低介质损耗、低 ESR/ESL、频率响应好

三、特点与优势

  • 温漂极小:C0G/NP0 型材料温度特性极为稳定,适合高精度滤波、定时及振荡电路。
  • 线性好、直流偏压影响小:与 X7R、X5R 等介质相比,C0G 在直流偏压下电容量变化可忽略。
  • 高频性能优异:低 ESR 和低 ESL 特性使其在 RF、射频前端和高速数字去耦场合表现良好。
  • 小尺寸高可靠性:0402 小尺寸利于高密度 PCB 布局,同时满足自动化贴片及回流焊工艺要求。

四、典型应用场景

  • 高频滤波与阻容耦合(RF 前端、收发器)
  • 精密定时与振荡电路(晶体振荡器旁路/并联)
  • 精密模拟电路(ADC/DAC 旁路、参考电路)
  • 高速数字去耦、信号完整性优化

五、设计与使用建议

  • 温度与偏压:C0G 电容在宽温区间和高偏压下电容值稳定,但仍需遵循额定电压和工作温度范围。
  • 焊盘与布局:为避免焊接或机械应力导致裂纹,建议优化焊盘尺寸以保证良好焊点并避免过多焊料堆积;避免元件两端受力或板弯曲。
  • 去耦位置:在去耦应用中,尽量靠近电源引脚与地平面布置以减小走线电感。
  • 储存与处理:避免潮湿与碰撞,贴片后尽快回流焊;回流温度按照厂商推荐的焊接曲线执行(参考村田回流规范)。

六、可靠性与焊接注意

  • 该类 MLCC 无极性,长寿命且稳定,但对焊接应力与 PCB 机械应力敏感,推荐采取柔性线路或缓冲设计减少应力集中。
  • 回流焊:遵循厂商推荐的温度曲线,峰值温度及时间窗口应满足焊膏与元件规格。
  • 环境适应:C0G 介质在温度循环、湿热等可靠性试验中表现优秀,适合商用与工业等级应用。

七、选型要点与替代建议

  • 若需要更大容值或更小体积,可考虑不同封装或介质(但介质变更会影响温漂与偏压特性)。
  • 若成本或体积为首要考虑,可评估 X7R 等介质,但需权衡温漂和直流偏压影响。
  • 订购时注意完整料号与包装形式(如带卷盘/卷带包装),确保与 SMT 贴装工艺匹配。

总结:GRM1555C1H472JE01D 是一款在稳定性、频率响应和温漂方面表现优异的 4.7nF C0G 0402 MLCC,适合用于对精度和可靠性有较高要求的模拟、RF 及高速数字电路。在设计中注意机械应力控制与合理的 PCB 布局,可发挥其最佳性能。若需更详细的封装尺寸、回流曲线或可靠性数据,建议参考村田官方规格书或联系供应商获取原厂资料。

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
