村田GRM0335C1H5R1CA01D 贴片陶瓷电容(MLCC)产品概述

村田(muRata)GRM0335C1H5R1CA01D是一款面向高频、高精度场景设计的多层陶瓷贴片电容(MLCC),凭借超小0201封装、C0G(NP0)陶瓷的高稳定性,成为无线通信、射频电路等领域的关键被动元件。

一、产品基本信息

该型号属于村田高频高精度MLCC系列,型号编码对应核心特性:

  • GRM:村田MLCC通用前缀;
  • 0335:封装代码,对应英制0201(公制尺寸约0.60mm×0.30mm×0.30mm),适配高密度PCB布局;
  • C:高精度容差等级;
  • 1H:额定电压50V DC;
  • 5R1:标称容值5.1pF(“R”表示小数点);
  • CA01D:端电极与批次规格(三层Ni/Sn镀层,焊接可靠性强)。

二、核心技术参数

参数项 典型值/规格 标称容值 5.1pF 额定电压 50V DC 温度系数 C0G(NP0,≤±30ppm/℃) 容差 ±0.1pF(高精度级) 损耗角正切(tanδ) ≤0.15%(1kHz,25℃) 工作温度范围 -55℃ ~ +125℃ 封装尺寸(L×W×H) 0.60mm×0.30mm×0.30mm(典型) 端电极结构 Ni/Sn 三层镀层(兼容回流焊)

三、C0G陶瓷材料的核心优势

采用Class 1型C0G陶瓷(区别于Class 2的X7R/X5R强介电材料),核心优势在于:

  1. 温度稳定性极致:容值随温度变化的漂移量≤±30ppm/℃,即使在-55℃至+125℃宽温范围内,容值波动可忽略;
  2. 电压稳定性优异:无Class 2材料的“电压降容”效应,直流偏置下容值变化极小,适合射频电路的偏置场景;
  3. 高频损耗极低:tanδ≤0.15%,在1GHz以上高频段仍保持低信号衰减,避免能量损失;
  4. 长期可靠性高:陶瓷材料无老化效应,容值随时间变化可忽略,适合长期稳定工作的场景。

四、封装与可靠性设计

作为0201超小封装MLCC,该型号在小尺寸下仍保证高可靠性:

  • 端电极优化:采用Ni基底层+中间层+Sn镀层的三层结构,焊接时形成牢固的金属间化合物,抗热冲击能力强(回流焊260℃/10s无开裂);
  • 多层陶瓷工艺:村田专利的薄介质层工艺,在0201封装内实现5.1pF的稳定容值,无“短层”“开路”等缺陷;
  • 标准测试验证:通过AEC-Q200(汽车级)、IEC 60384-1(电子级)等标准测试,涵盖温度循环(-55℃125℃,1000次)、湿度老化(85℃/85%RH,1000h)、振动测试(102000Hz,1.5g)等,确保恶劣环境下稳定工作。

五、典型应用场景

因高精度、高稳定性、小尺寸特性,广泛应用于以下领域:

  1. 无线通信模块:蓝牙5.0、WiFi 6、LTE等射频前端的匹配网络、滤波器(如低通/带通滤波器的谐振电容);
  2. 高频振荡器:晶振、压控振荡器(VCO)的负载电容,保证输出频率稳定(如GPS模块的10MHz晶振负载);
  3. 测试测量仪器:示波器、信号发生器的高精度滤波电路(如1GHz以上信号的去耦/耦合);
  4. 高速数字电路:CPU、FPGA的高频去耦电容(补充Class 2电容的高频特性不足);
  5. 汽车电子:车载T-BOX、ADAS传感器的通信电路(符合AEC-Q200标准,抗汽车级环境冲击)。

六、选型与替换注意事项

若需替换该型号,需满足以下核心参数一致:

  1. 封装:必须为0201(GRM0335),避免因尺寸差异导致PCB焊接问题;
  2. 容值与容差:5.1pF±0.1pF(C0G级),不可用X7R/X5R等Class 2材料代替(稳定性差);
  3. 额定电压:≥50V DC(避免过压击穿);
  4. 温度系数:C0G(NP0),若替换为其他温度系数(如N750),会导致容值漂移影响电路性能。

村田同系列替代型号:GRM0335C1H5R1CA01D(同参数不同批次);跨品牌替代可参考TDK C0603C0G5R1C500(0201封装,C0G,5.1pF,50V)。

总结:GRM0335C1H5R1CA01D是村田针对高频高精度场景打造的核心MLCC,以超小封装、C0G的极致稳定性,成为无线通信、汽车电子等领域的首选被动元件之一。

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
