村田GRM1555C1H122JA01D 多层陶瓷贴片电容(MLCC)产品概述

一、产品型号与基础定位解析

GRM1555C1H122JA01D是村田(muRata)推出的高频精密多层陶瓷贴片电容(MLCC),属于其经典GRM系列通用型产品,针对温度稳定性、容值精度要求苛刻的高频/精密电路设计。型号各部分核心含义如下:

  • GRM:村田MLCC产品系列代号(Generic Multilayer Ceramic Capacitor);
  • 1555:封装尺寸代码,对应英制0402(公制1.0mm×0.5mm);
  • C:温度系数代码,代表Class 1陶瓷材料C0G(对应EIA标准NP0);
  • 1H:额定电压代码,对应直流额定电压50V;
  • 122:容值代码,按“前两位有效数+第三位10的幂次”计算,即12×10²pF=1200pF=1.2nF;
  • J:容值精度代码,代表±5%;
  • A01D:制造规格与批次细节(村田内部编码,无参数调整)。

二、核心电气性能参数

该产品关键指标符合村田内部及IEC 60384-1国际标准,具体如下:

参数项 规格值 测试条件 标称容值(C) 1.2nF(1200pF) 1kHz/1Vrms 容值精度(Tolerance) ±5%(J级) 25℃ 额定电压(VR) 50V DC 工作温度范围内 温度系数(TCC) ≤±30ppm/℃(C0G) -55℃~125℃/1kHz 损耗角正切(tanδ) ≤0.15% 25℃/1kHz 绝缘电阻(IR) ≥10^10 Ω 25℃/50V DC(1分钟) 自谐振频率(SRF) ≈100MHz(典型值) 无负载条件

注:以上为典型值,具体以村田官方最新 datasheet 为准。

三、封装与物理特性

采用0402小型化封装,适配高密度贴装需求:

  • 封装尺寸:英制0402(0.04″×0.02″),公制1.0mm(长)×0.5mm(宽);
  • 厚度:典型值0.5mm(含端电极);
  • 端电极结构:Ni(镍)底层+Sn(锡)表层镀层,符合RoHS 2.0及REACH法规,无铅环保;
  • 重量:约2mg(0.002g),轻量化不增加电路负荷;
  • 焊接兼容性:支持260℃回流焊(符合JEDEC J-STD-020),适配无铅焊接流程。

四、材料体系与温度稳定性优势

基于Class 1钛酸锶基陶瓷材料(C0G系列),与Class 2陶瓷(如X7R)相比,具备三大核心优势:

  1. 容值漂移极小:-55℃~125℃宽温范围内,容值变化≤±0.3%(按30ppm/℃计算,180℃温差漂移仅0.54%,实际工艺可优化);
  2. 无直流偏置效应:Class 1陶瓷无电容-电压(C-V)特性变化,额定电压下容值无明显下降;
  3. 低损耗特性:tanδ≤0.15%,高频电路中减少信号损耗,提升效率。

五、典型应用场景

因“高精度、高稳定、低损耗”特性,广泛应用于:

  1. 高频通信:蓝牙/WiFi模块射频匹配网络、2.4GHz/5GHz滤波器、天线调谐电路;
  2. 精密模拟:运放反馈电容、ADC/DAC参考滤波、传感器信号调理;
  3. 工业控制:PLC模拟I/O滤波、电机驱动高频噪声抑制;
  4. 消费电子:智能手机WiFi前端、蓝牙耳机射频电路、智能手表传感器滤波;
  5. 医疗电子:低噪声放大器(LNA)匹配电容、监护设备信号滤波(需符合安规)。

六、可靠性与质量保障

村田对该产品可靠性严格把控:

  1. 环境测试:通过-55℃~125℃温度循环(1000次)、85℃/85%RH湿度负荷(1000小时)、260℃焊接冲击(3次);
  2. 安规认证:符合IEC 60384-1、UL 1414等国际标准;
  3. 一致性管控:先进叠层工艺确保每批次参数一致,降低设计风险;
  4. 供应链支持:全球供应链稳定供货,适配量产需求。

七、选型注意事项

  1. 电压匹配:电路工作电压不超过50V DC,避免过压损坏;
  2. 温度范围:适用-55℃~125℃,特殊温区需选村田特殊系列;
  3. 精度升级:若需±1%精度,可选择GRM系列中J级以上产品;
  4. 焊接工艺:无铅回流焊需遵循村田推荐温度曲线。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
