村田GJM1555C1HR70WB01D 0402封装MLCC产品概述

村田(muRata)GJM1555C1HR70WB01D是一款0402英制封装(公制1005)的多层陶瓷电容(MLCC),采用C0G(NP0)温度稳定型陶瓷介质,额定电压50V,容值0.7pF,专为高频、高稳定性需求的电子电路设计,广泛应用于无线通信、物联网等便携设备领域。

一、产品基本信息

GJM1555C1HR70WB01D属于村田GJM系列MLCC,型号命名对应核心参数:

  • GJM1555:0402英制封装(公制1005),尺寸为1.0±0.2mm(长)×0.5±0.2mm(宽)×0.5±0.1mm(厚);
  • C:C0G(NP0)温度系数;
  • 1HR70:容值0.7pF(村田容值代码规则:1H=0.7pF,R70为容值细分);
  • WB01D:容值公差±0.1pF,常规可靠性等级,符合工业级应用标准。

二、核心性能参数

该产品关键性能匹配高频电路对稳定性、低损耗的要求:

  1. 容值与公差:标称0.7pF,公差±0.1pF,满足精密电路对容值一致性的需求;
  2. 温度稳定性:C0G介质容值漂移≤±30ppm/℃,-55℃~+125℃全温区无明显波动;
  3. 耐压特性:50V直流额定电压,短时间可承受1.5倍额定电压(75V)过压测试;
  4. 损耗特性:1kHz下损耗角正切(tanδ)≤0.15%,2.4GHz高频下损耗仅为X7R介质的1/10以下;
  5. 工作范围:温度-55℃+125℃,频率适用范围覆盖1kHz10GHz。

三、封装与可靠性设计

GJM1555C1HR70WB01D的封装与可靠性具备以下优势:

  • 小型化适配:1.0mm×0.5mm紧凑尺寸,可节省PCB布局空间,适配智能穿戴、物联网传感器等微型设备;
  • 可靠性测试:通过JIS C 5102、IEC 60384-1等国际标准,涵盖:
    • 温度循环(-55℃~+125℃,1000次循环);
    • 湿度加载(85℃/85%RH,1000小时);
    • 振动测试(10~2000Hz,加速度2g);
  • 抗应力能力:多层陶瓷结构优化,可承受PCB弯曲(曲率半径≥25mm),减少焊接或使用中的失效风险。

四、典型应用场景

该产品因高稳定性、低损耗特性,适用于以下高频/精密电路:

  1. 无线通信:蓝牙5.0/5.1模块、WiFi 6/6E射频前端、LoRa网关的滤波器、耦合器;
  2. 物联网传感器:智能电表、环境监测节点的信号调理电路,确保数据传输稳定;
  3. 消费电子:智能手机天线匹配网络、智能手表射频模块,适配便携设备小型化需求;
  4. 工业电子:PLC高频控制电路、工业传感器信号滤波,耐受宽温环境;
  5. 医疗电子:小型监护仪信号处理电路,满足医疗设备对稳定性的要求。

五、产品应用优势

相比同容值X7R介质MLCC,核心优势显著:

  1. 温度稳定性:无容值漂移,避免射频信号频率偏移;
  2. 低损耗:高频下信号衰减小,提升传输效率;
  3. 一致性好:批次间容值偏差≤±0.1pF,减少电路调试难度;
  4. 高耐压:50V覆盖中等功率需求,无需并联低耐压电容;
  5. 环保合规:符合RoHS、REACH指令,无铅焊接兼容。

六、选型与使用注意事项

为确保性能稳定,需注意:

  1. 电压限制:电路工作电压(含纹波峰值)≤50V直流;
  2. 温度范围:使用环境需在-55℃~+125℃内;
  3. 焊接工艺:无铅回流焊推荐温度曲线(峰值230℃~245℃,时间≤30秒);
  4. PCB布局:焊盘尺寸推荐0.6mm×0.3mm,避免虚焊短路;
  5. 容值匹配:需更高容值可参考同系列GJM1555C1HR71WB01D(0.71pF)。

GJM1555C1HR70WB01D凭借C0G介质的优异性能与小型化封装,成为无线通信、物联网领域的主流选型,可满足不同场景对高稳定性、低损耗的需求。

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
