GJM1555C1H3R3BB01D 产品概述

一、产品简介

GJM1555C1H3R3BB01D 为 muRata(村田)生产的多层陶瓷贴片电容(MLCC),封装为 0402(1005 公制),标称容量 3.3 pF,额定电压 50 V,温度系数 C0G(又称 NP0),容量公差为 ±0.1 pF。该型号属于高稳定性、低损耗的 NP0/C0G 陶瓷体系,适合需严格控制容量随温度与电压漂移的高频和精密电路。

二、主要性能与特点

  • 容值、精度:3.3 pF,绝对公差 ±0.1 pF(适合对容量精度有较高要求的电路设计)。
  • 温度特性:C0G/NP0,温度系数接近零,工作温度范围内容量变化极小,适合高稳定性设计。
  • 额定电压:50 VDC,适用于中低电压的信号与射频链路。
  • 高频特性:介质损耗低、Q 值高,在射频、滤波与耦合场合表现优良;相对于高介电常数陶瓷,其直流偏压导致的容量衰减可忽略。
  • 机械与封装:0402 小尺寸,便于高密度贴片与自动化贴装,但对贴装工艺与机械应力更敏感。

三、典型应用场景

  • 射频匹配网络、天线匹配与滤波器中的调谐/耦合电容;
  • 高频振荡器、时钟、参考电路的负载/补偿电容;
  • 精密采样、ADC 输入、模拟前端中对容量漂移敏感的耦合与定时元件;
  • 高频旁路/去耦(小容值场合)及射频开关或混频器中的隔直/耦合。

四、选型与设计注意事项

  • 公差与测量:±0.1 pF 的公差要求在 PCB 布局与测试时采用合适的测量夹具及去除寄生影响的测试方法。
  • 直流偏置与温漂:C0G/NP0 对 DC 偏置与温度变化的影响非常小,适用于需高稳定性的场合。
  • 封装影响:0402 尺寸适合高密度板,但要注意焊盘设计、过孔距及回流工艺以避免应力导致裂纹。
  • 电压与能量:50 V 额定电压需满足最大工作电压及浪涌要求,如有更高压或脉冲能量需求应选更高额定电压或不同结构件。

五、安装、可靠性与检验

  • 工艺兼容性:支持主流无铅回流工艺(请按产商数据表和 J-STD-020 推荐回流曲线执行);避免过度的机械挠曲与焊接应力。
  • 可靠性:村田为业界主流厂商,生产过程与品质控制严格;若用于汽车或航空等高可靠性场合,请确认该具体料号是否通过 AEC-Q 或相关认证。
  • 抗静电与储存:作为小容值高频件,装配与测试时注意 ESD 防护与避免潮湿环境长期暴露。

六、替代与采购建议

  • 在设计替代件时,可选用其他厂商(如 TDK、KEMET、Yageo 等)同规格(0402、3.3 pF、50 V、C0G/NP0、±0.1 pF)的料号,但需验证封装尺寸、电气特性及温漂一致性。
  • 采购时优先采用原厂或授权分销渠道,按需选择卷带(tape-and-reel)包装以利自动贴装,并索取最新数据表以确认回流参数与额外的可靠性信息。

如需,我可以基于您的具体电路(频率、工作电压、温度范围、空间限制)给出更加针对性的选型与布局建议。

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
