GJM1555C1H2R7BB01D 产品概述

一、概述

GJM1555C1H2R7BB01D 是村田(muRata)推出的一款贴片多层陶瓷电容(MLCC),标称容量为 2.7 pF,额定电压 50 V,温度系数为 C0G(亦称 NP0)。封装为 0402(约 1.0 mm × 0.5 mm),面向对频率特性和温度稳定性有较高要求的高频、精密电路应用。凭借 C0G 材料体系与超小封装,该型号在射频匹配、振荡器与滤波等场景中表现优异。

二、主要性能特点

  • 极佳的温度稳定性:C0G/NP0 温度系数接近 0 ppm/°C(典型规格为 0 ±30 ppm/°C),在宽温区间内电容量基本恒定,适合高精度电路。
  • 低介质损耗:介质损耗(tan δ)极低,Q 值高,适用于射频与高频路径,能降低能量损耗与相位误差。
  • 低电压依赖性:与 X7R、X5R 等介质相比,C0G 在施加直流偏置时电容变化甚微,适合要求线性或精确容值的应用。
  • 小型化封装:0402 尺寸有助于板面节省空间,并且可实现较低的寄生电感(ESL),提升自谐振频率(SRF)。

三、电气与物理要点

  • 容值:2.7 pF;额定电压:50 V DC。
  • 温度系数:C0G(NP0),温度漂移极小。
  • 封装尺寸:0402(约 1.0 × 0.5 mm),适合表面贴装工艺。
  • 高频特性:小体积带来较低 ESL 和较高 SRF,利于射频匹配、滤波与耦合。
  • 稳定性与寿命:采用优良陶瓷基材与制造工艺,长期温湿及振动条件下表现稳定——具体可靠性指标请参照制造商数据表。

四、典型应用场景

  • 射频前端:天线匹配网络、谐振回路、带通/带阻滤波器。
  • 振荡与定时电路:高稳定性振荡器(VCO、晶体振荡器周边补偿等)。
  • 高精度模拟电路:采样、滤波与分压电路中的耦合或定值电容。
  • 高速数字与时钟系统:用于阻抗匹配和高频去耦(小容值并联用途)。

五、设计与布局建议

  • 贴片方向与布局:靠近敏感器件或放大器输入端放置,以减少引线长度和寄生电感。
  • 并联使用:在高频应用中,可与较大容值的 MLCC 并联形成跨频带的去耦/滤波网络,利用小电容的高 SRF 特性。
  • PCB 打样与焊盘:采用制造商推荐的贴片焊盘和回流工艺,保证焊点完整性与机械强度。0402 尺寸对贴装精度要求高,建议使用合适的贴片头与回流曲线。

六、焊接与可靠性提示

  • 回流焊:遵循无铅或有铅回流曲线(以厂商数据表为准),避免超温或过长高温滞留。
  • 机械应力:0402 为小型元件,避免板弯曲与过度剪切力,尤其在焊接后冷却阶段。若设备会承受频繁冲击或振动,建议评估是否需加固(如涂覆或点胶)。
  • 清洗与封装:常规焊后清洗工艺适用;包装通常为卷带卷装(Tape & Reel),便于自动贴装。

七、选型注意事项与资料获取

  • 容差与漏电流:2.7 pF 的容差与绝缘漏电流等具体参数请以村田官方数据表为准,不同后缀料号可能有不同公差或包装。
  • 工作环境:若存在极端温湿、强震或高电压脉冲,请依据应用做额外应力测试与失效分析。
  • 资料渠道:推荐参考村田 GJM 系列的产品规格书与可靠性报告,获取关于最大允许偏压、等效串联阻抗(ESR/ESL)、自谐振频率与回流焊温度曲线的详尽数据。

总结:GJM1555C1H2R7BB01D 以其 2.7 pF/50 V/C0G 的电气特性及 0402 微型化封装,适合对温度漂移、频率响应与线性有严格要求的高频与精密电子设计。选型与布局时应参考厂商数据表并结合具体应用场景进行可靠性验证。

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
