GRM1555C1H3R6BA01D 产品概述

GRM1555C1H3R6BA01D 为村田(muRata)生产的高稳定性多层陶瓷贴片电容器,封装为 0402(公制 1005),标称容值 3.6 pF,额定电压 50 V,温度系数 C0G(又称 NP0),面向汽车级应用并支持最高 125°C 工作环境。该器件以极低的温度漂移和低损耗特性著称,适用于对频率稳定性和容差要求很高的微小电容场合。

一、主要参数与特性

  • 标称电容:3.6 pF
  • 额定电压:50 V DC
  • 温度特性:C0G(温度系数接近 0 ppm/°C,温度稳定性优异)
  • 封装:0402(尺寸极小,适合集成密度高的电路板)
  • 工作温度:最高可达 125°C(适用于汽车级环境)
  • 低介质损耗、低电容漂移:适合高频与精密模拟电路
  • 精密度:描述中提到 0.1 pF 级精度,可用于要求严格的电容配比场合(选型时请参照厂商规格书确认容差等级)

二、典型电气性能与优点

  • 温度稳定性好:C0G 材料在 -55°C 到 +125°C 范围内保持近乎恒定的电容值,极小的温度系数保证振荡器、滤波器与定时电路的频率稳定性。
  • 低等效串联电阻(ESR)和低损耗角(tan δ):在高频工作时能保持较高的 Q 值,适合射频(RF)匹配网络和高 Q 谐振电路。
  • 直流偏置影响小:与高介电常数材料相比,C0G 的电容随直流偏置变化极小,适用于需要幅度稳定的精密测量与采样电路。
  • 汽车级可靠性:为汽车应用设计,可承受更宽的温度与可靠性要求,适用于车载电子系统(在实际项目中应参考完整可靠性试验与合规性文件)。

三、典型应用场景

  • 高频振荡器与滤波电路:用于谐振回路、LC 谐振器与带通/带阻网络的定值电容。
  • 射频阻抗匹配:在射频前端进行微调与阻抗匹配时常用的小值电容。
  • 精密模拟电路:采样保持电路、测量仪器、安定振荡器、时钟电路等对温度和电压稳定性要求高的场合。
  • 汽车电子:传感器前端、车载通信与雷达系统等对温度范围和可靠性有较高要求的场景。

四、PCB 布局与焊接建议

  • 布局:0402 封装体积小,布线应尽可能短且直接,尤其是在 RF 与高频信号路径中,减少串联电感与寄生电容对性能的影响。
  • 接地与旁路:若与地有关的布局,应确保地平面连续,避免信号回流路径变长导致干扰。
  • 焊接工艺:支持常规回流焊工艺。为保证焊接可靠性与避免热冲击,遵循制造商的回流曲线建议。0402 封装手工焊接相对困难,推荐使用机器贴装与回流。
  • 机械应力:贴片电容对印刷电路板弯曲、强力清洗或冷却/加热应力敏感,设计时应避免在焊接后产生过大机械应力。

五、选型与使用注意事项

  • 确认容差与温度系数:尽管 C0G 提供卓越的温度稳定性,但在不同容差下的精度差异会影响最终电路表现,选型时请核对规格书中容差(如 ±0.1 pF、±5% 等)信息。
  • 直流偏置与频率影响:C0G 电容直流偏置效应小,但在极高频率下仍受寄生影响,实际设计应考虑等效串联电感(ESL)与 PCB 寄生参数。
  • 环境与可靠性要求:用于汽车关键子系统时,请与供应商确认是否满足相应的汽车可靠性认证与试验(如温度循环、湿热、机械冲击等)。
  • 储存与干燥:小封装贴片器件可能受潮吸湿影响焊接质量,根据生产线要求控制储存和回流前的烘烤条件。

六、采购与包装信息

该型号为村田常见的小尺寸精密陶瓷电容,通常以卷装(reel)方式供货,便于 SMT 机器贴装。具体包装数量、包装模式与可追溯性(批次号、制造日期)请在采购时向供应商或村田官方资料确认,以满足生产与质量追溯要求。

总结:GRM1555C1H3R6BA01D 以其 3.6 pF、50 V、C0G 的组合在需要高稳定性与低损耗的小值电容应用中表现出色,特别适合高频、微波匹配以及汽车级精密电路。选型时应参考完整规格书并结合实际应用环境与可靠性要求进行验证。

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.
