GRM0335C1H2R4CA01D 产品概述

一、主要参数

  • 品牌:muRata(村田)
  • 型号:GRM0335C1H2R4CA01D
  • 类型:贴片多层陶瓷电容(MLCC)
  • 容值:2.4 pF
  • 额定电压:50 V DC
  • 温度系数:C0G(又称 NP0,典型温度特性为 0 ±30 ppm/°C)
  • 封装:0201(超小型贴片,适合高密度布板)

二、产品特点与电气性能

GRM0335C1H2R4CA01D 采用 C0G(NP0)低损耗陶瓷介质,具有极好的温度稳定性和线性电容特性。C0G 材料在宽温度范围内保持接近恒定的电容值,温漂很小,失真系数和介质损耗非常低,适合对相位、频率稳定性要求高的电路。与高介电常数材料相比,C0G 在直流偏置下的容量衰减很小,因此在高精度射频、计时和滤波应用中表现优异。

主要电气优势:

  • 温度稳定性好(0 ±30 ppm/°C),在 -55°C 到 +125°C 范围内性能稳定。
  • 低介质损耗(高 Q 值),适合射频和高频应用。
  • 低寄生电感和电阻,适用于高频并联和旁路用途。
  • 小容值且公差范围适合高精度要求的定时和谐振电路。

三、典型应用场景

  • 射频电路中的耦合、匹配和谐振电容(如 VCO、滤波器、LNA)。
  • 时钟、振荡和谐振网络(石英振荡器负载、RC 精密基准)。
  • 高速数字电路中的去耦与阻抗整形(要求低寄生和稳定容值时)。
  • 精密模拟电路(ADC、DAC 的采样和滤波电路)。
  • 小型化电子设备与可穿戴、移动终端等对空间与性能双重要求的产品。

四、封装与装配注意事项

0201 封装尺寸非常小,带来高密度贴装优势的同时,对 PCB 设计和装配工艺提出更高要求:

  • 推荐使用适配 0201 的贴片炉回流温度曲线及精确的贴装位置控制。
  • 在焊盘设计上应参考村田的推荐 land pattern,避免过大或过小焊盘导致焊点可靠性问题。
  • 由于体积小,在振动、冲击条件下应注意机械应力隔离,可增加阻尼结构或避免位于焊缝高应力区。
  • 保持良好的防潮措施,建议按厂家包装和储存规范进行干燥箱管理,防止吸湿后回流时发生焊接缺陷。
  • 操作和测试时避免直接用尖端工具接触元件端面,防止物理损伤或裂纹。

五、选型建议与替代考虑

  • 如果电路对温漂、频率稳定性和低损耗有严格要求,C0G 是优先选择。
  • 若需要更大电容值或更高额定电压,可考虑封装稍大尺寸或采用不同介质的型号,但需权衡温漂和直流偏置影响。
  • 在对成本或体积有进一步约束时,可咨询供应商同系列不同容量的 0201/0402 封装以匹配生产与性能需求。
  • 对有关长期可靠性、焊接工艺窗口或环境认证(如汽车级)有特殊要求时,建议直接参考村田数据手册或与销售工程师确认具体型号版本与认证状态。

六、总结

GRM0335C1H2R4CA01D 是一款面向高频、精密和小型化应用的 2.4 pF / 50 V / C0G MLCC,具有优良的温度稳定性和低损耗特性,适用于射频、振荡和精密模拟电路。由于 0201 的微小封装,设计时需注意焊接与机械应力管理。最终选型请结合实际工作频率、环境与可靠性要求,并参考村田官方规格书与 PCB 布局建议。若需进一步的数据(S-parameters、等效串联电阻/电感、封装尺寸图)可提供,我可帮助查询或解析厂商资料。

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
