GRM0335C1HR90BA01D 产品概述
一、产品基本参数
- 类型：陶瓷多层贴片电容（MLCC）
- 品牌：muRata（村田）
- 型号：GRM0335C1HR90BA01D
- 容值：0.9 pF
- 公差：±0.1 pF（绝对值）
- 额定电压：50 V DC
- 温度特性：C0G（NP0），近乎零温度系数
- 封装：0201（约 0.6 mm × 0.3 mm）
- 安装方式：SMD，带盘装（Tape & Reel）
二、主要特性
- 极佳的温度稳定性与频率稳定性：C0G/NP0 陶瓷介质在宽温区间内容值基本不变，适合高精度电路。
- 低损耗、低介质吸收：适合射频及高速信号链路中对相位和增益要求严格的场合。
- 体积小、寄生量低：0201 尺寸降低串联电感和走线长度，有利于高频性能。
- 公差窄（±0.1 pF）：适用精密匹配、滤波与时基电路。
三、典型应用
- 高频匹配网络与阻抗调整（RF 前端、滤波器、天线调谐）
- 高频耦合/旁路与采样电路（ADC 前端、低噪放大器）
- 高频振荡器与定时电路（LC 谐振回路的精确电容）
- 精密仪表与测量设备中要求温漂和稳定性的元件
四、设计与使用建议
- 布局：尽量将电容放置在信号或电源点邻近位置，走线短且粗，减小串联电感与寄生电阻。关键射频点建议接地面连续、避免穿孔造成寄生。
- 焊接：符合无铅回流工艺，具体回流曲线与可允许温度请参考村田官方焊接指南以防裂纹或性能下降。
- 焊膏与印刷：0201 对焊膏量与焊盘尺寸敏感，须做工艺验证以避免 tombstoning 或焊接缺陷。
- 机加工与装配：避免在贴片后板材弯曲或机械冲击，微型封装对压力与冲击敏感，推荐在组装工艺中控制挤压应力。
- 电压降额与偏压：C0G 本身 DC 偏压影响极小，但 0.9 pF 量级在电路中会受寄生与测试条件影响，建议在目标频率与工作电压下进行实测确认。
五、可靠性与品质保证
- 村田为全球知名被动元件制造商，产品通过常规电气与环境测试（如温度循环、湿热、机械冲击等）。
- 常见失效模式为机械损伤（裂纹、断裂）与不良焊接（虚焊、桥联），建议在 PCB 设计和装配流程中加强控制。
- 环保合规：符合 RoHS 等环保要求（具体合规证明请参阅厂家文件）。
六、采购与替代建议
- 订购时请使用完整型号 GRM0335C1HR90BA01D，并确认包装形式（卷带/盘装）与最小包装量。
- 若需不同公差或电压等级，可咨询村田同系列 C0G 0201 尺寸的其他型号；在无特殊频率要求下也可考虑等效 NP0 产品替代，但关键射频或精密应用应先做电性验证。
总结：GRM0335C1HR90BA01D 以其 0.9 pF、C0G 温漂、0201 小封装与窄公差的组合，适合对稳定性、频率特性与体积有严格要求的高频与精密电子设计。选型与上板时请注意焊接工艺与机械应力控制，必要时参考厂方技术资料以确保长期可靠性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
