GRM1555C1H681JA01D 产品概述
一、产品基本信息
GRM1555C1H681JA01D 为村田（muRata）生产的一款多层陶瓷贴片电容（MLCC），规格为 680 pF，容差 ±5%（J），额定电压 50 V，介质为 C0G（NP0）。封装为 0402（约 1.0 × 0.5 mm），适用于需要高稳定性、低损耗的精密模拟与高频电路。
二、电气性能要点
- 温度特性：C0G/NP0 表示近乎零温度系数，典型变化非常小（约 0 ± 若干十 ppm/°C），适合对温度敏感的电路。
- 损耗与品质因数：C0G 介质损耗极低，等效串联电阻和损耗角正切（tanδ）非常小，利于在高频下保持高 Q 值与低相位误差。
- 电压特性：额定电压 50 V；与 X7R 等高介电常数材料相比，C0G 在直流偏压下的电容变化极小。
- 工作温度范围：典型适用范围为 -55°C 至 +125°C（请按实际应用与数据表确认详细数值）。
三、典型应用场景
适用于要求稳定电容值与低损耗的场合，例如：射频匹配与滤波、振荡器与时钟电路、精准采样/ADC 前端、阻抗补偿、精密滤波和时间常数电路等。
四、封装与装配建议
- 尺寸：0402（约 1.0 × 0.5 mm），适合高密度贴装。
- 焊接：兼容常规回流焊工艺，遵循厂商回流温度曲线以保证焊接可靠性。
- PCB 布局：电容端子与信号端尽量缩短走线以减少寄生电感；在关键接地位置使用短、粗的接地回路；贴片附近避免机械应力集中，减少板弯曲导致的裂纹风险。
- 存储与处理：避免长期潮湿环境，开封后按湿敏等级及回流工艺要求处理。
五、选型与替代考量
当需要更大电容值或更小体积时，可参考同系列或其他介质（如 X7R、X5R）的产品，但需权衡温度稳定性、直流偏置与损耗。型号标识中常见的“681”代表 680 pF，“J”代表 ±5% 容差，便于快速识别。
六、优势总结
GRM1555C1H681JA01D 以其 C0G 介质带来的高温稳性、低损耗和极小的电容漂移，配合 0402 小封装，适合高密度板上的精密模拟与高频应用，是需要稳定电气特性的设计中常用且可靠的选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
