KEMET C0402C680J5GACAUTO 产品概述
一、产品简介
KEMET C0402C680J5GACAUTO 是一款表面贴装多层陶瓷电容器（MLCC），额定容值 68 pF，公差 ±5%（J），额定电压 50 V，介质为 C0G/NP0，封装尺寸 0402（1005 公制），以自动化贴装卷带（AUTO）形式供货。C0G（NP0）介质具有优异的温度稳定性与极低的介质损耗，适合对频率和温漂有严格要求的电路。
二、主要规格与特性
- 容值：68 pF
- 精度：±5%（J）
- 额定电压：50 V DC
- 介质：C0G / NP0（温度系数接近 0 ppm/°C，工作温度范围宽）
- 封装：0402（1005 公制）
- 包装：卷带自动化包装（适于高速贴片生产）
- 主要特性：
- 极低的温度漂移与电容随温度变化小
- 极低的介质损耗，适合高 Q 应用
- 良好的电气稳定性与频率响应
三、典型应用场景
- 高稳定性振荡器与谐振电路（时钟、晶体振荡器负载）
- 射频前端匹配网络与滤波器
- 精密模拟电路（采样/保持、ADC/DAC 前端）
- 高速数字接口的旁路与互连匹配
- 电容阵列与温度敏感的参考网络
四、装配与使用建议
- 焊接：建议按 JEDEC/J-STD-020 推荐的无铅回流曲线进行回流（控制峰值温度与保温时间），避免重复高温回流。
- 焊盘与焊膏：采用厂家推荐焊盘尺寸与过孔布局，控制焊膏量以避免“浮置”或焊点不足。
- 机械应力：0402 体积小但对 PCB 弯曲、机械应力敏感，焊接时避免过度板弯或强力压装。
- 静电与清洁：器件本身非极性，但建议在装配与测试过程中采用常规静电防护与洁净操作。
五、可靠性与合规
C0G/NP0 陶瓷结构稳定、老化率低，适用于长期稳定工作的产品。KEMET 产品通常符合 RoHS 要求并通过相关可靠性测试（如温度循环、湿热、机械冲击等），具体的可靠性数据与认证请参考 KEMET 官方数据表与检验报告。
六、选型提示
- 若电路对温漂与频率稳定性要求高，C0G/NP0 是首选；若需要更大容值或更高介电常数，则需考虑 X7R、X5R 等介质，但温度稳定性与损耗会下降。
- 0402 尺寸适合高密度 PCB 布局与自动化生产；如需更高功率承受或更大容值，请选用更大封装。
- 关注实际工作电压与自我谐振频率（SRF），在高频应用中需考虑电容的寄生参数对性能的影响。
若需更详细的电气参数（如等效串联电阻 ESR、等效串联电感 ESL、温度曲线、最大偏压特性）或封装/焊盘建议图，请告知，我可提供对应的技术资料与布局建议。

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.
