LFCN-120+ 产品概述
一、产品简介
LFCN-120+ 是 Mini‑Circuits 提供的一款表面贴装低通滤波器，专为 50Ω 射频系统的信号调节与镜像/谐波抑制设计。该器件截止频率约为 195 MHz，典型插入损耗约为 1 dB，适合在射频前端、宽带接收、基带滤波及一般信号整形场合中使用。封装为常见的 1206（3216 公制），符合 RoHS 要求，工作温度范围 -55℃ 到 +100℃，可靠性满足工业级应用需求。
二、主要技术参数
- 滤波器类型：低通（Low‑pass）
- 截止频率：195 MHz（典型）
- 系统阻抗：50 Ω
- 插入损耗：典型 1 dB
- 封装：1206（3216 metric），表面贴装（SURF MT）
- 工作温度：-55℃ ~ +100℃
- 符合性：RoHS，品牌 Mini‑Circuits
三、特点与优势
- 低插入损耗：约 1 dB，降低信号衰减，保持信噪比。
- 紧凑封装：1206 尺寸便于高密度 PCB 布局与自动化贴装。
- 宽温区稳定性：-55℃~+100℃，适应工业与车规附近环境。
- 50Ω 设计：与标准射频链路直接匹配，无需额外匹配网络，简化系统设计。
- RoHS 合规：满足环保与制造要求。
四、典型应用场景
- 射频前端的低频段通带滤波与谐波抑制。
- 模数转换器（ADC）前的抗混叠/基带滤波（配合系统带宽使用）。
- 无线基站、测试测量仪器、视频/广播传输链路的信号整形。
- 通用信号调节与干扰抑制场合。
五、封装与安装建议
- 建议将滤波器放置于信号源与敏感节点（如接收器输入、ADC）之间，尽量靠近被保护器件，以抑制来自源端的高频成分。
- 在 50Ω 微带或同轴布局中保持传输线阻抗一致，走线尽量短且直。
- 提供良好接地面，避免底层开孔或地面不连续导致性能退化。
- 采用标准 SMT 回流焊工艺进行组装，遵循元件厂商的焊接与存储建议以保证可靠性。
六、环境与可靠性
LFCN-120+ 的工作温度范围和封装形式使其适用于室温、恶劣环境及长期稳定运行。对振动、热循环等工业级考量有较好的适应性，适合量产及现场部署应用。
七、使用注意与推荐
- 在系统级设计时，结合滤波器的截止频率与器件插入损耗，评估对带内群延迟和相位特性的影响。
- 对于严格的带宽或相位要求，可通过仿真与实际测试验证滤波器在目标电路中的综合表现。
- 如需更高功率处理、更多带外抑制或不同截止频率，可咨询 Mini‑Circuits 的系列产品以选型。
总结：LFCN-120+ 提供了在 195 MHz 截止附近表现优良的低通滤波功能，以 50Ω 兼容性、低插损与工业级温度范围为特色，适合多种射频与信号调节应用，且便于 SMT 工艺集成。

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.
