LFCN-400+ 产品概述
一、产品简介
LFCN-400+ 是 Mini-Circuits 推出的表面贴装低通滤波器（Signal conditioning LOW PASS FLTR / SURF MT / RoHS），采用 SMD-4P 封装，外形尺寸仅 3.2 × 1.6 mm。器件专为射频/微波前端的带外噪声抑制和信号整形而设计，便于在空间受限的现代通信、测试和仪表应用中直接贴装使用。
二、主要参数
- 滤波器类型：低通（Low Pass）
- 截止频率：560 MHz
- 系统阻抗：50 Ω
- 插入损耗：约 1 dB（通带典型值）
- 工作温度：-55 ℃ ～ +100 ℃
- 封装：SMD-4P，3.2 × 1.6 mm
- 环保：RoHS 合规
- 品牌：Mini-Circuits
三、性能与特点
- 紧凑尺寸：3.2 × 1.6 mm 的 SMD-4P 封装，适合高密度 PCB 布局。
- 低插损：通带内插入损耗约 1 dB，能在降低带外干扰的同时保持较好信号强度。
- 匹配良好：标准 50 Ω 设计，便于与射频链路中的放大器、混频器、耦合器等器件直接接口。
- 宽温度范围：-55 ℃ 至 +100 ℃，适应工业级和军规级工作环境。
- 可回流焊兼容：适用于常见的 PCB 装配流程，提高生产效率。
四、典型应用
- 无线通信发射/接收前端的带外滤除与旁带抑制
- 射频测试与测量设备的信号整形
- 卫星地面终端、雷达和导航设备的前端滤波
- 高速数据链路的干扰隔离与滤波处理
- 任何需要 50 Ω 系统阻抗且受限于空间的射频模块设计
五、封装与安装建议
为保证滤波器性能，建议在 PCB 布局时：
- 将滤波器尽量靠近信号源或敏感器件，减少走线长度与寄生电感。
- 在输入/输出端保持良好接地，使用环绕地铜或多层地平面以降低共模干扰。
- 避免在滤波器两端放置大体积金属或散热结构，防止影响频率响应。
推荐参考 Mini-Circuits 的封装与布局手册以获得最佳性能。
六、可靠性与环境适应性
LFCN-400+ 设计满足苛刻环境要求，-55 ℃ 至 +100 ℃ 的工作温度保证其在高温环境和低温条件下稳定工作。RoHS 合规确保器件无有害物质，适用于大多数商业与工业应用。建议在极端振动或冲击环境下进行系统级验证。
七、选型与采购建议
在选型时请确认系统所需的截止频率与插入损耗指标与本器件匹配；若需要更高截止频率或不同斜率的滤波器，可咨询 Mini-Circuits 或参考其同类产品系列以比较相应的频响曲线与功率承受能力。订购时请注明型号 LFCN-400+ 及封装要求，确保与 PCB 装配工艺一致。

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.
