HFCN-740+ 是 Mini-Circuits 推出的一款表面贴装陶瓷滤波器,设计阻抗为 50Ω,中心频率为 1.79 GHz。器件采用 SMD-4P 封装,外形尺寸 3.2 × 1.6 mm,适合紧凑型射频前端与中频链路的带通/预选滤波要求。该器件基于陶瓷谐振技术,兼顾体积、稳定性与成本,便于大批量生产与自动贴装。
(注:具体插损、带宽、截止衰减等电参数请以厂商 datasheet 为准,设计前建议参考完整 S 参数。)
HFCN-740+ 采用陶瓷材料与金属化引脚,适合工业级环境下的长期使用。封装尺寸 3.2 × 1.6 mm 适配常见贴片生产线。器件符合无铅/RoHS 要求(具体合规信息请参照厂方资料)。为避免机械应力导致陶瓷裂纹,贴片后搬运和测试需注意避免强冲击或弯曲 PCB。
在量产前建议获取 Mini-Circuits 官方 datasheet 与 S 参数文件(Touchstone),并申请样品进行系统级评估。若系统对插损、带外抑制或功率处理有严格要求,请与厂方确认额定功率、最大输入电平与温度范围。结合目标应用选择合适的滤波器型号或考虑与厂商协商定制参数。
如需进一步的电路匹配建议、PCB 参考布局或基于 HFCN-740+ 的滤波方案仿真支持,我可以协助提供针对性的设计指导。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
