HFCN-440+ 是 Mini-Circuits 提供的一款高通射频滤波器(High‑Pass Filter),采用表面贴装(Surface Mount)封装,符合 RoHS 要求,适用于 50Ω 射频系统的信号整形与干扰抑制。该器件设计用于在低频端实现可靠的截止特性,同时在较宽频段内保持低插入损耗,适配紧凑射频前端模块和仪器设备。
说明:高通滤波器以 440 MHz 作为设计的截止拐点,在高于此频率的频段可提供预期的通带响应。插入损耗为代表性值,实际值随频率与电路环境略有变化。
HFCN-440+ 是一款体积小、适用于 50Ω 系统的高通射频滤波器,凭借 440 MHz 的截止设计、在约 500 MHz~2.5 GHz 范围内的良好通带特性以及典型 3.08 dB 的插入损耗,适合紧凑射频模块、通信前端与测试设备等多种应用场景。最终选型与应用部署应结合器件 S‑参数、功率等级和实际电路布局进行验证,确保满足系统级性能要求。

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.
