HCCF3-10.700-LTCVS3L 陶瓷介质滤波器产品概述

一、产品核心身份与定位

HCCF3-10.700-LTCVS3L是杭晶电子(HCI)推出的表面贴装陶瓷介质中频滤波器,聚焦10.7MHz经典中频频段,通过窄带选通特性实现信号滤波与杂波抑制,广泛适配消费电子、无线通信、广播电视等领域的小型化设备设计需求。

二、关键性能参数深度解析

该产品的核心参数直接决定应用适配性,具体解析如下:

  1. 中心频率:10.7MHz
    10.7MHz是中频滤波的成熟标准频率,广泛应用于FM收音机、对讲机等设备的中频解调环节。该频率稳定性高,与主流射频电路的中频设计兼容,无需额外频率校准。
  2. 带宽:180kHz
    属于窄带滤波范畴(中心频率的±0.84%),可有效滤除中心频率±90kHz以外的干扰信号(如邻频杂波、噪声),保证输出信号纯度,提升后续解调/放大电路的信噪比。
  3. 插入损耗:4dB
    该损耗值在SMD小封装陶瓷滤波器中表现优异:既通过窄带滤波实现有效干扰抑制,又将信号衰减控制在合理范围,避免过度增加后续电路的增益需求,平衡了滤波效果与信号完整性。

三、封装与物理特性说明

  1. 封装类型:SMD-3P(表面贴装3引脚)
    3引脚结构(通常为“输入-输出-接地”布局)适配自动化贴片生产,大幅提升电子设备生产效率,降低人工成本;引脚间距符合常规PCB设计规范,焊接可靠性高。
  2. 尺寸:7×3mm
    小型化封装节省PCB空间,适配便携式设备(如手持对讲机、迷你FM收音机)、高密度电路板设计,满足当前电子设备“轻薄化”趋势。
  3. 材质与结构
    采用陶瓷介质材料,相比传统LC滤波器,具有温度稳定性好(温度系数低)、抗振动冲击能力强、长期一致性高等优势,无需现场调整,可直接批量应用。

四、典型应用场景适配

该产品因性能与封装的匹配性,可覆盖多类场景:

  1. 消费电子领域:FM调频收音机的中频滤波环节,抑制邻频干扰,提升收音清晰度;迷你蓝牙音箱的信号预处理模块。
  2. 无线通信领域:手持对讲机、短距离无线传输设备的中频选通,保证语音/数据信号传输质量。
  3. 广播电视领域:卫星接收前端、有线电视信号放大器的中频滤波,过滤杂波信号,提升接收稳定性。
  4. 仪器仪表领域:信号发生器、频谱分析仪的中频模块,实现特定频段信号精准选通,提高测试精度。

五、品牌与可靠性保障

  1. 品牌背书:HCI(杭晶电子)是国内专注于陶瓷滤波器、谐振器的知名制造商,拥有20余年专业生产经验,产品覆盖消费级、工业级场景,符合国内外电子行业标准。
  2. 可靠性优势:
    • 陶瓷介质固有特性:工作温度范围宽(典型-40℃~+85℃),抗老化能力强,长期使用性能稳定;
    • 生产管控:采用自动化生产与严格质量检测,每批次产品一致性达标率高;
    • 环保合规:符合RoHS、REACH等指令,满足国际市场准入要求。

六、选型与应用注意事项

为保证性能充分发挥,需注意以下要点:

  1. PCB适配:确认焊盘尺寸与7×3mm封装匹配,避免焊接偏移或假焊;3引脚布局需参考HCI官方 datasheet明确输入、输出、接地连接。
  2. 阻抗匹配:通常输入输出阻抗为50Ω/75Ω,需与前后级电路(混频器、放大器)阻抗匹配,减少反射损耗。
  3. 环境适配:确认应用场景温度、湿度范围符合产品参数(-40℃~+85℃),避免极端环境影响性能。
  4. 杂波验证:应用前需确认干扰信号频率是否在180kHz带宽之外,若存在同带宽干扰,需结合多级滤波抑制。

该产品以“高性能+小封装+高可靠性”为核心优势,是10.7MHz中频滤波场景的优选方案,可满足不同行业客户的小型化、高稳定性设计需求。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
