LFB152G45CB2D320 产品概述
一、产品简介
LFB152G45CB2D320 为 muRata（村田）推出的小型陶瓷带通滤波器，针对 2.45 GHz ISM 频段优化设计。器件采用 SMD-4P 超小封装（1.0 × 0.5 mm），适合空间受限的无线模块与移动终端，用于抑制带外干扰、改善接收灵敏度并保护前端放大器。
二、主要参数
- 滤波类型：带通（Band-pass）
- 中心频率：2.45 GHz
- 绝对带宽（通带）：2.40 GHz ～ 2.50 GHz
- 系统阻抗：50 Ω
- 插入损耗：典型 1.7 dB（请参见数据表获取频率依赖曲线）
- 工作温度：-40 ℃ ～ +85 ℃
- 封装：SMD-4P，尺寸 1.0 × 0.5 mm
- 品牌：muRata（村田）
三、关键特性与优势
- 极小体积：1.0 × 0.5 mm SMD 封装，便于高密度 PCB 布局与模块化设计。
- 针对 2.45 GHz ISM 频段优化：适配蓝牙、Wi‑Fi（2.4 GHz）、ZigBee 及其他物联网无线协议的前端滤波需求。
- 低插入损耗：典型 1.7 dB，有利于维持系统链路预算与发射/接收性能。
- 宽温度范围：满足工业级环境下长期可靠工作要求。
四、典型应用场景
- 无线通信模块（Bluetooth、Wi‑Fi、ZigBee）
- IoT 终端与无线传感器节点
- 无线遥控与智能家居设备
- 前端射频滤波与带外干扰抑制
- 射频收发器与功率放大器输入/输出保护
五、PCB 布局与使用建议
- 尽量将滤波器放置于天线与射频芯片之间的靠近端，减小焊盘到器件的走线长度以降低寄生。
- 引脚周围应有连续的接地平面并采用过孔贯通（via stitching）以提高隔离与屏蔽效果。
- 保持输入/输出走线为 50 Ω 微带或带状线，以保证匹配性能。
- 遵循厂商推荐的焊盘尺寸与回流焊工艺曲线进行组装，避免超过制造商的温度极限。
- 对于功率较高的应用，参考数据表中功率处理能力与温升信息，必要时进行热管理设计。
六、可靠性与注意事项
- 器件工作温度覆盖 -40 ℃ ～ +85 ℃，适合工业与消费类应用。
- 安装与搬运时注意静电放电（ESD）防护，避免在不接地环境下直接接触引脚。
- 对于关键性能（S21、S11、相群延迟、带外衰减等），应以官方数据表与典型测试曲线为准，并在目标系统中做实际测试验证。
七、结语与资料获取
LFB152G45CB2D320 以其微型封装与针对 2.45 GHz 频段的低插入损耗特性，适合对尺寸、性能有较高要求的无线产品。更多详细电气参数、封装图与推荐焊盘信息，请参阅 muRata 官方数据手册或联系授权代理获取最新资料。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
