FACT4532-101-2P-T — 共模滤波器产品概述
一、产品概述
FACT4532-101-2P-T 是长江微电（cjiang）推出的一款双通道共模滤波器，采用四针贴片封装（SMD-4P），外形尺寸仅 4.5 × 3.2 mm。该器件在 100 kHz 时标称共模电感 100 µH，额定电压 50 V，额定直流电流 150 mA，适用于对空间与成本有严格要求的微型电路板 EMI 抑制场景。
二、主要参数
- 通道数：2（共模，4 引脚 SMD 封装）
- 电感：100 µH @ 100 kHz
- 额定电流：150 mA（持续）
- 直流电阻（DCR）：约 2 Ω
- 阻抗 @ 10 MHz：约 2 kΩ 与 5.8 kΩ（差模/共模特性在高频段表现不同，共模阻抗通常高于差模阻抗）
- 额定电压：50 V
- 工作温度：-40 ~ +125 °C
- 绝缘电阻：约 10 MΩ（典型）
- 封装：SMD-4P，4.5 × 3.2 mm
三、特点与优势
- 小型化：4.5 × 3.2 mm 紧凑封装，适合高密度 PCB 布局。
- 高共模抑制：10 MHz 处阻抗值较高，有效抑制高频共模噪声。
- 适用温度范围宽：-40 至 +125 °C，满足一般工业级环境要求。
- 易于贴装：SMD 卷带贴片适配自动化生产线，节省装配成本。
四、典型应用场景
- 开关电源输入/输出端 EMI 抑制
- USB、串行接口、传感器信号线的共模干扰抑制
- 通信设备、家用电子及工业控制模块的 EMI 滤波
注意：由于额定电流仅 150 mA，不建议用于大电流电源线上，需根据实际工作电流选择更高电流等级器件。
五、使用与焊接注意事项
- 建议遵循厂商的回流焊工艺建议，避免超出器件耐热极限及剧烈热冲击。
- 在高 DC 偏置下电感值会下降，实际电感与阻抗请在目标电流条件下验证。
- 贴片焊接后建议清洁残留助焊剂以维持绝缘性能与长期可靠性。
- 安装时避免在器件上施加机械应力，焊盘设计应兼顾热膨胀与机械强度。
六、选型与注意事项
- 若电路中直流或纹波电流超过 150 mA，应选用更高额定电流的共模滤波器以避免温升和磁饱和。
- 关注在目标频率范围（如几十 kHz 至几十 MHz）下的阻抗曲线，选择对干扰频段抑制更有效的型号。
- DCR 较高（约 2 Ω）会带来一定的压降与发热，低压差或高精度电源路径需谨慎评估。
七、包装与可靠性
FACT4532-101-2P-T 提供适用于 SMT 贴装的卷带包装，便于自动化生产及库存管理。器件设计考虑了常见工业环境下的温度与绝缘要求，适合大多数消费及工业类电子产品的 EMI 抑制需求。
总结：FACT4532-101-2P-T 以其高共模阻抗、小体积与较宽的工作温度范围，适合对尺寸与 EMI 要求较高但电流较小的应用场景。选择时应重点评估工作电流、频段及 PCB 布局对滤波效果的影响。

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.
