FACT4532-220-2P-T是长江微电(cjiang)推出的双绕组共模滤波器,核心参数如下表所示:
参数项 规格值 备注 通道数 2(共模双绕组) 对称设计 电感量(@100kHz) 22uH 典型共模干扰测试频率 阻抗特性(典型值) 500Ω@10MHz;1.2kΩ@10MHz 高频干扰抑制参考 额定直流电流(Idc) 200mA 连续工作电流上限 额定交流电压(Vac) 50V 绝缘耐压要求 直流电阻(DCR,单绕组) 1Ω 低损耗设计 工作温度范围 -40℃ ~ +125℃ 宽温覆盖工业/消费场景 绝缘电阻(25℃) ≥10MΩ 引脚间绝缘要求 封装类型 SMD-4P(表面贴装4引脚) 自动化贴装适配 封装尺寸 4.5mm×3.2mm(长×宽) 小型化高密度布局精准共模干扰抑制
双绕组对称设计,22uH电感量在100kHz频段具备稳定的共模噪声衰减能力;10MHz下的高阻抗值可有效过滤射频段干扰,满足多数电路的EMC电磁兼容要求。
低损耗高效能
单绕组直流电阻仅1Ω,额定200mA电流下总损耗(双绕组串联)≤0.08W,不会对电路效率造成明显影响,适合对功耗敏感的小电流场景。
宽温稳定工作
-40℃至+125℃的温度范围,覆盖工业现场、车载辅助电路及消费电子的高低温应用,长期工作无性能衰减。
小型化封装适配
4.5×3.2mm SMD-4P封装体积紧凑,适配高密度PCB布局;引脚间距符合标准规范,支持自动化贴装,提升生产效率。
安全可靠设计
50V额定电压满足低压电路绝缘要求,10MΩ以上绝缘电阻可防止引脚间短路,保障电路长期稳定运行。
该器件针对小电流电路的EMI抑制需求设计,典型应用包括:
采用无铅环保SMD-4P封装,机械尺寸及工艺要求:
FACT4532-220-2P-T是一款高性价比的小型化共模滤波器,凭借精准的干扰抑制、低损耗、宽温稳定及自动化适配等特点,成为消费电子、小型电源、通信及工业控制领域电路EMC整改的理想选择,可有效降低电磁干扰对电路的影响,提升系统稳定性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
