YLM3225-900T 共模滤波器产品概述

YLM3225-900T是益嘉源(YJYCOIN)推出的一款小型化表面贴装(SMD)共模滤波器,专为抑制电子电路中的共模电磁干扰(EMI)设计,兼具小体积、宽温适应性与高频干扰抑制能力,可满足消费电子、工业控制、汽车电子等多领域的低功耗、高密度布局需求。

一、产品核心定位

该产品属于双路SMD共模滤波器,核心目标是在紧凑空间内实现对高频共模噪声的有效抑制,同时保持低直流损耗与宽环境温度耐受能力。其设计针对100MHz左右的常见EMI频段(如无线通信相邻干扰、开关电源噪声等),可适配多数小功率电路的电流与电压需求,是高密度PCB设计中解决EMI问题的优选组件。

二、关键参数深度解析

共模滤波器的性能由阻抗特性、电流/电压能力、直流损耗及环境适应性决定,YLM3225-900T的参数具备明确应用针对性:

  1. 通道与阻抗特性:双路设计支持两路信号/电源同时滤波;90Ω@100MHz的共模阻抗是核心优势——100MHz为多数设备的关键EMI频段(如WiFi二次谐波、开关电源高频噪声),该阻抗可有效衰减共模噪声,且对差模有用信号衰减极小,不影响电路传输。
  2. 电流与电压能力:额定电流1A满足多数小功率电路(传感器、MCU电源、低功耗通信模块)持续工作需求;额定电压50V覆盖3.3V~48V低压直流范围,无需额外降额,适配性强。
  3. 直流损耗与效率:DCR 50mΩ实现低功耗——1A电流下直流功耗仅0.05W(I²R=1²×0.05),发热极小,长期工作稳定性高。
  4. 环境适应性:**-40℃~+125℃**宽温范围通过极端温度测试,可适配户外安防、车载电子、工业PLC等场景的温度变化。

三、封装设计与生产适配性

采用3.2×2.5×2.2mm SMD封装(3225封装),具备以下优势:

  1. 小体积高密度:紧凑尺寸适配智能手机、智能穿戴、微型通信模块等对体积敏感的产品,节省PCB空间;
  2. 自动化贴装兼容:符合SMT标准,可通过常规贴装设备快速生产,降低制造成本;
  3. 焊接可靠性:结构优化可承受无铅焊接260℃峰值温度,不易出现虚焊、脱落,机械稳定性强。

四、典型应用场景

结合参数特性,产品覆盖以下领域:

  1. 消费电子:手机、平板、智能手表的电源/信号线路(USB、音频接口),抑制无线干扰与电源噪声;
  2. 工业控制:PLC模块、工业传感器、伺服驱动器的信号滤波,提升现场抗干扰能力;
  3. 汽车电子:车载摄像头、胎压监测(TPMS)、车载通信模块的电源/信号线路,满足车载EMC与宽温要求;
  4. 通信设备:路由器、交换机、无线AP的以太网/射频前端线路,抑制高频噪声,提升通信稳定性。

五、产品选型优势总结

相较于同类3225封装产品,YLM3225-900T具有差异化优势:

  1. 高频针对性强:90Ω@100MHz精准覆盖关键EMI频段,抑制效果优于通用型;
  2. 低功耗设计:50mΩ DCR大幅降低直流损耗,适合长期低功耗场景;
  3. 宽温可靠性:-40℃~+125℃超出多数消费类产品需求,适配工业与车载场景;
  4. 品牌品质保障:益嘉源产品经高低温循环、振动测试,一致性好,可靠性高。

该产品平衡体积、性能与可靠性,为多领域EMI问题提供高效低成本解决方案,是电子设计中解决共模干扰的实用选择。

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.

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
