DLM0QSN900HY2D 产品概述

一、概述

DLM0QSN900HY2D 是村田(muRata)生产的小尺寸共模电感(Common Mode Choke),面向低电流、对电磁干扰(EMI)抑制有严格要求的小型信号线路。器件为表面贴装(SMD)4 引脚封装,适合高密度 PCB 布局与便携式或嵌入式设备的干扰控制需求。

二、主要电气参数

  • 额定电流:50 mA(连续)
  • 阻抗:90 Ω @ 100 MHz(共模)
  • 额定电压:5 V
  • 耐电压(Withstand):12.5 V
  • 直流电阻(DCR):4 Ω
  • 绝缘电阻:≥ 10 MΩ
  • 工作温度范围:-40 ℃ ~ +85 ℃

以上参数为器件典型值或额定值,实际应用时应以厂方最新规格书为准。

三、外形与封装

产品为 SMD-4P 小型封装,标注尺寸约 0.7 × 0.5 mm(资料中亦见 0.6 × 0.5 mm 的记载,请以厂方样本或最新规格书中的外形尺寸为最终依据)。小巧体积便于在受限空间内靠近输入/输出端口布置,提高 EMI 抑制效率。

四、产品特点与优势

  • 小体积、高阻抗:在 100 MHz 附近提供约 90 Ω 的共模阻抗,有效衰减高频共模干扰。
  • 低额定电流设计:50 mA 额定电流适用于微功耗信号链路和接口保护。
  • 良好绝缘与耐压:12.5 V 耐压与 ≥10 MΩ 绝缘电阻,适配低压信号隔离与安全要求。
  • 便于贴片加工:适配常见回流焊工艺,利于自动化贴装和高密度布线。

五、典型应用场景

  • 小型数据接口与串行通信线路(低电流环境)
  • 移动终端、可穿戴设备、物联网节点等空间受限产品的 EMI 抑制
  • 传感器模块与低速差分信号线的共模噪声抑制
    注意:由于较高的 DCR(4 Ω)与低额定电流,不建议用于需大电流或要求极低串联电阻的供电线路。

六、使用与布局建议

  • 布局靠近噪声源或接口端(如连接器或电缆入口),以最大化共模抑制效果。
  • 保持差分/双线对走线对称,避免在电感两端引入不必要的串联阻抗。
  • 在焊盘设计与回流工艺上参照厂方推荐的焊盘尺寸与温度曲线,避免过热或应力集中导致封装损伤。
  • 对于靠近地或高频信号的布线,注意合理安排接地面与过孔,兼顾 EMI 抑制与信号完整性。
  • 由于 DCR 值较大,若电路对电压降敏感或需更高电流,应选择额定电流更高、DCR 更低的器件替代。

七、可靠性与注意事项

  • 工作环境温度范围 -40 ℃ 至 +85 ℃,请在此范围内使用并考虑温升后的性能变化。
  • 对长期可靠性有要求的应用,应根据实际使用条件(温度、湿度、振动)参考厂方的可靠性试验数据。
  • 在高压或脉冲条件下使用前,请验证耐压与绝缘电阻是否满足系统安全裕量。

八、订购与资料确认

型号:DLM0QSN900HY2D,品牌:muRata(村田)。在设计与采购之前,建议下载并核对厂商最新规格书(datasheet)与封装图纸,获取完整的电气特性曲线、焊接指南及环境可靠性数据,以确保器件在目标应用中的匹配与长期可靠性。

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
