LCXND4040TKL1R0NDG 产品概述
一、产品简介
LCXND4040TKL1R0NDG 为 TAIYO YUDEN(太诱) 生产的一款无屏蔽绕线功率电感，标称电感值 1 µH，公差 ±30%。封装为 1616（即 4040 公制），属于表面贴装器件，适配中高电流的开关电源与滤波应用。本器件通过 AEC-Q200 车规认证，可靠性满足汽车电子环境要求。
二、主要性能参数
- 电感值：1 µH（±30%）
- 额定电流（Irms）：3.2 A
- 饱和电流（Isat）：4 A（在此电流下电感急剧下降，需避免直流偏置接近该值）
- 直流电阻（DCR）：27 mΩ
- 封装：1616（4.0 × 4.0 mm 级别）
- 结构：无屏蔽绕线电感
- 质量等级：AEC-Q200（车规）
三、特点与优势
- 高电流承载能力：3.2 A 额定电流满足多数中功率 DC-DC 降压/升压模块输出滤波需求；4 A 饱和极限提供短时裕量。
- 低 DCR：27 mΩ 有利于降低电阻损耗与温升，典型在额定电流下功率损耗约 0.28 W（P = I^2·DCR）。
- 车规可靠性：通过 AEC-Q200，适用于高温、振动及长寿命的汽车电子应用。
- 无屏蔽设计：利于散热但会有磁通外泄，布局时需考虑与其它敏感元件的间距。
四、典型应用场景
- 汽车电子电源（车载控制单元、电机驱动供电）
- 开关稳压器输出/输入滤波（降压/升压模块）
- 电源管理模块（PMIC）与点对点电源线路
- 工业与通信设备的功率滤波与储能元件
五、选型与使用建议
- 直流偏置与电感降额：在实际电路中，随 DC 偏置增大电感会下降，建议工作电流留有余量（常见设计建议 70%～80% 的裕量）。
- 损耗估算：按额定电流计算的直流损耗约 0.28 W，需在热预算内确认温升与周边器件散热。
- 布局注意：因为无屏蔽，会产生磁场外泄，敏感信号线、电阻/电感等应保持适当间距并使用屏蔽或合理分层布线。
- 焊接与可靠性：遵循厂方推荐的回流焊温度曲线与储存/防潮规范，避免长期超温或机械应力。
六、封装与装配注意
1616 尺寸利于在双面多层板上紧凑布局，建议在电源回路处尽量缩短走线环路面积、在地平面处布置充足散热铜箔并通过过孔散热。若用于汽车关键负载，请配合整机仿真与热试验验证长期可靠性。
如需更详细的频率响应、直流偏置曲线及回流焊工艺参数，请参考 TAIYO YUDEN 正式数据手册或联系供应商获取样品与测量资料。

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.
