VLS252010HBX-100M-1 产品概述
一、主要参数
- 电感值：10 µH（公差 ±20%）
- 额定电流（Ir）：680 mA
- 饱和电流（Isat）：680 mA（在该电流下电感降至规定比例）
- 直流电阻（DCR）：460 mΩ
- 品牌：TDK
- 封装：1008
二、产品特性
VLS252010HBX-100M-1 为功率用片式电感，10 µH 的电感量适用于中低频开关电源与滤波场合。较高的 DCR（460 mΩ）提示在接近额定电流时存在明显的 I²R 损耗，器件热升高需重视；同时 Isat 与额定电流接近，说明在设计中应考虑电流裕量以避免电感值显著下降。封装为 1008，适合高密度贴片布局。
三、典型应用场景
- 开关电源（小功率 Buck/Boost）与输出滤波
- 电源噪声抑制与 EMI 滤波网络
- 可穿戴、物联网终端等低功耗设备的能量传输与滤波
- 传感器供电与模块隔离电路
四、选型与使用建议
- 电流裕量：由于 Isat 与额定电流相同，建议在设计中将最大连续电流控制在 Isat 的 60%–80% 范围内（视系统允许的电感降幅而定），以保证工作电感稳定。
- 损耗评估：在满载 680 mA 时，理论损耗 P ≈ I²·DCR ≈ 0.68²×0.46 ≈ 0.21 W，应评估系统温升并预留散热空间。
- 频率匹配：10 µH 适用于较低开关频率或用于输出端较大滤波量的场合，高频下要关注磁芯损耗与增益响应。
- PCB 布局：器件靠近开关节点或受干扰端放置，走线尽量短且粗，必要时添加散热铜箔或过孔以降低结温。
五、注意事项
- 直流偏置效应：实际工作中直流电流会导致有效电感下降，需在电路仿真或测量中考虑该效应。
- 温度与可靠性：长期在高温或接近饱和电流工作会加速性能退化，建议进行热仿真与寿命验证。
- 噪声与共振：与输入/输出电容配合时注意 LC 谐振，必要时加入阻尼或选型调整电容值。
六、采购与替代
在选型时可参考同系列或相近电感值、相似封装的产品以满足不同电流或 DCR 要求；如需更低 DCR 或更高饱和电流，应优先查阅 TDK 完整系列数据表并与供应商确认实际样品性能。
如需我帮您基于工作电流、开关频率与允许损耗筛选更合适的替代型号或给出 PCB 布局示意要点，可提供目标工况（电流峰值/均值、允许温升、开关频率等）。

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.
