VLS252012CX-100M-1 产品概述
一、产品简介
VLS252012CX-100M-1 是 TDK 推出的功率电感，属于小尺寸表面贴装电感器系列。主要参数如下：标称电感值 10 µH，公差 ±20%；额定电流（Irms）790 mA；饱和电流（Isat）790 mA；直流电阻（DCR）402 mΩ；封装为 1008 型号，适配 SMT 安装工艺。该器件面向需要占板面积小且具备一定电流承载能力的电源滤波和储能场景。
二、主要特性
- 小尺寸 SMD 封装（1008），便于高密度板级布局。
- 电感量 10 µH，适合低频滤波与能量存储用途。
- 额定电流与饱和电流均为 790 mA，说明在接近该电流时可能出现显著磁饱和，选型时需注意裕量。
- DCR 为 402 mΩ，相对较高的直流电阻会带来较大的 I^2R 损耗，需要在效率和温升之间权衡。
- 公差 ±20%，适用于对电感精度要求不严格的电源应用。
三、典型应用场景
- 降压（Buck）DC-DC 转换器的输出滤波电感。
- 电源输入/输出滤波，减少电源纹波与噪声。
- 电源管理芯片（PMIC）和便携式终端的电源模块。
- LED 驱动和小功率电源模块中作为能量储存元件。
四、选型与使用建议
- 留足饱和裕量：由于 Isat 与额定电流相同，建议实际电路中工作电流留有 20%~50% 的裕量以避免磁饱和导致电感值下降。
- 考虑纹波电流与 DCR 损耗：直流电阻 402 mΩ 会带来明显的功耗与温升，需评估器件在最大工作电流下的温升及对系统效率的影响。
- 验证工作频率：在高开关频率场合应参考厂方频率特性曲线，确认铁心损耗与纹波抑制能力满足要求。
- SMT 焊接与热管理：遵循 TDK 推荐的贴片与回流焊工艺，合理安排散热路径与布局，避免长期高温影响可靠性。
五、布局与测试要点
- 近源布置：在开关电源中尽量将电感靠近开关器件或输出电容，缩短信号环路，降低 EMI。
- 温升测试：在典型工作条件下测量温升与效率，必要时评估散热改进方案。
- 实测电感与饱和特性：在目标电流与温度条件下测量实际电感值，确认无不期望的饱和或线性劣化。
六、采购与资料
购买时请确认型号全称 VLS252012CX-100M-1 并参考 TDK 官方数据手册获取更详细的频率特性、温度特性和推荐焊接工艺。在量产前建议进行样品验证、环境与寿命试验以保证长期可靠性。
总结：VLS252012CX-100M-1 以其小型封装和 790 mA 的电流等级适合体积受限的电源滤波与能量储存场合，但较高的 DCR 与饱和参数要求在设计时重视热耗与饱和裕量，结合实测数据可获得稳定可靠的电源性能。

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.
