FXL0518-100-M 是长江微电(cjiang)推出的一体成型功率电感,标称电感值 10 μH,公差 ±20%,面向中小功率开关电源滤波与储能场合。封装为 SMD,外形尺寸约 5.2 × 5.4 mm,适合表面贴装自动化生产,具有良好的机械强度和长期可靠性。
说明:DCR 为 155 mΩ 时,在额定电流 2.5 A 下的铜耗约为 P = I^2·R ≈ 0.97 W,需注意器件发热与周边温升。饱和电流 3 A 表示超过该电流时电感无法维持标称储能,电感量会明显下降,应避免长期运行在接近饱和区。
当系统对铜耗、发热或效率要求较高时,若 155 mΩ 的 DCR 导致功率损耗不可接受,应考虑同等电感值但更低 DCR 或更大体积/更高等级额定电流的型号;若空间更受限且电流较小,可选用更小封装但电流等级相应下降的器件。
购买时请向供应方索取详细数据手册和电流-感值曲线、温升测试数据,以便在具体工作条件下评估性能。器件为 SMD 类元件,存储和贴装时请遵循防潮与 ESD 管理规范,避免长期潮湿环境存放。
总结:FXL0518-100-M 以其紧凑的 SMD 封装和较高的饱和电流适合中等功率电源滤波与储能应用,但需重视其 DCR 导致的功率损耗与热管理,合理的电流余量与 PCB 散热设计是保证稳定工作的关键。若需更详细的频率响应、温升或电流偏置曲线,请参考厂方数据手册或联系厂商技术支持。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
