FXL0624-150-M 产品概述

一、产品简介

FXL0624-150-M 是长江微电(cjiang)推出的一款一体成型功率电感,标称电感值 15 µH,公差 ±20%,适用于中小功率开关电源与电源滤波场合。器件为表面贴装(SMD)封装,外形尺寸 6.6 × 7 mm,结构紧凑,适合自动化贴装生产。该型号强调大电流能力与良好抗饱和特性,额定电流 2.5 A,饱和电流(Isat)达 3.3 A,直流电阻(DCR)约 160 mΩ。

二、主要性能与特点

  • 标称电感:15 µH,公差 ±20%(常温、无直流偏置测量条件下)。
  • 额定电流:2.5 A(建议长期工作电流,考虑温升与损耗)。
  • 饱和电流(Isat):3.3 A(在此电流附近电感显著下降,须避免长期工作在饱和区)。
  • 直流电阻:约 160 mΩ,导体损耗较为明显,影响系统效率与温升。
  • 结构类型:一体成型(molded),提供较好的机械强度和抗振动性能。
  • 封装与外形:SMD,尺寸 6.6 × 7 mm,兼容自动贴装与无铅回流焊。

三、典型应用场景

  • 同步/非同步降压(buck)转换器的输出滤波电感。
  • 电源管理模块(PMIC)、DC-DC 模块的能量储存元件。
  • 电源输入滤波、降噪或电流峰值限制场合。
  • 工业控制、通信设备与消费电子中需要紧凑封装与中等电流处理能力的电源拓扑。

四、热与电性能考量(设计建议)

  • 损耗估算:DCR = 0.16 Ω 时,导通损耗约为 Pd = I^2 × DCR。以额定电流 2.5 A 计算,Pd ≈ 1.0 W,表明在满载工作时电感本体会产生明显热量,需在系统设计中留有散热空间或采取散热措施。
  • 直流偏置效应:在直流偏置下电感值会下降,接近 Isat 时电感显著降低。设计时应留有裕量(一般建议工作电流远低于 Isat,且考虑最大纹波电流叠加)。
  • 纹波电流管理:建议在选型时评估纹波峰-峰值对电感有效值的影响,避免过大的峰值纹波导致局部磁饱和或过高的温升。
  • 环境与可靠性:建议在目标温度和载流条件下进行热测与寿命评估,确认电感在应用条件下的温升与电感衰减满足系统要求。

五、PCB 布局与焊接建议

  • 布局:将电感尽量靠近开关管或整流二极管/电感所在的关键元件,缩短关键回路的走线以降低环路面积和EMI。输出电容应尽量靠近电感的输出端。
  • 焊盘与固着:遵循厂商推荐的焊盘尺寸,保证焊点充分湿润以降低接触阻抗并增强机械强度。
  • 回流焊:兼容无铅回流工艺,建议遵循 JEDEC 等标准的回流曲线并注意峰值温度及时间,以免影响封装或磁性材料特性。

六、选型与验证建议

  • 若系统效率与温升对设计要求严格,优先选择 DCR 更低或体积更大的替代品,或采用并联电感方案以分担电流与降低损耗。
  • 在最终定型前必须进行样机验证:测量在目标工作点(含最大纹波)下的电感值、温升、效率与磁饱和行为;同时进行长期温度循环与振动测试以验证可靠性。
  • 如需更详细的电磁参数(频率响应、直流偏置曲线、浪涌承受能力等),建议向长江微电索取完整规格书和测量数据。

七、订购信息

  • 型号:FXL0624-150-M
  • 品牌:cjiang(长江微电)
  • 封装:SMD,尺寸 6.6 × 7 mm
  • 主要参数:15 µH ±20%,额定电流 2.5 A,Isat 3.3 A,DCR ≈ 160 mΩ

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
