FXL0630-3R3-M 产品概述

一、产品简介
FXL0630-3R3-M 是长江微电(cjiang)推出的一款一体成型功率电感,额定电感值为 3.3µH(公差 ±20%),面向中高电流开关电源与电源管理应用。器件采用 SMD 封装,外形尺寸 6.6 × 7.0 mm,结构紧凑,便于表面贴装和高密度布板。

二、主要参数

  • 电感值:3.3 µH ±20%
  • 额定电流(Ir):8.5 A(连续工作建议值)
  • 饱和电流(Isat):9.5 A(基准电流下电感降至额定值的显著比率)
  • 直流电阻(DCR):约 22 mΩ(典型值)
  • 封装:SMD,一体成型,尺寸 6.6 × 7 mm

三、产品特点

  • 高电流能力:额定电流 8.5A、饱和电流 9.5A,适合大电流降压转换器与电源滤波场合。
  • 低 DCR:约 22 mΩ 的低直流电阻有助于降低功率损耗与发热,提升转换效率。
  • 结构坚固:一体成型封装提高机械强度与抗振动性能,利于自动化贴装与回流焊工艺。
  • 小型化:6.6×7mm 尺寸在保证电流容量的同时有利于高密度电路板设计。

四、典型应用

  • 同步降压(Buck)/ 升压(Boost)转换器的储能/滤波电感
  • DC-DC 电源模块与电源管理单元(PMU)
  • LED 驱动、电机控制与便携设备电源
  • 工业与通信设备中的高功率开关电源

五、设计与使用建议

  • 饱和裕量:为避免电感值在瞬态峰值电流下显著下降,建议在选型时预留至少 10–20% 的电流裕量。
  • 布局与散热:靠近电源开关器件布置,保证回流路径短且宽;器件大电流下会产生热量,注意底层铜厚与散热设计。
  • 焊接工艺:兼容标准无铅回流焊工艺,建议根据 PCB 板材与元件资料调整回流曲线以保证焊点可靠性。
  • 验证测试:在目标应用温度与频率下验证实际电感、DCR 及温升,必要时在样机上做长期老化与冲击振动测试。

六、选型与采购提示
在同等电感值下,关注 DCR 与 Isat/Ir 的实际测试曲线;对关键应用建议索取样品进行实测。订货时确认包装、最小订购量与可追溯批次信息,以便质量控制与量产一致性。

如需本型号更详细的电气特性曲线、温升数据或推荐的 PCB 焊盘尺寸,可提供后续支持与样品申请渠道。

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.

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
