FXL0420-1R5-M 功率电感产品概述
一、概述
FXL0420-1R5-M 为 cjiang（长江微电）出品的一体成型SMD功率电感，标称电感值为 1.5 μH，公差 ±20%。该器件以小封装、高电流承载力为设计目标，适用于开关电源与电源管理模块的滤波与储能场合。封装尺寸 4.2 × 4.4 mm，便于高密度布板和自动贴装。
二、主要参数
- 电感值：1.5 μH（±20%）
- 额定电流（Irms）：5 A
- 饱和电流（Isat，典型定义）：6 A（达到规定直流偏置下电感下降到指定值时）
- 直流电阻（DCR）：46 mΩ
- 类型：一体成型（molded）功率电感
- 封装：SMD，尺寸 4.2 × 4.4 mm
- 品牌：cjiang（长江微电）
三、产品优势
- 高电流承载：5 A 额定电流与 6 A 饱和电流保证在较大负载下维持稳定工作，适合中小功率降压转换器。
- 低DCR：46 mΩ 的直流电阻有助于降低铜损与温升，提高转换效率。
- 一体成型结构：增强机械强度，抗振动性能好，适合汽车电子与工业环境（需参考具体环境规范）。
- 封装紧凑：4.2×4.4 mm 小型化设计，利于高密度PCB布局和多相电源方案。
四、典型应用
- DC-DC 降压（Buck）转换器电感
- 模组电源滤波与能量储备
- LED 驱动与小功率电机驱动
- 通信与工业控制设备的电源管理
五、设计与安装建议
- 布局：电感应尽量靠近开关器件与输出电容，最短化环路以降低辐射与寄生阻抗。
- 温升与散热：按额定电流长期工作会产生热量，建议按系统最高工作温度进行电流退让（derating）设计，避免在高温下超出 Isat 限值。
- 焊接：采用常规回流焊工艺，遵循制造商推荐的温度曲线；焊膏量与焊盘尺寸需匹配，避免过多焊料影响贴装可靠性。
- 测试：建议在目标电路条件下验证电感值随直流偏置与温度的变化，确认在工作点不会出现过度磁饱和。
六、选型注意事项
- 公差 ±20% 对于要求精确临界频率的滤波回路需考虑选用更高精度器件或在电路中调整。
- 饱和电流与额定电流的差异需在设计余量内，短时电流冲击应评估是否会引起磁饱和。
- 若应用涉及汽车等级或更苛刻的环境，请向厂商确认相关可靠性、温度循环与振动测试报告。
FXL0420-1R5-M 以紧凑体积与较高电流能力为特点，适合需要在有限空间内实现高效能量传输的电源方案。具体电气图纸、频率特性曲线与回流焊推荐，请联系长江微电获取完整数据手册与可靠性资料。

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.
