FXL0624-6R8-M 功率电感产品概述

一、产品基本信息

FXL0624-6R8-M是长江微电(cjiang)推出的一体成型贴片功率电感,属于中功率电感系列。其命名遵循行业通用逻辑:

  • “FXL”为产品系列代码(长江微电功率电感系列标识);
  • “0624”对应封装尺寸参数(实际尺寸为6.6×7mm,适配小型化PCB布局);
  • “6R8”表示标称电感值为6.8μH;
  • “M”代表电感精度为**±20%**。

产品采用SMD(表面贴装)封装,可直接兼容自动化贴片生产流程,无需额外插件工序,适合批量电子设备制造。

二、关键性能参数详解

1. 电感值与精度

标称电感值为6.8μH,精度±20%,满足多数中功率电源电路的设计需求(如DC-DC降压电路的电感选型)。该精度水平可覆盖90%以上的消费电子、车载电源场景,无需额外高精度要求。

2. 电流能力

  • 额定电流(Irms):4A
    指产品在连续工作状态下,电感值变化不超过10%的最大电流(行业常规标准),是电源电路持续负载的核心参考(如笔记本电脑CPU供电的持续电流需求)。
  • 饱和电流(Isat):6A
    指电感值下降30%时的最大电流,适用于电路瞬态电流峰值需求(如开机瞬间、负载突变时的电流冲击),为设计提供安全余量,避免电感饱和导致电路失效。

3. 直流电阻(DCR)

低至70mΩ,属于同尺寸电感中的中低阻水平。低DCR可有效降低电流通过时的功耗(公式:(P=I^2R)),减少电源电路的热损耗,提升整体转换效率。

4. 封装尺寸

实际尺寸为6.6mm(长)×7mm(宽),高度参数虽未明确标注,但一体成型电感通常高度≤5mm,可适配紧凑的PCB布局(如笔记本电脑主板、车载中控模块)。

三、产品设计特点与优势

1. 一体成型结构的核心优势

  • 低电磁干扰(EMI):磁芯与线圈一体化封装,减少磁泄漏,降低对周边电路的信号干扰,适合对EMI要求较高的通信、车载设备。
  • 高可靠性:无传统绕线电感的线圈裸露问题,耐振动、抗冲击性能优异(可通过振动测试标准),适配车载、工业设备等严苛环境。
  • 宽温稳定性:磁芯材料稳定,电感值随温度变化小(工作温度范围通常为-40℃~125℃),保证电路在极端温度下的性能一致性。

2. 性能平衡设计

额定电流4A与饱和电流6A的搭配,兼顾连续负载能力与瞬态电流余量;低DCR(70mΩ)进一步提升电源转换效率,降低系统功耗,适合对能效有要求的电子设备。

四、典型应用场景

FXL0624-6R8-M的参数特性使其适配多类中功率电子设备的电源电路:

  1. 消费电子:笔记本电脑、平板电脑、便携式充电器的DC-DC降压模块(如给CPU、内存供电的中功率电路);
  2. 车载电子:车载中控、仪表盘、行车记录仪的电源管理单元(PMU),利用其耐振动、宽温特性适配车载环境;
  3. 通信设备:路由器、交换机、基站小模块的电源电路,低EMI特性减少信号干扰;
  4. LED驱动电源:中功率LED照明(如室内面板灯、路灯模块)的降压驱动电路,满足电流与电感值需求。

五、选型与使用注意事项

  1. 电流余量设计:连续负载电流建议不超过额定电流的80%(即3.2A以内),避免长时间满负载导致温度过高;瞬态峰值电流需控制在6A以下,防止电感饱和。
  2. 精度适配:±20%的精度可满足多数电源电路,若需更高精度(如±10%)需更换其他型号。
  3. 焊接工艺:SMD封装需遵循回流焊参数(峰值温度240℃~260℃,时间≤30秒),避免焊接温度过高损坏产品。
  4. 散热设计:大电流工作时需保证PCB有足够的散热铜箔,避免局部过热影响产品寿命。

总结

FXL0624-6R8-M凭借一体成型结构的高可靠性、低EMI,以及平衡的电流与电感参数,成为中功率电源电路的实用选型,适用于消费电子、车载、通信等多领域,可有效降低系统功耗与设计复杂度。

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.
