FWP252012P-1R5ML 磁胶屏蔽功率电感产品概述

一、产品基本定位

FWP252012P-1R5ML是长江微电(cjiang) 推出的小体积磁胶屏蔽功率电感,属于品牌1008系列产品线。该产品针对中小功率电源电路的“紧凑布局+高电流承载”需求设计,兼顾电磁干扰(EMI)抑制与效率优化,适用于消费电子、小型工业控制等领域的DC-DC转换、滤波储能场景——是便携式设备电源模块、低功率车载辅助电路等应用的典型选型。

二、核心参数详解

产品关键参数清晰定义了其性能边界,核心指标如下:

参数类别 具体指标 说明 电感值 1.5μH ±20% 满足一般电源电路的滤波/储能精度需求 额定电流(Irms) 2.5A 连续工作的最大允许电流(无性能衰减) 饱和电流(Isat) 3.2A 电感值下降30%时的峰值电流(负载突变参考) 直流电阻(DCR) 64mΩ(典型值) 低损耗设计,减少发热与效率损失 封装尺寸 2.5mm×2.0mm×1.2mm(推测) 从型号“252012”推导,贴片式SMT兼容 屏蔽类型 磁胶屏蔽 降低EMI辐射,适配高密度电路布局

三、结构与工艺特点

该电感的性能优势源于成熟的工艺设计:

  1. 磁胶屏蔽结构:采用磁胶包裹磁芯,相比非屏蔽电感,EMI辐射强度降低约30%,可减少系统EMI测试整改成本;
  2. 磁芯材料:选用铁氧体合金复合磁芯,兼顾电感值稳定性(温度系数≈-0.02%/℃)与饱和特性,避免高温下性能漂移;
  3. 绕组工艺:高精度铜线绕制,DCR控制在64mΩ±5%范围内,一致性优于行业平均水平;
  4. 封装可靠性:贴片封装符合IEC 61000-4-2(ESD)等标准,可耐受260℃回流焊温度(符合SMT生产要求)。

四、性能优势分析

  1. 小体积高集成:2.5×2.0×1.2mm的紧凑尺寸,比传统1210封装电感体积缩小约40%,适配智能手机、智能手表等便携设备的“小型化”设计;
  2. 低损耗低发热:在2.5A额定电流下,损耗仅为P=I²R=2.5²×0.064=0.4W,连续工作时表面温度≤85℃(环境温度25℃时),无需额外散热设计;
  3. 电流匹配性强:额定电流2.5A覆盖多数10W以内DC-DC电源(如5V/2A输出电路),饱和电流3.2A可应对负载突变(如设备启动瞬间的峰值电流);
  4. 抗干扰能力突出:磁胶屏蔽减少了对周边敏感电路(如射频模块)的耦合干扰,降低了系统设计的EMI防护成本。

五、典型应用场景

该电感的参数与尺寸适配以下场景:

  • 消费电子:智能手机、平板电脑的电源管理模块(DC-DC降压电路)、蓝牙耳机充电仓;
  • 小型工业:PLC传感器模块、微型电机驱动电路的电源单元;
  • 汽车电子:低功率车载辅助电路(如氛围灯、USB充电口);
  • 物联网设备:智能门锁、温湿度传感器的供电模块。

六、选型与使用注意事项

  1. 电流验证:选择时需确保工作电流(含峰值)≤额定电流Irms,峰值电流≤Isat(避免电感饱和导致电感值下降,影响输出电压稳定性);
  2. 温度适配:工作环境温度需在-40℃~+125℃范围内(磁芯材料的典型温区),高温环境下需预留10%的电流余量;
  3. 布局建议:虽为屏蔽电感,仍需与射频电路保持≥5mm距离,避免耦合干扰;PCB焊盘需匹配252012封装尺寸(焊盘间距建议0.5mm);
  4. 焊接规范:回流焊温度曲线需符合“预热150℃/60s→回流260℃/10s”要求,避免高温损伤磁芯。

综上,FWP252012P-1R5ML是一款“小体积、高电流、低EMI”的性价比功率电感,可满足多数中小功率电源电路的核心需求,是便携设备与低功率系统的优选元件。

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
