FWP252010P-1R5ML 功率电感产品概述

一、产品基本信息

FWP252010P-1R5ML是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,专为小体积、高电流密度的电源电路设计。型号命名清晰传递核心参数:

  • “FWP”为长江微电功率电感系列标识;
  • “252010”对应封装尺寸(公制:长2.5mm×宽2.0mm×高1.0mm,英制等效1008);
  • “1R5M”表示电感值1.5μH(“R”替代小数点),精度±20%(“M”为精度等级代码);
  • 封装形式为SMD-2P(表面贴装双引脚),适配自动化贴片生产,体积紧凑,适合高密度PCB布局。

二、核心电气参数详解

该电感的关键参数直接决定适用场景,具体如下:

  1. 电感值与精度:标称1.5μH,精度±20%,满足工业级电源电路对电感量的基本要求,可覆盖大多数DC-DC降压/升压模块的需求;
  2. 额定电流(Irms):2.5A(交流有效值电流),是电感长期稳定工作的最大电流阈值,超过此值会导致绕组发热加剧,影响使用寿命;
  3. 饱和电流(Isat):2.6A,指磁芯饱和时的电流值——当电流超过Isat,磁芯磁导率急剧下降,电感量骤减至初始值50%以下,可能导致电源输出异常,设计时需保证负载峰值电流低于Isat;
  4. 直流电阻(DCR):76mΩ,为绕组直流电阻,直接影响功率损耗(P=I²×R),76mΩ在同封装电感中属于较低水平,可有效降低电源转换损耗;
  5. 工作温度范围:典型值-40℃~+125℃(磁胶电感通用耐温范围),适配宽温环境应用。

三、结构与封装特点

  1. 磁胶屏蔽结构:采用磁胶包裹绕组,相比传统绕线无屏蔽电感,大幅降低电磁辐射(EMI),减少对周边电路的干扰,适合对电磁兼容(EMC)要求较高的设备;
  2. 小型化封装:2.5mm×2.0mm×1.0mm的超小体积,可有效节省PCB空间,满足智能穿戴、IoT设备等对尺寸敏感的设计需求;
  3. 可靠焊接设计:SMD-2P引脚采用扁平设计,回流焊兼容性好,焊接后抗振动性能优异(可通过10G以上振动测试),适合车载、手持设备等振动环境。

四、典型应用场景

该电感因小体积、高电流、低EMI的特点,广泛应用于:

  1. 消费电子电源:手机、平板、智能手表的DC-DC降压模块(如12V转5V/3.3V),为CPU、内存等核心器件供电;
  2. IoT与可穿戴设备:智能家居传感器(温湿度、运动传感器)、蓝牙耳机的电源管理电路,适配低功耗、小体积需求;
  3. 车载辅助电源:车载USB充电模块、中控显示屏的低功率电源电路(需确认耐温范围符合车载要求);
  4. 小型通信模块:蓝牙、WiFi、LoRa等无线模块的电源滤波,降低信号干扰。

五、性能优势与注意事项

性能优势

  • 高电流密度:2.5A额定电流适配小体积封装,是同尺寸电感中电流性能的突出代表;
  • 低损耗高效:76mΩ DCR减少功率损耗,提升电源转换效率(高负载下优势明显);
  • EMI抑制:磁胶屏蔽降低辐射干扰,减少系统EMC整改成本;
  • 可靠性稳定:长江微电成熟工艺,产品通过RoHS认证,符合环保要求,且经过振动、温度循环等可靠性测试,适合量产。

注意事项

  • 电流限制:长期工作电流不超2.5A(Irms),峰值电流不超2.6A(Isat),避免磁芯饱和或绕组过热;
  • 散热设计:高负载下需保证PCB铜箔宽度≥1.0mm,或增加散热焊盘,避免局部过热;
  • 焊接工艺:回流焊峰值温度控制在245℃以内(时长≤10s),避免磁胶熔化或引脚变形。

六、品牌与可靠性说明

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
