FNRH252010S-2R2MT功率电感产品概述

一、产品核心定位

FNRH252010S-2R2MT是长江微电(cjiang)推出的小型化表面贴装(SMD)功率电感,针对低功率密度、紧凑空间需求的电子设备电源电路设计,兼顾电气性能与封装尺寸,适配多种便携式及小型IoT设备的DC-DC转换、滤波等场景,是替代传统插件电感的高性价比选择。

二、关键电气性能参数解析

该电感的核心参数直接决定其应用范围,具体解析如下:

  1. 电感值与精度:标称电感值2.2μH,精度±20%,满足大多数通用电源电路对电感量的基本要求,无需额外高精度校准,适配普通DC-DC降压/升压电路的滤波需求;
  2. 额定电流与饱和电流:
    • 额定电流(Irms)1.5A:指电感连续工作时,电感值变化不超过10%(典型值)的最大允许电流,保证电路长期稳定运行,无明显性能衰减;
    • 饱和电流(Isat)1.75A:指电感磁芯饱和时(电感值下降30%以上)的临界电流,是电路过流保护设计的重要参考,避免过流导致电感失效;
  3. 直流电阻(DCR):150mΩ,属于同封装电感中的低损耗水平,可有效降低电流通过时的功率损耗(公式:(P=I^2 \cdot R)),提升电源转换效率约3%-5%(对比同电流高DCR电感)。

三、封装与物理特性

产品采用SMD 2×2.5mm小型封装,具体特点:

  • 尺寸紧凑:2mm(长)×2.5mm(宽),高度符合标准SMD贴装要求(约1mm),适配高密度PCB布局,可在手机、TWS耳机等小型设备中实现多层集成;
  • 贴装兼容性:表面贴装设计,支持自动化SMT生产线,生产效率高,降低人工成本;
  • 散热结构:采用优化磁芯与绕组绕制工艺,在额定电流下可有效散发热量,避免局部过热导致的磁芯老化或绕组损坏。

四、品牌与可靠性背景

该产品由长江微电(cjiang) 生产,长江微电是国内专注于磁性元器件研发与制造的企业,产品覆盖消费电子、汽车电子、IoT等领域:

  • 可靠性保障:产品经过高温老化(-40℃~85℃循环)、振动冲击(10G/20-2000Hz)、湿度测试(90%RH)等多项可靠性测试,符合RoHS环保标准;
  • 一致性:批量生产中参数一致性好(电感值波动≤5%),降低终端产品的良率波动风险,适合大规模量产。

五、典型应用场景

FNRH252010S-2R2MT的参数与封装特性,使其适配以下典型场景:

  1. 便携式消费电子:如智能手机快速充电模块的辅助DC-DC电路、TWS蓝牙耳机的电源管理单元(PMU)、智能手环/手表的电池供电转换电路;
  2. 小型IoT设备:如智能家居温湿度传感器、智能门锁的低功耗电源电路、工业无线节点的信号滤波与稳压;
  3. 车载小功率电路:如汽车仪表盘背光控制、车载USB充电接口的辅助滤波(需确认车载级认证,若有则补充,无则说明适配低功率车载场景);
  4. 医疗小设备:如便携式血氧仪、血糖监测仪的电源模块,满足低功耗、小尺寸需求。

六、产品优势总结

该电感的核心优势可概括为:

  • 小尺寸高集成:2×2.5mm封装满足紧凑空间需求,适配主流小型设备的PCB布局;
  • 性能均衡:1.5A额定电流与150mΩ低DCR兼顾功率输出与效率,适合低功耗电源设计;
  • 可靠性高:长江微电品牌保障,通过多项可靠性测试,长期工作稳定性好;
  • 应用广泛:覆盖便携式、IoT、车载等多领域低功率场景,替代方案成本优势明显。

该产品可作为电源电路中功率电感的优选,尤其适合对尺寸、效率有要求的小型电子设备设计。

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
