Sunlord SPH252012HR24MT 功率电感产品概述

SPH252012HR24MT是顺络电子(Sunlord)针对中低功率电源管理场景推出的贴片功率电感,凭借小体积、高电流承载能力与低损耗特性,成为消费电子、工业控制、车载电子等领域高密度电路设计的优选器件。

一、产品定位与核心设计目标

该电感聚焦DC-DC转换电路的储能与滤波需求,核心设计目标是在紧凑封装下实现“高电流密度+低损耗+宽温可靠性”:既满足便携设备对小体积的要求,又能支撑工业/车载场景的宽温与高可靠性需求,同时通过低DCR降低电源转换损耗,提升系统效率。

二、关键电气参数与设计意义

1. 电感值与精度

标称电感值240nH,精度±20%——适配大多数降压/升压DC-DC电路的电感量需求(常规区间100nH~1μH),20%精度平衡了批量生产的成本与性能,避免因精度过高导致成本上升,同时满足电路对纹波抑制的基本要求。

2. 电流承载能力(额定电流与饱和电流)

额定电流(Irms)与饱和电流(Isat)均为4A——

  • 额定电流是持续工作时电感温升值不超过允许范围的最大电流(顺络常规功率电感温升限制约40℃),4A额定电流可支撑单路输出电流≤4A的电源模块;
  • 饱和电流是电感量下降至标称值80% 时的电流,两者一致说明:4A持续负载下电感无明显饱和,避免储能能力下降导致电源纹波增大、输出电压不稳定,甚至损坏后级器件。

3. 直流电阻(DCR)

直流电阻仅18mΩ——功率电感效率的核心指标:铜损P=I²×R,4A电流下铜损仅0.288W(同类竞品DCR多在25mΩ以上,铜损超0.4W)。低DCR可显著降低电源模块发热,减少散热设计难度,延长设备寿命。

三、封装与物理特性

1. 封装尺寸

采用SMD贴片封装,尺寸标识为252012(公制:2.5mm×2.0mm×1.2mm)或英制1008(0.10英寸×0.08英寸),属于小尺寸功率电感,适合高密度PCB布局(如笔记本主板、小型电源模块的紧凑空间)。

2. 结构与材料

  • 磁芯:顺络优化铁氧体磁芯,提升饱和电流密度,降低高频损耗;
  • 绕线:高导电率漆包线+紧密绕线工艺,减少DCR,提升电流承载能力;
  • 工作温度:常规型号支持-40℃+125℃(车载级可扩展至-55℃+150℃),适应工业、车载宽温环境。

四、产品优势与应用场景

1. 核心优势

  • 高电流密度:252012小封装实现4A额定电流,同类产品中电流承载能力突出,适配“小体积+高功率”设计;
  • 高效率低损耗:18mΩ低DCR+稳定饱和特性,电源转换效率较竞品提升1%~2%,适合对效率敏感的便携设备;
  • 高可靠性:顺络工艺保证批量一致性,符合RoHS/REACH标准,通过振动、冲击测试,适配严苛场景。

2. 典型应用场景

  • 消费电子:笔记本、平板的CPU/内存供电DC-DC模块,小体积适配便携设备紧凑布局;
  • 工业控制:小型PLC、传感器节点电源电路,宽温特性适应车间-20℃~+60℃环境;
  • 车载电子:车载信息娱乐系统、ADAS模块电源管理,满足-40℃~+85℃车载温度要求;
  • 通信设备:小型路由器、交换机电源模块,高密度布局下可并联多个实现多路输出。

五、设计注意事项

  1. 布线时预留散热空间(虽DCR低,但持续高电流仍需考虑散热);
  2. 回流焊需遵循顺络推荐温度曲线,避免磁芯高温损坏;
  3. 若场景电流超4A,需并联多个电感或选择更高电流型号,避免饱和降额。

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
