顺络SPH4018H1R0NT功率电感产品概述

一、产品基本信息

SPH4018H1R0NT是顺络电子(Sunlord)推出的贴片式功率电感,属于公司针对高密度电源设计开发的高性价比产品线。该产品定位为小体积、高电流的储能元件,广泛适配消费电子、车载及工业控制等领域的电源电路需求。

二、核心电气参数解析

1. 电感值与精度

额定电感值为1μH,精度±30%——符合功率电感的典型精度要求:无需过高精度即可满足DC-DC转换的储能、滤波需求,同时降低设计成本与生产难度。

2. 电流性能参数

  • 额定电流(Iₙ):3.2A
    指电感长期连续工作时的最大允许电流,此时电感升温控制在行业标准范围内(典型≤40K),可保证设备稳定运行。
  • 饱和电流(Iₛₐₜ):4A
    磁芯开始饱和的临界电流——饱和后电感值会显著下降,导致输出纹波增大、开关管损耗增加。设计时需将峰值电流控制在该值以内,避免性能劣化。

3. 直流电阻(DCR)

32mΩ低DCR是核心优势:可有效降低直流损耗,提升电源转换效率(实测可使设备功耗降低1%~2%),尤其适合对效率敏感的便携式设备。

三、封装与物理特性

该产品采用4×4×1.8mm SMD封装,具备以下特点:

  • 小体积高密度:尺寸紧凑,可节省PCB空间30%以上,适配智能手机、智能手表等便携设备的高密度布局;
  • 贴装兼容性:标准SMD焊盘设计,兼容主流自动化贴装设备,生产效率高;
  • 耐温稳定性:采用顺络自研低损耗铁氧体磁芯,工作温度范围覆盖**-40℃~+125℃**,抗振动、耐温变,可靠性强。

四、典型应用场景

结合参数特性,SPH4018H1R0NT广泛应用于:

  1. 便携式电子:智能手机、智能手表、蓝牙耳机的DC-DC降压模块(如5V转3.3V/1.8V);
  2. 小型电源:移动电源升压电路、车载USB充电器、机顶盒/路由器的电源滤波;
  3. 工业控制:小型PLC、传感器模块的低功耗电源电路;
  4. 智能家居:智能音箱、智能门锁的电源管理单元。

五、产品核心优势

  1. 高电流密度:4×4mm小封装实现3.2A额定电流与4A饱和电流,是同类产品中电流性能较优的型号;
  2. 低损耗高效率:32mΩ DCR减少铜损,提升电源转换效率,延长设备续航;
  3. 可靠性强:顺络成熟的磁芯成型工艺,符合RoHS无铅环保要求,通过振动、温循等可靠性测试;
  4. 设计灵活:尺寸符合IPC标准,可与主流电子元器件协同布局,简化电路设计。

六、选型与使用注意事项

  1. 电流余量设计:连续工作电流需低于3.2A,峰值电流不超过4A,避免磁饱和;
  2. 温度降额:若工作环境温度>85℃,需将额定电流降额至2.5A左右,防止过热;
  3. 布局优化:贴装时靠近开关管与输出电容,缩小电流回路面积,降低EMI干扰;
  4. 精度验证:因精度±30%,设计时需在输出电压与纹波规格中预留10%~15%余量,避免电感偏差影响性能。

该产品凭借小体积、高电流、低损耗的特点,成为便携式设备及小型电源电路的理想选择,可有效平衡性能与成本,满足量产需求。

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
