SDFL1005Q1R5KTF 产品概述(顺络 / 0402 贴片电感 1.5µH ±10%)

一、产品简介

SDFL1005Q1R5KTF 是顺络(Sunlord)推出的一款超小型 0402 封装贴片电感,标称电感值 1.5µH,公差 ±10%,直流电阻 (DCR) 约 1.4Ω,额定电流 15mA,品质因数 Q = 20(@10MHz),自谐振频率(SRF)约 30MHz。该元件以体积小、频率特性稳定为主要优势,适合高密度贴片化电路中的信号滤波与阻抗匹配应用。

二、主要电气参数

  • 电感值:1.5µH ±10%
  • 额定电流:15mA(注意非大电流器件)
  • 直流电阻(DCR):约 1.4Ω
  • 品质因数:20(测试频率 10MHz)
  • 自谐振频率(SRF):约 30MHz
  • 封装尺寸:0402(约 1.0×0.5mm)
  • 封装形态:贴片,适合自动贴装与回流焊工艺

三、性能特点

  • 小尺寸、高密度:0402 封装适用于空间受限的移动、便携与高密度主板设计。
  • 高频性能良好:Q 值在 10MHz 附近较高且 SRF 约 30MHz,适用于中高频滤波与阻抗调整。
  • 低电流应用定位:15mA 的额定电流决定其不适合做功率传输或大电流滤波,而更适合信号链路或弱电滤波。
  • 稳定性与一致性:顺络生产工艺确保电感值与 DCR 在批次间的一致性,便于批量生产控制。

四、典型应用场景

  • 高频信号滤波:用于 RF/IF 前端或模拟信号链路中的 LC 低通/带通滤波器与阻抗匹配。
  • EMI/ESD 抑制:在数据线或控制信号线上作为高频去耦或噪声滤波元件使用。
  • 移动设备与智能终端:适合对体积有严格要求的无线模块、传感器接口与射频子模块。
  • 仪表与精密电子:用于小电流测量电路或模拟前端的滤波与噪声抑制。

五、设计与使用注意事项

  • 电流与饱和:额定电流较低,设计时必须保证通过该电感的直流/脉冲电流远低于 15mA,以避免电感值下降或磁饱和。
  • 频率范围:工作频率应低于自谐振频率 30MHz 的安全范围内,以确保电感行为为感性而非容性。
  • 热与焊接:建议遵循厂家回流焊工艺说明进行焊接,避免超过器件耐热极限与长时间高温暴露。
  • 布局考虑:贴片体积小,焊盘设计与贴装精度对电感性能与可靠性影响较大,建议参考顺络的 PCB 布局与焊盘推荐图。
  • 测量条件:Q 值、SRF 等参数与测试电路及频率有关,应用时应在目标频段内做原型验证。

六、选型建议与替代方案

  • 若应用为信号或 RF 频段滤波且电流需求小,SDFL1005Q1R5KTF 是合适选择。
  • 若需要更大电流承载能力或更低 DCR,应考虑更大封装或专用电源电感件(如 0805 及以上封装的功率电感)。
  • 在频段接近或超过 30MHz 的应用,应评估 SRF 对电路的影响,必要时选用更高 SRF 的器件或减少电感值以保证工作特性。

总结:SDFL1005Q1R5KTF 以其微小封装与良好的高频特性适用于空间受限且电流需求较低的滤波与匹配场合。具体性能与可靠性建议参照顺络官方 datasheet 与应用手册,在实际电路中进行验证。

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
