SDFL1005Q1R0KTF 产品概述
一、产品简介
SDFL1005Q1R0KTF 是顺络（Sunlord）推出的一款超小型贴片电感，封装为 0402（约 1.0 × 0.5 mm），标称电感值 1.0 µH，公差 ±10%。该器件针对小电流、高频信号处理应用设计，体积极小，适合空间受限的移动通信、无线模块与精密测试电路。
二、主要电气参数
- 电感值：1.0 µH ±10%
- 额定直流电流：15 mA（最大工作电流）
- 直流电阻（DCR）：1 Ω
- 品质因数：Q = 20 @ 10 MHz
- 自谐振频率（SRF）：40 MHz
- 封装：0402（贴片）
三、典型特性与解析
- 高频表现：在 10 MHz 时，感抗 XL = 2πfL ≈ 62.8 Ω。结合 Q = 20，可估算等效损耗电阻 Rloss ≈ XL / Q ≈ 3.14 Ω（包含 DCR 与铁损/涡流损耗），说明器件在高频有一定的损耗贡献，应在系统设计中予以考虑。
- 自谐振：SRF = 40 MHz，低于该频率时器件以电感性表现为主；接近或高于 SRF 时电感性降低并可能呈现电容性响应，应避免在 SRF 附近作为理想电感使用。
- 电流能力受限：15 mA 的额定电流限制表明该器件适合小信号或偏置电流场合，不适合作为电源线或大电流滤波元件。
四、典型应用场景
- 射频（RF）信号链中的直流偏置隔离（bias choke）和小电流偏置网络
- 高频滤波与匹配网络（工作频率需低于 SRF）
- 射频前端、收发模块或传感器信号隔离与共模抑制（限于小电流）
- EMI/EMC 抑制中的微型滤波元件，适用于空间受限的消费类电子与通信终端
五、封装与焊接建议
- 封装：0402，适合自动贴装生产。推荐参考厂商数据手册中的 PCB 推荐焊盘尺寸以确保焊点可靠性。
- 回流焊注意事项：采用符合 IPC/JEDEC 的回流温度曲线，避免过高峰值温度和长时间保温以减少热应力。
- PCB 布局：器件两端应有足够焊盘并保证焊锡覆盖均匀，避免在器件下方开孔或放置热源；对高频路径保持短且直，减小寄生电容与寄生电感影响。
六、注意事项与可靠性
- 电流限制：严格遵守 15 mA 额定值，长期超载会导致参数漂移或失效。
- 频率选择：为保证电感特性，应在低于 SRF 的频段使用；若系统工作频率接近 SRF，应进行实际测试验证器件行为。
- 温度与环境：保存与使用应遵循厂商湿敏等级与包装说明，避免潮湿与机械冲击。
- 建议在产品选型阶段参考顺络官方数据手册获取完整的温度特性、频率响应曲线和 PCB 推荐图样，以便在实际设计中正确匹配与验证。
总结：SDFL1005Q1R0KTF 为一款面向小电流、高频小信号应用的 1 µH 贴片电感，体积微小且适合高密度布局，但需关注其 15 mA 的电流限制和 40 MHz 的自谐振频率，以确保在目标电路中的稳定性与性能。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
