SDFL1005QR68KTF — 顺络 0402 贴片电感 产品概述
一、产品简介
SDFL1005QR68KTF 是顺络（Sunlord）推出的一款超小型贴片电感，封装规格为 0402（1005公制）。额定电感值 680nH，公差 ±10%，设计用于高密度 PCB 与高频信号链路中的滤波与阻抗控制。该器件具有较高的直流电阻与中频品质因数，适合用于射频匹配、阻抗抑制与窄带滤波场景。
二、主要参数
- 电感值：680 nH ±10%
- 额定电流：15 mA（直流）
- 直流电阻（DCR）：900 mΩ
- 品质因数：Q = 20（@ 10 MHz）
- 自谐振频率（SRF）：70 MHz
- 封装：0402（1005）
- 品牌：Sunlord（顺络）
三、器件特点与工程意义
- 小型化：0402 尺寸适合高密度布板与微型终端设备，节省 PCB 面积。
- 高频性能：Q=20@10MHz 与 SRF=70MHz 表明在中频到低射频范围内具有较好的选择性和能量储存能力。
- 高 DCR 与低额定电流：900mΩ 的直流电阻和 15mA 的电流评级表明该型号更偏向于射频阻抗元件或信号链路用的谐振/阻断元件，不适合作为大电流滤波电感或功率电感使用。
四、典型应用
- 高频信号路径的带通/带阻滤波与谐振回路
- 天线匹配与阻抗调谐电路（低功率射频）
- EMI/EMC 抑制中的高频阻抗元件（信号线级）
- 无线模块、蓝牙/IoT 前端滤波与匹配网络
五、布局与焊接建议
- 尽量缩短与地或相邻网络之间的引线长度，减少寄生电容与电感带来的偏移。
- 当用于滤波或匹配回路时，考虑邻近走线和布线层的耦合，必要时添加地平面隔离或过孔屏蔽。
- 兼容无铅回流焊工艺，建议按 PCB 制造商与芯片厂家的回流温度曲线进行制程验证以避免热应力导致参数漂移或损伤。
- 由于额定电流较低，布线时避免通过该电感的大直流分量，防止温升和电感值下降。
六、选型注意事项
- 若电路需要通过较大直流电流或用于电源去耦，应选择额定电流和 DCR 更适合的功率型电感；本型号适合低功率射频/信号应用。
- 在靠近 SRF（70 MHz）的工作频率时，电感的有效值会显著下降，需在设计阶段进行 S 参数或阻抗测量验证。
- 温度与直流偏置会影响实际电感值，重要设计请索取厂家样品并做实际测试。
七、封装与供应
- 0402 小封装便于大量表贴装配与自动化贴装。
- 建议从正规渠道采购并索取器件样品与规格书（含频率响应曲线、温漂和电流特性曲线）以便在目标应用中做充分验证。
总结：SDFL1005QR68KTF 以其超小体积、良好的中频 Q 值和 70MHz SRF，适合低功率射频滤波、匹配与信号级 EMI 抑制应用；但需注意其 900mΩ 的 DCR 与 15mA 的电流限制，避免用于大电流或低损耗功率场合。

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.
