SDCL1005CR27JTDF 产品概述 — Sunlord 0402 贴片电感 270nH ±5% 100mA
一、产品简介
SDCL1005CR27JTDF 为顺络（Sunlord）小型贴片电感，封装0402（1.0×0.5 mm），标称电感值 270 nH，公差 ±5%，额定直流电流 100 mA，直流电阻（DCR）4.5 Ω，品质因数 Q = 8（@100 MHz），自谐振频率（SRF）约 400 MHz。该器件体积极小，适合高密度布板与空间受限的射频/模拟电路中作为频率选择与阻抗元件使用。
二、电气特性要点
- 电感量：270 nH ±5%（公差适中，适用于需要一定稳定性的滤波与匹配）。
- 额定电流：100 mA（为直流热稳定极限，低电流应用为主，不适合大功率或高电流路径）。
- DCR：4.5 Ω（直流下的电阻较大，会带来较明显的功耗）。
- Q 值：8 @100 MHz（中等 Q，说明在射频工作点存在耗损，适用于抑制/阻抗匹配而非高 Q 谐振器）。
- SRF：400 MHz（在此频率附近电感趋近自谐振，工作频率应低于 SRF 的安全区间）。
三、特性与电路影响
由于 DCR 较高，器件在直流及低频下有明显功耗；在 100 MHz 时，感抗 XL ≈ 2πfL ≈170 Ω，Q=XL/Rloss≈8，表明交流损耗（含磁芯损耗与寄生电阻）明显高于 DC DCR。接近或超过 SRF（≈400 MHz）时，电感特性下降并可能表现为容性，应避免在 SRF 附近作为纯感性元件使用。
四、典型应用场景
- 高频差分/共模滤波、信号链的旁路与阻断元件。
- 射频前端的阻抗匹配与窄带抑制（在工作频率远低于 SRF 时）。
- 空间受限的便携式设备、射频模块、小信号滤波电路。
不推荐用于电源滤波（电流需求高）或要求极低损耗的高 Q 谐振电路。
五、PCB 布局与安装建议
- 采用 0402 推荐焊盘尺寸，保证焊点对称，减少热应力。
- 尽量缩短与相邻射频通路的连接线，避免额外寄生电感/电容影响性能。
- 对于多元件滤波网络，注意元件间距以降低耦合。
- 采用标准无铅回流工艺，遵循厂商推荐焊接曲线以保证可靠性。
六、选型与替代考虑
若系统要求更高电流或更低损耗，应选择更大封装或更低 DCR、Q 更高的型号；若工作频率接近或高于 200–300 MHz，应优先考虑 SRF 更高的射频电感或专用磁珠。选型时关注额定电流、DCR、Q 与 SRF 的综合平衡。
七、可靠性与检验
建议按生产检验流程做外观、阻值、感值及高温/回流后测试；在实际设计中做温升与功率损耗评估，确保长期稳定工作。有关更详细的焊接、储存与可靠性数据，请参照顺络官方资料与样品测试报告。

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.
