SDCL0603Q4N7JT02B03 产品概述

一、主要性能与参数

  • 名称:电感(多层片式)
  • 型号:SDCL0603Q4N7JT02B03
  • 品牌:Sunlord(顺络)
  • 封装:0201(微型表面贴装)
  • 电感值:4.7 nH,公差 ±5%
  • 额定电流:350 mA(直流额定)
  • 直流电阻(DCR):400 mΩ
  • 品质因数(Q):13 @ 500 MHz
  • 自谐振频率(SRF):6.2 GHz

二、结构与封装说明

本产品为多层片式(ML)电感,采用0201超小型贴片封装,适合高密度贴装和微型化线路板。0201尺寸提供较小的占板空间,但相对限制了载流能力和散热性能,因此在高电流或高功率场合需谨慎评估。元件本体通常为陶瓷或铁氧体基体上的多层绕线结构,适用于高频信号路径的驻波与匹配处理。

三、性能特点与应用场景

  • 高频性能良好:Q=13 在 500 MHz 时表现出较低的损耗,适合射频匹配网络与高频滤波器的无源元件使用。
  • 宽带工作能力:SRF=6.2 GHz,意味着在数 GHz 以下仍保持电感特性,可用于蓝牙、Wi‑Fi、LTE 前端网络中的耦合/匹配/去耦环节。
  • 微型化设计:0201 封装利于移动设备、穿戴设备、蓝牙耳机、RF 模块与空间受限的射频卡或IoT节点的应用。
  • 典型应用:RF 匹配网络、谐振回路、带通/带阻滤波器、去耦/阻断高频干扰、射频前端小信号滤波及阻抗调节。

四、设计与布局建议

  • 最短走线:在射频路径中应尽量靠近目标节点布局电感,避免长走线和额外寄生电感。
  • 避免过多过孔:通过和长引线会引入额外寄生电感和损耗,影响Q值和谐振点。
  • 地与返流路径:对射频地面处理要均匀,保证良好返流,防止地环路引入噪声。
  • 热与电流裕度:0201 封装热容小,连续工作时建议留有额定电流裕度(特别是直流偏置下会降低有效电感并引起温升),实际设计中建议按应用测试后决定是否降额使用。
  • EMC 与阻尼:用于干扰抑制时,可配合阻尼网络使用以避免高Q导致的峰值响应。

五、可靠性与使用注意事项

  • 焊接工艺:遵循器件制造商的回流焊工艺规范,避免超出峰值温度及滞留时间,推荐参考 JEDEC/IPC 建议的回流温度曲线。
  • 机械应力:0201 封装对片基和焊盘黏着、焊接后的机械冲击较敏感,贴装、剪切和波峰焊工序需控制工艺参数。
  • 环境与老化:高温高湿环境可能影响长期 DCR 与电感值稳定性,应按应用环境做加速寿命验证。
  • 测试项:推荐在实际电路板上进行 S 参数(S11/S21)、Q 值、温升与直流偏置下电感值测量,验证满足目标频段与功率要求。

六、选型与检验建议

  • 若目标频段接近或超过 SRF,需选用更高 SRF 的型号或更大体积的元件以保证电感特性。
  • 对电流或功率有严格要求的场合,应考虑更低 DCR 或更大封装尺寸的替代型号。
  • 采购与样片评估时,向供应商索取完整数据手册、频率响应曲线、温升与电流依赖曲线以及包装(卷带)信息,必要时要求样品进行板上验证。

总结:SDCL0603Q4N7JT02B03 为顺络提供的一款微型高频多层片式电感,4.7 nH、Q 值在中高频段表现良好,适用于占板空间受限、工作频率为数百MHz至数GHz 的射频与 EMI 抑制应用。具体应用前应结合实际 PCB 布局与工况进行频率与热特性验证。若需完整数据手册或样品测试建议联系厂家或授权分销商获取详尽参数。

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
