SDCL1005C1N8STDF 产品概述

一、产品简介

SDCL1005C1N8STDF 是顺络(Sunlord)推出的一款超小型贴片叠层电感,封装尺寸为 0402(1.0 × 0.5 mm 级别)。典型电感值为 1.8 nH,直流电阻(DCR)约为 100 mΩ,额定直流电流 300 mA,品质因数 Q = 8(@100 MHz),自谐振频率(SRF)约为 6 GHz。该器件以体积小、高频性能稳定为特点,适合现代紧凑型射频与高速电路设计。

二、主要电气参数

  • 电感值:1.8 nH(公差请参照厂家规格表)
  • 额定电流:300 mA(须考虑温升和去磁化/饱和效应)
  • 直流电阻:100 mΩ(典型值)
  • 品质因数:Q = 8 @ 100 MHz(表明在射频区仍保持一定的选择性)
  • 自谐振频率:6 GHz(高频截止点,低于 SRF 时表现为电感性)
  • 封装类型:0402 贴片叠层电感

三、特性与应用场景

由于极小封装与较高的自谐振频率,SDCL1005C1N8STDF 适用于:

  • 射频匹配网络与微带线调谐(手机、无线模块、RF 前端)
  • 高速接口的终端匹配与阻抗调节(例如高速差分或单端链路的小阻抗补偿)
  • 带通/陷波滤波器中作为谐振或串联/并联元件
  • 天线馈线的匹配与去耦、微型化滤波器及共模抑制(在合适的对称网络中)
    注意:由于额定电流较低,不适合作为大电流滤波或功率电感使用。

四、设计与PCB 布局建议

  • 封装 0402 体积小,建议采用符合 IPC 标准的 0402 推荐焊盘布局,保证焊盘长度与过孔阻抗控制。
  • 在射频路径中尽量缩短连接走线,减少寄生电容与感抗对目标频率的影响。
  • 若用于匹配网络,应在电路仿真(含封装与 PCB 寄生)后调整电感值与阻抗点。
  • 考虑到 DCR 较高,直流路径上的能量损耗与温升需在电路板热仿真中验证,避免过载导致电感偏离标称值或失效。
  • 对于敏感射频接地,使用适当的地平面并保持足够回流路径。

五、焊接与可靠性处理

  • 推荐采用厂家提供的回流焊工艺曲线(符合无铅回流温度规范与 IPC 要求)。
  • 避免在安装和后工序中对 0402 封装施加过大机械压力,防止陶瓷破裂或端接脱落。
  • 清洗时使用对元件无腐蚀性的溶剂,避免长时间浸泡高温清洗。
  • 存储与搬运应避免潮湿与剧烈振动,必要时按标准进行干燥/烘烤处理以防焊接缺陷。

六、选型注意事项

  • 确认目标工作频段与自谐振频率的关系:SRF 6 GHz 表示在高于该频率时器件转为电容性,设计时应留有裕度。
  • 小电感值与较高 DCR 的组合适合射频匹配而非大电流滤波。
  • 在需要更高 Q 值或更大电流承载能力的场合,可考虑更大封装或不同材料体系的产品系列。

七、结论

SDCL1005C1N8STDF 是一款面向微型化射频与匹配场景的 0402 贴片叠层电感,具有 1.8 nH、SRF ≈ 6 GHz 的高频特性与适中的 Q 值。设计时应充分考虑其电流额定与 DCR 限制,通过电磁与热仿真优化 PCB 布局及回流焊工艺,可在射频前端与高速匹配应用中实现体积与性能的平衡。若需更详细的阻抗/频率特性曲线、精确公差及可靠性数据,请参照顺络官方规格书或联系供应商获取完整数据表。

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.
