SRR1208-100ML 产品概述

一、产品简介

SRR1208-100ML 是 BOURNS 提供的一款屏蔽绕线贴片电感,标称电感值 10µH,公差 ±20%,适合中高电流的电源滤波与储能场合。封装为 SMD,外形尺寸 12.7 × 12.7 mm,结构为屏蔽绕线以降低磁辐射和相互干扰,规格面向对电磁兼容性和功率密度有要求的应用。

二、关键电气参数

  • 电感值:10 µH(±20%)
  • 额定电流:5 A(连续工作建议值)
  • 饱和电流 (Isat):6.7 A(磁芯开始明显降感时的参考值)
  • 直流电阻 (DCR):最大 21 mΩ
  • 类型:屏蔽绕线电感(非标准型号)

三、性能与应用意义

屏蔽绕线结构有利于抑制漏磁,适用于开关电源输入/输出滤波、降压(Buck)电路、LED 驱动、电机驱动及通讯设备电源模块。较低的 DCR 有利于降低导通损耗,但在满载时仍需关注 I²R 发热。例如在额定电流 5 A 下,损耗约为 0.525 W(P = I²·DCR),需采取良好散热和布板措施。

四、选型与使用建议

  • 连续电流优先以额定电流为准,若存在大幅峰值脉冲,请以饱和电流 Isat 作为峰值参考并保留裕量。
  • DCR 影响效率与发热,系统设计时应计算功耗并验证温升,以免超过器件或周边元件的温度限制。
  • 屏蔽型利于降低 EMI,但仍需配合布局、走线和旁路电容进行系统级抑制。
  • 由于为非标准款,采购时确认交期与最小起订量。

五、封装与焊接注意

SMD 12.7×12.7 mm 尺寸便于自动贴装。推荐按照制造商的回流焊工艺曲线进行焊接,避免过猛的温度梯度或机械应力导致绕组损伤。焊盘设计应兼顾机械支撑与热散发,必要时在器件下方或附近提供铜层以利散热。

六、可靠性与测试

在验证阶段应进行电感值、直流电阻、温升、耐振动与冲击测试;并在工作温度范围和典型开关频率下测量实际电感与损耗。对关键应用(如汽车、工业)建议遵循相应的环境与寿命规范进行评估。

七、总结

SRR1208-100ML 以 10µH、5A 连续电流、低 DCR(≤21 mΩ)和屏蔽绕线结构,适用于需要较高电流处理能力且注重 EMI 控制的电源与滤波场合。选用时应重视饱和电流和温升评估,并与供应商确认非标准型号的供货与技术资料。

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.

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
