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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
