SRN8040TA-680M 是 BOURNS 面向功率应用的一款表贴功率电感,标称电感值 68 μH±20%,额定电流 1.65 A,饱和电流(Isat)1.75 A,直流电阻(DCR)约 205 mΩ。器件为 SMD 封装,外形尺寸为 8 × 8 mm,达到车规等级 AEC‑Q200 要求,适合对可靠性有较高要求的嵌入式与汽车电子系统。
总结:SRN8040TA-680M 是一款针对中小电流、需要车规级可靠性的功率电感,具有较大的电感量和明确的电流/饱和界限。设计时应重点关注 DCR 带来的功耗与温升、饱和裕量以及与系统开关频率的匹配,以确保长期可靠运行。若需更详细的电气表征(如频率相关的初始电感、AC 损耗曲线或温度系数)建议参考 BOURNS 的官方规格书或向供应商索取评估数据。

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.
