SRP1770TA-101M 是 BOURNS 推出的表面贴装功率电感器,型号后缀“101”表示电感值为 100 µH,标称精度 ±20%。主要电气参数包括:额定电流 5.3 A、饱和电流(Isat)12 A、直流电阻(DCR)118 mΩ;封装为 SMD,外形尺寸约 17.8 × 16.9 mm,符合 AEC‑Q200 车规等级,适合汽车与高可靠性工业应用。
该器件采用功率级磁芯与较粗铜绕线设计,以支持较大的直流通流能力和能量存储。SMD 形式便于自动贴装(SMT)与回流焊工艺,体积在同类高感量功率电感中属中等尺寸,适合对占板面积与散热有一定要求的电源模块设计。
高 DCR 意味着在高直流电流下会产生较大热量。设计时应:
产品满足 AEC‑Q200 车规等级,表明器件通过了汽车级环境应力与热循环测试,适用于车载电源、车身控制单元及对可靠性要求高的工业控制场景。但在实际车规应用中,仍建议参考厂商完整数据手册进行高温老化、耐振动和冲击验证。
SRP1770TA-101M 为一款面向汽车级与高可靠性电源应用的 100 µH 功率电感器,具有较高的饱和电流裕量(12 A)与中等额定电流(5.3 A)。其较高的 DCR 要求设计者在使用时重视功耗与散热。适合需大储能且对尺寸、车规可靠性有要求的降压与滤波场合。最终设计请以 BOURNS 官方数据手册为准,并在目标系统环境下做全面电热验证。

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.
