SRN8040TA-100M 是 BOURNS 提供的一款车规级半屏蔽片式功率电感,标称电感值为 10 µH(±20%)。器件体积小巧(8.0 × 8.0 × 3.7 mm),为 semi-shielded SMD 结构,适合用于空间与散热受限的电源设计,特别满足汽车级(AEC‑Q200)可靠性要求。该型号在高电流应用中具备较好的电流承载能力和抗饱和性能,可用于多种开关电源与点式负载(PoL)场景。
注:在 4.6 A 连续条件下,基于 DCR 33 mΩ 的 I^2·R 损耗约为 0.7 W(4.6^2 × 0.033 ≈ 0.7 W),实际发热受散热条件与频率相关损耗影响,需在热设计中考虑裕量。
该器件为半屏蔽设计,能在一定程度上降低磁场对周围元件的干扰,但屏蔽程度低于全屏蔽类型,优势在于更低的成本和更好的散热路径。封装尺寸为 8×8×3.7 mm,占板面积较小但高度适中,适合中高电流 DC‑DC 升/降压应用。厂商标注为“非标准”封装,建议在 PCB 设计前获取厂家推荐的焊盘尺寸与 3D 模型进行验证。
SRN8040TA-100M(10 µH,±20%,Irated ≈4.6 A,Isat ≈5 A,DCR ≈33 mΩ,8×8×3.7 mm,AEC‑Q200)是一款面向车规和工业中高电流点的半屏蔽 SMD 功率电感,兼顾电流承载能力与散热性能。选用该器件时,应重点关注工作点电流、DC 偏置下电感衰减、热管理与 PCB 布局,并参考 BOURNS 的详细数据手册以获得完整的电气、热和机械规格。若用于量产或严格车规项目,建议与供应商确认封装与可靠性试验报告,确保在目标应用环境下的长期稳定性。

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.
