PSTMAA4030-220MB 是谱罗德(PROD)出品的一款扁平线一体成型贴片电感,标称电感值 22 µH(±20%),封装尺寸 4.1 × 4.1 mm,面向中低频电源滤波与储能场合。该器件额定电流 2.5 A,饱和电流(Isat)约 3.4 A,直流电阻(DCR)为 220 mΩ,适合表面贴装自动化生产。
PSTMAA4030-220MB 以其 22 µH 的电感值和一体成型扁平线结构,适用于中低频电源滤波与储能场景。设计时需重视较高的 DCR 带来的功耗与发热,合理选型与 PCB 散热设计能够保证稳定可靠的长期工作。若需更低损耗或更高电流能力,可联系供应商获取更详细的 EMC/频率特性曲线或推荐替代型号。

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.
