SGM2045-3.30XXDH4G/TR 是圣邦微(SGMICRO)推出的一款超低静态电流、低噪声固定输出线性稳压器,输出电压为 3.3V,最大输出电流 300mA,工作电压最高可达 5.5V。该器件采用紧凑的 XTDFN-4L (1×1 mm) 封装,适合空间受限且对电源噪声及功耗有严格要求的便携与物联网终端应用。
器件集成短路保护与过热保护,当输出短路或过载时,稳压器会进入限制或热关断状态以防止损坏。设计时仍建议在输入侧提供适当的熔断或限流保护以应对异常故障。
型号 SGM2045-3.30XXDH4G/TR 中 “3.30” 表示 3.3V 固定输出,后缀 /TR 通常表示卷盘包装(Tape & Reel),便于 SMT 自动贴装。具体库存与封装可向圣邦微或授权分销渠道确认。

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.
