YLPTEC B0503S-1WR2是一款小功率隔离降压电源模块,专为5V系统设计,核心功能是将4.5V~5.5V输入电压稳定转换为3.3V输出,同时提供1.5kVrms电气隔离。该模块针对工业级应用优化,兼顾可靠性与易用性,适合需要紧凑尺寸、隔离防护的低功耗设备供电场景,无需额外外围电路即可直接使用。
内置短路保护功能,当输出端意外短路时自动切断输出,故障排除后自动恢复,可有效保护模块与负载免受损坏,降低现场维护成本。
支持**-40℃~+105℃工业级温度范围**,可适应户外、工业现场等极端环境(如冷库、高温车间),无需降额使用,可靠性符合工业设备要求。
模块采用插件式封装,物理尺寸为长11.6mm×宽6mm×高10.16mm,体积紧凑,可轻松集成到小型设备(如手持仪器、控制板、智能家居节点)中。插件引脚布局合理,焊接时不易出现虚焊,提升生产效率。
YLPTEC B0503S-1WR2通过了宽温测试、短路保护测试及隔离耐压测试,可满足工业级应用的可靠性要求。其紧凑尺寸、隔离防护与低待机功耗的特点,使其成为5V转3.3V隔离供电场景的高性价比选择。

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.
