B0505S-2WR3 是 YLPTEC(易川)推出的一款单通道隔离式 DC-DC 电源模块,输出功率 2W,输入工作电压范围 4.5V ~ 5.5V,输出稳压 5V,最大输出电流 400mA。模块采用紧凑 SIP 封装(19.5 × 7 mm),具有高达 1.5kV 的输入/输出间隔离能力,适用于对地隔离、信号隔离与电源去耦的小功率场合。
按典型效率与满载计算的输入电流约为 Iin ≈ Pout/(Vin·η) ≈ 2W/(5V·0.84) ≈ 0.48A,设计时建议留有裕量。
模块具备短路保护与低功耗特性,能在异常负载或短路条件下保护自身及外接电路,降低系统风险。同时待机与空载损耗较低,适合对功耗敏感的电池供电或低功耗系统。具体的短路恢复行为与限流特性建议参考厂方详细数据手册以获得准确工作模式说明。
SIP 小型封装(19.5×7 mm),便于垂直插装或板上直接焊接,节省 PCB 面积。由于模块功率密度较高,设计时应注意:
适用于工业控制、仪表采集、通信设备、传感器隔离、地环路抑制与信号链隔离等场合。设计建议包括:
选择 B0505S-2WR3 时,请确认:系统需要 5V 输入并输出隔离 5V、最大负载不超过 400mA、对隔离等级要求在 1.5kV 左右。若需更高输出功率、更大电流或更高隔离电压,请参考 YLPTEC 的其他系列产品。最终设计前建议获取并阅读厂家完整数据手册,确认短路保护恢复模式、工作温度范围及安全/寿命测试报告,以确保在具体应用中的可靠性与合规性。

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.
