B1505S-1WR3 是 YLPTEC(易川)推出的一款小体积、高效率的微功率隔离式 DC/DC 模块。模块为定电压输入、隔离非稳压的单路输出设计,额定输出功率 1W,适合在板上电源系统中生成与主电源隔离的低功率电压源。模块体积小(11.5 × 6 × 10 mm,SIP 封装),方便在空间受限的场合进行并排布置或嵌入式系统应用。
模块采用 SIP 封装,尺寸 11.5 × 6 × 10 mm,非常适合插装或波峰/手工焊接在 PCB 上。建议在设计 PCB 时为模块留出足够的焊盘面积和周边过孔,以利于散热和机械固定。布线时输入输出走向分开,避免高频回流与敏感信号线近距平行。
B1505S-1WR3 具备短路保护和过热保护,并支持自动故障恢复,能够在异常解除后自动恢复工作状态,减少人工干预。隔离电压 1.5 kV 可满足多数工业与通信设备的隔离要求。推荐在系统设计中配合合适的输入保险丝与浪涌保护元件,以进一步提高整机可靠性。
总结:B1505S-1WR3 是一款体积小、效率高、隔离性能可靠的微功率 DC/DC 模块,适合用于对隔离、体积和功耗有严格要求但对输出稳压精度要求不高的板上电源场合。根据具体应用场景,可通过外部滤波与二次稳压措施,满足更高的输出质量需求。

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.
