WRB2412S-3WR2 是 YLPTEC(易川) 推出的一款单通道隔离型 DC-DC 转换器,额定输出功率 3W,输入电压范围 18V ~ 36V,输出 12V/250mA。模块采用 SIP-7 小体积封装(22mm × 9.5mm × 12mm),具有 1.5kVrms 隔离能力与短路保护功能,适合空间受限且需高可靠隔离电源的工业与通信场景。
在满载(3W)与典型效率 80% 情况下,模块自身功耗约为 0.75W,输入电流随输入电压变化:在 Vin=18V 时 Iin≈208mA,在 Vin=36V 时 Iin≈104mA。因此在高温与高输入电压条件下需注意热量散出,建议保持良好自然对流或适当散热板以保证长期可靠工作。输出允许的最大容性负载为 680µF,超大电容可能影响稳定性和启动行为,建议使用低 ESR 的陶瓷/铝电解组合滤波。

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.
