B1212S-2WR3 是 YLPTEC(易川)出品的一款单通道隔离型 DC-DC 转换器,额定输出功率 2W,输入标称 12V(工作电压范围 10.8V~13.2V),输出 12V,最大输出电流 166mA。模块为插件封装,外形尺寸小巧(19.5 × 7 × 10 mm),适合对体积、隔离和低功耗有要求的嵌入式与工业应用。描述:校验通过!
在满载且效率为 86% 的情况下,模块自身功耗约 0.3–0.4W,通常无需额外散热片,但在高温或密集封装场景下建议预留空气对流空间或在 PCB 上做散热过孔。工作温度范围 -40℃~+85℃,适合大多数工业级应用。长期可靠性与寿命会受环境温湿度、输入纹波与过压冲击影响,建议在设计阶段做好滤波与保护电路。
总结:B1212S-2WR3 是一款体积小、效率高、具隔离与短路保护的 2W 单路 DC-DC 模块,适合用于要求隔离、低功耗及稳定供电的小型嵌入式和工业系统。

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.
