B1205S-1W是YLPTEC(易川)推出的隔离式降压型DC-DC电源模块,专为小功率、需电气隔离的直流电压转换场景设计。其核心功能是将10.8V~13.2V的宽范围输入电压,高效转换为稳定的5V直流输出,满足1W以内的负载功率需求,同时提供1.5kVrms的电气隔离,保障前后级电路安全。该模块集成度高,无需额外外围元件即可稳定工作,适合对体积、可靠性要求较高的嵌入式系统。
采用300kHz固定开关频率,频率稳定且处于电磁干扰(EMI)相对较低的频段,可简化系统EMI滤波设计,降低对周边电路的干扰。
该模块采用SIP单列直插式封装,尺寸为11.68mm(长)×10.15mm(宽)×6mm(高),体积紧凑(标称尺寸约11.5×6mm),适合在空间受限的嵌入式设备、小型仪器仪表中安装。SIP封装便于插件焊接,无需复杂的贴片工艺,降低了生产难度与成本,同时散热面积合理,可满足1W功率下的散热需求。
支持**-40℃~+85℃**的极端温度环境,可适应工业现场(如户外设备、车间控制柜)、车载辅助电路等场景,无需额外散热措施即可稳定运行。
最大容性负载达200uF,可兼容后端较大容量的滤波电容,进一步降低输出纹波,提升负载瞬态响应能力,适合对电源瞬态性能要求较高的场景(如数据采集系统)。
除短路保护外,模块内置过流、过温防护(隐含特性,可通过实际测试验证),进一步提升了系统可靠性。
B1205S-1W因体积小、效率高、隔离安全,广泛适用于以下场景:
B1205S-1W凭借紧凑体积、高隔离性能与稳定输出,成为小功率隔离降压场景的优选方案,可快速适配各类嵌入式系统的供电需求。

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.
