YLPTEC B2403S-1WR3是一款专为工业控制、通信设备、传感器节点等场景打造的小功率隔离降压DC-DC转换器,核心解决24V直流电源(21.6~26.4V波动范围)向3.3V低压逻辑电路供电的问题,同时通过1.5kVrms隔离保障高低压侧电气安全,适配宽温、紧凑安装等严苛环境需求,是替代传统线性稳压+隔离方案的高性价比选择。
输入电压覆盖21.6~26.4V,精准匹配24V工业电源的**±10%常规波动范围**,无需额外稳压电路即可稳定工作,降低系统设计复杂度,避免因电源波动导致的输出异常。
隔离电压达到1.5kVrms(满足GB/T 13070-2012电气隔离标准),可有效阻断高低压侧的电气干扰:
采用SIP-4插针封装,尺寸仅11.6×6×10.16mm,比传统DIP封装模块体积缩小约30%,适合紧凑PCB布局(如PLC输入输出模块、小型传感器节点);1W功率无明显温升,无需额外散热片即可稳定工作。
工作温度范围-40℃~+105℃,覆盖工业级环境(户外控制柜、车载电子)与部分高温场景,无需降额使用,可靠性符合IEC 60068-2-1(低温)、IEC 60068-2-2(高温)等环境测试标准。
输出纹波噪声仅30mVp-p(典型值),无需额外滤波电路即可满足MCU、传感器、ADC等对纹波敏感的电路供电要求,降低系统噪声干扰。
YLPTEC B2403S-1WR3以宽输入适配、高隔离安全、小体积集成、宽温可靠为核心优势,精准匹配工业24V系统向3.3V低压电路供电的需求,可有效简化系统设计、提升设备可靠性,是工业控制、通信、传感器等领域的高性价比选择。

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.
