B2405S-1WR3 是 YLPTEC(易川)推出的一款高密度、单路隔离降压型直流-直流电源模块,专为24V类母线系统向低压逻辑或模拟电路提供稳定隔离电源而设计。模块采用 SIP 插件封装(尺寸 11.6 × 6 × 10.16 mm),功率 1W,输出 5V/200mA,兼顾体积、效率与可靠性,适用于工业控制、仪表、通信设备等对隔离和低噪声有要求的场合。
在满载(1W 输出)且效率 88% 时,输入功率约为 1W / 0.88 ≈ 1.136W;以典型 24V 输入计算,输入电流约为 1.136W / 24V ≈ 47 mA。模块自身空载输入电流为 8 mA,在待机或低负载工况下整体系统功耗较低。输出纹波典型 30 mV p-p,满足大多数数字电路和模拟前端对低噪声电源的需求。
模块内置短路保护,有助于在输出短路或过载时保护模块本体和下游电路。额定隔离电压 1.5 kV RMS 可提供合理的安全隔离,适用于信号隔离、地环路消除及安全隔离场景。长期工作温度范围宽(-40~+105 ℃),适合工业级应用环境。
SIP 插件式封装便于直接插入 PCB 并进行波峰或手工焊接,占板面积小、垂直高度约 10.16 mm,适合空间受限的控制板或信号隔离模块。最大可驱动 2400 μF 的容性负载,便于在输出端并联较大容量滤波电容以降低低频纹波与瞬态响应。
B2405S-1WR3 以紧凑的 SIP 插件封装、高达 1.5 kV 的隔离能力、较高的转换效率(约 88%)和工业级工作温度覆盖,为 24V 母线向 5V 隔离供电提供了一种体积小、性能稳定的解决方案。其短路保护、较低的空载电流和对容性负载的良好支持,使其在工业控制、仪表与通信等需要隔离与低噪声电源的场合具有较高的适用性。若需进一步的引脚信息、典型接线或样品测试数据,可联系供应商或查阅完整规格书。

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.
