WRB2405S-3WR2 产品概述
一、概述
WRB2405S-3WR2 是 YLPTEC(易川) 推出的一款降压型隔离开关电源模块，单通道输出，额定输出功率 3W。模块输入电压宽范围为 18V 至 36V，固定输出 5V，最大输出电流 600mA。该产品体积小巧（22 × 9.5 × 12 mm，SIP 封装），适用于空间受限且需隔离保护的工业及通信类设备。
二、主要电气参数
- 输入电压 Vin：18V ~ 36V
- 输出电压 Vout：5V（固定）
- 输出电流 Iout(max)：600mA
- 输出功率：3W
- 转换效率：典型 78%
- 开关频率：300kHz
- 纹波噪声：100mVp-p（典型）
- 最大容性负载：2200µF
- 隔离电压 Vrms：1.5kV
三、保护与可靠性
模块具备短路保护功能，可在异常工作条件下提供基本的输出保护，提升系统可靠性。工作温度范围宽（-40℃ ~ +85℃），适应工业级环境温度要求。在正确的散热条件下，可长期稳定运行。
四、机械与封装
采用 SIP 直插封装，封装尺寸 22.0 × 9.5 × 12.0 mm，便于插入式或焊接安装。小体积设计利于在机箱或模块化板卡中节省空间。
五、应用场景
适用于：通信基站模块、工业控制设备、仪器仪表、安防设备、嵌入式系统等需要隔离且输入18~36V电源的场合，尤其对体积、散热与隔离要求较高的应用场景更为适合。
六、使用建议
- 输入侧建议并联低等效串联电阻（ESR）电容以抑制输入瞬态；输出侧在靠近输出端放置低 ESR 电容以降低纹波与改善瞬态响应，但请勿超过最大容性负载 2200µF。
- 为保证效率与寿命，应在模块周围留有通风空间或在 PCB 上配合热铜箔散热，避免长时间在高温环境下运行。
- 在系统设计时，应考虑隔离要求与接地策略，确保隔离端正确接线与安全间隙满足系统规范。
WRB2405S-3WR2 以其小尺寸、高隔离和稳定的输出特性，适合用于对可靠性与空间有较高要求的中低功率隔离降压场合。若需更详细的引脚定义、典型应用电路或电气表格，请提供进一步需求以便补充。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
