WRB2403S-3WR2 产品概述
一、产品简介
WRB2403S-3WR2 是 YLPTEC（易川）推出的一款超小型隔离型 DC-DC 变换器，采用窄体 SIP-7 塑料引脚封装，提供单路 3.3V 输出并能在 18V～36V 宽输入范围内稳定工作（2:1 输入比）。该模块额定输出功率 3W，具有较高的转换效率和完整的保护功能，适合通信设备、仪器仪表与各类工业电子系统中对体积、成本与隔离性能有要求的场合。
二、主要规格参数
- 输入电压：18V ～ 36V（2:1 输入范围）
- 输出通道数：1
- 输出电压：3.3V
- 输出电流（最大）：600mA
- 输出功率：3W
- 典型转换效率：约 71%
- 最大容性负载：2200µF
- 开关频率：300kHz
- 纹波噪声：100mVpp（典型）
- 隔离电压：1.5kV（常规等级），可提供 3.0kV 等级（依据具体型号）
- 环境温度范围：-40℃ ～ +85℃
- 机械尺寸：22mm × 9.5mm × 12mm（封装：SIP-7）
三、保护与控制特性
- 短路保护：具有自恢复能力的短路保护机制，出现输出短路或过载时自动限制输出并在故障解除后恢复工作。
- 欠压保护与过流保护：内置欠压锁定与过流检测，提升系统安全性与可靠性。
- 远程遥控功能：支持外部使能/禁能控制（远程开关），便于系统集成与电源管理。
四、热管理与性能建议
- 在额定条件下，按 71% 效率估算，满载时模块损耗约 1.2W（P_loss ≈ Pout(1/η - 1)），需考虑散热途径与环境温度对输出能力的影响。
- 推荐保持模块附近良好通风与尽量减少热源叠加；在高温或连续满载工况下建议适当降额使用。
- 输出滤波：模块可驱动高达 2200µF 的容性负载，但为控制启动与稳定性能，应根据系统要求选择低 ESR 输出电容并在输入侧配合适当去耦电容。
五、典型应用场景
- 通信设备：基站远端、接口电源与隔离供电模块。
- 仪器仪表：数据采集、隔离信号链供电。
- 工业控制：传感器供电、现场总线隔离电源及嵌入式控制单元。
- 其他需要体积小、隔离强且成本敏感的低功率应用。
六、设计与选型注意事项
- 输入滤波与浪涌抑制：工业环境下可能存在电源瞬态，建议在输入端加装合适的滤波与浪涌抑制元件以保护模块。
- 隔离等级选择：根据系统安全规范（如需要更高隔离电压或耐压测试要求），选择 1.5kV 或 3kV 等级型号。
- PCB 布局：尽量缩短高频回路环路、保证输入与输出接地良好并合理布置散热通道。
- 测试与认证：在关键应用中，建议对模块在目标系统中进行温升、EMC 与长期可靠性测试。
WRB2403S-3WR2 以其超小体积、完整保护和宽输入范围，提供了在苛刻工业与通信环境中实现隔离供电的经济高效方案。若需更详细的电气参数曲线、典型应用电路或安装注意事项，可提供相关数据手册以便进一步评估与设计。

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.
