B2405S-2WR3 产品概述 — YLPTEC(易川)

一、产品简介

B2405S-2WR3 是易川(YLPTEC)推出的一款降压型单通道直流变换器,额定输出功率 2W,输入电压范围 21.6V~26.4V,固定输出 5V/400mA。模块采用 SIP 封装(19.5×7×10mm),体积小、效率高,专为工业级、车载及通信设备等受限空间和高可靠性场合设计。

二、核心性能参数

  • 功能类型:降压型(单通道)
  • 输入电压:21.6V ~ 26.4V
  • 输出电压:5V
  • 输出电流(最大):400mA
  • 输出功率:2W
  • 转换效率:典型 88%
  • 开关频率:100kHz
  • 隔离电压:1.5kVrms
  • 最大容性负载:2400µF
  • 纹波噪声:50mVp-p
  • 空载输入电流:1mA
  • 特性:内置短路保护、低功耗
  • 工作温度:-40℃ ~ +85℃
  • 封装尺寸:SIP,19.5×7×10mm

三、主要特点与优势

  • 高效率:典型 88% 的转换效率,有助于降低发热并提高系统整体能效。
  • 宽温工作:适应 -40℃ 至 +85℃ 的工业级温度范围,适合严苛环境。
  • 高隔离强度:1.5kVrms 隔离电压,增强输入与输出之间的安全隔离能力,利于系统抗干扰与安全设计。
  • 保护功能:内置短路保护,提高系统稳定性与可靠性。
  • 低静态功耗:空载输入电流仅 1mA,便于节能设计和待机应用。

四、典型应用场景

  • 工业控制与自动化设备电源模块
  • 通信设备、基站及接口电源
  • 仪器仪表、数据采集模块
  • 需要隔离且空间受限的嵌入式系统

五、设计与使用建议

  • 输出端需并联低等效串联电阻(ESR)的电解或固态电容,注意最大容性负载 2400µF,以免启动或瞬态时出现不稳定。
  • 虽具有短路保护,但建议在系统层面添加熔断或限流措施以增强安全性。
  • 尽量在模块周围留出散热空间,避免长期满载在高温环境中工作,如有必要可采用小型散热片或强制对流散热。
  • 输入侧应加适当滤波与浪涌抑制,特别在电源线可能有较大干扰或瞬态的场合。

六、机械与封装

  • SIP 封装,外形尺寸 19.5 × 7 × 10 mm,便于通过孔及插针安装于标准 PCB。
  • 引脚排列与安装孔位请参照样品或数据手册进行 PCB 布局,推荐走线留有绝缘及爬电距离以配合 1.5kVrms 隔离要求。

总结:B2405S-2WR3 兼顾高效率、宽温与高隔离能力,适合对体积、能效与可靠性有要求的工业与通信电源设计。在实际应用中,按数据手册的最大容性负载、散热及保护建议布置,可获得长期稳定的工作表现。如需原理图示例或 PCB 布局建议,可提供更多设计细节以便给出针对性指导。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
