B2405S-1WR2 产品概述

一、概述

B2405S-1WR2 是 YLPTEC(易川)推出的一款降压型隔离直流-直流转换器,单通道输出,面向工业、通信及嵌入式系统中的 24V 供电到 5V 负载的隔离降压需求。器件具有坚固的工作温度范围与隔离能力,适用于要求体积小、可靠性高的场景。

二、主要电气参数

  • 功能类型:降压型(隔离型 DC-DC)
  • 输入电压范围:21.6V ~ 26.4V(典型工况针对 24V 系统)
  • 输出电压:5V
  • 输出电流(最大):42mA
  • 标称输出功率:1W(注:按 5V×42mA 实际输出约 210mW,请在设计时确认额定与持续输出限制)
  • 转换效率:80%(典型)
  • 空载输入电流:8mA
  • 开关频率:260kHz
  • 输出纹波噪声:30mVp-p(典型)
  • 最大容性负载:220µF
  • 隔离电压(Vrms):1.5kV

三、关键特性与保护

  • 内置短路保护:提高系统安全性,防止输出短路导致器件及系统损坏。
  • 中等效率(约 80%):在 24V 输入下用于低功率负载时具有合理的功耗与热耗平衡。
  • 低空载输入电流(8mA):便于降低待机功耗和轻载工况下的能耗。

四、热性能与环境适应性

  • 工作温度范围:-40°C ~ +105°C,适应工业级温度环境。
  • 由于器件体积小且为插件封装,散热主要依赖于 PCB 布局与安装方式,建议在高温或靠近散热源的场合进行热仿真或留有散热空间,并在满载或接近额定条件下注意降额使用。

五、封装与机械尺寸

  • 封装方式:插件(Through-hole)
  • 外形尺寸:长度 11.6mm × 宽度 6.0mm × 高度 10.16mm,便于在空间受限的板上布局与牢固安装。

六、典型应用与使用建议

  • 典型应用:24V 工业控制系统、通信设备的辅助电源、传感器、电源模块隔离部分、仪表与数据采集前端供电等。
  • 使用建议:
    • 在输入侧增加适当的滤波/保护(如熔断器、TVS)以应对瞬态浪涌。
    • 输出侧按需并联低等效串联电阻(ESR)电容,注意最大容性负载 220µF,避免过大电容引起启动冲击或振荡。
    • 布局时将高频开关回路尽量缩短,信号地与功率地合理分区,保证纹波与发射噪声控制在可接受范围。
    • 高温环境下考虑降额运行或加装散热措施。

七、注意事项与校核建议

  • 参数校核:给定资料中同时存在“标称输出功率 1W”与“输出电流最大 42mA(对应约 210mW)”两项,应在设计前与供应商或器件手册确认实际额定输出能力与工作限制,避免过载。
  • 隔离要求:1.5kVrms 隔离适用于多数工业低压隔离场合,但在安全或更高隔离等级需求的系统中需评估是否满足规格认证与安规要求。
  • 测试与验证:在最终系统中进行纹波、负载瞬变、短路恢复与温升测试,验证在实际工况下的稳定性与可靠性。

总结:B2405S-1WR2 以其紧凑封装、工业级温度与隔离能力,适用于 24V 电源向小功率 5V 负载供电的隔离场景。在使用前请核实额定输出功率与持续输出电流的对应关系,并根据系统散热与滤波要求进行适当设计。

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
