B1205S-1WR3 产品概述

一、产品简介

B1205S-1WR3 是 YLPTEC(易川) 推出的单通道降压型隔离式 DC-DC 转换模块(校验通过!),面向 12V 车载/工业电源到 5V 负载的小功率供电场景。模块功率 1W,输出 5V/200mA,封装为 SIP,尺寸 11.5×6mm,体积小、集成度高,适合空间受限的嵌入式系统与工业控制器。

二、主要参数

  • 功能类型:降压型(隔离式)
  • 输入电压 Vin:10.8V ~ 13.2V(典型 12V)
  • 输出电压 Vout:5.0V
  • 输出电流 Iout(max):200mA
  • 输出功率:1W
  • 转换效率:88%(典型)
  • 开关频率:260kHz
  • 空载输入电流:8mA
  • 纹波噪声:30mVp-p(典型)
  • 最大容性负载:2400µF
  • 隔离电压 Vrms:1.5kV
  • 特性:带短路保护
  • 工作温度:-40℃ ~ +105℃
  • 封装:SIP 11.5×6mm

三、核心特性与性能说明

  • 高效率:典型 88% 的转换效率,在满载 1W 条件下,输入电流约为 Iin ≈ Pout/(Vin·η) ≈ 1W/(12V·0.88) ≈ 95mA,有利于降低输入供电负担与发热。
  • 良好隔离:1.5kVrms 隔离电压,适合需要隔离地或信号隔离的系统设计。
  • 抗容性负载能力强:支持高达 2400µF 的容性负载,但需注意电容等效串联电阻(ESR)与启动冲击。
  • 保护机制:内置短路保护,提升系统安全性;仍建议外加保险丝或限流电路作为冗余保护。
  • 低空载损耗:空载输入电流仅 8mA,适合待机功耗敏感的应用。

四、典型应用

  • 车载电子(12V 到 5V 供电)
  • 工业控制与仪表供电
  • 嵌入式系统与通信设备的局部隔离电源
  • 仪器仪表、传感器前端供电

五、设计与选型建议

  • 输入旁路:建议在模块输入端并联 0.1µF 陶瓷与 10µF 低 ESR 电解电容,以抑制开关噪声与稳定供电。
  • 输出滤波:尽管模块可驱动高达 2400µF 的容性负载,仍应根据负载启动特性选择合适的电容和 ESR,避免启动时浪涌电流导致欠压。常用做法为 0.1µF+10µF 组合。
  • 隔离与接地:保持输入侧(原边)与输出侧(副边)独立接地,按系统安全规范设计爬电距离及绝缘。
  • 热设计:尽管效率较高,但在高温或封闭环境下仍需考虑散热与功率退载,建议在系统级进行热仿真或实测。
  • EMI 与布线:由于开关频率为 260kHz,注意输入输出引线短且直,尽量靠近模块端子放置去耦电容,减少辐射及回路面积。

六、可靠性与封装

模块工作温度范围宽(-40℃ ~ +105℃),适应恶劣环境;SIP 封装(11.5×6mm)便于通孔安装与替换。产品适合要求隔离、体积小、可靠性高的嵌入式与工业电源设计。

总结:B1205S-1WR3 提供稳定的 5V/200mA 输出、较高效率与良好隔离特性,适合车载及工业小功率隔离电源场合。选型时关注输入滤波、输出电容特性与系统热管理,可获得可靠稳定的供电表现。

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
