YLPTEC B1205LS-1WR3 1W降压型电源模块概述

YLPTEC(易川)B1205LS-1WR3是一款针对小功率隔离降压场景优化的电源模块,核心功能为将10.8~13.2V直流电压高效转换为5V/200mA稳定输出,具备宽温适应、电气隔离、短路保护等特性,适用于工业传感器、物联网终端、嵌入式控制等对体积、可靠性要求较高的场景。

一、核心功能与典型应用

该模块聚焦12V系统转5V小功率隔离供电,覆盖三大领域的典型需求:

  • 工业场景:为温湿度传感器、压力变送器、PLC扩展模块供电,适配车间12V直流电源,1.5kV隔离可阻断前端电网干扰,保护敏感的模拟/数字电路;
  • 物联网终端:如户外环境监测节点、智能门禁控制器,-40~+85℃宽温范围可适应北方冬季低温(-30℃左右)或南方夏季高温(40℃以上);
  • 嵌入式系统:小型单片机开发板、LoRa/蓝牙通信模块的供电,小体积SIP封装可嵌入紧凑的设备外壳内。

二、关键电气参数与实际价值

模块参数围绕“稳定、高效、带载”设计,具体解析如下:

  1. 输入输出匹配:输入10.8~13.2V(覆盖12V电源±10%波动,工业现场常见范围),输出5V/200mA(1W额定功率),满足STM32L等低功耗芯片供电需求;
  2. 转换效率与发热:88%效率在1W模块中属较高水平,减少自身发热,无需额外散热片即可稳定工作;
  3. 纹波与噪声控制:30mVp-p输出纹波远低于多数数字电路抗干扰阈值(100mV以内),避免干扰ADC采样、通信信号;
  4. 带载能力:最大容性负载2400uF,兼容多组滤波电容并联,启动无电压跌落,负载切换稳定;
  5. 开关频率:100kHz避开EMC敏感频段(如AM广播),电磁兼容性较好,无需额外滤波。

三、封装与物理特性

采用SIP单列直插封装,尺寸19.5mm×6mm×10mm,优势明显:

  • 小体积:约1.17cm³,可嵌入直径20mm的传感器外壳,节省空间;
  • 安装便捷:直插引脚可直接焊接PCB,无需复杂贴片工艺,适合批量或手工生产;
  • 集成化设计:内部集成电感、电容等元件,无需外部额外器件,简化电路。

四、可靠性与安全保护

针对工业级要求设计,核心特性包括:

  1. 宽温适应:-40~+85℃工作范围,通过高低温循环测试,极端环境下长期稳定;
  2. 电气隔离:1.5kVrms隔离电压(符合UL60950标准),隔离前端高压干扰,保护负载;
  3. 短路保护:内置短路保护,输出短路时自动切断,故障排除后恢复,避免模块损坏;
  4. 低功耗设计:轻载/待机功耗低,适合电池供电的便携设备或长期运行终端。

五、应用优势总结

该模块优势可概括为“小、稳、全、适”:

  • 小:SIP小封装,适配紧凑空间;
  • 稳:低纹波、宽输入、稳定输出,满足敏感电路;
  • 全:宽温、隔离、短路保护,覆盖工业级可靠性;
  • 适:12V转5V场景优化,适配多数物联网、工业终端。

B1205LS-1WR3可作为工业传感器、物联网节点的首选隔离降压电源,无需额外设计即可快速集成,降低开发成本与周期。

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
