YLPTEC B0503S-1WR2 1W隔离降压电源模块产品概述

一、产品定位与核心功能

YLPTEC B0503S-1WR2是一款小功率隔离降压电源模块,专为5V系统设计,核心功能是将4.5V~5.5V输入电压稳定转换为3.3V输出,同时提供1.5kVrms电气隔离。该模块针对工业级应用优化,兼顾可靠性与易用性,适合需要紧凑尺寸、隔离防护的低功耗设备供电场景,无需额外外围电路即可直接使用。

二、关键电气参数解析

1. 输入输出核心参数

  • 输入范围:4.5V~5.5V(典型值5V),适配常见USB电源、5V适配器及电池供电场景,覆盖实际应用中的电压波动;
  • 输出特性:3.3V稳定输出,最大输出电流303mA(对应1W功率,符合3.3V×303mA≈1W的实际计算),可满足多数低功耗数字电路(如MCU、传感器、通信模块)的供电需求;
  • 功率效率:转换效率达72%,在1W小功率隔离模块中表现优异,减少模块自身发热,无需额外散热片即可稳定工作。

2. 纹波与待机特性

  • 纹波噪声:控制在30mVp-p,满足一般数字电路对电源纹波的要求(通常需≤50mVp-p),无需额外滤波电容即可驱动多数负载;
  • 空载电流:仅8mA,在小功率模块中处于较低水平,适合长期待机的设备(如智能家居节点、电池供电仪器),减少待机功耗损耗。

3. 隔离与负载能力

  • 隔离电压:1.5kVrms(有效值),可有效隔离高低压侧干扰,防止高压侧故障(如静电、浪涌)影响低压负载,提升系统抗干扰性;
  • 容性负载:最大支持220uF,支持负载突变时的电流缓冲(如电机启动、传感器上电),避免输出电压波动。

三、核心特性优势

1. 安全防护设计

内置短路保护功能,当输出端意外短路时自动切断输出,故障排除后自动恢复,可有效保护模块与负载免受损坏,降低现场维护成本。

2. 宽温适应性

支持**-40℃~+105℃工业级温度范围**,可适应户外、工业现场等极端环境(如冷库、高温车间),无需降额使用,可靠性符合工业设备要求。

3. 易用性与电磁兼容性

  • 采用插件封装,无需复杂焊接工具,手工或批量生产均易操作,适合原型开发与中小批量生产;
  • 开关频率270kHz处于音频范围外,无电磁干扰(EMI)问题,无需额外屏蔽措施,可直接集成到敏感电路中。

四、封装与物理尺寸

模块采用插件式封装,物理尺寸为长11.6mm×宽6mm×高10.16mm,体积紧凑,可轻松集成到小型设备(如手持仪器、控制板、智能家居节点)中。插件引脚布局合理,焊接时不易出现虚焊,提升生产效率。

五、典型应用场景

  1. 工业控制:PLC输入输出模块、传感器接口电路(温度/压力传感器),利用隔离特性防止现场干扰影响控制信号;
  2. 通信设备:小型路由器、WiFi/Bluetooth模块的电源转换,适配5V输入与3.3V核心供电;
  3. 医疗电子:便携式监护仪、血糖检测仪等低功率医疗设备,满足电气隔离的安全要求;
  4. 消费电子:智能开关、传感器节点等智能家居设备,宽温与短路保护适合家庭环境长期稳定运行。

六、可靠性总结

YLPTEC B0503S-1WR2通过了宽温测试、短路保护测试及隔离耐压测试,可满足工业级应用的可靠性要求。其紧凑尺寸、隔离防护与低待机功耗的特点,使其成为5V转3.3V隔离供电场景的高性价比选择。

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
