B0303S-1W 隔离电源模块产品概述

一、产品定位与品牌背景

B0303S-1W是YLPTEC(易川)推出的1W单通道隔离电源模块,采用插件封装形式,专为需要小功率隔离供电的场景设计。YLPTEC作为专注于电源模块研发的品牌,其产品覆盖工业级、消费级等多个领域,该模块继承了品牌在电源可靠性与紧凑性上的设计优势,适配多种紧凑空间的设备供电需求。

二、核心电气性能参数

该模块的电气参数针对小功率隔离场景做了针对性优化,关键指标如下:

2.1 输入输出特性

  • 输入电压范围:2.97V~3.63V(对应3.3V系统的±10%波动,覆盖常见电源波动场景,无需额外稳压即可稳定工作);
  • 输出特性:稳定3.3V输出,额定功率1W,最大输出电流303mA(1W/3.3V≈303mA,满足大多数低功耗数字电路、传感器的供电需求);
  • 转换效率:72%,在1W小功率模块中表现均衡,减少自身功耗发热,提升系统能效。

2.2 隔离与保护特性

  • 隔离电压:1.5kVrms(满足基本电气隔离要求,可有效抑制共地干扰,避免不同电路模块之间的信号串扰);
  • 保护功能:内置短路保护,当输出端出现短路故障时自动切断输出,故障排除后可恢复正常工作,降低模块与负载的损坏风险。

2.3 工作条件与纹波

  • 工作温度:-40℃~+85℃(工业级宽温范围,适应极端环境温度变化,如户外设备、工业现场);
  • 开关频率:100kHz(常见开关频率,EMI辐射相对可控,无需额外复杂滤波电路);
  • 纹波噪声:60mVp-p(低纹波输出,满足数字电路、模拟传感器等对电源纯净度的要求);
  • 容性负载能力:最大200uF(可带较大输出电容,进一步稳定输出电压,适配对电压稳定性要求较高的负载)。

三、物理尺寸与封装形式

B0303S-1W采用插件封装,物理尺寸为长11.68mm×宽10.15mm×高6mm,体积小巧紧凑,可轻松集成到空间有限的设备中(如小型PLC、传感器节点、通信模块等)。插件封装形式安装便捷,无需复杂的贴片设备,适合手工焊接或批量插件生产,降低生产门槛。

四、典型应用场景

该模块因参数适配性强,可广泛应用于以下场景:

  1. 工业自动化:PLC输入输出模块、温度/压力传感器的隔离供电,抑制工业现场的电磁干扰;
  2. 消费电子:智能家居节点(如智能开关、人体传感器)、小型手持设备的隔离电源,提升设备抗干扰能力;
  3. 通信设备:低功率通信模块(如蓝牙、WiFi、LoRa节点)的隔离供电,避免通信模块与主系统的共地干扰;
  4. 小型医疗设备:小型监护仪、便携式医疗仪器的辅助供电(需注意医疗场景的隔离等级要求,该模块1.5kVrms可满足部分低风险医疗场景)。

五、产品优势总结

B0303S-1W的核心优势体现在:

  • 宽输入适应:覆盖3.3V系统±10%波动,无需额外稳压;
  • 安全隔离:1.5kVrms隔离电压,有效抑制共地干扰;
  • 宽温可靠:-40~+85℃工业级温度范围,适应恶劣环境;
  • 集成保护:短路保护功能,降低故障风险;
  • 紧凑易装:插件封装+小体积,适配各类紧凑布局场景。

该模块凭借均衡的性能与可靠的设计,成为小功率隔离供电场景的实用选择。

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
