B1212S-1WR3 1W隔离DC-DC电源模块产品概述

一、产品定位与核心优势

B1212S-1WR3是海凌科(HI-LINK)针对小功率隔离供电场景推出的单通道DC-DC电源模块,核心聚焦“紧凑封装+高可靠性+宽适配性”三大特点。该模块专为空间受限的嵌入式系统设计,集成短路保护、宽温工作等实用特性,可替代传统分立电源方案,覆盖工业控制、物联网、通信等多领域应用,是1W级小负载设备的高效隔离供电选择。

二、关键电气参数详解

2.1 输入输出特性

模块支持10.8V~13.2V宽输入电压范围(适配12V系统的电源波动),输出稳定12V直流电压,最大输出电流84mA(1W功率下满足小负载需求)。转换效率达80%,在1W功率等级下发热低,无需额外散热设计,简化系统布局。

2.2 隔离与噪声性能

具备1.5kVrms高隔离电压,可有效阻断输入输出电路的共模干扰,提升系统抗干扰能力;输出纹波噪声低至30mVp-p,满足模拟电路(如传感器信号采集)对电源噪声的严苛要求,避免噪声干扰信号精度。

2.3 负载与稳定性

最大容性负载达560uF,支持带容性负载启动,适配后端电容滤波电路;开关频率100kHz,工作状态稳定,无明显电磁干扰(EMI)问题,符合多数工业设备的EMC规范。

三、物理特性与封装设计

采用SIP(单列直插)封装,尺寸仅11.5mm(长)×6mm(宽)×10mm(高),体积紧凑至传统电源方案的1/3以下,可直接焊接于PCB板,节省系统内部空间。封装结构耐振动、抗冲击,适合户外或工业现场的复杂环境。

四、典型应用场景

4.1 工业控制领域

用于PLC模块、传感器节点的隔离供电:1.5kV隔离电压可防止现场强电磁干扰窜入敏感电路;-40℃~+85℃宽温范围适配工业现场高低温环境,无需额外温控设计。

4.2 物联网终端

针对低功耗IoT设备(如智能传感器、无线网关):小体积可嵌入设备内部,短路保护功能提升终端可靠性,避免因输出短路导致整个系统故障。

4.3 通信设备

作为4G/5G模组的辅助隔离电源:低噪声特性保障信号传输稳定性,1W功率满足模组待机与工作状态的供电需求,适配通信设备的紧凑布局。

4.4 汽车电子边缘应用

宽温范围(-40~85℃)符合汽车级边缘设备的温度要求,12V输入输出适配车载12V电源系统,可用于车载传感器、小型控制器的隔离供电。

五、可靠性与安全特性

  1. 短路保护:输出端短路时自动进入限流保护,故障排除后自行恢复,避免模块或负载损坏;
  2. 宽温可靠性:-40℃~+85℃工业级温度范围,通过高低温循环测试,适配极端环境;
  3. 高隔离安全:1.5kVrms隔离电压符合电气安全规范,可有效隔离高低压电路;
  4. 长寿命设计:采用高品质元器件,平均无故障时间(MTBF)达10万小时以上,降低系统维护成本。

B1212S-1WR3凭借紧凑封装、高隔离、宽温适配等特性,成为小功率隔离供电场景的高性价比选择,可满足多数工业与消费电子设备的核心供电需求。

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
