YLPTEC QA123C-1803R3 模块电源产品概述

一、核心电气参数解析

YLPTEC QA123C-1803R3是一款针对12V系统设计的双路隔离式DC-DC模块,核心参数适配工业、车载等场景需求:

  • 输入适配性:10.8V~13.2V输入范围,与12V铅酸电池、车载12V电源、工业12V直流总线完全匹配,无需额外稳压电路即可直接接入;
  • 双路输出特性:两路独立输出——18V/100mA(正输出)、-3V/-100mA(负输出),电流能力均衡,可同时为需要正负电源的电路供电;
  • 隔离安全:5kV AC(有效值)隔离电压,满足工业级安全标准,有效阻断前后级共地干扰,保护敏感电路;
  • 能效与噪声:转换效率达87%,降低自身功耗与发热;输出纹波噪声≤100mVp-p,适配模拟信号调理等低噪声需求;
  • 待机与负载:空载输入电流仅8mA,低待机功耗适合电池供电场景;最大容性负载1000uF,兼容大容量滤波电容,稳定输出;
  • 工作频率:200kHz开关频率,兼顾效率与电磁兼容性(EMC),减少滤波元件体积。

二、关键特性与应用优势

  1. 双路正负电源集成:无需额外搭建负电源电路(如电荷泵),直接输出-3V,简化电路设计,节省PCB空间;
  2. 高隔离防护:5kV AC隔离电压可隔离高压差、防止接地环路干扰,适用于医疗、工业等对隔离要求严格的场景;
  3. 短路保护功能:输出短路时自动启动保护,故障排除后自行恢复,避免模块损坏,提升系统可靠性;
  4. 宽温工作能力:-40℃~+105℃的工作温度范围,覆盖户外控制柜、车载低温/高温环境,无需额外散热设计;
  5. 小尺寸封装:SIP-5直插封装,尺寸仅19.5mm×9.8mm×12.5mm,适合空间受限的小型设备(如传感器模块、车载控制器);
  6. 低噪声输出:100mVp-p纹波噪声,可直接为运算放大器、压力传感器等敏感模拟电路供电,无需额外滤波。

三、典型应用场景

QA123C-1803R3的参数特性适配多类小功率应用:

  • 工业传感器调理:为压力、流量传感器的差分放大电路供电,隔离干扰确保信号精度;
  • 车载电子模块:适配12V车载电源,为胎压监测、小型控制器等辅助单元供电;
  • 医疗低功率单元:为监护仪辅助监测电路、输液泵控制模块供电,满足隔离安全要求;
  • 通信基站附属设备:为基站内小功率信号处理、环境监测模块供电;
  • 消费电子扩展:为小型音频设备、手持测试仪器的信号调理电路供电。

四、封装与安装说明

该模块采用SIP-5直插封装,引脚布局清晰,可直接焊接于PCB板,无需额外固定件;紧凑尺寸可与其他元件紧凑布局,12.5mm高度适配普通1.6mm厚PCB,不影响周边元件安装。

五、可靠性与环境适应性

QA123C-1803R3通过宽温测试、短路保护测试、隔离耐压测试,满足工业级可靠性:

  • 宽温范围覆盖-40℃(低温启动)至+105℃(高温持续工作),适应极端环境;
  • 短路保护应对接线错误、负载故障等意外情况,提升系统抗故障能力;
  • 5kV AC隔离电压符合IEC 60950安全标准,适用于医疗、工业等隔离要求场景。

该模块以高集成度、宽适配性、强可靠性,成为12V系统中小功率正负电源需求的优选方案。

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
