YLPTEC QA243C-2005R3 电源模块产品概述
一、产品定位与核心身份
YLPTEC（易川）QA243C-2005R3是一款专为24V系统设计的双路隔离电源模块，针对工业、车载等场景对「正负双路输出」的需求优化，以紧凑SIP封装、高隔离特性、宽温适应能力，成为中低端功率双路供电场景的实用方案。
二、关键参数与性能优势
1. 宽输入与精准双路输出
输入电压覆盖21.6V~26.4V，完美适配工业24V直流电源的典型波动（如电池欠压至满电区间），无需额外稳压电路即可稳定工作；输出端提供两路独立输出：
- 负电压：-5V/90mA
- 正电压：20V/90mA
两路电流能力匹配，可直接满足运算放大器、传感器接口等同时需要正负电压供电的电路需求。
2. 高效转换与低噪声控制
转换效率达81%，减少模块自身功耗与散热，降低系统热设计压力；输出纹波噪声严格控制在100mVp-p，符合精密传感器、模拟电路等对噪声敏感场景的供电要求，避免纹波干扰信号精度。
3. 高隔离与高频设计
具备5kVrms AC隔离电压，有效隔离前后级电路的电气干扰，保障医疗、通信等敏感设备的安全与稳定；开关频率为200kHz，高频设计缩小了内部磁性元件体积，是实现小封装的核心支撑。
三、封装与物理特性
模块采用SIP-5直插封装，安装便捷，适合传统PCB布局；物理尺寸仅19.5mm（长）×9.8mm（宽）×12.5mm（高），体积紧凑，可节省设备内部空间，适配小型化、高密度的工业/车载设备。
同时支持最大2200uF容性负载，无需额外限制后端电容容量，可直接驱动大电容电路，简化系统设计。
四、安全特性与可靠性
1. 短路保护功能
内置短路保护机制，当输出端发生短路故障时，模块自动切断输出，避免自身损坏或故障扩散，提升系统整体可靠性。
2. 宽温工作范围
工作温度覆盖**-40℃~+105℃**，满足工业环境的极端温度需求（如户外控制柜、车载低温启动场景），无需额外散热或保温措施，适应恶劣工况。
五、典型应用场景
QA243C-2005R3的参数特性使其适配多类场景：
- 工业控制：PLC模块、传感器接口电路（需正负电压供电）；
- 车载电子：24V车载终端、车载传感器（宽温+隔离适配车载环境）；
- 通信设备：小型基站模块、光纤收发器（高隔离抗干扰）；
- 医疗仪器：低功率医疗设备（高隔离保障安全）。
六、总结与价值点
QA243C-2005R3的核心价值体现在：
- 精准匹配24V系统的宽输入波动；
- 双路正负输出满足混合信号电路需求；
- 5kV隔离+短路保护保障系统安全；
- 宽温+小封装适配工业/车载等恶劣紧凑场景。
其稳定可靠的性能与实用设计，是中低端功率双路供电需求的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
