QA151M 产品概述

一、产品简介

QA151M 系列是 YLPTEC(易川)推出的小型隔离直流-直流转换器,针对工业通信、仪表、模块化电源及系统隔离场合设计。该器件提供高效率、低空载功耗与自动故障恢复保护,封装为 SIP-5 小体积塑料外壳,便于电路板密集布置和批量组装。

二、主要规格

  • 输入电压:13.5V ~ 16.5V(典型 15V 输入工况)
  • 输出通道:双路输出(常见配置 -5V 与 +15V,总输出功率 2W);另有单输出版本资料列出(详见型号表)
  • 输出电压/电流:-5V/15V,各通道最大输出电流 100mA(总功率上限 2W)
  • 转换效率:典型 80%,高可达 84%(视输出负载与输入电压而定)
  • 隔离强度:3.5kVrms(资料中亦出现 1500VDC 值,请依据具体型号与认证文件最终确认)
  • 开关频率:约 83kHz
  • 纹波噪声:典型 30mVp-p(20MHz 带宽),在不同工况下可达 80–120mVp-p
  • 最大容性负载:220µF
  • 静态消耗:静态电流约 15mA(无载功耗厂方典型值 0.025W,视测量条件有所差异)
  • 体积:19.5 × 9.8 × 12.5 mm(L×W×H)
  • 工作温度:-40℃ ~ +85℃(另有资料标注最高可达 +105℃,请按具体型号数据表为准)
  • 可靠性:MTBF ≥ 3,500,000 小时(典型值)

三、功能特性

  • 恒压输出、稳压性能良好,适合对供电稳定性要求高的模拟/数字电路
  • 隔离输出提供信号与地的电气隔离,改善共模干扰与安全性
  • 短路保护并支持自动恢复:输出短路或过载时进入保护,再移除故障后自动恢复工作
  • 低空载功耗与高转换效率利于系统散热与能耗控制
  • 小型 SIP-5 封装,符合常用国际引脚排列,便于替换与基板设计

四、机械与环境注意事项

  • 封装为塑料 SIP-5,建议在通风良好或有适度散热措施的环境中长期使用
  • 最大容性负载 220µF,超大电容可能导致启动问题或稳定性下降,应根据数据表选择合适的输出滤波
  • 若需要长距离隔离或更高工频抗压,应核对所需的隔离电压等级与实际认证(3.5kVrms 与 1500VDC 的表述需与供应商确认)

五、应用场景与选型建议

  • 适合便携/嵌入式工业设备、传感器接口、电流环/隔离放大器、现场总线隔离电源等需要小功率隔离电源的场合
  • 选型时关注:输入总线稳定性、总功率预算、输出电容及纹波要求、工作温度范围与隔离认证要求
  • 若系统对输出纹波噪声敏感,可在输入/输出端增加合适的滤波/旁路电容与屏蔽措施,或选择标注更低噪声的型号

六、使用要点

  • 上电顺序:遵循系统上电规范,避免在大负载或短路情况下频繁循环上电
  • 布局与走线:输入地与输出地须分别处理,隔离边界走线留空,输出端滤波元件靠近器件引脚布局
  • 热管理:在高 ambient 或满载工况下注意散热,避免长期工作在额定温度极限附近以延长寿命

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
