R-78E5.0-0.5 产品概述

一、产品简介

R-78E5.0-0.5 是 YLPTEC(易川)推出的一款降压型开关稳压模块(SIP-3P 封装),提供高度集成的 +5V 输出、最大 500mA 输出电流的小型电源解决方案。模块采用高效降压转换架构,工作电压范围覆盖中高压母线,适配常见的 12V/24V 系统,兼具低静态电流与良好的纹波特性,适用于对效率与体积有要求的工业与嵌入式应用。校验通过,产品可靠性与参数一致性满足量产需求。

二、主要性能参数

  • 功能类型:降压型(Buck)
  • 输出通道数:1 路
  • 工作电压(输入):典型 7V ~ 31V(系列某些版本可达 6.5V ~ 36V)
  • 输出电压:+5.0V(±3% 精度)
  • 最大输出电流:500mA(+5V 版本)
  • 转换效率:高达 90%(+5V/500mA 典型);系列 -5V 反向版本效率约 81%
  • 最大容性负载:680µF(+5V);-5V 版本 330µF
  • 静态电流(Iq):200µA(典型)
  • 纹波噪声:约 20mV p-p(典型)
  • 特性:短路保护
  • 尺寸(L×W×H):11.5mm × 7.55mm × 10.2mm
  • 封装:SIP-3P
  • 工作温度:-40℃ ~ +85℃

三、保护与可靠性

模块内置短路保护,能在输出过流或短路情况下自动限制输出,保护负载与模块本体。低静态电流设计有利于降低待机功耗,确保在长时间运行和电源断续条件下的稳定性。工作温度范围覆盖工业级要求,适合室温及较极端环境的长期工作。

四、机械与热特性

SIP-3P 小型封装利于插针式或直插 PCB 安装,占板面积小,适合紧凑型电源模块布置。虽然转换效率高,但在满载或输入电压差较大时仍需考虑散热——建议在高功率持续工作场景下预留周边铜箔散热面或采用自然对流/有限强制风冷以保持结温在安全范围内。

五、典型应用与选型建议

  • 工业控制与自动化设备:由 24V 母线降压至 5V 驱动控制器、传感器与通信模块
  • 嵌入式系统与单板计算:为微控制器、逻辑电路和外设提供稳压电源
  • 仪器仪表、数据采集、通信终端等需要高效率、小体积电源的场合 选型时建议确认输入母线电压上限、负载峰值与平均功率、以及模块在预期环境温度下的散热条件;如系统有浪涌或瞬态尖峰,考虑在输入端增加合适浪涌抑制元件。

六、安装与滤波建议

为保证稳定性与降低输出纹波,推荐在模块输入端并接 10µF100µF 的低 ESR 电解或固态电容,并在输出端并联 4.7µF100µF 的低 ESR 电容(但不超过规格允许的最大容性负载)。同时建议靠近模块引脚布置去耦电容与回流路径,缩短回路长度以减小 EMI 与环路噪声。注意模块引脚方向与接地良好连接,避免热沉或铜箔阻隔影响散热。

七、订购信息与注意事项

品牌:YLPTEC(易川);封装:SIP-3P。订购时请确认版本为 R-78E5.0-0.5(+5V/0.5A)并核对输入电压范围与工作温度需求。出于可靠性考虑,量产采购前建议进行样机评估,包括满载热试验、输入瞬态测试及长期老化验证,以确保在目标应用中的稳定性与寿命。

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
