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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
