R-78E3.3-1.0 产品概述
一、产品简介
R-78E3.3-1.0 是 YLPTEC(易川) 推出的降压型开关稳压模块（DIP封装），为单路3.3V输出的高效率降压转换器。输入电压范围广（6V~36V），最大输出电流1A，转换效率可达90%，适用于对体积、效率与成本有综合要求的电源设计。校验通过，可靠性良好。
二、主要电气参数
- 功能类型：降压型（Buck）
- 输入电压：6V ~ 36V
- 输出电压：3.3V，精度±3%
- 最大输出电流：1A
- 静态电流：300µA
- 纹波噪声：50mVp-p（典型）
- 开关频率：850kHz
- 最大容性负载：2200µF
- 温度范围：-40℃ ~ +85℃
三、功能特性与保护
- 高效率转换（最高约90%），减小发热与能耗
- 内置短路保护，出现故障后自动恢复（自动故障恢复），提高系统鲁棒性
- 低静态电流设计，适合电池供电或待机要求高的场景
四、典型应用场景
适用于嵌入式控制板、工业控制模块、通讯设备、传感器节点、车载与电池供电设备的3.3V电源模块，尤其在输入电压波动较大或需要较大容性旁路的场合表现稳定。
五、设计与使用建议
- 布局：输入端与开关器件之间走线最短、回路面积最小；输入与输出电容靠近模块引脚放置以降低纹波。
- 电容选择：建议采用低ESR陶瓷/铝电解混合，注意单个输出电容总容量不超过2200µF。
- 散热：在高输入电压或接近1A负载时注意散热，增加铜箔面积或散热片以降低结温。
- 保护与过滤：对较长输入线或含干扰源场合，建议并联额外的输入滤波与浪涌抑制元件。
六、机械信息与订购
- 封装：DIP（适合通孔焊接）
- 外形尺寸：长11.6mm × 宽7.5mm × 高10.2mm
- 品牌：YLPTEC(易川)；型号：R-78E3.3-1.0
该模块在尺寸、效率与保护功能间取得平衡，适合对稳定性与成本敏感的中小功率供电方案。若需参考电路布局图、输出纹波测试曲线或更多应用数据，可进一步索取规格书与参考设计。

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.
