YLPTEC F1205S-3WR2是一款适配12V系统的小功率隔离降压电源模块,核心功能为将10.8V~13.2V的输入电压(覆盖12V±10%的典型电压波动)转换为稳定的5V直流输出,最大输出功率3W。产品专为需要电气隔离的场景设计,可有效阻断输入输出间的地环路干扰,适合工业控制、通信设备、车载电子等对隔离防护、宽温适应有要求的领域。
具备3kV rms隔离电压,满足工业级隔离要求,可保护敏感负载免受高压串扰,同时提升系统安全性(如防止地电位差导致的设备损坏)。
输出纹波噪声低至30mVp-p,电源纯净度高,无需额外滤波即可适配模拟传感器、高精度AD采集等对噪声敏感的电路。
采用100kHz固定开关频率,电磁干扰(EMI)水平可控,可简化系统EMI滤波设计,降低整体成本。
采用SIP-4(单列直插式)封装,安装简便,可直接插装于PCB板,适合批量生产;引脚间距符合常规PCB规范,兼容性强。
模块尺寸为19.5mm(长)×7mm(宽)×10mm(高),体积紧凑,可轻松集成于空间受限的设备内部(如小型控制器、嵌入式模块)。
工作温度范围覆盖**-40℃~+85℃**,满足工业级宽温要求,可在低温(如北方户外设备)或高温(如设备内部散热空间有限场景)稳定工作。
内置输出短路保护功能,当输出端短路时,模块自动进入限流或关断状态,防止自身及负载损坏;故障排除后可恢复正常工作(无需手动重启)。
空载输入电流仅8mA,空载功耗低,适合长时间待机的设备(如低功耗传感器节点、待机状态下的通信模块),有效降低系统待机功耗。
最大容性负载达220uF,可兼容大负载电容,提升输出稳定性,避免负载突变时的电压波动。
转换效率达81%,在3W小功率隔离模块中处于良好水平。以满载工况为例,输入功率约3.7W,模块自身功耗约0.7W,发热可控,无需额外散热片即可稳定工作,进一步节省设备空间与成本。
YLPTEC F1205S-3WR2凭借宽电压输入、3kV隔离、小体积、宽温适应及短路保护等特性,成为12V系统转5V隔离供电的高性价比选择,可满足多数工业、通信及车载类小功率应用的需求。

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.
