B1212S-2WR2是YLPTEC(易川)推出的1通道隔离DC-DC电源模块,专为小功率、宽环境适应性场景设计,具备高效转换、完善保护、紧凑尺寸等核心优势,可满足工业控制、通信、车载等多领域的供电需求。
模块支持10.8V~13.2V宽输入电压范围,覆盖12V系统典型波动(如车载12V电源、工业12V母线);空载输入电流低至20mA,减少待机功耗,适合对低负载功耗敏感的场景。
输出电压稳定为12V,最大输出功率2W,对应最大输出电流166mA(2W/12V≈166.7mA);兼容最大220μF容性负载,无需额外负载适配电路;输出纹波噪声控制在100mVp-p,满足噪声敏感型应用(如信号采集)要求。
具备**1.5kV(有效值)**隔离电压,有效隔离输入输出端干扰,提升系统抗干扰能力,同时保障人员与设备安全。
开关频率固定为100kHz,处于EMI较低频段,简化滤波设计;转换效率达86%,处于同功率段主流水平。
86%转换效率下,满负载自身功耗仅约0.33W(2W/86%-2W≈0.33W),发热控制良好,无需额外散热片即可稳定工作,降低系统设计复杂度。
内置短路保护,输出短路时自动限流/关断,故障排除后自动恢复,避免模块或负载损坏,提升系统可靠性与维护便利性。
100mVp-p纹波噪声处于同类产品优良水平,避免干扰敏感电路(如模拟采集、通信收发器),保证电路稳定性。
模块尺寸仅19.5mm×7mm×10mm,体积小巧,可集成于空间受限的PCB布局,适合小型化设备(如手持终端、传感器节点)。
采用插件封装,便于手工/自动化焊接,降低装配难度;引脚机械强度高,可承受振动冲击,适配工业现场环境。
支持**-40℃~+85℃**,覆盖工业级典型温区(户外设备、车载系统、低温车间),无需温控措施即可稳定工作。
10.8V~13.2V输入范围可应对12V系统常见波动(电池放电、电网波动),无需额外输入稳压电路,简化设计。
B1212S-2WR2凭借核心优势,广泛适用于:
总结而言,B1212S-2WR2是高性价比小功率隔离电源模块,兼具高效、可靠、宽适应性与紧凑尺寸,是多领域系统设计的理想供电解决方案。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
