H1212S-2WR2 产品概述

一、概述

H1212S-2WR2 是 YLPTEC(易川)推出的小体积、高效率微功率隔离型 DC/DC 模块。产品为定电压、非稳压、单路输出设计,输出功率 2W,专为板上需要产生与输入电源隔离的场合而设计。模块采用 SIP 封装,体积小巧,便于密集布板与空间受限的系统应用。

二、主要参数

  • 输出通道数:1
  • 输入电压(Vin):10.8V ~ 13.2V(推荐输入电压波动±10%)
  • 输出电压(Vout):12V(定电压、非稳压)
  • 输出电流(最大):166mA
  • 输出功率:2W
  • 转换效率:约 86%
  • 最大容性负载:220µF
  • 隔离电压:6kV (Vrms)
  • 开关频率:100kHz
  • 纹波噪声:150mVp-p
  • 工作温度范围:-40℃ ~ +85℃
  • 尺寸(L×W×H):19.5 × 9.8 × 12 mm
  • 封装:SIP
  • 品牌:YLPTEC(易川)

三、功能与保护

  • 短路保护:内置短路/过流保护机制,遇到输出短路时限制输出或进入保护状态,从而保护模块与外部负载(具体行为参见技术手册)。
  • 过热保护:具备温度保护,超温时自动限制或关断输出,温度恢复后自动复位。
  • 隔离安全:6kV 隔离等级,适用于需要高隔离电压的板级系统。
  • 低纹波设计:典型纹波噪声 150mVp-p,适合数字及一般低频模拟电路使用。

四、典型应用场合

  • 板上隔离电源:在数字系统或通讯板上为隔离域提供 12V 电源。
  • 继电器驱动电路、开关驱动与逻辑驱动场合。
  • 数据交换、接口隔离与通讯端口供电(需要隔离以抑制共模干扰或保护接口)。
  • 低频模拟电路(对输出精度要求不高)及纯数字电路。

五、设计与使用建议

  • 输入端应保持在 10.8V~13.2V 范围;若输入起伏大,建议加装稳压或前端滤波。
  • 虽然模块能驱动容性负载,但最大容性负载为 220µF;超过会影响启动与稳定性。
  • 输出为非稳压类型,负载或输入变化时会有一定输出偏差;对精密供电请使用稳压方案。
  • 推荐在输入端并联滤波电容与熔断保护(保险丝),并在可能的瞬态环境下增加 TVS 或浪涌抑制器。
  • 布局上尽量缩短输入/输出回路,靠近模块焊盘放置去耦电容,避免长线产生干扰。
  • 模块靠近热源或密闭空间使用时需注意散热与通风,长期满载请留有散热裕量并按温度曲线做功率递减设计。

六、机械与环境要求

  • 封装:SIP,19.5×9.8×12 mm,适合通用插装或波峰/手工焊接。
  • 工作温度:-40℃ ~ +85℃,适用于宽温环境的工业级应用。
  • 安装时注意隔离爬电距离与爬弧要求,确保隔离性能满足系统安全规范。

七、订购与注意事项

  • 型号:H1212S-2WR2(YLPTEC 易川)
  • 使用前请参考厂方详细数据手册获取引脚定义、效率曲线、温升特性与保护行为说明。
  • 由于为非稳压隔离模块,不建议在对输出电压精度或低噪声有严格要求的精密模拟前端直接使用;必要时在输出端增加线性稳压或后级滤波。

H1212S-2WR2 在体积、效率与隔离性能之间取得良好平衡,是板级隔离供电、数字域供电及工业接口隔离的经济合适选择。

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.

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
