F1205S-2WR3 产品概述

一、产品简介

F1205S-2WR3 是 YLPTEC(易川) 推出的一款小体积、高效率的微功率隔离式 DC/DC 模块。模块为定电压、单路输出、隔离非稳压设计,主要用于在板级电源系统中产生与输入电源电气隔离的 5V 电源。器件采用 SIP-4 封装,体积小(19.5 × 7 × 10 mm),便于在空间受限的应用中直接安装在 PCB 上。

二、主要规格(关键参数)

  • 输出通道数:1
  • 输出功率:2W
  • 输入电压范围(Vin):10.8V ~ 13.2V(典型 12V 系统 ±10%)
  • 输出电压(Vout):5V(定值输出)
  • 输出电流(最大):400mA
  • 转换效率:86%(典型)
  • 隔离电压:3kV(3000 Vrms/≈3000 VDC 级别的隔离能力)
  • 开关频率:100kHz
  • 输出纹波噪声:50 mVpp(典型)
  • 最大容性负载:220 µF
  • 工作温度范围:-40℃ ~ +85℃
  • 保护功能:短路保护(自动恢复)、过热保护(自动故障恢复)
  • 封装:SIP-4;外形尺寸:长度 19.5 mm,宽度 7 mm,高度 10 mm

三、功能与保护特性

  • 短路保护:当输出短路或超载时,模块进入保护状态并在故障解除后自动恢复工作,无需人工复位,适用于对可靠性有要求的嵌入式系统。
  • 过热保护:当内部温度超过安全阈值时模块会触发热保护,降低输出或关断,待温度恢复后自动恢复输出,防止长期过热损伤器件。
  • 稳定输入条件:本系列适合输入电压相对稳定的场合(建议输入在 ±10% 范围内),对输入波动较大的场合需加上合适的前端稳压或滤波。

四、应用场景

  • 板上隔离电源:在通信、测控、工业控制或数据接口板上,为需要与主电源隔离的模块(如数据隔离、信号采集前端)提供小功率隔离电源。
  • 纯数字电路与低频模拟电路:如逻辑电平电源、接口电源、微控制器或小功率传感器供电(对输出精度要求不高的场合)。
  • 继电器驱动、小功率执行器和数据交换电路:为继电器线圈驱动或隔离收发器提供可靠的 5V 电源。
  • 适用于空间受限、需高隔离等级但功率需求较小的板级设计。

五、设计与使用建议

  • 输入要求:确保输入电压在 10.8V~13.2V 范围内;若系统输入不稳,应在输入侧增加稳压或滤波,以保证输出稳定性与转换效率。
  • 输出滤波:尽管模块自带一定滤波,若应用对纹波噪声敏感(例如高精度模拟测量),建议在输出端增加后级线性稳压或低噪声滤波电路。
  • 容性负载限制:最大容性负载为 220 µF,超出会影响启动及稳定性,应避免连接过大的电容负载。
  • 散热与布局:模块效率约 86%,在满载时仍会有损耗产生热量。建议在 PCB 布局时留出散热空间,避免贴近高温器件,并按需要做散热片或加装空气流通路径以提高可靠性。
  • 安全隔离:虽然模块具备 3kV 隔离能力,但在高压或安全相关应用中仍需根据系统标准处理爬电距、绝缘材料与外壳设计,并加配必要的安全保护(熔断、保险、接地等)。
  • 输入侧保护:为进一步提高系统抗干扰与安全性,推荐在输入侧加熔断器、TVS 或滤波器,用于应对瞬态冲击与异常过流。

六、典型性能参考

  • 满载输出 5V/400mA(2W)时,输出功率与效率(≈86%)决定了输入电流在 12V 条件下约为 0.19A(2W/12V/0.86 的近似值),具体取决于实际效率与输入电压。
  • 纹波噪声约 50 mVpp,适合数字电源及一般模拟场合,但对超低噪声场合建议加后级处理。

七、封装与采购信息

  • 品牌:YLPTEC(易川)
  • 型号:F1205S-2WR3
  • 封装形式:SIP-4,便于直插或贴片式插座安装
  • 外形尺寸:19.5 × 7 × 10 mm(长×宽×高)

总结:F1205S-2WR3 是一款面向板级隔离电源需求、具有短路自动恢复与过热保护的小功率隔离式 DC/DC 模块。其小巧的 SIP-4 封装和 3kV 隔离能力使其在工业控制、通信接口及板上隔离电源方案中具有较高的性价比与实用性。使用时注意输入稳定性、容性负载限制与散热设计,可获得可靠的长期运行表现。

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.
