B1215XT-2WR3 产品概述
一、简介
B1215XT-2WR3 是 YLPTEC（易川）推出的一款塑封 SMD-5P 小型隔离型 DC-DC 模块。该器件为双路输出、总功率 2W 的非稳压型变换器，专为板载电源系统中需要产生与输入电源隔离电压的场合设计，适用于纯数字电路、一般低频模拟电路和继电器驱动等应用。
二、主要性能参数
- 类型：塑封型，封装 SMD-5P
- 输入电压：10.8V ~ 13.2V（建议输入电压变化范围±10%）
- 输出：2 路，单路输出电压 15V，单路最大输出电流 133mA（总功率 2W）
- 转换效率：典型 80%
- 隔离耐压：1.5kV RMS（相当于约 2120V DC），适用于对隔离电压要求≤3000V DC 的场合
- 最大容性负载：2400µF
- 纹波噪声：100mVp-p（典型）
- 开关频率：260kHz
- 静态电流：5mA
- 功能特性：短路保护，自动故障恢复（自恢复型）
- 工作温度：-50℃ ~ +115℃
- 外形尺寸：12.7mm × 11.2mm × 7.25mm
三、应用场景与适用条件
B1215XT-2WR3 适用于：
- 输入电源幅值较为稳定（建议在额定值±10%以内）
- 需要输入/输出电气隔离的板上电源方案
- 对输出电压精度和低纹波要求不严格的数字电路、继电器驱动及一般低频模拟电路
注意：模块为非稳压型，输出电压会随输入电压与负载变化而变化；对精密模拟或对低噪声有严格要求的场合，应在模块输出端加线性稳压器或后级滤波。
四、设计与使用建议
- 输入侧应加适当旁路电容以抑制导线感抗和瞬态；输出侧根据负载情况配置滤波电容，避免超过最大容性负载 2400µF。
- 为降低输出纹波，可在输出端采用 LC 或 π 型滤波器，必要时并联低噪声 LDO 做后稳压。
- 虽具短路保护与自动恢复功能，但应避免长期短路或过载，以延长器件寿命。
- 模块工作时会产生一定热量，典型效率 80% 下损耗约为输出功率的 20%（例如满载时约 0.5W），在高环境温度或受限散热条件下应考虑散热或降载使用。
- SMD 安装时按厂家推荐的焊接工艺进行回流焊，避免过热影响可靠性。
五、产品优势与选型建议
B1215XT-2WR3 体积小、效率较高、支持国产化，适合批量应用在对隔离、体积和成本有综合要求的场合。选型时若关注输出稳定度或更低纹波，可考虑带有稳压功能或在模块后级加稳压器；若需更高隔离电压或更高输出功率，应选用相应规格的模块。

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.
