BSMD1206-075-30V 产品概述
一、产品简介
BSMD1206-075-30V 是佰宏（BHFUSE）推出的一款 1206 封装自恢复保险（聚合物 PTC），专为中低电流保护设计。标称保持电流 0.75A、工作电压最高 30V，适用于 USB、电源轨与便携设备等短路/过流保护场合。
二、主要特性
- 封装：1206（长度 3.6mm × 宽度 1.9mm × 高度 1.0mm）
- 保持电流（Ihold）：750mA（典型）
- 跳闸电流（Itrip）：1.5A（典型）
- 初始态阻值（Rmin）：90mΩ
- 跳断后最大阻值（R1max）：500mΩ
- 最大耐压（Vmax）：30V
- 最大功耗（Pd）：800mW
- 最大瞬态容许电流（Imax）：40A（短时突发）
- 动作时间：200ms（典型）
- 工作温度：-40℃ ~ +85℃
三、参数含义与注意点
- Ihold 为设备在规定温度下长期能承载的电流，设计时应留有裕量，持续工作电流建议低于 Ihold。
- Itrip 为在过流发生时元件开始显著升阻并限制电流的值；若电路有较大冲入电流（inrush），应保证不会引起误触发。
- Rmin/R1max 表征复位前后的电阻变化；复位后阻值回归但通常高于初始值。
- Imax 为短时耐受浪涌电流，非连续工作值，选择时需考虑冲击持续时间。
四、典型应用
适合 USB 接口保护、充电线路、便携式电子产品、音视频设备及一般 30V 以下电源轨的过流保护。对汽车高温工况需求高的场合需评估封装热裕度和认证要求。
五、选型与安装建议
- 选型时以最大持续电流与预期工作环境温度为主，若环境温度高，应选更高等级或留更大裕度。
- 避免并联小尺寸自恢复保险器以提高容量，推荐改用单颗额定更高器件。
- 采用标准 1206 焊盘布局，按厂家回流曲线进行焊接，避免机械应力与过度清洗溶剂浸泡。
- 对关键产品建议做热仿真评估 PCB 散热对器件性能的影响。
六、可靠性与合规
器件耐温范围宽，对常规消费类与工业类电子设备可靠性要求满足；若需 UL、IEC 或汽车级认证，请向佰宏索取完整数据表与认证文件以核实。
如需电气浪涌曲线、温度漂移特性或回流焊工艺参数，我可协助整理并给出 PCB 布局与热管理建议。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
