BSMD1210L-500 产品概述
一、产品简介
BSMD1210L-500 为 BHFUSE（佰宏）出品的一款 1210 封装表贴可复位保险元件（PTC 自恢复熔断器），适用于 6V 及以下的低压电源保护场景。该型号设计用于在过流或短路情况下迅速限制电流，保护电路与负载，过载消除后可自动恢复，减少维护与更换成本。
二、关键电气参数
- 额定耐压（Vmax）：6V
- 最大瞬态电流（Imax）：50A
- 保持电流（Ihold）：5A（器件在该电流下长期不动作）
- 跳闸（触发）电流（Itrip）：10A
- 动作时间：约 5s（在接近跳闸电流条件下）
- 功耗（Pd）：1.5W
- 初始态阻值（Rmin）：1 mΩ
- 跳断后最大阻值（R1max）：12 mΩ
- 工作温度范围：-40℃ ~ +85℃
三、主要特点与优势
- 低电阻：初始阻值仅 1 mΩ，适合电源线和大电流路径，能量损耗小、效率高。
- 快速保护：在过流情况下能在短时间内限制电流，动作时间约为 5 秒（视过流幅度而变化）。
- 可复位：过流解除后自动冷却恢复，便于重复使用，适合频繁过载场景。
- 宽温适应：-40℃ 至 +85℃ 的工作温度范围，适应工业级与车载等更严苛环境（请结合实际环境做热设计）。
四、典型应用场景
- 便携式电源、锂电池组短路保护（6V 以内）
- USB/Type-C 电源保护、充电设备、电源适配器
- LED 驱动与显示模组保护
- 电机驱动、继电器线圈、汽车辅助电路的过流保护
五、选型与应用建议
- 留有余量：长期工作电流建议低于 Ihold，以避免不必要动作。短时冲击电流若接近 Imax，应评估器件温升与动作特性。
- 布局与散热：虽为低阻器件，但在高频繁动作或接近极限工况时会产生热量，建议合理走线、铺铜与靠近散热结构布局。
- 焊接与工艺：采用 1210 封装的标准 SMT 工艺安装，建议参照厂家详细数据手册的回流建议与焊盘设计以保证可靠性。
本概述基于 BHFUSE BSMD1210L-500 的关键参数整理，更多详细电气曲线、尺寸与焊接规范请参考厂家数据手册或联系供应商技术支持。

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.
