BSMD1812-160-30V 产品概述
一、产品简介
BSMD1812-160-30V 是佰宏（BHFUSE）推出的一款高可靠性片式自恢复保险（PTC resettable fuse），封装尺寸为1812（0.18×0.12英寸 / 4.5×3.2mm）。该器件用于过流保护，体积小、轮廓低，适合表面贴装工艺，兼容常见无铅高温回流焊，满足 RoHS 无铅无卤要求。
二、主要电气与热学参数
- 最大耐压（Vmax）：30V
- 最大允许电流（Imax）：40A
- 保持电流（Ihold）：1.6A
- 跳闸电流（Itrip）：3.2A（典型）
- 动作时间：1s（在规定过流条件下）
- 功率耗散（Pd）：1W（额定参考）
- 初始阻值（Rmin）：30mΩ
- 跳断后阻值（R1max）：130mΩ
- 工作温度范围：-40℃ ~ +85℃
三、主要特性
- 对故障电流响应迅速，能在短时间内限制过大电流，保护下游电路与元件；
- 低初始阻值，正常工作时压降和能耗小；
- 自恢复特性：故障解除后可自动恢复导通状态（注意：若发生严重过流导致材料老化，仍需更换）；
- 低外形高度，适合空间受限的移动设备与多板系统；
- 与高温无铅焊料兼容，便于在标准 SMT 生产线上集成；
- 符合 RoHS，无铅无卤，满足环保与工业规范。
四、典型应用场景
适用于计算机与周边、智能手机与平板、多媒体设备的电源与接口保护；同时可用于汽车电子、工业控制、电话和宽带设备等需要过流保护的电源线路与模块，尤其适合对体积、响应速度和可靠性有要求的消费与工业类产品。
五、选型与使用建议
- 选型时应确保 Ihold 大于正常工作电流，并留有适当裕量，避免在长时间脉动或启动电流下误触发；Itrip ≈ 2×Ihold，本型号 Itrip 为 3.2A，适合短时冲击电流场合。
- 注意 Pd 与环境温度对温升的影响：在高温或密集布板中需适当降额使用，避免长期在接近额定功耗下工作。
- 跳断后器件阻值上升（R1max 130mΩ），可能影响电路恢复特性和压降，严重老化应替换。
- 推荐在贴装时遵循厂家回流焊工艺要求，避免过长高温暴露；储存时防潮、防挤压，以免机械损伤。
- 在关键应用中建议配合熔断器或电子开关做二次保护，以满足更高安全与可靠性要求。

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.
