产品概述:MF-MSMF030-2 正温度系数热敏电阻(PTC)
一、产品简介
MF-MSMF030-2 是由 BOURNS 生产的一款高性能正温度系数热敏电阻(PTC)。该器件采用了表面贴装型设计,并具有自动恢复特性,主要用于过流保护和温度管理。其紧凑的1812封装(4532公制)使其非常适合于对空间要求严格的电子设备中。MF-MSMF030-2 提供了一种高可靠性和灵活性的解决方案,能有效保护电路免受过载以及短路等问题的影响。
二、基本参数
该 PT 具有以下重要的电气和物理特性:
电压和电流参数:MF-MSMF030-2的最大工作电压为30V,而最大电流可达10A。这使其适用于多种应用场合,例如电源管理、充电系统、以及各类电池保护电路。
保持电流与跳断电流:产品的保持电流(Ih,最大值)为300mA,即在正常工作条件下,电流不超过该值时,PTC维持低阻状态;而在电流达到600mA的跳断电流(It)时,PTC能够有效切断电流,保护连接的电路。
跳断时间与电阻特性:MF-MSMF030-2的跳断时间为100ms,意味着在过流情况下,PTC能够迅速反应,减小损坏的风险。其初始电阻(Ri,最小值)为300mOhm,跳断后电阻(R1,最大值)为3Ohm,这些特性确保在保护状态时电流被显著抑制,避免电路受到进一步的损坏。
工作温度范围:该器件在-40°C至85°C的工作温度范围内表现稳定,适应多种严苛的工况,这使得MF-MSMF030-2在汽车电子、消费电子、以及工业设备中具有良好的应用前景。
等级认证:MF-MSMF030-2符合AEC-Q200的标准,这为其在汽车行业的应用提供了重要的质量保证。
三、应用领域
MF-MSMF030-2广泛应用于以下领域:
汽车电子:在电动汽车(EV)和混合动力汽车(HEV)中,PTC通常用于电池保护,用以防止过流状态导致的电池损坏,确保电池组运行的安全性。
消费电子:该器件可用于手机、平板电脑、笔记本电脑等设备中,作为充电器和电源管理系统的一部分,保护电子组件免受意外的电流冲击。
工控设备:在工业自动化设备中,MF-MSMF030-2能够充当电流保护装置,确保系统稳定运行,避免因短路或过载带来的故障。
四、产品优势
自动恢复特性:相较于传统的熔断器,MF-MSMF030-2在跳断后能够自动恢复,避免了因元件损坏导致的系统停机问题。
高灵敏度与响应速度:该PTC具备快速响应能力,能够在几毫秒内完成跳断操作,提供高效的过流保护。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
