MF-MSMF020/60-2 是 Bourns Inc. 旗下 Multifuse® 系列中的一款高性能聚合物热敏自恢复保险丝(PTC,Positive Temperature Coefficient),专为在电子设备中提供过流保护而设计。此型号的主要特点和规格使其非常适合汽车、电信、消费电子以及工业应用等各种环境中使用。
MF-MSMF020/60-2 具备额定电压最大值为 60V 的能力,能够应对支持高电压的系统。这一点对于多种应用来说至关重要,尤其是在需要保护电路下游组件免受高电压冲击的场合。它的工作温度范围为 -40°C 至 +85°C,确保在最苛刻的环境条件下也能稳定运行,符合许多工业和汽车应用的需求。
此款自恢复保险丝的最大电流承受能力为 40A,意味着它可以在正常工作条件下安全传输相对较大的人流量。此外,其保持电流(Ih)设定为最大 200mA,提供了精确的过流保护。当电流超过其跳断值(It,400mA)时,保险丝会迅速断开电路,从而避免过流导致的潜在损害。
一个显著的特点是跳断时间,优于许多传统保险丝 - 在发生过流事件时,MF-MSMF020/60-2 的跳断时间约为 150ms,这意味着它能够迅速反应,从而降低设备损坏的风险,并提高整体系统的可靠性。
MF-MSMF020/60-2 的初始电阻(Ri)为至少 400mΩ。在跳断后,电阻值会上升至最大 6Ω,这种变化使其能够有效地限制故障条件下的电流,防止其他部件受到影响。此外,由于其为聚合物材料制成的自恢复保险丝,熔断后能够通过降温自我复位,恢复其工作状态,无需更换,这不仅降低了维护成本,也提升了设备的运行效率。
此产品采用的封装形式为 1812(4532公制),尺寸为 4.55mm x 3.24mm,厚度为 1.10mm,使其兼容大多数表面贴装(SMT)技术。在设计上,具有凹陷的外壳能够更好地固定在PCB上,从而增强连接的可靠性。工厂以卷带形式包装(TR),方便在生产中使用,大大提高了装配效率。
MF-MSMF020/60-2 还获得 cURus 和 TUV 等认证,确保其符合全球范围内的安全标准。此外,该产品符合 AEC-Q200 标准,特别针对汽车电子产品的高可靠性和耐用性设计,确保在极端环境下也不降低性能。
凭借其优秀的温度特性和过流保护性能,MF-MSMF020/60-2 广泛应用于各种场景。例如,在电动车辆中,提供电池管理系统的保护;在智能家居设备中,预防过载;以及在数据通信设备中,稳定系统运行,防止电路故障。
MF-MSMF020/60-2 作为一款高性能自恢复保险丝,充分展示了 Bourns Inc. 在电子元器件领域的专业性和创新能力。适用于多种行业,凭借其卓越的性能和灵活的安装方式,MF-MSMF020/60-2 成为保护电子设备的重要选择,为用户提供稳定的保护和长效的可靠性。

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.
