Bourns Inc. Multifuse® MF-R300 产品概述
Bourns Inc. 是一家领先的电子元器件制造商，以其创新的电路保护解决方案而闻名。MF-R300 是其 Multifuse® 系列中的一种聚合物正温度系数（PTC）自恢复保险丝，专门设计用于在电流过载情况下保护电路，确保设备在极端条件下的安全和稳定运行。
产品特性与规格
MF-R300 的主要参数包括：
- 电压最大值: 30V
- 电流最大值: 40A
- 保持电流 (Ih): 3A
- 跳断电流 (It): 6A
- 跳断时间: 10.8秒
- 初始电阻 (Ri): 最小 20 mΩ
- 跳断后电阻 (R1): 最大 80 mΩ
- 工作温度范围: -40°C 至 85°C
这种保险丝的设计采用径向圆片式封装，方便通过通孔安装。它的尺寸为 12.00mm x 3.00mm，最大安装高度为 18.30mm，引线间距为 5.10mm。这些规格使其能够融入多种应用中，广泛适用于需要电流保护的小型电子设备和电路板。
工作原理
MF-R300 利用其聚合物材料的特殊性质作为自恢复保险丝。在正常工作条件下，设备通过此保险丝的电流显示出稳定的低电阻。然而，当电流超过预设的跳断电流（6A）时，PTC 保险丝内的聚合物材料会迅速加热，导致其电阻大幅增加，从而切断电路，防止电流继续通过，从而有效保护下游设备。
一旦电流恢复到安全水平，PTC 组件会降温，电阻下降，自恢复到正常状态。这种自恢复的特性消除了传统保险丝需要更换的物理缺陷，减少了维护成本和停机时间。
应用场景
MF-R300 适用范围广泛，特别是在以下领域表现出色：
- 消费电子产品: 如手机、平板电脑、笔记本电脑等，能有效防止电池过载和电路损坏。
- 工控设备: 在复杂的工业设备中，能够保护电路免受过电流影响，确保设备的正常运行。
- 家电: 在冰箱、洗衣机等家用电器中，能够对电机和电路提供可靠的保护。
- 通信设备: 应用于路由器、交换机等网络设备，确保数据传输不受电流异常影响。
可靠性与认证
MF-R300 经过 cURus 和 TUV 认证，确保其符合国际安全标准。这些认证为用户提供了有力的信心，保证产品在各种工作环境下具有高可靠性，尤其是在要求严格的工业和消费领域。
结论
Bourns Inc. 的 MF-R300 Multifuse® 产品是一个出色的电流保护解决方案，适用于需要高可靠性和良好性能的各种电子应用。其自恢复特性、稳定的跳断性能及宽广的工作温度范围，使其成为现代电子设备中不可或缺的组件。通过引入 MF-R300，设计工程师可以更好地应对电流保护需求，确保产品的长期稳定性和用户的安全使用。

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.
