MF-R090 产品概述

概述

MF-R090 是一种高性能的聚合物自复位保险丝(PTC),可广泛应用于现代电子设备中,以提供过流保护,确保电路的安全性和稳定性。MF-R090 由知名品牌 BOURNS 生产,凭借其优异的电气性能及可靠的耐用性,成为众多设计师和工程师的优选。

产品特性

MF-R090 具有以下显著特性:

  1. 额定电流和电压: 此款保险丝的最大电流为 40A,最大工作电压可达 60V,使其能够适应多种电流和电压要求的应用。保持电流(Ih)为 900mA,确保在正常运行条件下稳定工作。

  2. 跳断特性: MF-R090 在检测到超过 1.8A 的过流情况时,会迅速跳断,确保电路中的其他元件不受损害。跳断时间约为 7.2 秒,具有足够的响应速度以保护电路。

  3. 电阻特性: 初始电阻(Ri)最小为 140 mOhms,在正常工作条件下提供低阻抗的优势;而跳断后的电阻(R1)最大为 470 mOhms,有助于其有效地隔断故障电流。

  4. 宽工作温度范围: MF-R090 的工作温度范围为 -40°C 至 85°C,适用于各种环境和应用场景,表现出的稳定性和可靠性都十分突出。

  5. 安装类型及封装: 该产品采用通孔安装,封装/外壳为径向圆片式,便于集成到电子设计中,且引线间距为 0.201"(5.10mm),适合标准的 PCB 设计。

  6. 尺寸: MF-R090 的尺寸为 0.461" 长 x 0.122" 宽(11.70mm x 3.10mm),高度最大为 0.657"(16.70mm),小巧的外形设计使其在空间有限的应用中更加灵活。

应用场景

MF-R090 聚合物自复位保险丝适用于多种应用场景,主要包括:

  • 消费电子产品: 如电脑、手机、平板及其他便携式设备,能够有效防止因过流引起的电路故障。
  • 家用电器: 例如微波炉、空调和洗衣机等设备,保障设备在异常情况下的安全运行。
  • 工业设备: 在生产线和重型机械中,MF-R090 可确保设备在高电流冲击下运行的安全性。
  • 通信设备: 适用于基站、路由器等场合,保护关键的通信组件。

为什么选择 MF-R090

选择 MF-R090 的原因可以归纳为以下几点:

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
