产品概述：MF-R110 正温度系数热敏电阻（PTC）
一. 基本信息
MF-R110 是由 BOURNS 公司设计和制造的一种正温度系数热敏电阻（PTC）。这种元器件的主要功能是作为过流保护器件，它能够在电路中智能地响应其环境条件，并有效地防止电流过载带来的损害。MF-R110 的外形设计为插件式，采用径向封装，尺寸为 0.350" 直径 x 0.118" 高（8.90mm x 3.00mm）。这种设计使得其在众多应用场景下具有极好的安装灵活性。
二. 关键技术参数
电气性能：
- 最大电压：MF-R110 能够支持高达 30V 的电压，使其适合多种电源电路的保护应用。
- 最大电流：此元器件在允许高达 40A 的连续工作电流下运行，确保在正常操作条件下设备的安全。
过流保护特性：
- 保持电流（Ih）：在加热时，MF-R110 的保持电流设定为最大 1.1A。这意味着在其工作状态下，电流不会超过此范围。
- 跳断电流（It）：一旦电流超过 2.2A，MF-R110 将激活跳断功能，迅速切断电路，避免潜在的设备损害。
- 跳断时间：该PTC在滑动过流引发的跳断中，最大跳断时间为 6.6秒。这一特性确保了即使在短时过载情况下，也能给予系统足够的保护。
电阻特性：
- 初始电阻（Ri）：其初始电阻为 100 mΩ（最小值），在正常工作情况下可以维持较低的能量损耗。
- 跳断后电阻（R1）：在跳断后，电阻升高至最高 270 mΩ，这样的设计确保了其能够在故障状态下有效隔离电流。
环境适应性：
- 工作温度：MF-R110 的工作温度覆盖范围为 -40°C ~ 85°C，这使其在极端气候或高温环境下仍具备良好的性能和可靠性。
机械特性：
- 安装类型：MF-R110 采用通孔安装类型，便于在传统PCB（印刷电路板）上焊接。
- 引线间距：其引线间距为 0.201"（5.10mm），方便与各种布局的电路板兼容。
三. 应用场景
MF-R110 在许多领域都有着广泛的应用，包括但不限于：
- 电源管理：在供电电路中，PTC 可以防止因短路或其他故障导致的过电流，确保系统的安全运行。
- 消费电子产品：如手机、电脑和家用电器等，MF-R110 作为过流保护器件，帮助提高设备的安全性和耐用性。
- 工业设备：在一些高功率的工业设备中，这种PTC能够有效防止过载和烧毁，确保设备的稳定运作。
- 汽车电子：在汽车电子系统中，MF-R110 有助于保护电机驱动、安全系统等高电流应用的重要电路。
四. 结论
总的来说，MF-R110 正温度系数热敏电阻（PTC）是一款高性能、可靠的过流保护器件。凭借其卓越的电气性能、宽广的工作环境适应性，以及广泛的应用场景，该产品无疑是提升设备安全性的重要组成部分。选择 MF-R110，不仅可以为您的设计带来额外的安全保护，还能增强整体产品的市场竞争力。

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.
