SMD050F-2 产品概述
1. 产品基本信息
SMD050F-2 是一款由美国力特（Littelfuse）出品的正温度系数热敏电阻（PTC），专门设计用于电子电路中的过流保护。这款产品采用表面贴装类型（SMD），便于集成在各种电子设备中。其紧凑的封装尺寸和优秀的电气性能，使其非常适合于现代电子设备的应用需求。
2. 基本参数与性能特点
- 类型: 聚合物材料制成的PTC，具有良好的温度特性和电流保护能力。
- 电压-最大值: 该器件的最大工作电压为60V，适用于多种电压等级的电路设计。
- 电流-最大值: SMD050F-2的最大持续电流为10A，确保在高电流负载条件下仍能稳定工作。
- 电流-保持 (Ih): 器件的最大保持电流为500mA，意味着在此电流条件下元件可以正常工作而不会跳断。
- 电流-跳断 (It): 当电流超过1A时，PTC将迅速切断电流，防止电路遭受损坏。
- 跳断时间: 跳断所需时间为4秒，这对于多种应用来说是个合理的反应时间。
- 初始电阻 (Ri): 器件的初始电阻为最小350 mOhms，在正常工作条件下提供低损耗的电流路径。
- 跳断后电阻 (R1): 跳断后，电阻会增加到最大1.4 Ohms，进一步限制电流，确保系统安全。
- 工作温度: 可在-40°C至85°C的温度范围内稳定工作，使其在各种环境条件下均能保持良好的性能。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
