电压和电流规格:
电阻特性:
环境适应性:
机械特性:
PTC 热敏电阻的工作原理基于其材料的正温度特性。当应用于电路时,它在低于设定的游标值的电流范围内保持较低的电阻。在电流超过设定的阈值(如在短路或过载情况下),PTC 将迅速升温,导致电阻显著增加,从而限制流过的电流。这一保护机制在电路的安全性和可靠性方面起着至关重要的作用,尤其是在电子设备及电源保护领域。
该 PTC 元器件广泛应用于以下领域:
MF-PSMF050X-2 具有如下一些显著优势:
MF-PSMF050X-2 正温度系数热敏电阻是一个功能可靠的电流保护方案,提供了坚固的电路安全保障。通过其优秀的电气特性、快速响应时间与小型化设计,它为各种电子设备提供了全面的解决方案,确保设备在操作过程中不会因电流异常而损坏。该产品的多样化应用使其成为现代电子设计中的一个重要元器件,值得工程师和设计师在相应领域中广泛采用。

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.
