SMD1206B175TF 是为低压、可重复保护设计的表面贴装自恢复保险丝。器件在正常工作电流下呈现低阻状态(典型初始阻值约 20 mΩ),当过电流超过其跳闸点(约 3.5 A)并持续一定时间(典型 500 ms)时,内部材料加热产生电阻显著上升(动作后阻值 ≤ 90 mΩ),限制故障电流,从而保护电路。故障解除且冷却后可自动恢复到低阻态,适合多次保护循环使用。
主要特性:
SMD1206B175TF 适合用于 6 V 以下、需要小体积、可重复过流保护的消费类与工业电子设备。当设计电流接近或超过 1.75 A 时,应选用保持电流更高的型号或增加安全裕度;在高温或频繁浪涌场合,建议通过测试验证或选用更高额定值的自恢复保险丝。该器件结合小体积、较低初始阻值与良好瞬态承受力,在 USB、电池保护与小电流电源防护中具有良好适用性。

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.
