SMD1206B075TFT 是一款由台湾君耀(Brightking)公司生产的自恢复保险丝,采用1206封装。该产品设计用于在电路中提供过流保护,能够在电流异常时自动断开电路,并在故障排除后自动恢复,确保电路的持续稳定运行。其广泛应用于消费电子、通信设备、工业控制等领域。
保持电流(Hold Current): 750mA
该保险丝在正常工作条件下能够持续通过的最大电流为750mA,超过此电流时,保险丝将开始动作。
初始态阻值(Minimum Initial Resistance): 90mΩ
在正常工作状态下,保险丝的电阻值非常低,仅为90mΩ,确保电路中的能量损耗最小化。
跳闸电流(Trip Current): 1.5A
当电路中的电流达到1.5A时,保险丝将迅速动作,切断电路,防止过流对电路元件造成损害。
最大电压(Maximum Voltage): 8V
该保险丝能够承受的最大工作电压为8V,适用于低压电路的保护。
最大电流(Maximum Current): 100A
在极端情况下,保险丝能够承受的最大电流为100A,确保在短路等严重故障时仍能有效保护电路。
最大动作时间(Maximum Trip Time): 200ms
当电流超过跳闸电流时,保险丝将在200ms内迅速动作,切断电路,防止过流对电路元件造成损害。
工作温度范围(Operating Temperature Range): -40℃ ~ +85℃
该保险丝能够在极端温度环境下稳定工作,适用于各种恶劣环境。
自恢复功能: 与传统的熔断式保险丝不同,SMD1206B075TFT 具有自恢复功能。当电路中的过流故障排除后,保险丝会自动恢复导通状态,无需人工更换,大大降低了维护成本。
快速响应: 该保险丝具有极快的动作时间,能够在200ms内切断电路,有效防止过流对电路元件的损害。
低功耗: 初始态阻值仅为90mΩ,确保电路中的能量损耗最小化,提高整体电路的效率。
高可靠性: 采用高质量材料和先进制造工艺,确保产品在各种恶劣环境下稳定工作,具有极高的可靠性。
紧凑设计: 采用1206封装,体积小巧,适用于高密度电路板设计,节省空间。
SMD1206B075TFT 自恢复保险丝广泛应用于以下领域:
电流选择: 在选择保险丝时,应根据电路中的正常工作电流和最大电流选择合适的保持电流和跳闸电流,确保保险丝能够有效保护电路。
电压选择: 确保保险丝的最大电压不低于电路中的工作电压,防止保险丝在高压下失效。
温度环境: 在极端温度环境下使用时,应确保保险丝的工作温度范围符合实际应用环境,防止因温度过高或过低导致保险丝失效。
安装方式: 采用SMD封装,适用于表面贴装技术(SMT),安装时应注意焊接温度和时间,防止因焊接不当导致保险丝损坏。
SMD1206B075TFT 自恢复保险丝是一款高性能、高可靠性的电路保护元件,具有自恢复功能、快速响应、低功耗等优点,广泛应用于消费电子、通信设备、工业控制等领域。其紧凑的设计和优异的性能使其成为现代电子设备中不可或缺的保护元件。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
