PTF-77是XFCN(兴飞)品牌推出的单通道支座型圆柱保险丝座,专为适配φ5×20mm标准圆柱保险丝设计,聚焦中低功率电路的过流保护集成需求。产品兼顾安装灵活性与可靠性,适用于空间紧凑、防护等级要求适中的电子设备,是小型家电、办公设备等领域的常规保护组件。
需确保电路工作电压≤250V、最大工作电流≤20A(保险丝额定电流需与电路峰值电流匹配,避免误熔断或过载失效)。
支座式结构支持两种主流安装场景:
单通道设计占用空间极小(整体尺寸约φ10mm×25mm,需结合具体型号确认),适配小型化设备内部紧凑布局。
导电件采用弹性卡接结构,保险丝插入后自动夹紧,确保接触紧密(接触电阻≤10mΩ),避免松动导致的发热或断路。
绝缘壳体全包裹导电部分,防止短路风险;宽温范围适应家电日常温度波动(如电饭煲加热时的温度变化)、办公设备长期运行环境。
PTF-77以其适配性强、安装灵活、可靠性高的特点,成为中低功率电路过流保护的常规选择,适用于对成本与性能平衡要求较高的电子设备。

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.
