FRC0402F4992TS是富捷电子(FOJAN) 推出的一款0402封装贴片厚膜电阻,定位于小功率、高精度、工业级温度适应性的通用型电阻器件。其采用成熟厚膜工艺制造,兼顾成本控制与性能稳定性,广泛适配消费电子、工业控制、汽车电子等多领域的基础电路需求,是替代同规格进口电阻的高性价比选择。
标称阻值为49.9kΩ(即49900Ω),精度等级±1%——满足大多数信号调理、分压电路对阻值偏差的要求,无需额外校准即可实现稳定的电路参数输出,避免因阻值偏差导致的信号失真。
额定功率62.5mW(0.0625W)——适用于小电流信号路径(如偏置电路、传感器接口),避免功率冗余带来的成本浪费,同时保证在低功耗场景下的长期可靠性。
最大持续工作电压50V——结合阻值计算,50V下工作电流约1mA,功率消耗约0.05W(低于额定功率),可在安全范围内长期运行,无需额外降额设计。
温度系数为**±100ppm/℃**——温度每变化1℃,阻值变化±0.01%;在-55℃~+155℃全温区,阻值最大漂移约±2.1%,满足工业级环境的温度波动需求(如户外设备、车载高温场景)。
覆盖**-55℃+155℃**——超出常规商业级(0℃70℃)器件的温度范围,可适配极端低温(如北方户外监控)、高温(如发动机舱附近)场景,符合工业级器件的核心标准。
采用0402封装(英制)/1005封装(公制)——长度1.0mm、宽度0.5mm,小体积适配高密度PCB设计(如智能手机主板、小型工业模块),有效节省电路板空间,支持多器件密集布局。
引脚焊盘设计符合行业标准,兼容回流焊、波峰焊等常规贴片加工工艺,可直接集成于自动化生产流程,无需特殊设备适配。
富捷电子(FOJAN)作为国内电阻制造领域的资深厂商,FRC0402F4992TS具备以下优势:
综上,FRC0402F4992TS是一款性能均衡、成本可控的通用贴片厚膜电阻,可广泛应用于多领域的基础电路设计,是工程师优化电路方案的可靠选择。

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.
