FRC0402F18R0TS是富捷电子(FOJAN) 推出的一款0402封装厚膜电阻,针对高密度PCB布局、宽温环境下的小信号电路设计,兼具精准阻值控制、可靠稳定性与紧凑尺寸优势,广泛适配消费电子、工业控制、通信等领域的应用需求。
该电阻聚焦“小尺寸+精准+宽温”三大核心需求,核心特性可概括为:
18Ω属于电子电路中中等常用阻值(介于低阻<10Ω与中高阻>100Ω之间),±1%的精度意味着批量应用中阻值偏差可控制在17.82Ω~18.18Ω之间,无需额外校准即可满足多数信号调理、分压电路的精准要求,降低系统设计复杂度。
±100ppm/℃的温度系数表示:每变化1℃,阻值变化仅0.018Ω(18Ω×100×10⁻⁶)。在极端温差(-55℃~+155℃,温差210℃)下,最大阻值变化约3.78Ω,仍处于多数电路允许的偏差范围内,满足工业现场、车载等宽温场景的稳定需求。
-55℃+155℃的温度范围,不仅覆盖**工业级标准(-40℃+85℃),还可兼容部分汽车级辅助电路(最高125℃)**,无需额外降额使用,降低系统设计成本。
0402封装(英制尺寸:0.04英寸×0.02英寸;公制尺寸:1.0mm×0.5mm)是当前小尺寸被动元器件的主流封装之一,可显著减少PCB占用面积,适配智能手机、小型通信模块等对空间要求苛刻的产品。
采用厚膜丝网印刷工艺(陶瓷基板+电阻浆料烧结),相比薄膜电阻:
引脚设计符合回流焊工艺要求,焊接兼容性好,可适配SMT自动化生产线,提升生产效率与一致性。
该电阻的参数特性使其适用于以下场景:
FOJAN(富捷电子)是国内专注被动元器件研发与生产的品牌,厚膜电阻产品线已通过ISO9001质量管理体系认证、RoHS环保认证,产品符合欧盟环保要求。生产过程中采用自动化检测设备,确保每批次电阻的参数一致性与可靠性,适合中高端电子设备的批量应用。
总结:FRC0402F18R0TS以“精准阻值+宽温可靠+小尺寸”为核心优势,是高密度、宽温环境小信号电路的高性价比选择,可满足多领域电子设备的设计需求。
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.
