FRC0402F1R20TS是富捷电子(FOJAN) 推出的一款0402封装厚膜贴片电阻,专为高密度电子电路设计。型号中:
产品定位为小体积、高精度、宽温适用的通用型贴片电阻,可满足消费电子、工业控制等多场景的信号调理、限流分压需求。
0402封装体积仅为0603封装的40%左右,可大幅压缩PCB布局空间,适配智能手机、可穿戴设备等对尺寸要求严苛的产品,同时支持高密度贴装(每平方厘米可达数千颗)。
±1%阻值精度满足信号校准、分压网络、限流电路等场景的精准度需求;±200ppm/℃的TCR确保温度从-55℃升至155℃时,阻值最大漂移仅约0.48%,宽温环境下性能稳定。
采用厚膜印刷+烧结工艺,电阻膜层与陶瓷基底附着力强,耐机械应力、环境腐蚀及长期老化,1000小时高温负荷测试后阻值漂移≤0.5%,寿命符合工业级标准。
-55℃至+155℃的工作温度覆盖了大多数电子设备的使用场景(如汽车低温启动、工业设备高温车间),无需额外散热设计,降低系统成本。
封装尺寸符合IEC 60115-1国际标准,可兼容全自动SMT贴装设备(贴装精度≤±0.05mm),焊接兼容性好,生产效率高。
额定功率62.5mW为25℃环境值,实际使用需按温度降额:
厚膜电阻抗静电能力优于薄膜,但仍需遵循ESD规范:
未开封产品存储于15-35℃、湿度40-60% 环境,开封后建议12个月内使用完毕;避免吸潮(吸潮后需120℃烘烤4小时)。
FRC0402F1R20TS凭借小体积、高精度、宽温稳定的核心优势,成为高密度电子电路设计的理想选择,广泛覆盖消费电子、工业控制、通信等多领域,可有效降低系统尺寸及成本,提升产品可靠性。

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.
