FRL1206FR390TS是FOJAN(富捷)推出的1206封装厚膜贴片电阻,针对中高精度、宽温适应性场景设计,核心聚焦低阻值(390mΩ)、±1%精准度与工业级环境耐受能力,适配电源管理、工业控制、消费电子等多领域需求,是小功率电路中电流检测、信号调理的可靠选择。
标称阻值为390mΩ(毫欧级),精度等级达**±1%**——该精度可有效避免阻值偏差对电流检测、反馈回路的影响,满足多数需要精准信号传输的电路要求(如I=V/R公式下的电流采样)。
温度系数(TCR)为**±300ppm/℃**,即在-55℃至+155℃范围内,每变化1℃,阻值变化率控制在±300×10⁻⁶以内,保证宽温环境下阻值稳定性,无需额外温控补偿。
覆盖**-55℃至+155℃**,符合工业级环境温度标准,可应用于户外、高温车间、低温仓储等极端场景,适配设备长期稳定运行。
采用行业标准1206贴片封装(英制:长120mil≈3.05mm,宽60mil≈1.52mm;公制对应3216),具有以下优势:
厚膜印刷工艺使电阻膜层与陶瓷基底结合牢固,抗冲击、抗振动性能优异(可承受10G以上振动),适配运输与使用中的机械应力。
产品符合RoHS 2.0、REACH等全球环保指令,无铅无镉,适配欧盟、北美等市场准入要求。
FOJAN(富捷)作为国内专业电子元件制造商,拥有10余年厚膜电阻生产经验:
FRL1206FR390TS凭借精准阻值、宽温耐受与高可靠性,成为小功率电路中替代传统插件电阻的理想选择,适配多行业的多样化需求。

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.
