FRC0402F82R0TS是FOJAN(富捷)推出的一款0402封装厚膜贴片电阻,属于小功率高精度电阻范畴。该产品以紧凑体积、稳定性能为核心优势,适配高密度PCB设计与宽温环境应用,是消费电子、工业控制、汽车电子等领域的常规选型元件。其核心定位是“低成本+高可靠性”的平衡方案,既满足批量应用的成本控制需求,又能覆盖一般工业级场景的性能要求。
该电阻标称阻值为82Ω,精度等级为±1%(工业级常用精度,高于普通±5%电阻)。此精度可满足信号调理电路(如传感器分压、运放偏置)的阻值一致性需求,避免因阻值偏差导致的信号失真或电路性能波动。例如在12V电源分压为3.3V的电路中,82Ω电阻的±1%偏差仅会导致分压值波动±0.033V,远小于系统允许的误差范围。
采用国际标准0402封装(英制:0.04英寸×0.02英寸;公制:1.0mm×0.5mm),体积紧凑,适配高密度PCB布局(如智能手机主板、小型传感器模块),可有效减少电路体积与重量。
适配智能手机、智能手表、蓝牙耳机等便携设备的传感器信号处理电路(如加速度计、环境光传感器的分压/滤波),0402封装可压缩主板体积,±1%精度确保信号采集准确性。
应用于PLC模块、工业传感器(温度、压力传感器)的前端调理电路,宽温范围覆盖车间、户外控制柜等极端温度环境,厚膜工艺的稳定性减少长期阻值漂移。
用于车载传感器(胎压监测TPMS、车载摄像头)的信号偏置电路,宽温范围适配发动机舱高温(125℃)与冬季低温(-40℃),0402封装适合车载模块小型化设计。
应用于蓝牙、WiFi、LoRa等小型通信模块的射频匹配电路,82Ω阻值常用于天线与射频芯片的阻抗匹配,0402封装的低寄生参数(电感、电容)对射频信号损耗较小。
采用丝网印刷+烧结的厚膜工艺,相比薄膜电阻成本降低约30%,相比碳膜贴片电阻稳定性提升约20%(温度系数更低、耐温性更强),是“成本-性能”的最优平衡方案。
根据JEDEC JESD22-A104标准,功率降额曲线如下:
FOJAN(富捷)是国内专注贴片电阻研发生产的企业,产品通过RoHS 2.0、REACH SVHC环保认证,符合欧盟、北美市场要求。FRC0402F82R0TS采用全自动生产线,阻值一致性控制在±0.5%以内(远高于标称±1%),出厂前需经过100%阻值测试、温度系数抽样测试及功率老化测试,确保批量性能稳定。
FRC0402F82R0TS以“小体积、高精度、宽温适配、成本可控”为核心优势,覆盖多领域常规应用需求。其厚膜工艺的稳定性与0402封装的高密度适配性,使其成为批量电路设计的优选元件之一。

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.
