FRC0402F3302TS是富捷电子(FOJAN)推出的一款0402封装厚膜贴片电阻,针对小型化、高精度电路设计需求优化,兼具成本优势与性能稳定性,广泛适用于消费电子、工业控制等多领域。
这款电阻以**“小尺寸+实用精度”**为核心设计方向:0402封装(约1.0mm×0.5mm)满足高密度PCB布局要求,±1%精度覆盖多数常规电路对阻值偏差的控制需求,62.5mW额定功率适配低功耗应用场景,避免了大功耗电阻的体积冗余。其设计初衷是为便携设备、小型传感器模块等对空间敏感的产品提供可靠的电阻解决方案,同时兼顾批量生产的成本效益。
标称阻值33kΩ,精度±1%,该精度等级能有效减少电路中的分压、限流偏差——例如在模拟信号调理电路中,避免因阻值误差导致的信号放大失真;在电池电量检测电路中,提升电压/电流测量的准确性。
额定功率62.5mW,工作电压50V,属于低功耗贴片电阻范畴。实际电路中需注意负载功率不超过额定值(如10V工作电压下,最大允许电流约0.625mA),避免过载发热失效。该参数适配多数低功耗电子设备的电源辅助电路、信号链路。
0402封装符合国际贴片标准,支持自动化贴装(SMT),与多数回流焊工艺兼容(峰值温度260℃左右);无铅环保设计符合RoHS指令,满足欧盟等地区环保要求。
厚膜电阻采用丝网印刷+高温烧结工艺制造,相比薄膜电阻成本更低,且具有以下优势:
智能手机、智能手表、蓝牙耳机等产品的PCB布局空间有限,该电阻可用于信号分压、按键电路限流、电池保护电路等场景——例如智能手表心率传感器的信号调理电路,需小尺寸电阻实现精准信号过滤。
PLC辅助电路、温度传感器模块、小型电机驱动电路等,需宽温适应性与稳定精度;该电阻的-55℃~+155℃温区可满足工业现场的温度变化(如车间昼夜温差),±1%精度保证传感器信号的准确采集。
小型基站、无线路由器的射频前端辅助电路、电源滤波电路等,高密度集成需求下,0402封装可节省空间,同时稳定的温度特性保证射频信号的一致性。
经多次可靠性测试(高温存储、温度循环、振动测试),FRC0402F3302TS的长期阻值漂移率≤0.5%,抗振动性能符合IEC 60068-2-6标准,可在复杂环境下稳定工作。此外,厚膜工艺的耐腐蚀性优于部分薄膜电阻,适合湿度较大的环境(如沿海地区设备)。
总结来说,FRC0402F3302TS是一款性价比突出的0402封装厚膜贴片电阻,兼顾小尺寸、高精度、宽温适应性,适用于多领域的低功耗电路设计,是电子工程师优化PCB布局与成本控制的可靠选择。
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.
