FRC0805F3001TS是富捷电子(FOJAN)推出的一款0805封装厚膜贴片电阻,针对中精度、宽温环境下的电子电路设计,核心参数匹配消费电子、工业控制等多场景需求,兼具成本优势与可靠性表现。
该电阻属于厚膜贴片电阻范畴,采用印刷工艺制备,以氧化铝陶瓷为基板,终端电极采用镍锡镀层(适配回流焊/波峰焊)。封装规格为0805(英制代码,对应公制尺寸2.0mm×1.2mm),是贴片电阻中应用最广泛的中尺寸封装之一,兼顾贴装密度与功率承载能力。
核心基础参数明确:
3kΩ±1%的精度,在批量生产中一致性良好,避免因电阻偏差导致的电路性能波动。例如在模拟量分压电路中,该精度可将信号误差控制在0.03kΩ以内,满足大多数工业传感器接口、电源反馈回路的需求。
125mW额定功率是0805封装的典型值,结合3kΩ阻值,可计算最大工作电流约为6.45mA(公式:(I=\sqrt{P/R}));150V工作电压需注意:当电压接近150V时,电流需低于6.45mA(避免功率超额定),实际应用中需根据电路工况综合考量,避免过压或过流。
±100ppm/℃的温度系数,意味着在工作温度范围(-55℃~+155℃)内,阻值最大变化量为:
(\Delta R = 3000\Omega \times 100ppm/℃ \times (155 - (-55))℃ = 6.3\Omega)
即阻值变化约±0.21%,结合±1%的精度,整体阻值偏差控制在±1.21%以内,可满足宽温环境下的长期稳定运行(如车载电子、户外监测设备)。
0805封装的尺寸紧凑(2.0mm×1.2mm×0.5mm左右,具体依厂商工艺),适合PCB板高密度贴装,尤其适合小型化产品(如智能手机、便携式医疗设备)。厚膜工艺的优势在于:
结合参数与工艺特点,FRC0805F3001TS的核心应用场景包括:
富捷电子(FOJAN)作为国内专业电阻制造商,该产品符合RoHS 2.0环保标准(无铅、无镉),并通过以下可靠性测试:
这些测试确保产品在批量应用中具备稳定的性能表现,降低售后维护成本。
总结来说,FRC0805F3001TS是一款高性价比、宽温适配、中精度的厚膜贴片电阻,0805封装的灵活性使其可覆盖多领域应用,是电子设计中限流、分压、信号调理的常用选择。

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.
