RC-02K1371FT是风华电子(FH)推出的0402封装厚膜贴片电阻,型号编码直接映射核心参数:
该产品定位为中等精度、小功率、宽温适配的通用型贴片电阻,精准匹配高密度PCB设计需求。
阻值1.37kΩ属于E96系列(±1%精度专用阻值体系),无需定制即可满足常规电路的匹配需求。±1%的精度平衡了成本与性能:既避免高精度电阻(如±0.1%)的溢价,又能覆盖信号调理、分压、限流等场景的误差要求(如工业传感器接口的0.5%~2%误差容忍度)。
额定功率62.5mW(即1/16W),是0402封装厚膜电阻的典型功率等级。需注意:该值为25℃环境下的额定值,高温场景需按降额曲线使用(如155℃时功率降额至约10mW),避免长期过功率导致阻值漂移或失效。
温度系数(TCR)±100ppm/℃,表示每变化1℃,阻值变化±100ppm。以极限温差(-55℃→155℃,温差210℃)计算,阻值最大变化量为:
1.37kΩ × 100ppm × 210 = 28.77Ω(约2.1%)。
虽略高于精度指标,但实际应用中温度波动远小于极限值(如车载环境通常为-40℃~85℃),因此可稳定适配宽温场景。
工作温度-55℃+155℃,覆盖汽车级(-40℃125℃)与工业级(-55℃~125℃)核心需求,部分高温场景(如LED驱动模块)也可兼容。
0402封装(1.0mm×0.5mm)是贴片电阻中尺寸较小的规格之一,能大幅节省PCB空间,适配智能手机、智能穿戴、小型通信模块等高密度集成设计。其焊盘尺寸与贴装工艺成熟,可兼容常规SMT生产线(贴装精度要求≤±0.1mm)。
采用厚膜陶瓷工艺制造:将钌基电阻浆料丝网印刷在氧化铝陶瓷基片上,经1000℃以上高温烧结形成电阻层,再覆盖玻璃保护层。相比薄膜电阻,厚膜工艺具有:
该工艺确保了产品长期稳定性:经老化测试(125℃/1000小时)后,阻值漂移率通常≤0.5%。
RC-02K1371FT的参数匹配多种常规电路,核心应用包括:
风华作为国内老牌元器件厂商,RC-02K1371FT通过多项可靠性测试:
产品遵循ISO9001质量体系,部分批次通过IATF16949汽车电子认证,适配对可靠性要求较高的场景。
该产品以高性价比、宽温适配性与小封装优势,成为消费电子、汽车电子等领域的通用优选电阻。

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.
