风华RC-01W56R0FT是一款针对高密度小功率电路设计的厚膜贴片电阻,属于0201超小型封装系列。产品核心定位为「高精度、低功耗、宽温适配」的基础被动元件,兼顾成本与性能,可覆盖便携电子、工业控制、车载等多领域需求。其核心特征包括:0201超小封装节省PCB空间、±1%高精度阻值、50mW低额定功率、-55℃~+125℃宽工作温度范围,适配自动化SMT贴装工艺。
标称阻值为56Ω,精度等级**±1%**,属于高精度厚膜电阻范畴。相比普通±5%精度电阻,该精度可满足信号调理、分压电路、反馈网络等对阻值准确性要求较高的场景,避免因阻值偏差导致电路性能波动。
额定功率50mW,最大工作电压25V。根据功率公式(P=V^2/R),25V时实际功耗约11.2mW,远低于额定功率,电压参数可安全覆盖功率范围,无需额外降额。
温度系数**±200ppm/℃**,表示每变化1℃,阻值变化为标称值的0.02%。以工作温差180℃(-55℃~+125℃)计算,阻值最大变化约2.02Ω,适合温度变化较平缓的场景,满足多数常规应用需求。
支持**-55℃+125℃**宽温工作,超出普通工业级(-40℃+85℃)标准,可适应车载、户外设备、工业现场等极端温度环境,避免温度漂移导致的电阻失效。
采用0201英制贴片封装(公制0.6mm×0.3mm),是当前体积最小的贴片电阻封装之一,优势包括:
智能手机、智能手环、蓝牙耳机等,小封装节省内部空间,低功耗满足电池供电需求,±1%精度保证信号链路稳定。
温度、压力传感器的信号调理电路,准确的分压/限流阻值可提升传感器输出准确性。
PLC输入输出模块、小型电机驱动电路,宽温范围适应工业现场温度波动,厚膜电阻稳定性确保长期可靠运行。
胎压监测、车载显示屏背光控制等,宽温(-55℃~+125℃)符合车载环境要求,低功耗适配汽车电源系统。
智能音箱、充电器辅助电路,成本可控,性能稳定,适合批量应用。
采用丝网印刷+烧结工艺,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,抗老化、抗潮湿性能优异,可适应90%以上相对湿度环境。
符合SMT工艺标准,耐回流焊峰值温度(260℃±5℃),焊接后无开裂、阻值漂移;机械性能满足GB/T 2693-2001标准,抗振动(10~2000Hz,2g加速度)、抗冲击(1000m/s²加速度)可靠。
符合RoHS 2.0、REACH指令,无铅无镉,满足全球市场环保要求;通过ISO 9001质量体系认证,品质管控严格。

本产品以「小体积、高精度、宽温稳」为核心优势,是高密度电路设计中平衡性能与成本的理想选择。
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.
