RC-01W3302FT是风华(FH)品牌推出的通用型厚膜贴片电阻,采用行业主流0201小型封装,核心参数匹配基础电子电路的小信号功率需求,是消费电子、小型工业设备等领域的高性价比选择。产品基础属性明确:阻值33kΩ、精度±1%、额定功率50mW,属于厚膜电阻技术路线下的标准化贴片元件,适配SMT(表面贴装技术)自动化生产,满足量产场景的效率要求。
产品阻值固定为33kΩ,精度等级**±1%**——介于低成本碳膜电阻(±5%)与高精度薄膜电阻(±0.1%)之间,既避免薄膜电阻的高成本,又能满足大多数信号调理、分压电路的精度需求(如传感器输出放大偏置、电源电压分压监测)。
额定功率50mW,最大工作电压25V——功率决定连续工作的最大功耗(P=V²/R,25V²/33kΩ≈19mW,远低于额定功率,故电压上限更严格),适合低功耗、小信号电路(如微控制器IO口上拉/下拉、小型LED驱动限流),不建议用于大功率负载。
温度系数**±200ppm/℃(温度每变1℃,阻值变±0.02%),工作温度范围-55℃~+125℃**——宽温覆盖满足工业级设备高低温需求(如户外传感器、汽车低温区辅助电路),温度系数处于厚膜电阻常规水平,保证温度波动下电路基本稳定。
0201封装尺寸为0.6mm×0.3mm(行业标准),是贴片电阻中体积较小的封装之一,适配高密度PCB设计(如智能手机主板、智能穿戴核心电路),有效减少电路板面积,提升设备集成度。
采用厚膜电阻工艺(丝网印刷电阻浆料→高温烧结→电极制备),相比薄膜电阻(真空沉积)成本更低,相比碳膜电阻稳定性更好,抗老化性能更优(长期使用阻值漂移小),适合批量应用。
RC-01W3302FT主要应用于低功耗、小信号、小型化设备,典型场景包括:
除-55℃+125℃工作温度,还能适应**5%95%RH**湿度范围(行业常规水平),满足户外设备湿度变化需求;
贴片封装配合SMT焊接,抗冲击(1000g/0.1ms)、抗振动(10~2000Hz/1g)性能良好,适合车载、手持设备等易受振动场景;
符合RoHS 2.0标准(无铅、无镉等有害物质),适配全球市场环保要求。
由风华高科(FH品牌) 生产,风华是国内电子元件龙头企业,拥有成熟厚膜电阻生产线,产品通过ISO 9001认证,批量一致性好(阻值分布集中),售后支持完善,适合量产客户长期供应需求。

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.
