RC-02K3482FT是风华电子(FH品牌)推出的超小型厚膜贴片电阻,型号命名遵循行业通用规则:
该产品采用0402封装(英制尺寸:0.04英寸×0.02英寸,约1.0mm×0.5mm),核心定位为“高密度、低功耗电路的经济型电阻解决方案”。
RC-02K3482FT的参数覆盖工业级通用需求,关键指标如下:
0402封装优势:
超小型尺寸大幅节省PCB空间,适合智能手机、可穿戴设备等对体积要求严格的产品;表面贴装设计兼容回流焊、波峰焊,生产效率高。
厚膜工艺特性:
采用丝网印刷+高温烧结工艺制备电阻膜层,膜层厚度较薄膜电阻更厚,具备更好的抗过载能力(短时间过载功率可达额定值2~3倍);同时厚膜工艺成本低于薄膜电阻,性价比优势明显。
环保兼容性:
符合RoHS2.0、REACH环保标准,无铅焊接兼容,满足全球市场环保要求。
RC-02K3482FT因“小型化、低功耗、中等精度”的特点,广泛应用于以下领域:
可靠性表现:
厚膜工艺赋予其较好的长期稳定性(125℃高温老化1000小时,阻值漂移≤0.1%);抗机械应力能力强,可适应柔性PCB弯曲变形(如可穿戴设备)。
功率降额要求:
环境温度超过25℃时需降额使用(如100℃时额定功率降至约30mW),避免过热失效。
ESD防护:
耐受能力±2kV(人体模型),满足一般电路需求;高ESD场景需额外增加防护措施。
RC-02K3482FT是一款平衡成本与性能的厚膜贴片电阻,在小型化、精度、功率之间实现了实用化匹配,可覆盖消费电子、工业控制、通信等多领域的低功耗高密度设计需求,是风华电子成熟的电阻产品之一。

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.
