RC-02K333JT是风华电子(FH品牌) 推出的一款通用型厚膜贴片电阻,属于0402封装系列核心型号。该器件以33kΩ为标称阻值,适配±5%精度要求,是电子电路中实现分压、限流、阻抗匹配、信号滤波等基础功能的常用元件,广泛覆盖消费电子、工业控制、车载辅助等领域。
该型号的关键参数针对通用场景做了均衡设计,具体如下:
标称阻值为33kΩ(33×10³Ω),精度±5%,实际工作阻值范围为31.35kΩ~34.65kΩ,无需额外校准即可满足绝大多数民用/工业通用电路的误差需求。
额定功率62.5mW(0.0625W),对应0402封装的常规功率等级。由公式 ( I = \sqrt{P/R} ) 计算,最大连续工作电流约为1.37mA,适合小电流、低功耗场景(如LED指示灯、传感器接口)。
±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%。例如:当环境温度从25℃升至155℃(温差130℃),阻值变化约±1.3%,稳定性优于普通碳膜电阻,可适应温度波动较大的工作环境。
-55℃~+155℃,覆盖工业级(-40℃+85℃)和部分汽车级(-40℃+125℃)温区,能在极端低温(北方户外设备)和高温(车载电子舱内)下稳定工作。
采用厚膜工艺制造:相比薄膜电阻成本更低,厚膜层耐过载能力更强(可承受短时间过功率冲击),适合批量生产的一致性要求。
结合参数特点,该型号主要适配以下场景:
RC-02K333JT由风华电子(国内厚膜电阻龙头企业)生产,核心优势如下:
0402英制封装(公制1005),尺寸为1.0mm×0.5mm,紧凑设计适合高密度PCB(如智能手机主板、IoT模块),可显著节省电路板空间。
若现有参数无法满足需求,可参考以下升级方向:
综上,RC-02K333JT是一款性价比突出的通用厚膜贴片电阻,以均衡的性能覆盖多领域应用,适合对成本敏感且需宽温、小封装的电路设计。
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.
