RC-02K3003FT属于风华厚膜贴片电阻系列,型号各段含义清晰:
该产品定位为“小封装高精度厚膜电阻”,平衡了成本与性能,满足多数中端电子设备的阻值精度需求。
RC-02K3003FT的核心参数围绕“精准、稳定、小功率”设计,具体如下:
参数项 规格值 说明 电阻类型 厚膜贴片电阻 陶瓷基片+印刷电阻浆料,烧结成型 标称阻值 300kΩ 300×10³欧姆 阻值精度 ±1% F级精度,优于普通±5%电阻 额定功率 62.5mW 0.0625W,适配低功耗电路 温度系数(TCR) ±100ppm/℃ 温度每变化1℃,阻值变化±0.01%,稳定性佳 工作温度范围 -55℃~125℃ 宽温适应不同场景(如工业、汽车辅助系统) 额定电压 ≈137V 由P=V²/R计算得出(√(62.5e-3×300e3) 封装尺寸 0402(1005) 1.0mm×0.5mm×0.4mm(典型值)注:额定功率为25℃环境下的最大值,实际使用需考虑环境温度影响(温度升高功率需降额)。
0402封装体积仅为1.0mm×0.5mm,相比0603封装体积缩小约60%,可显著提升PCB的器件密度,适合智能手机、智能穿戴等对空间要求严苛的设备。
采用氧化铝陶瓷基片(Al₂O₃)作为载体,印刷高精度厚膜电阻浆料后高温烧结,形成致密电阻层:
端电极采用三层结构(镍/铜/锡),符合RoHS 2.0无铅要求,适配回流焊、波峰焊等主流焊接工艺,焊接后附着力强,抗机械应力性能佳。
RC-02K3003FT因“小封装+高精度+宽温”特性,广泛应用于以下领域:
RC-02K3003FT是风华电子针对中端电子设备推出的高性价比厚膜贴片电阻,具备0402小封装、±1%高精度、62.5mW小功率、±100ppm/℃稳定TCR等核心优势,可满足多数低功耗、高密度场景的阻值需求,是消费电子、通信、工业控制等领域的理想选型。

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.
