RC-02K2700FT是风华电子(FH) 推出的一款0402封装厚膜贴片电阻,属于通用型电子元件范畴。型号命名规则对应核心参数:
该电阻专为小型化、低功耗、高密度集成电路设计,是电子设备中分压、限流、信号调理等基础场景的常用元件。
阻值为270Ω(电子电路常用标准阻值),精度等级**±1%**——高于普通±5%精度电阻,可满足信号滤波、分压网络等对阻值精准度要求较高的场景,无需额外校准即可实现稳定电路性能。
额定功率62.5mW(1/16W),是0402封装贴片电阻的标准功率等级,适配低功耗设备(如便携终端、物联网节点)。需注意:实际电路中电阻功耗不得超过此值(计算公式:(P=I^2R=V^2/R)),避免过功率烧毁。
最大连续工作电压50V,脉冲电压需参考风华官方 datasheet(通常脉冲电压可适当放宽,但需避免瞬时过压)。确保电路电压不超额定值,可延长电阻使用寿命。
温度系数**±100ppm/℃**,即温度每变化1℃,阻值变化±0.01%。该特性使电阻在宽温范围保持阻值稳定,适合极端环境应用。
覆盖**-55℃~+155℃**,符合工业级与部分汽车级应用的温度要求,可在低温(北方户外设备)、高温(车载电子)场景下稳定工作。
采用厚膜丝网印刷+高温烧结工艺制造:
0402封装体积小巧,可节省PCB板空间,适配高密度集成设计(如智能手机主板、智能穿戴设备),提升设备集成度与便携性。
风华电子生产工艺符合ISO 9001等质量体系认证,电阻耐潮湿、抗振动性能优异,可在长期使用中保持性能稳定,降低设备故障风险。
RC-02K2700FT因参数适配性强,广泛应用于以下领域:
风华电子(FH)是国内电子元器件行业龙头企业,产品质量经市场长期验证,供货稳定、售后保障完善。
270Ω±1%是电子电路常用阻值,无需特殊定制即可满足多数基础电路需求,降低设计成本与周期。
厚膜工艺兼顾性能与成本,相比高精度薄膜电阻更具价格优势,适合大规模量产项目。
0402封装兼容主流SMT贴装设备,贴装效率高,易集成到现有PCB设计中,无需调整贴装工艺。
RC-02K2700FT凭借稳定的性能、合理的成本与广泛的适配性,成为电子设备基础电路的优选元件之一。
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.
