RS-03K8203FT是风华电子(FH品牌) 推出的0603封装厚膜贴片电阻,针对小功率、高精度电子电路需求设计,核心参数清晰适配多数标准化场景:
该型号属于风华厚膜电阻系列的常规款,兼顾性能与成本,可直接替代同参数进口品牌产品。
±1%的精度可满足信号调理、分压电路等对阻值一致性要求较高的场景(如智能手机音频接口分压、工业传感器信号放大);厚膜工艺的陶瓷基底+厚膜电阻浆料结构,使阻值长期稳定性优于碳膜电阻,老化后阻值漂移率控制在0.5%以内(1000小时测试)。
100mW额定功率覆盖小功率电路的限流、分压需求(如5V电路中可承载约0.6mA电流);50V最大工作电压需严格遵守(过压易导致击穿),设计时建议预留10%-20%安全余量(即实际工作电压不超过40V)。
±100ppm/℃的TCR意味着温度每变化1℃,阻值变化约0.082Ω(820kΩ×100e-6);在-55℃~+155℃宽温区范围内,总阻值漂移控制在约1.68kΩ(210℃温差×0.082Ω/℃),可适应工业车间、车载环境等高低温场景。
0603封装(英制:60mil×30mil,公制:1.6mm×0.8mm)是贴片电阻的主流小封装,具备三大优势:
RS-03K8203FT因参数适配性强,广泛应用于以下领域:
FH(风华)是国内老牌电子元器件制造商,专注电阻电容研发30余年,具备三大核心优势:
该型号凭借高性价比、宽温区适配性,成为中低端电子设备的首选厚膜贴片电阻之一,可直接替代市场上同参数的进口品牌(如国巨、三星的0603封装820kΩ±1%电阻)。

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.
