FH风华RC-02K105JT是一款0402封装工业级厚膜贴片电阻,隶属于风华电子常规电阻系列,主打「小体积高密度、宽温稳定、成本可控」三大核心优势,广泛适配消费电子、工业控制、物联网等对空间紧凑性与信号稳定性有要求的电路设计,是替代进口同类产品的高性价比选择。
该电阻的参数设计精准匹配常规电路需求,关键指标如下:
标称阻值1MΩ(10⁶Ω),精度**±5%**——满足大多数非高精度场景(如分压、限流、信号滤波)的误差要求,无需额外校准即可覆盖工业级与消费类电路的基础需求。
额定功率62.5mW(0.0625W),适配低功耗电路(如传感器前端、微控制器I/O口限流)。实际使用需注意:环境温度>85℃时,建议降额至额定功率的50%(避免热过载导致阻值漂移)。
±100ppm/℃——表示温度每变化1℃,阻值变化±100×10⁻⁶倍。以工作温区-55℃~155℃为例,温度跨度210℃,最大阻值变化量为21Ω(±2.1%),可有效保障宽温环境下的信号稳定(如户外工业设备、车载辅助电路)。
覆盖**-55℃~+155℃**,符合工业级环境温度标准,可应对极端低温(如北方户外设备)与高温(如车载电子舱内)场景,避免阻值失效。
采用0402封装(英制代码,公制尺寸≈1.0mm×0.5mm),是贴片电阻中最小的主流封装之一,适配高密度PCB布局(如智能手机主板、智能穿戴设备),可节省30%以上的电路空间。
FH作为国内电子元器件龙头,RC-02K105JT通过多项严苛测试:
该产品凭借「小体积+宽温稳定+成本优势」,成为中低端电路设计的主流选择,广泛应用于3C、工业、物联网等领域,是风华电子电阻系列中的经典型号。

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.
