RC-02K2052FT是风华电子(FH品牌)推出的0402封装厚膜贴片电阻,针对小型化、宽温环境下的电子电路设计,具备阻值精度适中、温度稳定性好、体积紧凑等核心特点,广泛适配消费电子、工业控制、汽车电子等领域的信号调理、分压限流、滤波网络等应用场景,无需额外校准即可实现稳定的电路性能。
该型号电阻的关键参数可满足多数中精度电路的需求,具体如下:
标称阻值为20.5kΩ,精度等级为**±1%**,可覆盖信号滤波、运放偏置、分压网络等对精度要求不苛刻但需一致性的场景,避免因阻值偏差导致的电路性能波动。
温度系数(TCR)为**±100ppm/℃**,即每变化1℃,阻值变化约2.05Ω(20.5kΩ×100×10^-6);在-55℃~+155℃全温区,最大阻值漂移约20.5Ω(210℃温差),适配工业现场、汽车舱内外等宽温环境下的阻值稳定性要求。
覆盖**-55℃~+155℃**,符合工业级及部分汽车级温度标准,可在极端环境(如沙漠高温、极地低温)下长期稳定工作,无需额外散热设计。
RC-02K2052FT采用0402封装(英制:0.04"×0.02";公制:1.0mm×0.5mm),属于贴片电阻的小型化规格,具备以下核心优势:
该型号电阻因体积小、宽温稳定、精度适中,广泛应用于以下领域:
符合IEC 61000-4-2(ESD抗扰度)、IEC 60068-2(环境试验)等国际标准,典型平均无故障时间(MTBF)>10^6小时,可满足工业级产品的可靠性要求,长期工作无明显性能衰减。
该型号电阻凭借稳定的性能、紧凑的体积和可靠的工艺,成为中小功率电路小型化设计的优选方案,可有效降低产品成本并提升集成度。

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.
