FH风华RC-02K202JT是一款厚膜贴片电阻,核心参数与型号命名对应关系明确:
适配高密度PCB设计,能有效缩小终端产品体积,尤其适合智能穿戴、蓝牙耳机等对空间要求严苛的设备;引脚间距小但焊接兼容性强,支持自动化贴片生产。
采用风华自研厚膜浆料配方,通过丝网印刷、高温烧结制成:
引脚采用Sn-Pb或无铅合金镀层,可焊性符合J-STD-002标准,支持回流焊、波峰焊等主流工艺,焊接良率达99.5%以上。
标称2kΩ±5%,满足消费电子、物联网终端的基础电路需求(如分压、限流、滤波),无需额外高精度电阻即可实现稳定功能;若电路对精度要求更高(如±1%),可替换为同系列F精度型号。
额定功率62.5mW,结合阻值计算得最大工作电压≈11.2V(V=√(P×R)=√(62.5e-3×2e3)),覆盖3.3V、5V等低电压系统的安全工作区间。
TCR为±100ppm/℃,表示温度每变化1℃,阻值漂移±0.2Ω(2kΩ×100×10⁻⁶);工作温度范围为-55℃~+125℃,在常规环境下阻值稳定性可靠,无需额外温漂补偿。
因小封装、低成本、稳定可靠的特点,该电阻广泛用于:
该产品平衡了成本、尺寸与性能,是小型化电子设备中基础电阻的优选方案。

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.
