风华RC-01W1102FT是FH(风华)品牌推出的工业级厚膜片式电阻,属于常规高精度系列,针对小型化、低功耗、宽温稳定需求设计,适配0201英制封装,广泛应用于消费电子、工业控制等领域。型号中:
标称阻值11kΩ,精度±1%,属于行业通用高精度等级,可避免因阻值偏差导致的电路性能波动(如分压比偏移、运放偏置误差)。
温度系数(TC)±200ppm/℃:即温度每变化1℃,阻值变化±200×10⁻⁶。以11kΩ为例,温度从25℃升至125℃(变化100℃),阻值仅漂移±2.2Ω,满足工业级宽温要求。
-55℃~+125℃:覆盖极端高低温场景(如户外传感器、车载引擎舱),符合IEC 60068环境测试标准。
0201英制片式封装,尺寸为0.02″×0.01″(0.508mm×0.254mm),是当前小型化设备的最小常用封装之一,可节省PCB空间60%以上(对比0402封装)。
采用厚膜烧结工艺:
智能手机、智能手表、蓝牙耳机的信号调理电路(如滤波分压、运放偏置),因小尺寸、低功耗匹配设备紧凑设计。
小型传感器节点(温度/压力传感器)、PLC输入输出接口的信号放大电路,宽温范围适应工业现场-40℃~85℃的环境波动。
车载中控指示灯驱动、传感器偏置电路(若需车规级认证,可选择风华同系列RC-A汽车级产品)。
小型路由器、物联网网关的射频前端辅助电路,低功耗特性降低设备散热压力。
额定条件下工作寿命≥10000小时,阻值年漂移≤±0.1%,适合长期稳定运行的设备(如工业PLC、车载ECU)。
环境温度超过70℃时,需按风华降额曲线调整功率:
组装过程需遵循ESD规范(接触放电8kV、空气放电15kV),使用防静电工作台、手环,避免电极损伤。
风华RC-01W1102FT厚膜电阻凭借小尺寸、高精度、宽温稳定等特点,成为工业控制、消费电子等领域的常用基础元器件,可满足多数紧凑空间、低功耗电路的设计需求,是替代进口同规格产品的高性价比选择。

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.
