RC-02K112JT厚膜贴片电阻产品概述

RC-02K112JT是风华高科(FH品牌)推出的一款0402封装厚膜贴片电阻,针对小体积、低功耗、宽温环境下的基础电路需求设计,核心参数覆盖1.1kΩ阻值、±5%精度、62.5mW功率,是消费电子、工业控制等领域的常规选型元件。

一、产品核心定位

该电阻属于商用级厚膜贴片电阻,聚焦三大核心需求:

  1. 小体积适配:0402封装(公制1005)满足高密度PCB布局;
  2. 宽温稳定:-55℃~+155℃工作范围覆盖工业及部分高温场景;
  3. 成本可控:厚膜工艺实现性能与成本的平衡,适合大规模量产应用。

二、关键参数详解

2.1 阻值与精度

  • 标称阻值:1.1kΩ(对应丝印标识“112”,即11×10²Ω);
  • 精度等级:±5%,属于商用级标准精度,可满足多数民用/工业基础电路的误差容忍要求(如分压、限流、信号匹配等)。

2.2 功率与电流承载

  • 额定功率:62.5mW(即1/16W),是0402封装厚膜电阻的典型功率等级;
  • 最大电流:由公式(I_{max}=\sqrt{\frac{P}{R}})计算,约7.57mA,适配低功耗电路的电流承载需求。

2.3 温度特性

  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化约0.011Ω(1.1kΩ×100×10⁻⁶);
  • 宽温阻值漂移:在-55℃~+155℃范围内,最大阻值变化约±23.1Ω(1.1kΩ×210℃×100×10⁻⁶),保证电路性能一致性。

2.4 工作环境范围

  • 温度范围:-55℃至+155℃(高于常规商用级的125℃上限);
  • 存储温度:配套为-65℃~+155℃(参考风华官方datasheet),适配极端环境存储。

三、封装与工艺特点

3.1 0402封装优势

  • 尺寸规格:英制0402(公制1005),即1.0mm(长)×0.5mm(宽)×0.35mm(厚);
  • 布局适配:小体积可显著提升PCB单位面积的元件密度,适合智能手机、智能穿戴等小型化设备。

3.2 厚膜电阻工艺

  • 制备流程:采用丝网印刷钌基厚膜电阻浆料于陶瓷基板,经高温烧结、镍锡电极制备而成;
  • 性能特点:阻值范围宽、成本低、长期稳定性好,适合批量生产。

3.3 焊接兼容性

  • 焊接方式:支持回流焊、波峰焊等常规贴片焊接工艺;
  • 可靠性:电极采用镍锡镀层,焊接附着力强,符合J-STD-020行业标准。

四、典型应用场景

该电阻的参数特性使其适配多领域基础电路需求:

  1. 消费电子:智能手机、智能手表的信号分压、电源滤波电路(0402封装适配小体积);
  2. 工业控制:传感器接口、低功耗PLC模块的阻抗匹配(宽温范围适应工业现场);
  3. 物联网(IoT):低功耗节点的信号调理、电源限流电路(62.5mW功率满足低功耗);
  4. 通信设备:小型基站、无线模块的射频前端辅助电路(小体积适配高密度布局);
  5. 汽车电子(辅助场景):车载小功率电路的温度补偿电阻(155℃上限覆盖部分高温区)。

五、风华品牌(FH)保障

  1. 国产龙头优势:风华高科是国内厚膜电阻领域核心供应商,产能稳定,质量可控;
  2. 环保合规:符合RoHS 2.0、REACH等全球环保标准,无铅无卤;
  3. 技术支持:提供完整datasheet、选型指南及应用技术支持,便于设计选型;
  4. 供应链稳定:大规模量产能力,交货周期可控,适合批量采购需求。

六、总结

RC-02K112JT作为一款高性价比厚膜贴片电阻,以小体积、宽温稳定、成本可控为核心优势,覆盖消费电子、工业控制、物联网等多领域的基础电路需求,是工程师选型常规阻抗元件的优选方案。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
