  • 温度系数:±100ppm/℃,即温度每变化1℃,阻值漂移±2.7Ω(27kΩ×100×10⁻⁶),宽温下保持性能稳定;
  • 工作温度范围:-55℃~+155℃,覆盖工业级、汽车级严苛温度需求,极端工况下仍可靠运行;
  • 封装尺寸:0603(1.6mm×0.8mm×0.45mm),体积小、重量轻,适合便携设备高密度集成。

三、设计特点与应用优势

该电阻针对小型化、精密性与宽适应性优化,具备以下核心优势:

  1. 厚膜工艺保障一致性:采用丝网印刷厚膜工艺,批量生产阻值偏差小,降低电路调试难度;
  2. 小型化适配紧凑布局:0603封装节省PCB空间,适合智能手机、智能穿戴等便携设备;
  3. 精密性能满足专业需求:±1%精度+±100ppm/℃温度系数,可用于仪器仪表校准、工业传感器信号放大等场景;
  4. 宽温稳定抗环境干扰:-55℃~+155℃工作范围,结合厚膜电阻抗湿、抗腐蚀特性,适配工业现场、户外通信设备;
  5. 成本可控适合批量应用:厚膜工艺成本低于薄膜工艺,同时保持性能稳定,适合大规模量产终端产品。

四、典型应用场景

凭借参数与设计优势,该电阻广泛应用于:

  1. 消费电子:智能手机电源管理模块(DC-DC分压)、音频信号调理电路;
  2. 工业控制:PLC输入输出阻抗匹配、温度传感器信号放大、工业自动化控制单元;
  3. 仪器仪表:数字万用表量程校准、示波器信号衰减、精密测量参考阻抗;
  4. 汽车电子:车载信息娱乐系统信号处理、车身控制模块低压电路;
  5. 通信设备:小型基站电源滤波、路由器阻抗匹配、无线模块信号衰减器。

五、环境适应性说明

该电阻经KOA严格测试,可应对复杂工况:

  • 温度波动:-55℃+155℃内阻值漂移≤±100ppm/℃,满足汽车级(-40℃+125℃)与工业级(-40℃~+85℃)要求;
  • 湿度与腐蚀:表面涂层抗湿,可在90%相对湿度下长期工作,耐受弱酸碱环境;
  • 机械应力:焊接可靠性高,可承受PCB弯曲、振动,适合车载、工业振动场景。

综上,RK73H1JTTD2702F是一款兼顾小型化、精密性与宽适应性的高性价比厚膜电阻,可满足多数电子终端的电路设计需求。

Sourcing availability signal

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
