  • 精度等级:±1%(工业级标准精度,出厂阻值偏差控制在标称值±1%以内,减少电路调试成本);
  • 额定功率:62.5mW(0402封装典型功率,适配小电流、低功耗电路,避免功率过载);
  • 最大工作电压:50V(持续工作电压上限,超出可能导致电阻性能下降或损坏);
  • 温度系数(TCR):±100ppm/℃(温度每变化1℃,阻值变化±0.01%,宽温范围内稳定性良好);
  • 工作温度范围:-55℃至+155℃(覆盖汽车、工业等场景极端温度,如车载-40℃至+125℃工况)。

三、关键性能特点

  1. 厚膜工艺优势:采用丝网印刷+高温烧结工艺,电阻膜层稳定性高,阻值一致性优于常规薄膜电阻,且成本更具竞争力,适合大规模量产;
  2. 小型化封装适配:0402封装尺寸(长1.0mm×宽0.5mm×厚0.3mm),可显著节省PCB空间,适配智能手机、智能穿戴等便携设备的高密度布局;
  3. 宽温稳定性突出:±100ppm/℃的TCR,在-55℃至+155℃范围内,阻值漂移量控制在合理区间,避免温度变化导致电路性能波动;
  4. 电气可靠性可靠:额定功率62.5mW、最大电压50V,经多次温度循环、湿度冲击测试,阻值变化率≤±0.5%,满足长期稳定运行需求;
  5. 环保合规:符合RoHS 2.0标准,无铅无镉,适配全球电子市场环保要求。

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
