VISHAY CRCW0805100KJNEA 产品概述

一、主要特性

VISHAY(威世)CRCW0805100KJNEA 为厚膜贴片电阻,典型参数如下:

  • 标称阻值:100 kΩ
  • 精度:±5%(J)
  • 功率额定:0.125 W(1/8 W)
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 温度系数(TCR):±200 ppm/℃
  • 最高工作电压:150 V
  • 封装:0805(约 2.0 mm × 1.25 mm)
    该系列以成本效益高、可焊性好和批量一致性著称,适用于一般电子电路中的通用阻值需求。

二、产品描述与物理特性

CRCW0805 系列采用厚膜工艺制作,电阻膜通过丝网印刷或喷涂方式沉积在陶瓷基片上并经高温烧结,外形为 0805 封装(国际 0805 / 公制 2012)。该封装在面积与功率承载之间提供均衡,可在有限空间内实现 1/8W 的功率耗散。其表面涂层提高了抗潮湿和机械擦拭性能,端接处便于回流焊接与自动贴装生产。

三、典型应用场景

  • 消费类电子设备中的分压、限流与偏置网络
  • 工业控制与仪表的通用阻抗元件
  • 电源电路中的滤波和参考网络(非高精度场合)
  • 信号处理中的上拉/下拉电阻及阻值矩阵
  • 需要在较宽温度范围工作但对精度要求不高的应用

四、选型与设计注意事项

  • 精度与漂移:±5% 与 ±200 ppm/℃ 的 TCR 适合通用用途,但不适合高精度测量或温度敏感电路,如需更高精度或更低 TCR,请选择更高精度(1%/0.1%)或金属薄膜/金属膜电阻。
  • 功率与散热:标称功率为 0.125 W,为器件在一定参考条件下的额定值。实际电力耗散受 PCB 板上铜箔面积、周边元件和环境温度影响,建议参考厂商功率降额曲线并留有裕量。高温环境或密集布板时应考虑升档封装(例如 1206)或并联/并联布置来分担热负荷。
  • 最高工作电压:150 V 为器件在规定条件下允许的最高直流电压,电路中若存在浪涌或高压脉冲,应评估瞬态应力及爬电/击穿风险。
  • 温度范围:-55 ~ +155 ℃ 适应工业级温度要求,但在极端温度循环或长期高温应力下,阻值可能随时间产生漂移,建议做加速寿命评估。

五、焊接、存储与可靠性建议

  • 回流焊:遵循威世提供的回流焊温度曲线(详见规格书),避免超出推荐峰值温度与时间,以减少热应力导致的阻值漂移或端接开裂。
  • 保管与防潮:尽量在干燥环境中存放,长期储存应遵循包装上的防潮及储存期说明,必要时回流前进行烘烤。
  • 可靠性:厚膜电阻具有良好的机械稳定性和抗振动性,但在需高可靠性的应用(如关键航天/医疗器件)建议选择经过相应认证和特殊工艺的产品并进行老化/环境试验。

六、替代与扩展建议

  • 若需更高精度或更低 TCR,可选用薄膜或金属膜系列;
  • 若功率需求更大或热裕量不足,可考虑 1206、1210 等更大封装;
  • 若工作电压或浪涌较高,可选择具有更高电压等级或专用高压电阻。
    在最终选型前,建议下载并参阅 VISHAY 官方规格书(datasheet)以获取详尽的电气参数、功率降额曲线、温度系数曲线和焊接说明。

总结:CRCW0805100KJNEA 是一款面向通用电子应用的厚膜 0805 贴片电阻,特点为成本效益高、封装紧凑、适应宽温度范围。适合对精度要求不高但需可靠稳定阻值的常规电路设计。

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
