ERJ3EKF2202V是松下(PANASONIC)推出的一款精密级厚膜贴片电阻器,采用0603小封装设计,针对小型化、高精度电子设备的需求优化,兼具稳定的电气性能与宽环境适应性,是工业控制、消费电子、汽车电子等领域的可靠无源元件选择。
该电阻属于松下厚膜电阻系列中的精密型号,区别于普通商用电阻,重点强化了阻值精度、温度稳定性两大核心指标,同时兼顾0603封装的高密度布局优势。其核心技术采用厚膜工艺:在氧化铝陶瓷基片上印刷精密电阻浆料,经高温烧结形成电阻层,既保证了成本可控,又能实现精密级性能,平衡了性能与量产性。
标称阻值22kΩ(标识代码“2202”,前两位“22”、第三位“0”、第四位“2”表示×10²),精度±1%——该精度满足多数信号调理、基准电路的需求,比普通±5%电阻的误差缩小5倍,可有效避免信号失真。
额定功率100mW,额定工作电压75V——在0603封装尺寸下,该功率等级适配小电流电路(如I=V/R=75V/22kΩ≈3.4mA),实际使用时需注意功率/电压不超过额定值,避免热失效。
温度系数(TCR)±100ppm/℃——表示每变化1℃,阻值变化±0.01%(100ppm=0.01%),在-55℃~+155℃宽温范围内,阻值漂移控制在合理区间,适合极端温度场景。
-55℃+155℃——覆盖工业级(-40+85℃)、汽车级(-40~+125℃)甚至更高温需求,抗高低温冲击性能优异。
采用0603封装(英制尺寸:0.06英寸×0.03英寸,公制1.6mm×0.8mm),是小型化电子设备的主流封装之一,核心优势包括:
该电阻经过松下标准的可靠性测试,关键验证项目包括:
综上,ERJ3EKF2202V凭借精密精度、宽温适应性、小封装密度三大核心优势,成为多领域小型化电子设备的理想无源元件,满足对性能与可靠性的双重需求。

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.
