ERTJ1VA220H NTC热敏电阻产品概述
一、核心身份与品牌定位
ERTJ1VA220H是松下（PANASONIC）推出的0603封装片式负温度系数（NTC）热敏电阻，属于松下热敏电阻产品线中的小型化、高精度型号。依托松下在电子元器件领域的工艺积累与可靠性验证，该型号具备稳定的温度-电阻特性，可适配各类对体积、精度有要求的温度监测与控制场景。
二、核心参数总览
该型号的关键参数可分为电阻特性、功率特性、温度特性及物理规格四类，具体如下：
- 电阻特性：标称阻值22Ω，阻值精度±3%；B值在25℃/50℃区间为2750K，25℃/85℃区间为2700K，B值精度均为±3%；
- 功率特性：额定功率100mW，耗散系数3mW/℃；
- 温度特性：工作温度范围覆盖-40℃~+125℃；
- 物理规格：0603片式封装，尺寸为1.6mm（长）×0.8mm（宽）×0.8mm（高）。
三、关键性能特性解析
- 高精度温度-电阻转换：阻值与B值均采用±3%精度设计，确保产品在不同温度下的阻值变化具有高度一致性，减少了温度测量或补偿电路中的误差，适合对精度要求较高的场景；
- 低自热效应：耗散系数仅3mW/℃，意味着电阻工作时产生的热量极少，不会明显干扰被测环境温度，避免了“自热导致测量偏差”的问题；
- 宽温域稳定工作：-40℃~+125℃的范围覆盖了大部分民用、工业及汽车电子场景，即使在极端低温（如北方户外设备）或中高温（如发动机舱、工业烤箱）环境下仍能保持性能稳定；
- 小功率适配性：100mW额定功率满足多数低压、小电流电路需求，无需额外功率降额设计，简化了电路布局。
四、封装与物理规格
采用0603片式封装（对应公制尺寸1.6mm×0.8mm×0.8mm），具备三大优势：
- 高密度PCB适配：可在有限空间内集成更多元件，适合便携电子设备（手机、智能手表）、小型工业模块；
- 自动化生产兼容：支持表面贴装工艺，提高生产效率，降低人工成本；
- 抗振性强：片式结构紧凑，抗振动、抗冲击性能优于插件式电阻，适合车载、工业等振动环境。
五、典型应用场景
结合参数特性，该型号主要应用方向包括：
- 温度测量与控制：家电（冰箱、空调、电饭煲温度传感器）、工业设备（注塑机、锅炉温度监测）、汽车电子（车载空调、发动机冷却液检测）；
- 过温保护电路：电源模块（开关电源、LED驱动过温保护）、电池组（锂电池、储能电池异常报警）；
- 温度补偿电路：晶体振荡器（TCXO温度补偿）、无线通信模块（补偿频率漂移）；
- 便携电子：智能手机、平板、智能穿戴的电池温度监测（小封装适配紧凑空间）。
六、产品价值总结
ERTJ1VA220H通过高精度、宽温域、小体积的特性组合，解决了多数电子设备中“温度监测精度不足”“体积受限”“极端环境适应性差”等痛点，依托松下的品牌可靠性，成为消费电子、工业、汽车等领域温度相关电路的优选元件之一。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
