KTY82/110,215 产品概述
一、产品简介
KTY82/110,215 系列为 NXP（恩智浦）提供的小型 PTC 温度传感元件，标称阻值约 1 kΩ（通常以 25°C 为参照），工作温度范围宽：-55°C 至 +150°C。器件采用 SOT-23 封装，适合表面贴装（SMT）应用。作为正温度系数（PTC）元件，其阻值随温度升高而增加，便于实现温度检测、补偿和过温保护等功能。
二、主要特点
- 标称阻值：1 kΩ（参考温度点）
- 温度范围：-55°C ~ +150°C，适应恶劣环境
- 封装：SOT-23，体积小、易于自动贴装
- PTC 特性：阻值随温升呈上升趋势，响应迅速
- 适用场景：工业、消费电子、电源与电池监测等
三、典型应用
- 温度检测与温度补偿（放大器、测量电路的热漂补偿）
- 过温检测与保护（与比较器或 MCU 配合实现报警/关断）
- 电源与电池管理中的温度监控
- 小型电子设备、家电与工业控制板上的局部温度采样
四、使用与设计注意事项
- 自热效应：检测电流会引起自热，选择分压电阻与测量电流时需在分辨率与自热之间权衡，避免显著提高器件温度。
- 布局：尽量将器件靠近被测目标，同时避免受大电流走线或热源直接影响。
- 阻值公差与线性度：PTC 通常非严格线性，应在系统层面做标定或使用查表方式换算温度。
- 焊接可靠性：SOT-23 可兼容标准回流焊工艺，但建议参照供应商的回流曲线以免超温或长时间高温影响特性和寿命。
五、封装与可靠性提示
SOT-23 小型封装利于高密度布局，但对机械应力和热循环敏感。在可靠性设计上，应考虑热循环测试、湿热与盐雾等环境试验，确认长期漂移与稳定性满足产品要求。
六、选型与实施建议
在选型时建议参考完整数据手册确认阻值-温度曲线、阻值公差、最大允许功耗和热时常数。实际应用中可用简单的上拉/分压网络接入 MCU ADC 或比较器；若需高精度温度读数，应进行系统标定并考虑温度线性化或查表校正。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
