Product Use Conditions and Precautions

Storage Environment Requirements

Storage temperature: -10~ 40; Storage humidity: 75% RH.
Avoid storage in environments with corrosive substances and gases, direct sunlight, or radiation sources.
After opening the package, reseal and store. Shelf life is 1 year; re-inspection is permitted if the period is exceeded.

Transportation Requirements

Product stacking height should not exceed 4 boxes during storage or transportation.
Avoid strong collisions and drops during transportation.
Avoid direct or indirect exposure to rain, snow, hail, or seawater during transportation.

Installation & Use Precautions

Usage: Temperature measurement and control.
Suitable for conventional household and industrial products. For special equipment (aerospace, medical, military, etc.), please contact the company for confirmation.
Operate within specified maximum working temperature and power limits.
Avoid excessive current that causes self-heating and measurement errors.
Do not use if the product appears deformed or damaged.
Soldering: distance from encapsulation head 2mm, temperature <360, time <3sec.
Heat shrinking: Use a constant temperature oven at 110 for 10-12 minutes; avoid using a hairdryer.
Injection molding is generally not recommended due to high temperature and pressure; confirm parameters with the company if used.
Avoid extrusion or physical impact on the epoxy end as the core chip is a ceramic semiconductor.
When cutting leads, the cutting distance from the epoxy end should be no less than 10mm, and the end should be clamped.
Lead bending: bending radius 1mm, angle 90; confirm bending times with the company.
The product has general waterproofness. High humidity (>80%RH) or prolonged immersion may cause seepage, affecting insulation and resistance. Contact the company for enhanced waterproof protection if needed.
