SMD NTC Thermistor
SMD NTC Thermistor with Ni-Barrier Termination
Data sheet
B57431V2104J062
Applications
- Temperature measurement and compensation for mobile phone applications (e.g. battery pack,
TCXO, LCD display), automotive and data systems
Features
- Multilayer SMD NTC with inner electrodes
- Standard EIA chip size 0805
- Ni - Barrier termination (Ag/Ni/Sn)
- High accuracy: ±5% in resistance, ±3% in B-value
- Excellent long term ageing stability in high temperature and high humidity environment
- Superior resistance stability during soldering, therefore almost no change (<1%) during soldering
- The component is compliant with ROHS (DIRECTIVE 2002/95/EC OF THE EUROPEAN
PARLIAMENT AND THE COUNCIL of 27 January 2003 on the restriction of the use of certain
hazardous substances in electrical and electronic equipment)
