Product Overview

The EPCOS B57421V2102J062 is an 0805 (2012) SMD NTC thermistor designed for high-precision temperature measurement and compensation. With a nominal resistance of 1kΩ at 25°C, it features a multilayer ceramic structure and nickel barrier termination, offering excellent long-term stability and resistance to soldering thermal shock. Ideal for temperature-sensitive applications in consumer electronics, industrial control, and automotive systems, it provides accurate temperature feedback and reliable compensation control.

Key Features

• High-Precision Temperature Sensing: ±5% resistance tolerance (J grade) and a B value (25/100) of 4000K ensure precise temperature-to-resistance conversion across -55°C to +125°C.
• High-Temperature Stability: Passes 1000-hour storage at 125°C with <2% resistance change, suitable for long-term operation in harsh thermal environments.
• Soldering Thermal Shock Resistance: <1% resistance change after soldering, compatible with reflow and wave soldering for stable performance during manufacturing.
• Miniaturized SMD Design: 0805 package (2.0×1.25mm) fits high-density PCBs, meeting the integration needs of miniaturized devices.
• Environmental Compliance & Reliability: RoHS-compliant and lead-free, certified to IEC 60068 standards, ensuring safety and reliability in demanding environments.
