Glass-coated SMD thermistors with nickel barrier termination

9 April 2003 Passive Components

Delivering high sensitivity and high accuracy over a wide temperature range, the latest thermistors from BC Components (BCC) are fully covered with glass for environmental protection and feature nickel barrier contacts for improved soldering characteristics.

BCC's surface mount series 2322 615 3x and 2322 615 5x negative temperature coefficient (NTC) chip thermistors are ideal for temperature compensation, sensing, and protection circuits in applications such as battery chargers, switch mode power supplies and automotive systems.

Available in 0603 and 0805 surface-mount packages, the 2322 615 3x (0603) and 2322 615 5x (0805) NTC thermistors feature R25 values (resistance at 25°C) from 2,2 kΩ to 100 kΩ. Standard R25 tolerance options are ±2%, ±3%, ±5% and ±10% and a ±1% option is available on request. Calibration constant tolerance from 25°C to 85°C (β_25/85) is just ±1%, ensuring high sensitivity and high accuracy across a wide temperature range.
