Selco's New High-Sensitivity NTC Surface Mount Chip Thermistors Offer Multiple Curve and Tolerance Combinations for Optimum Design Flexibility
ANAHEIM, Calif. - July 14, 2003 - Selco Products has added the Surface Mount Chip Negative Temperature Coefficient (NTC) Thermistors Series to its extensive line of thermal control products. Designed with surface mount capability for space saving economies, these cost-effective NTC thermistors provide high sensitivity response for a variety of temperature measurement and compensation, security, and monitoring applications. The new thermistors are offered in multiple curve and tolerance combinations to meet exact user specifications covering a wide range of resistance values and temperature coefficients.
Performance characteristics include resistance values of 25°C at 100,000 ohms with standard tolerances of ±1%, ±3%, and ±5%. Dissipation constant is 0.9mW/°C in still air, with a maximum power rating of 4-6mW@25° C. Other outstanding features include an operating temperature range of -40° C to 125°C, fast response time due to PCB surface mounting, and low capacitance.
The Surface Mount Chip NTC Thermistors offer a miniature size of just 0.8mm x 1.0 mm (Type 0603), allowing high density placement on the board. Uniform shape and size enables pick and place assembly for faster installation. Excellent long term stability characteristics make them ideally suited for critical applications in industries such as medical, military, aerospace, industrial telecommunications, computer peripherals, and scientific.
NTC Thermistors provide an economical alternative to many types of temperature control. Systems utilizing thermistors are less expensive to produce because fewer associated components - are required to provide a high performance system. They can also be ordered with tight tolerances to ± 0.05°C, eliminating costly calibration required by other types of temperature sensors.
The new thermistors are available in industry standard package sizes of 1206, 0805 and 0603, and are priced from $0.10 to $1.21 each with lead times from 4 - 5 weeks for deliveries.
