GLASS ENCAPSULATED CHIP Thermistors are a high quality line of Low Cost, Hermetically Sealed, glass encapsulated units that evolved from Fenwal Electronics, Inc.'s highly successful and field-proven Standard Chip Series. Added to the feature of "True Low Cost" is "Delivery from Stock" in high volume. They are designed to cover the full temperature range of -60° C to +300° C. The uniform dimensions are ideally suited for automated assembly. A rugged sensor, it is designed for any application which demands reliability at a Low Cost. The tinned copper clad steel leads are both solderable and weldable, and leads may be formed/cut for radial lead applications.
Fenwal Electronics’ Glass Encapsulated Chip Thermistors are available to our customers Bulk Packaged or on Tape and Reel.
