PRODUCT FEATURES
ORDERING OPTIONS
RoHS EU Compliant
Rated operating temperature of 130°C.
Ceramic Material: Aluminum Oxide
Porch configuration for high strength lead wire connection.
Superior nickel diffusion barriers on elements.
High strength for rugged environment.
RTV sealing option available.
Lapped option available for multiple module applications.
OPERATION CAUTIONS
For maximum reliability, storage and operation below
130°C in a non‐condensing environment is recommended.
To minimize thermal stress, use linear/proportional
temperature control or a similar method rather than an
ON/OFF method.
