Vishay Dale Thin Film
Sandwich, 25 mil Pitch, Dual In-Line Thin Film Resistor,
Surface Mount Network
FEATURES
• Lead (Pb)-free gold plated terminals standard
• Gold-to-gold terminations. External leads are
attached directly to gold pads on the ceramic
substrate by thermo-compression bonding (no
internal solder)
• Tighter tolerances than molded standards (0.01 %)
• Ceramic package with no cavity
• Flexibility of lead variations to save PC board space
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
A dual-in-line monolithic ceramic sandwich in a variety
of pin sizes (14 to 24) that allow higher resistance integration
than traditional chip and wire molded construction. In
addition, tighter resistance tolerances can be obtained over
traditional molded networks due to the elimination of
molding temperature and stress.
Note
* Lead (Pb)-containing terminations are not RoHS-compliant.
Exemptions may apply.
