BY278
BY278 is Damper diode manufactured by NXP Semiconductors.
FEATURES
- Glass passivated
- High maximum operating temperature
- Low leakage current
- Excellent stability
- Available in ammo-pack
- Also available with preformed leads for easy insertion. APPLICATIONS
- Damper diode in high frequency horizontal deflection circuits up to 16 k Hz. DESCRIPTION
Rugged glass package, using a high temperature alloyed construction.
This package is hermetically sealed and fatigue free as coefficients of expansion of all used parts are matched.
