LOW INDUCTANCE CHIP CAPACITORS These MLC capacitors are specially designed to lower inductance by altering the aspect ratio of the termination in conjunction with improved conductivity of the electrodes. This inherent low ESL and ESR design improves the capacitor circuit performance by lowering the current change noise pulse and voltage drop. The system will benefit by lower power consumption, increased efficiency, and higher operating speeds. FEATURES • Low ESL • High Resonant Frequency • Low ESR • Small Size APPLICATIONS • High Speed Microprocessors • AC Noise Reduction in multi-chip modules (MCM) • High speed digital equipment B15 / 0508 Inches L W T E/B .050 ±.010 .080 ±.010 .050 Max. .010 ±.005 (mm) (1.27 ±.25) (2.03 ±.25) (1.27) (0.25±.13) 50 V 25 V NPO DIELECTRIC 16 V 50 V 25 V 16 V B18 / 0612 Inches L W T E/B .062 ±.010 .125 ±.010 .060 Max. .010 ±.005 (mm) (1.57 ±.25) (3.17 ±.25) (1.52) (0.25±.13) Dielectric specifications are listed on page 28 & 29.
