Radial Leaded MLCC

The choice of dielectric is largely determined by the temperature stability required

NPO (COG)
Ultra Stable Class I dielectric, with negligible dependence of electrical properties on temperature, voltage, frequency and time. Used in circuits requiring stable performance.

X7R (2X1)
Stable Class II dielectric, with predictable change of properties with temperature, voltage, frequency and time. Used as blocking, coupling, by-passing and frequency discriminating elements. This dielectric si ferroelectric and offers higher capacitance ranges than class 1.

Y5V (2F4) Z5U
General Purpose Class II dielectric with highest dielectric constant and greater variation of properties with Temperature and test conditions. Very high capacitance per unit volume and suited for bypass and coupling application as well as filtering, transient supression blocking, and charge storge application.

CAPACITANCE VALUE & TOLERANCE
Determined by circuit requirements, Note that chip prices decrease with lower capacitance value and looser tolerances.

CAPACITOR TERMINATION
Termination choice is largely determined by the chip attachment method Nickel barrier is recommended for units exposed to repeated solder cycles, to preclude leaching fo the termination. Silver is used on units to be lead attached, as the more ductile silver minimizes thermal cycling hazards.

VOLTAGE
Determined by circuit requirements. Units are designed to exceed the withstanding voltage specification, i.e., The user need not incorporate an additional salty margin.

PACKAGING
Units are available in bulk, some sizes on tape & reel. Specify if reeled.
