Descripción

Productos

The 08055C104K4Z2A is a 0805-size MLCC from Yageo, featuring 100nF (0.1uF) capacitance, 50V DC rating, and X7R temperature characteristic (+/-10% over -55C to +125C). This is one of the most commonly used decoupling capacitor values in the electronics industry, providing effective high-frequency noise suppression for IC power supplies. The 0805 case size with 50V rating is a versatile choice for general-purpose bypass and filtering.

The 08055C104K4Z2A is a general-purpose 0805 MLCC from Yageo with 100nF capacitance, 50V rating, and X7R dielectric. As the industry’s most widely used decoupling capacitor value, the 0.1uF/50V/0805 combination provides effective high-frequency noise bypass for digital ICs, op-amps, and voltage regulators. The X7R dielectric maintains +/-10% stability over -55C to +125C, and the 50V rating provides ample derating for 3.3V and 5V systems.

The 08055C104K4Z2A operates as a multilayer ceramic capacitor using X7R (Class II) barium titanate dielectric. The 100nF capacitance combined with the 0805 package geometry provides a self-resonant frequency (SRF) around 50 MHz, where the capacitive reactance is at its minimum and the impedance is lowest (determined by ESR). This makes it highly effective as a decoupling capacitor for digital ICs operating at clock frequencies up to several hundred MHz, where it provides a low-impedance path for transient current demands. Below SRF, the capacitor behaves as expected (impedance decreases with frequency). Above SRF, the parasitic inductance dominates and impedance increases. For broadband decoupling, this capacitor is often paired with a larger bulk capacitor (e.g., 10uF) that handles low-frequency energy, while the 0.1uF handles high-frequency transients. The X7R dielectric has moderate DC bias dependence, retaining approximately 80% of nominal capacitance at 5V DC bias for the 50V-rated part.
