Package：

0603 (1608 Metric) 1.6 x 0.8 x 0.8 mm

Description

Product Overview

The 06033C221K4T2A is a multilayer ceramic capacitor (MLCC) manufactured by KEMET (a YAGEO company), featuring 220pF capacitance with ±10% tolerance at 25V DC using X7R dielectric in a 0603 (1608 Metric) surface-mount package. The X7R dielectric provides stable capacitance within ±15% over the -55°C to +125°C operating temperature range, making it suitable for bypass, decoupling, and filtering applications where moderate capacitance change is acceptable. The standard nickel barrier with matte tin termination ensures excellent solderability and compatibility with both lead-free and lead-containing soldering processes.

Product Introduction:06033C221K4T2A Product Introduction

The 06033C221K4T2A is a multilayer ceramic capacitor from KEMET, featuring 220pF capacitance with ±10% tolerance at 25V DC using X7R dielectric in a 0603 (1608 Metric) surface-mount package. The X7R dielectric provides stable capacitance within ±15% over the -55°C to +125°C operating temperature range, making it suitable for bypass, decoupling, and filtering applications where moderate capacitance change is acceptable. The standard nickel barrier with matte tin termination ensures excellent solderability.

Working Principle:06033C221K4T2A Working Principle

The 06033C221K4T2A operates as a passive MLCC capacitor:

1. Dielectric Layer: Multiple layers of X7R ceramic dielectric are interleaved with inner electrodes to build up the capacitance value. The X7R (Class II) dielectric provides a stable but not zero temperature coefficient, with capacitance change limited to ±15% over -55°C to +125°C.

2. Electrode Structure: Inner electrodes (typically nickel) are alternately connected to opposite end terminations, creating a monolithic structure with many capacitive layers in parallel.

3. Termination: The end terminations consist of a copper or silver-palladium base layer, nickel barrier plating to prevent solder leaching, and matte tin overplating for solderability.

4. Voltage Rating: The 25V DC rating defines the maximum continuous voltage that can be applied without dielectric breakdown. Voltage derating should be considered for AC applications.
