Multilayer Ceramic Capacitor (MLCC)[83]

Updated: 2026-10-15

Overview

The CC0603KRX7R7BB225 is a multilayer ceramic capacitor (MLCC) designed for surface-mount technology (SMT) applications. As part of the 0603 size category (1.6mm × 0.8mm), it offers an excellent balance between compact size and performance. The component utilizes X7R dielectric material, which provides ±15% capacitance tolerance across a -55°C to +125°C temperature range. This makes it particularly suitable for applications requiring stable capacitance under varying environmental conditions. Manufactured using advanced ceramic technology, the capacitor features nickel barrier electrodes and a fully solderable termination system. The 22µF capacitance rating at 6.3V makes it one of the highest-value options available in the 0603 form factor. Industry-leading manufacturers produce this component with consistent quality, making it a reliable choice for commercial and industrial electronics design.

Structure and Working Principle

The CC0603KRX7R7BB225 consists of alternating layers of ceramic dielectric material and metal electrodes, creating a parallel plate capacitor structure within a monolithic ceramic body. The X7R dielectric formulation provides stable Class II characteristics, meaning it offers medium capacitance stability with moderate temperature dependence. The internal structure is designed to minimize parasitic inductance, making it effective for high-frequency applications. When voltage is applied across the terminals, electrostatic energy is stored in the dielectric layers. The capacitor operates by accumulating charge on its electrodes, with the ceramic material preventing current flow between layers. The termination system uses a nickel barrier under a tin plating, ensuring excellent solderability while preventing silver migration issues common in high-humidity environments.

Key Features

This capacitor stands out for its exceptional volumetric efficiency, packing 22µF capacitance into a tiny 0603 footprint. The X7R temperature characteristic ensures capacitance remains within ±15% of nominal value across the entire operating range. With an equivalent series resistance (ESR) typically below 100 milliohms, it performs well in power supply filtering applications. The component exhibits excellent DC bias characteristics, maintaining more than 70% of rated capacitance at maximum rated voltage. It also features low microphonic effects, making it suitable for audio applications. RoHS compliance and compatibility with lead-free soldering processes (up to 260°C peak temperature) make it ideal for modern electronics manufacturing.

Application Areas

Primary applications include decoupling in digital circuits (particularly near IC power pins), filtering in switching power supplies, and energy storage in portable devices. The capacitor is commonly found in smartphones, tablets, IoT devices, and automotive electronics where space constraints demand high-capacitance SMT components. In RF circuits, it serves as a bypass capacitor to shunt unwanted high-frequency noise to ground. Industrial applications include motor drives, power inverters, and control systems where stable capacitance under temperature variations is critical. Medical electronics designers value this component for its reliability in diagnostic equipment and patient monitoring devices.

Maintenance and Precautions

Avoid mechanical stress during handling and assembly, as ceramic capacitors are brittle and susceptible to cracking. Use proper soldering profiles with peak temperatures not exceeding 260°C for lead-free processes. When designing circuits, maintain recommended clearance from heat sources and consider thermal expansion effects. In applications with significant vibration or flexing (such as wearable devices), consider additional underfill or strain relief. Do not exceed rated voltage or reverse polarity, as this can degrade performance or cause failure. For optimal performance in high-frequency applications, minimize trace lengths between the capacitor and the component being decoupled.

B2B Procurement Guide

For bulk purchasing, verify manufacturer authenticity through authorized distributors to avoid counterfeit components. MOQ typically starts at 3,000-5,000 pieces, with price breaks at 10,000 and 50,000 unit quantities. Lead times vary between 8-12 weeks for standard production runs, though some distributors maintain stock of common configurations. When specifying this component, provide complete part number (including packaging code, e.g., tape-and-reel). Consider alternative manufacturer equivalents (like Murata GRM188R70J226ME47 or Samsung CL10A226KP8NNNC) for supply chain flexibility. Test certifications may include AEC-Q200 for automotive applications or MIL-PRF-123 for military-grade requirements when available.
