Product Introduction:CKCA43X7R1H223M Product Introduction

The CKCA43X7R1H223M is a TDK CKC series 4-element ceramic capacitor array in a 1206 (3216 metric) package. Each element provides 0.022μF capacitance at 50V with X7R dielectric (±15% temperature stability from -55°C to +125°C) and ±20% tolerance. The isolated circuit configuration allows each capacitor to be used independently, replacing up to four discrete capacitors in a single placement. This reduces placement cost, improves TCR tracking between elements, and saves up to 30% PCB area per capacitor compared to discrete 0603 chips. Note: This part is listed as obsolete by some distributors.

Working Principle:CKCA43X7R1H223M Working Principle

The CKCA43X7R1H223M integrates four independent multilayer ceramic capacitors (MLCCs) in a single 1206 package using TDK’s CKC series array technology. Each capacitor element consists of alternating layers of ceramic dielectric (X7R formulation) and inner electrodes, fired together in a monolithic structure. The X7R dielectric is a Class II barium-titanate-based ceramic with a temperature coefficient of ±15% over the -55°C to +125°C range, making it suitable for bypass, decoupling, and filtering where moderate capacitance stability is acceptable. The isolated circuit topology means each of the four capacitors has two independent terminals, allowing them to be used in different circuit nodes. The array construction ensures matched temperature coefficients between elements, providing better tracking than four discrete capacitors from different production lots.
