What are the key features of C1206X475K3RACTU?
- 4.7 µF capacitance in 1206 SMD package with X7R temperature-stable dielectric, maintaining ±15% capacitance over -55°C to +125°C operating range
- 25 V voltage rating with ±10% tolerance for use in 5 V to 12 V power supply decoupling, bypassing, and bulk storage applications
- KEMET FT-CAP flexiterm termination technology reduces board-flex cracking risk, extending capacitor life in high-vibration and thermal-cycling environments
What is C1206X475K3RACTU used for?
The C1206X475K3RACTU 4.7 µF X7R MLCC is used in power supply decoupling, bulk energy storage, and EMI filtering on industrial control boards, automotive ECUs, and communications equipment operating up to 25 V. Its X7R characteristic ensures predictable capacitance stability across the -55°C to +125°C temperature range, making it suitable for under-hood automotive applications and industrial environments. The 1206 package allows placement close to power-hungry ICs for effective high-frequency noise suppression at frequencies up to several MHz.

Frequently Asked Questions
What capacitance, voltage rating, and dielectric type does C1206X475K3RACTU offer for power supply decoupling?
The C1206X475K3RACTU provides 4.7 µF capacitance with a 25 V voltage rating and X7R dielectric in the 1206 SMD package. The X7R characteristic maintains capacitance within ±15% from -55°C to +125°C, making it effective for decoupling 3.3 V, 5 V, and 12 V rails in industrial and automotive power supply designs.
How does KEMET FT-CAP flexiterm technology in C1206X475K3RACTU prevent field failures in high-vibration applications?
KEMET's FT-CAP (flexiterm) termination uses a flexible polymer layer between the ceramic body and the PCB solder joint, absorbing PCB flex stresses that normally cause brittle MLCC cracking. This construction can tolerate PCB flexure up to 5 mm or more without fracturing, compared to standard MLCC terminations that typically fail at 2 mm flex, extending capacitor lifetime in automotive, industrial machinery, and handheld products.
When would a designer select C1206X475K3RACTU over a smaller 0805 4.7 µF capacitor for a 12 V rail bypass application?
The 1206 package of C1206X475K3RACTU handles 25 V rated voltage versus many 0805 alternatives rated at 10 V or 16 V for the same 4.7 µF value, providing a safer derating margin on 12 V rails (50% derating brings working voltage to 12.5 V). The larger 1206 body also offers lower equivalent series resistance (ESR) and better thermal dissipation for high-ripple current applications where the 0805 package may overheat.
