Key Features
- 47 nF capacitance with 10% tolerance in 2220 SMD package for robust decoupling and filtering
- FT-CAP (Flat Terminal) construction eliminates flex-cracking risk in high-vibration or thermally stressed environments
- Temperature-stable dielectric maintains capacitance within rated limits across extended industrial temperature ranges
Applications
The C2220X473KDRACTU is suited for decoupling, bypass, and filtering applications in power converters, motor drives, and industrial control modules where capacitance stability under thermal cycling is critical. Its FT-CAP (Flat Terminal) construction resists cracking caused by PCB flex and thermal shock, extending service life compared to standard MLCC terminations. The 2220 case size accommodates higher voltage ratings, making it applicable in 48 V bus filtering and DC-link snubber circuits.

Frequently Asked Questions
What makes the FT-CAP construction of C2220X473KDRACTU more reliable than standard MLCC terminations?
FT-CAP (Flat Terminal) construction uses a flexible metal terminal instead of a rigid solder joint, absorbing PCB flex and thermal expansion stresses. In high-vibration industrial environments or automotive designs with temperature swings exceeding 125°C, standard MLCC terminations can crack at the ceramic-to-terminal interface, causing open-circuit failures that the FT-CAP design prevents.
How does the temperature-stable dielectric in C2220X473KDRACTU benefit power supply decoupling circuits?
A temperature-stable dielectric keeps the 47 nF capacitance within a narrow tolerance band across the operating temperature range, typically -55°C to +125°C or beyond. In power supply decoupling designs, this stability ensures that the capacitor's impedance at target filtering frequencies (such as 1 MHz to 100 MHz) does not vary significantly with PCB temperature, preventing noise breakthrough under thermal load.
Which 2220 MLCC alternatives should engineers consider if C2220X473KDRACTU is on long lead time?
Engineers can evaluate functionally equivalent 2220-package, 47 nF, temperature-stable MLCCs from TDK, Murata, or Vishay with matching voltage ratings and dielectric grades. When substituting, verify that the replacement also carries an FT-CAP or flex-termination feature if the application involves PCB bending or thermal cycling above 85°C, since standard termination units in 2220 size may be more susceptible to flex-cracking.
