The TDK CGA4J3X7S2A105KT0Y0N is an automotive-grade multilayer ceramic chip capacitor (MLCC) from TDK’s CGA series. It provides 1µF capacitance, a 100V DC rating, and ±10% tolerance. TDK’s current standard orderable equivalent is CGA4J3X7S2A105K125AB, which is identified as an automotive-grade, mid-voltage MLCC and is AEC-Q200 qualified.
The capacitor uses an X7S dielectric characteristic and operates over -55°C to +125°C, with capacitance variation specified within ±22% across the temperature range. Its 100V rating makes it suitable for automotive power rails, filtering, bypass, decoupling, and DC-DC converter applications.
The device is housed in an 0805 / 2012 Metric package, measuring approximately 2.00 ±0.20 × 1.25 ±0.20 × 1.25 ±0.20mm. Maximum dissipation factor is 5%, while minimum insulation resistance is 500MΩ.
TDK currently lists the corresponding CGA4J3X7S2A105K125AB as Production. It supports both reflow and wave soldering and is supplied on a 180mm embossed plastic tape reel with 2,000 pieces per reel. TDK also marks the product as RoHS and REACH compliant, halogen-free, and lead-free.
